14 Modes of Operation EZReader HF & EZTune Antenna Installation & User Guide Accu-Sort Systems, Inc. Trigger Inputs 1 and 2 Two optically isolated inputs or two non-isolated inputs are available on the I/O Port. These inputs are used when the unit is in Hardware Trigger Mode of operation and allow the unit to operate autonomously. When using isolated inputs user must supply both positive and negative voltage references. When using non isolated inputs user must connect to sink output of trigger device (active low). A current limited (100 ma max combined Trigger 1&2) 12VDC connection is available for purposes of providing power to low current consuming devices such as a photo-eyes. Non isolated inputs are internally pulled to +5VDC through a 2.2k ohm resistor. NOTE: Avoid sourcing any current into the Non-Isolated Trigger inputs. Failure to do so can damage unit. Outputs 1 and 2 Two Solid-State Form A Relay Outputs are available on the I/O Port. These outputs can be configured by the user to close on various conditions such as valid or invalid tag reads. The outputs can also be controlled by remotely by the user. NOTE: Relay Outputs are capable of switching DC voltages(30 VDC max@250 ma) only. Applying AC voltages will damage unit.

EZReader HF & EZTune Antenna Installation & User Guide Installation Requirements 19 Accu-Sort Systems, Inc. Antenna Mounting General Guidelines To achieve optimum performance from the EZReader HF, the antenna should be mounted as far from metal objects as possible. The RF energy generated by the Reader/Antenna combination to communicate with the RFID tags is called the near field. The near field is the magnetic portion of the RF field and can be influenced by surrounding metallic objects. These metallic objects if located close enough to the antennae and are of the right shape and position can create eddy currents, which diminish and in some instances can totally cancel out the reading ability of the antenna. These metallic objects also will detune the antennae which in turn will cut down on the power transfer between reader and antenna leading to less then optimum performance. To cover all possible antenna mounting possibilities is beyond the intent of this document, but an example of one way to help reduce the influence of metallic objects on the antenna is shown below. The 5” x 16” antenna is shown in this example being mounted in a roller conveyor.

EZReader HF & EZTune Antenna Installation & User Guide Installation Requirements 21 Accu-Sort Systems, Inc. Notes:
EZReader HF & EZTune Antenna Installation & User Guide Modes of Operation 23 Accu-Sort Systems, Inc. Modes of Operation The EZReader HF modes of operation can be divided into three categories. The reader can be in Setup mode where the user can change parameters, or it can be in HardwareTrigger mode where the unit acts only on trigger inputs, or it can be in Host Control mode where the unit functions based on commands it receives from a Host. See following sections for in depth details on each mode.
24 Modes of Operation EZReader HF & EZTune Antenna Installation & User Guide Accu-Sort Systems, Inc. Setup Mode All of the user changeable parameters can be configured in setup mode. These settings will be stored in non-volatile memory only if they are saved after changing. Due to the vast number of user defined parameters and their interaction Accu-Sort recommends using the EZReader HF Interface GUI for configuring the reader. See GUI section. Entering Setup Mode Setup mode can be entered by using the GUI and either connecting a 1 to 1 Serial Cable (included with the EZReader HF Accu-Sort Part # 0111343001) between your PC and the Reader or thru a Ethernet connection. It is recommended to use the Serial connection the first time as you do not need to know any of the units Network settings to connect. When choosing to use the Network Setup connection you will need to configure your LAN settings to be compatible with the unit’s settings. The default Network settings are as follows: IP Address: 192.168.178.252 Net Mask: 255.255.255.0 Gateway: 192.168.178.252 The Serial SETUP Port settings are fixed as follows: 57600, N81 The data format of this port is also fixed and is as follows: <STX><Message><ETX>
EZReader HF & EZTune Antenna Installation & User Guide Modes of Operation 25 Accu-Sort Systems, Inc. Message Format Output Message Format Messages from the EZReader will include TRHDR and/or TXTRL (if they are enabled), ISO Flag byte, and requested data. The general format (with all fields) is: Response Format with Valid Tag Data Being Read TXHDR ISO Flags Data TXTRL Parameter Dependent Yes No No Yes Parameters that will cause data to be included in response from unit. TXHDRx = anything other than Null (0x00) Always sent see ISO Flag Byte below for definition Always sent TXTRLx = anything other than Null (0x00)Response Format Error Messages NOTE: Not all commands will send a error message, commands that do not will be so noted.

