The default settings can be changed to suit specific installation requirements via the ExtendView Utility, the embedded Web server, or via a Telnet connection to the serial server’s internal console. The factory default settings can be easily restored at any time by performing a cold reset (press and hold the pushbutton on the device for more than five seconds). Port Parameters and Modbus Settings Parameter Description Settings CHARACTER bits per character 7, 8 (default) FLOW flow control NO (default), XO, CT PARITY parity NONE (default), EVEN, ODD, MARK, or SPACE SPEED baud rate (bits per second) 300, 600, 1200, 2400, 3600, 4800, 7200, 9600 (default), 14400, 19200, 38400, 57600, 76800, 115200 (console port default), 230400, 460800 STOP stop bits per character 1 (default), 2 MODE line mode (serial port protocol) 232 (default), 422, 485, 485HD, Disabled ECABLE E-Cable mode (for TCP connections) Enable, Disable (default) ECADDR E-Cable destination IP address (set by user) ECONN E-Cable connection attempt time 20 seconds ECPORT E-Cable destination IP port number 9100 (default), or set by user MULTI multidrop protocol Host (default), Modbus MBTYPE Modbus attached device type RTU slave (default)2, ASCII slave MBINIT Modbus initialization delay interval 100 – 3276 ms (default = 100 ms) MBAUTOID Modbus auto slave ID Enable (default)1, Disable MBCHARTMO Modbus character timeout interval 10 – 3000 ms (default = 100 ms) MBMSGTMO Modbus message timeout interval 10 – 3000 ms (default = 1000 ms) (N/A) Modbus/TCP Exception handling Enable, Disable (default) Configuration Notes 1. The Modbus/TCP protocol contains a “Unit ID” field to identify multiple Modbus slave devices that are accessible at a single IP address. When the Modbus/TCP command contains a Unit ID, the Modbus Gateway can pass the Unit ID to Modbus serial devices, which allows multiple serial devices to be linked with a Modbus Gateway. When Auto Slave ID is enabled, a unit ID will be assigned automatically. If the Auto Slave ID is disabled, a unit ID (any number between 1 and 247) must be manually assigned in the Slave ID field. 2. When the Modbus serial protocol is set to Modbus/RTU, the Serial Server is ready to receive connection requests from Modbus/TCP master devices. Each message packet is determined by a character timeout. An incorrect character timeout may cause a CRC (Cyclic Redundancy Check) checksum error. Modbus ASCII slave mode functions the same as Modbus/RTU slave mode, except that the data format is Modbus/ASCII. 3. The Modbus/TCP Exception is in effect when the Modbus Gateway connects a Modbus/TCP Master with Modbus serial slave devices. When the Modbus Gateway cannot get a response from Modbus serial devices, the Modbus serial protocol will not respond to the master device. However, the TCP protocol has a longer waiting time, which could cause a network traffic problem for Modbus/TCP. For this reason, the Modbus Gateway can automatically send a Modbus exception code 16 to the Modbus/TCP master device when there is not response from the Modbus serial slave devices, thereby making overall network communication much more efficient.
Serial Server User’s Guide Document #40179-120 Rev. X5 2-1 Section 2: Hardware Installation Install the TROY Serial Server (for wired and wireless models) Follow the steps below to install the TROY Serial Sever. In most cases, the Serial Server’s factory default settings should be sufficient for most serial connections; however, some of the configuration settings may have to be changed for your particular installation. The TROY Serial Server can be wall mounted, set on the desktop, or mounted using the optional DIN rail kit (available from TROY). 1. Before attempting to install the TROY Serial Server, make sure you have installed and set up your serial device as described in the documentation that came with the device. 2. Write down the 12-digit MAC (Media Access Code) address printed on the label located on the bottom of the Serial Server (for example: 004017023F96). You may need this number in order to configure the Serial Server. 3. Connect the Serial Server to your serial device using a standard PC-compatible 9-pin (DB-9) serial cable for RS-232 type devices (refer to Appendix A for pinout descriptions). A custom cable may be required for RS-422 and RS-485-type serial devices. For RS-422/RS-485-type devices, a 120-ohm terminating resistor may be required at the receiving end of a differential pair if the device is at the end of the cable (refer to Appendix C for detailed information). 4. Plug the Serial Server power supply adapter into a suitable AC receptacle, and then plug the power supply cable into the Serial Server. The Serial Server will run through a sequence of power-up diagnostics for a few seconds.  If the Serial Server is operating properly, the LEDs will blink momentarily and then go out, the yellow and green LEDs will illuminate if the wireless network is active, and the orange LED will illuminate, indicating the device is receiving power (refer to page 1-4 for detailed LED status descriptions).  The unit powers up in the Normal mode, which provides for connection from the network to device(s) connected to the serial port of the Serial Server.  If the orange LED blinks continuously in a regular pattern, a problem exists. If this is the case, try powering the unit OFF and then ON again. If the problem persists, refer to the Troubleshooting section in this User’s Guide. 5. Connect the Serial Server to your network through a switch or hub using a category 5 (CAT5) Ethernet cable. The Serial Server’s IP address must be configured before a network connection is available. If your network offers DHCP (Dynamic Host Configuration Protocol), the Serial Server will automatically search for a DCHP server upon power up and obtain an IP address. If your network does not offer DHCP, a static (fixed) IP address must be assigned (see your system administrator for assistance). In most cases, a fixed IP address is preferred because a DHCP server may not always assign the same IP address to the Serial Server when the Serial Server is powered ON. The Serial Server also supports the following protocols. See your system administrator for help.  arp  rarp  BootP NOTE: The IP address must be within a valid range, unique to your network, and in the same subnet as your PC(refer to page A-1 for a list of TCP port connections). NOTE: For wireless Serial Servers, if a wired connection is established to the unit, the wireless link will be disabled.

Configuring the Serial Server via an Ethernet Connection For Microsoft Windows operating systems, the TROY ExtendView Utility is the recommended method of configuring one or more Serial Servers on your network. Once the Serial Server obtains an IP address (occurs automatically when the unit is powered ON and connected to a DHCP netowrk), the ExtendView Utility’s auto-discovery feature will search for and locate all Serial Severs on the network and then display the IP address for each discovered Serial Server. USING THE EXTENDVIEW UTILITY TO CONFIGURE THE SERIAL SEVER (WINDOWS OPERATING SYSTEMS): 1. Start the ExtendView Utility by clicking on Start, Programs, TROY GROUP, and then ExtendView. 2. When the Welcome screen appears, click on Next, choose any name for your View Name, select Automatically create a view with default settings (or configure the view to your preferences), and then click on Finish. 3. Right-click on the Serial Server that you want to configure from the displayed list, and then left-click on Configuration. The default Serial Server name is TWC_xxxxxx (where xxxxxx is the last six digits of the MAC address from the label located on the back of the Serial Server). 4. If you are using TCP/IP (recommended for Windows) and you do not have a DHCP server (see note below), you will need to manually assign a valid IP Address (if you are not sure what IP address is valid, ask your network administrator), and then click on OK. 5. Configure the 802.11b wireless settings (for wireless models only). To operate on an 802.11b network, the Serial Server configuration must be set to the same configuration as your wireless network to allow the Serial Server to communicate over your wireless network. All nodes of a wireless network need to have the same settings to allow communication between the devices.  wireless mode (ad-hoc or infrastructure)  SSID channel  data rate  wireless security settings (WEP keys, 802.1x settings, etc.) NOTE: If you are using DHCP on your network, the Serial Server should have acquired valid IP settings at this point and no further configuration is necessary. However, for most installations, a static IP address is preferred. If your DHCP server does not allow the Serial Server to keep its assigned IP address permanently, then you must manually assign an IP address. In this case, use a static IP address outside the range reserved for DHCP (see your DHCP server documentation for details). To assign a static IP address, right-click on the Serial Server in the menu, and then select Configuration. On the TCP/IP tab, under IP Address Resolution, select Set Permanent, and assign a valid static IP address for your network. Click on OKto save the new settings.
Serial Server User’s Guide Document #40179-120 Rev. X5 3-3 USING THE WEB BROWSER INTERFACE TO CONFIGURE THE SERIAL SERVER (NON-WINDOWS SYSTEMS): To configure the Serial Server using non-Windows operating systems (e.g., Unix systems), a standard web browser (e.g., Internet Explorer or Netscape Navigator) can be used to access the Serial Server’s embedded Web (HTTP) server pages, which contain the Serial Server’s configuration options. No additional software is required. 1. Ensure your PC is connected and has access to your network. 2. Connect an available Ethernet cable from your network hub to the Serial Server. Ensure the Serial Server is powered ON. 3. Connect the Serial Server to the desired serial device, and ensure that the device is powered on and ready. If the Serial Server is connected to a serial device that cannot display or print ASCII characters, then it is recommended that another serial device capable of displaying or printing ASCII characters be temporarily connected to the Serial Server in order to view the IP address assigned by the DHCP server to the Serial Server. 4. With the serial device and Serial Server switched on and ready, press the Test button on the Serial Server to send the Serial Server’s configuration data to the connected serial device. The serial device should display or print the current IP address assigned to the Serial Server by your network DHCP service. If your network does not use DHCP, then the Serial Server will have the default IP address of 192.0.0.192. In any case, your computer must use an IP address other than the one used by the Serial Server in order to establish a connection between the two devices. 5. Configure the 802.11b wireless settings (wireless Serial Servers only). To operate on an 802.11b network, you must set the Serial Server’s wireless mode (ad-hoc or infrastructure), SSID channel, data rate, and security settings (WEP keys, 802.1x settings, etc.) to the same configuration as the wireless network you want the Serial Server to communicate on. All nodes of a wireless network need to have the same settings in order to communicate with each other. 6.