EZReader HF & EZTune Antenna Installation & User Guide Modes of Operation 27 Accu-Sort Systems, Inc. Hardware Trigger Mode In this mode the EZReader will operates autonomously. It will only perform Tag Read functions and send data to the Host when its Triggers are activated. The unit can use one or two triggers depending on the application. When using a single Trigger the Trigger1 input must be used and the unit will read based on a timeout set by the user. When using two triggers, Trigger1 will start the Tag Read cycle and Trigger2 will end it. In both cases the number of Tag memory blocks to be read is programmable. In Trigger Mode, all commands sent by the Host (Serial or Ethernet) are ignored by the EZReader HF, it will only send data on these ports. The only port that will respond to queries is the Setup Port. NOTE: A trigger signal must be active for a minimum of 10ms to be accepted. Trigger Mode Examples The following examples will be based upon the tag data shown in the screen capture shown below. The Tag UID is: Hex E0 07 81 26 AD 83 5D 67 (unless otherwise noted)

34 Modes of Operation EZReader HF & EZTune Antenna Installation & User Guide Accu-Sort Systems, Inc. Host Control Mode When in Host Control Mode, the EZREADER-HF will only respond to requests received on its Host serial or Ethernett ports. All activity on the Trigger inputs will be ignored. All commands regardless of which port they are received on require a Receive Header and Trailer. “STX” is the default Receiver Header and “ETX” is the default Receive Trailer. The Header and Trailer cannot be the same if changed. Messages from the EZREADER-HF will include TRHDR and/or TXTRL (if they are enabled, “STX and “ETX” are again the defaults), as well as the requested data. The general format (with all fields) is: <TXHDR><ISO Flags><data><TXTRL> Host Control Mode Response Format with Valid Tag data being Read TXHDR ISO Flags Data TXTRL Parameter Dependent Yes No No Yes Parameters that will cause data to be included in response from unit.

EZReader HF & EZTune Antenna Installation & User Guide Modes of Operation 37 Accu-Sort Systems, Inc. “I” Do an inventory of tags. Report the UIDs of tags in proximity to the antenna. Once the UID of the tag has been read, it will be in “Quiet” mode until the tag leaves the field of the antenna. Note that the bytes of the UID are output in reverse order (the same order that the EZREADER-HF expects the UID in a command). Example ASCII HEX Command STX,I,ETX 02,49,03 Response [Many NP characters] 02,67,5D,83,AD,26,81,07,E0,03 Tag will be in “Quiet” mode until the tag leaves the field of the antenna. To stop the inventory, type “E” (RXHDR and RXTRL is necessary). “L” Lock blocks. There are two available options available: • L00bb Locking a block prevents writing data to the specified block. This is a permanent irreversible change to the tag. If the lock is successful, the response will be TXHDR (if any), “YL” (Yes Lock), and TXTRL (if any). The example below is locking block 30 of a tag that is in the antenna’s field. Example ASCII HEX Command STX,L,0,0,3,0,ETX 02,4C,30,30,33,30,03 Response STX,YL,ETX 02,59,4C,5D,03 An unsuccessful lock can reply with any of the following errors: NO TAG NO ANT COLL MISREAD NL<ISO flags>

EZReader HF & EZTune Antenna Installation & User Guide Glossary 115 Accu-Sort Systems, Inc. Glossary ACK - A control character sent to acknowledge that a transmission block has been received. active/passive device - In 20mA current loop communications, a device capable of providing the current for the loop (active) and a device that draws the current from the equipment it is connected to (passive). Active tag- An RFID tag that has a transmitter to send back information, rather than reflecting back a signal from the reader, as a passive tag does. Active tags generally use a battery to transmit a signal to a reader. However, some tags can gather energy from other sources. address - A unique designation for the location of data or the identity of a smart device; allows each device on a single communications line to respond to its own message. alphanumeric - The character set which contains letters, digits and other characters such as punctuation marks. Amplitude- The maximum absolute value of a periodic curve measured along its vertical axis (the height of a wave, in layman's terms). Amplitude modulation-. Changing the amplitude of a radio wave. A higher wave is interpreted as a 1 and a normal wave is interpreted as a zero. By changing the wave, the RFID tag can communicate a string of binary digits to the reader. ANSI (American National Standards Institute) - The principle standards development group in the U.S. A non-profit, non-governmental group supported by over 1000 trade organizations, professional societies, and companies. Member body to the ISO (International Standards Organization). Antenna- An RFID tag antenna is the conductive element that enables the tag to send and receive data. Passive, low- (135 kHz) and high-frequency (13.56 MHz) tags usually have a coiled antenna that couples with the coiled antenna of the reader to form a magnetic field. UHF tag antennas can be a variety of shapes. Readers also have antennas which are used to emit radio waves. The RF energy from the reader antenna is "harvested" by the antenna and used to power up the microchip, which then changes the electrical load on the antenna to reflect back its own signals. Antenna gain- In technical terms, the gain is the ratio of the power required at the input of a loss-free reference antenna to the power supplied to the input of the given antenna to produce, in a given direction, the same field strength at the same distance. Antenna gain is usually expressed in decibels and the higher the gain the more powerful the energy output. Antennas with higher gain will be able to read tags from farther away. ASCII (American Standard Code for Information Interchange) - Pronounced ask-ee. A seven bit plus parity code established by ANSI to achieve compatibility between data services. asynchronous transmission - Transmission in which the time intervals between transmitted characters may be of unequal length. Transmission is controlled by start and stop bits at the beginning and end of each character. baud rate - A unit used to measure communications speed or data transfer rate; represents the number of discrete conditions or events per second. BCC (Block Check Character) - Used to check transmission accuracy, a character transmitted by the sender after each message block and compared with a block check character computed by the receiver. bed width - The width of the conveyor bed measured in inches. BEL - A control character that is used when there is a need to call for attention; it may control alarm or attention devices. belt width - The width of the conveyor belt measured in inches.

If used there is not enough clearance for a standard front or back read. BPS (Bits per Second) - Unit of data transmission rate. See baud rate. bridge - An interface between links in a communication network that routes messages from one link to another when a station on one link addresses a message to a station on another link. buffer - A temporary storage device used to compensate for a difference in data rate and data flow between two devices (typically M). bus - An internal pathway along which electronic signals travel between the components of an electronic device. button - A graphic user interface component that allows users to select a given software function. Instead of physically pressing a button, the user simply clicks on the desired button to access a menu, tab screen, or function. byte - A binary element string functioning as a unit, usually shorter than a computer "word." Eight-bit bytes are most common. Also called a "character." capture count - The number of consecutive identical valid decodes that result in a valid read. cart - A signal, typically provided by a photoeye or proximity switch, that informs the scan head of the presence of an object within its reading zone. Also called trigger. communications protocol - The rules governing exchange of information between devices connected together on the same communications line. configuration - The arrangement and interconnection of hardware components within a system, and the hardware (switch and jumper) and software selections that determine the operating characteristics of the system. configuration file - The set of attributes which belongs to and defines the operation of a single physical device. conveyor speed - The speed that the conveyor is moving measured in feet per minute. Conveyor speed directly impacts the time that the code is in front of the scanner; therefore, it affects the number of reads that are possible. CR (Carriage Return) - An ASCII or EBCDIC control character that moves the cursor or print mechanism to the left margin. CTS (Clear to Send) - The modem interface signal that indicates to the DTE device to begin transmission. current loop - Method of interconnecting terminals and transmitting signals, whereby a mark (binary 1) is represented by current on the line and a space (binary 0) is represented by the absence of current. decoder - As part of an reading system, the electronic package which receives the signals from the reader, performs the algorithm to interpret the signals into meaningful data and provides the interface to other devices. decoder logic - The electronic package that receives signals from the reader, interprets the signals into useful data, and provides the interface to other devices. default(s) - Original parameters as programmed by Accu-Sort at the factory. depth of field - The distance between the maximum and minimum plane in which a tag can be read. DIP switches - Switches that are the approximate size of an integrated circuit. downloading - The process of sending configuration parameters, operating software or related data from a central source to remote stations.