NOTE: It is not necessary to change your computer’s settings if you are configuring the print server’s settings via an Ethernet connection. First-Time Configuration of the Wireless Serial Server Using 802.11b (wireless models only) Although the Serial Server can be configured using a wireless connection, it is recommended that the Serial Server be initially configured using a wired connection as described on the previous pages. The Serial Server’s wireless network interface supports all modes of 802.11b at 1, 2, 5.5, and 11 Mbps. The wireless network is only active if the Serial Server is not connected to a wired network. If a wired link is established to the Serial Server, the wireless link is automatically disabled. To configure the wireless Serial Server for the first time from a computer via an 802.11b wireless connection, you will need to temporarily change your computer’s settings to match the default settings of the Serial Server as follows:  Wireless Mode: Ad-Hoc (sometimes referred to as Peer-to-Peer)  Channel: 11  SSID (or wireless network name): serserv You should now be able to configure your Serial Server using either the ExtendView Utility or the Web Browser Interface as described in the previous sections. In addition to the standard 802.11 WEP (Wired Equivalency Privacy), TROY provides additional wireless security options (refer to the security addendum for detailed information).
Serial Server User’s Guide Document #40179-120 Rev. X5 3-6 Verifying the Serial Server’s Connection to a Serial Device 1. Verify that both the Serial Server and the connected serial device are powered on and ready, and that a serial cable is properly connected between the Serial Server and serial device (i.e., transmit signal output from the Serial Server going to the receive signal input on the serial device, ground leads connected together, etc.). 2. Verify that the Serial Server’s port settings (i.e., baud rate, flow control, character bit size, parity, etc.) exactly match the settings of the connected serial device’s port. 3. If the serial device connected to the Serial Server is able to display or print ASCII characters (such as terminal emulator or serial printer), then communication between the devices can be verified by pressing the Test button on the Serial Server for about one second (but less than five seconds), which will initiate the output of configuration data from the Serial Server to the connected serial device.  If communication has been successfully established between the two devices, the serial device should be able to display or print the Serial Server’s configuration data.  If no data is displayed or printed, verify that both devices are powered ON, are properly connected using a suitable serial cable, and are using compatible serial port parameters. The two most common serial communication problems are due to the either the cabling and/or mismatched serial port parameters. If you are unable to establish a working serial connection between the Serial Server the connected serial device, refer to the troubleshooting section in this User’s Guide. For additional troubleshooting information, refer to the troubleshooting section in this user’s guide, or contact TROY Technical Support at (800) 332-6427, or visit the TROY web site at http://www.troygroup.com, or send an e-mail to technicalsupport@troygroup.com. Customers outside the United States, please call (304) 232-0899. European customers, please call +49 (0) 7032-9454-21, or send an e-mail to support@troygroup.de for assistance. NOTE: Before attempting to use the Serial Server, you must verify the connection between the Serial Server and theconnected serial device. If this connection is not working, you will not be able to send and/or receive data from theconnected serial device. NOTE: If the Serial Server is connected to a serial device that cannot display or print ASCII characters, then it is recommended that another serial device capable of displaying or printing ASCII characters be temporarily connected to the Serial Server in order to verify the serial connection. After successful communication is verified using the temporary serial device, reconnect the original serial device, making sure that the original serial device is configured with serial port parameters that match the tested connection.
Serial Server User’s Guide Document #40179-120 Rev. X5 3-7 Changing the Serial Settings In order to establish communication between the Serial Server and a serial device, the serial settings for both devices must match. The serial settings can be changed using ExtendView (recommended), the web browser interface, or the Serial Server’s internal configuration console (refer to the previous sections for the installation and use of these utilities). Refer to page 1-5 for a list of factory default settings. USING THE EXTENDVIEW UTILITY TO CHANGE THE SERIAL SETTINGS: 1. Start the ExtendView Utility by clicking on Start, Programs, TROY GROUP, and then ExtendView. 2. From the main menu, click on Options, and then click on Configuration. 3. Click on the Output Port tab, and then click on the Serial Settings button. 4. After configuring the serial settings, click on OK to continue. Changing the Baud Rate In some cases it may be necessary to change the baud rate of the serial sever in order to match the baud rate of a particular serial device where the baud rate is fixed. Baud is a measurement of transmission speed in asynchronous communication and represents the number of bits that are actually being sent over the media, not the amount of data that is actually moved from one device to the other. The TROY Serial Server supports baud rates from 300 to 460800 bps (refer to page 1-5 for the specific baud rates supported). To ensure communication between connected serial devices, all other serial port parameters (mode, character bits, parity, etc.) must be identical for each serial device. Changing the Serial Port Protocol The Serial Server’s serial port protocol (data transmission mode) can be changed to match the particular characteristics of the connected serial device’s UART (Universal Asynchronous Receiver/Transmitter). The TROY Serial Server supports the following serial port protocols. Each of these protocols is capable of handling data transfer speeds of 1 Mbps or better. Protocol Description RS-232 an interface between data terminal equipment and data communications equipment employing serial binary data interchange over a wired connection with a maximum range of 50 feet (16.5 meters). RS-422 a data transmission system using balanced differential signals (voltages) to send serial binary data over a wired connection with a maximum range of 4,000 feet (1.2 km). RS-485 / RS-485HD a data transmission system using balanced differential signals (voltages) to send serial binary data over a wired connection with a maximum range of 4,000 feet (1.2 km). As many as 32 driver/receiver pairs can share a multidrop network (4-wire at full duplex or 2-wire at half duplex). Many characteristics of the drivers and receivers are the same as RS-422.
Serial Server User’s Guide Document #40179-120 Rev. X5 3-8 Using the Modbus Protocol Modbus is a widely used industrial device communications protocol that provides “client/server” communications between devices connected on different types of buses or networks. The TROY Serial Server supports the Modbus serial line version of the protocol used for communicating with many types of industrial devices (e.g., instruments, meters, controllers, switches, etc.) over a serial-to-Ethernet connection. In general, the TROY Serial Server operates as a transparent device between the host (master device) and the connected serial devices (slaves), sending and receiving data to and from one or more slave units (up to a maximum of 32 slave serial devices). The Serial Server uses the RS-232 and RS-485 serial port protocol (using a 9-pin connector) for Modbus communication. Serial Transmission Modes Two connection protocol options are available between the TROY Serial Server and the serial device:  RTU (Remote Terminal Unit) Mode – allows for greater character density, which allows for better data throughput than ASCII mode. However, each message must be transmitted in a continuous stream of characters.  ASCII (American Standard Code for Information Interchange) Mode – is used when the physical communication link or the capabilities of the serial device do not allow conformance with RTU mode requirements. Typical Modbus Applications Many traditional Modbus devices can talk over an RS-485-type serial port provided that the transmission distance between the serial device and the TROY Serial Server does not exceed 4,000 feet (1.2 km). When using the RS-232-type serial port, the connection between the TROY Serial Server and the serial device cannot exceed 50 feet (16.5 meters), which is sufficient for short point-to-point communications. Using the TROY Serial Server configured as a Modbus master device, up to 32 Modbus slave devices can be placed on the same Modbus network using the RS-485-type serial port. In a master/slave configuration, the master serial device will always initiate communication with the slave devices, and the slave devices will never talk to each other. In unicast mode, the TROY Serial Server can only address an individual slave at one time with each slave having a unique network address. In this mode, when addressed by the master, each slave returns a reply to the master device. In broadcast mode, the TROY Serial Sever can address all the slave units simultaneously; however, in this case, the slave devices do not send a reply to the master device. Changing the Modbus Settings In order to establish communication between the Serial Server and a serial device using the Modbus protocol, the Modbus settings for both devices must be compatible. The Serial Server’s Modbus settings can be changed using the TROY ExtendView Utility (recommended), the web browser interface, or the Serial Server’s internal configuration console (refer to page 3-1 for detailed application use).
Serial Server User’s Guide Document #40179-120 Rev. X5 4-1 Section 4: Troubleshooting Introduction This section describes procedures for troubleshooting problems you may encounter with the TROY serial server, and is divided into the following sections:  Installation Problems  Intermittent Problems  Protocol-Specific Problems Troubleshooting Installation Problems If you cannot access the connected serial device via the Serial Server, first check the network connection and cabling.  Check the physical cabling to ensure all cables are plugged in (Ethernet and DB-9 serial cable).  If the appropriate LEDs are not illuminated, then there is probably a bad 10baseT or 100baseTX cable, or the hub port is bad. If possible, try a different cable and hub port, or try connecting a different device to the cable.  Verify that you using the correct values for both IP Address and Port Number. A common mistake is to assume the TCP port number is the "device number" on the server.  If you are using a hub, verify that the hub port is operating correctly by trying the Serial Server on a different port. Troubleshooting Network Configuration Problems  If you are using TCP/IP, make sure that your computer and the serial server are on the same IP segment or can reach each other with a PING command from the host. The IP address you assign to the serial server must be on the same logical network as your host computers (e.g., if your computer has an IP address of 192.189.207.3, the Serial Server should have an IP address of 192.189.207.x, where x is an integer between 1 and 254), or you must properly configure your router address to work with the serial server.  If your serial server is set to Auto or DHCP for obtaining an IP Address, it is possible that the serial server’s IP address can change. Either configure your DHCP server to give the serial server a permanent lease, or configure the print server to be on a STATIC IP address outside the scope of the DHCP addresses.  The problem may be the result of mismatched or duplicate IP addresses. Verify that the IP address is correctly loaded into the TROY serial server (via the displayed or printed configuration information or through the remote console), and make sure that no other nodes on the network have this address (duplicate addresses are the biggest cause of TCP/IP connectivity problems). If the IP address is not correct, then check whether the loading procedure was properly executed.  Also verify that the host computer and the serial server are either on the same subnet (for example, if the serial server has a subnet mask of 255.255.255.0, the host must have the same subnet mask) or that the router is properly configured to pass data between the two devices.  If the wrong IP address is loaded, check your network for file servers that have DHCP, BOOTP, or rarp enabled, and make sure that these file servers are not set up to load IP addresses into the serial server.
Serial Server User’s Guide Document #40179-120 Rev. X5 4-2 Troubleshooting Windows Problems  If you are having trouble accessing the connected serial device through Windows, ensure you can ping the TROY Serial Server using the DOS command PING ipaddress, where ipaddress is the IP address of the TROY Serial Server. If you cannot ping the serial server, you will not be able to access the serial device.  If you are running COM port emulation software and the software reports an error, verify that the correct serial/IP COM port is being used when the application runs. Verify that your application’s COM port settings have been changed to use the Serial/IP COM ports. Troubleshooting Wireless Configuration Problems  Verify that your PC’s wireless adapter and/or access point is configured properly – note the settings, paying special attention to the wireless mode, SSID or network name, WEP or security, and IP address settings so you can configure your serial server to the same wireless settings.  Make sure you have a good wireless signal from your PC and from the serial server, that the serial server is within range (90 meters or 300 feet), and that it is away from metal objects and other devices that generate radio signals (like Bluetooth devices, cordless phones, and microwave ovens).  Make sure your computer is set to infrastructure mode if you are connecting through an access point, or ad-hoc (802.11) if you are connecting to the serial server without an access point. See the documentation for your wireless adapter for details.  If you want to use WEP encryption or password protection for your wireless network, and your wireless adapter or access point normally uses a password or passphrase instead of WEP, it should allow you to enter 0x followed by a 10-digit key (for 40-bit or 64-bit WEP) or 26-digit key (for 128-bit WEP) in hexadecimal format (0-9 or A-F).  If you are experiencing slow performance or are having intermittent problems connecting, try changing the RF channel of your wireless network. The RF channel can be changed via the ExtendView Utility or the web browser configuration utility for the serial server. See your wireless adapter and/or access point documentation for more information. When changing the RF channel, it is recommended that you select a channel that is at least three channels lower or higher than any other wireless networks within range.

Serial Server User’s Guide Document #40179-120 Rev. X5 D-1 Appendix D: Alternate Power Source Configuration The TROY Serial Server can be configured to use a +5 VDC input via Pin 9 on the DB-9 connector to power the unit instead of using the supplied power supply module. To configure the serial server to accept power via Pin 9, the serial server case must be opened, and the shunt at JP3 must be moved from Pins 2 and 3 to Pins 1 and 2 (towards the +5 indicator). The voltage measured at Pins 9 and 5 must be at least +4.8 VDC and not greater then +5.2 VDC. Minimum supply current is 800 mA and 500 mA for the TROY wireless and non-wireless serial server, respectively. If Pin 9 is utilized for power, it is recommended that shielded cable be used to minimize EMI (Electro-Magnetic Interference).