High-frequency RFID tags typically operate at 13.56 MHz and can be read from less than 3 feet away and transmit data faster than low-frequency tags. But they consume more power than low-frequency tags. host - 1) A central controlling computer in a network system. 2) Any device on a network system that provides a controlling function to another device on the network. 3) Any intelligent device for which another device is providing a communication interface to a network. induct photoeye - The cart cycle begins when the start of cart photoeye is blocked and continues until the cart photoeye is unblocked. Blocking the induct photoeye causes relay decisions and data communication. For this placement the distance between the cart and induct photoeyes must be less than the minimum box size plus the minimum box spacing. Inlay- An RFID microchip attached to an antenna and mounted on a substrate. Inlays are essentially unfinished RFID labels. input/output modules - Since many readers are operating in environments that have electrical noise problems, it is helpful to have equipment electrically isolated from other equipment. The standard method for isolating inputs and outputs is through the use of optically isolated input/output modules. These flexible modules allow the reader to control high voltage outputs that are susceptible to noise. Since they are isolated from each other the noise is not picked up in the scanner. The modules come in both input and output versions. The output versions are controlled by a 5VDC input. The output of the modules can range from 24VAC - 140VAC or 3VDC - 200VDC. Foreign voltage ranges are available. The maximum current that the modules can supply is limited by the output voltage and the module type. The input versions are controlled by either a DC or AC input ranging from 3VDC - 32VDC or 90VAC - 140VAC. Foreign voltage ranges are available. The output of the modules is a 5VDC level. The maximum current is limited by the input modules. These output modules are commonly used to control diverters, alarms, external relays, etc. The input modules can be used for photoeye inputs. interface - A shared boundary defined by common physical interconnection characteristics, signal characteristics and meanings of interchanged signals. I/O - The abbreviation for input/output. The keyboard and a printer, are examples of I/O devices. I/O activity is different from computational activity.

When data is transmitted serially from a communications port, the information is transferred between the two devices one data bit at a time. The data flow can follow one of three different communications modes: simplex, half duplex, or full duplex. Each character of data within the data flow is transported in a binary bit frame called the asynchronous data frame. The start bit begins each frame. A low voltage signal on the data communications line marks the beginning of the start bit, at which point the receiving device begins looking for binary zeros and ones (0s and 1s). The following five to eight data bits (the number depends on the format used) comprise the binary character. For error detection, an optional parity bit can define whether the total number of zeros or ones was even or odd.
EZReader HF & EZTune Antenna Installation & User Guide Glossary 123 Accu-Sort Systems, Inc. There are five different parity selections: • ODD - last data bit is a logical 0 if the total number of logical 1s in the first seven data bits is odd. • EVEN - last data bit is a logical 0 if the total number of logical 1s in the first seven data bits is even. • MARK - last data bit is always a logical 1 (i.e.: high/mark). • SPACE> - last data bit is always a logical 0 (i.e.: low/space). • OFF (NONE) - last data bit is not present. The method used to catch errors by using parity bits is as follows: When the transmitter frames a character, it tallies the number of 0s and 1s within the frame and attaches a parity bit. (The parity bit varies according to whether the total is even or odd.) The receiving end then counts the 0s and 1s and compares the total to the odd or even recorded by the parity bit. If a discrepancy is noticed by the receiving end, it can flag the error and request a retransmission of the data. A stop bit is used to signal the end of the character. Stop bits are typically one or two bits in length. The slower the transmission speed, the more stop bits required for recognition of the end of the data frame. In addition to the direction of data flow and the data framing, there are other considerations to insure uniform transmissions. Certain operating parameters must be followed to prevent the loss of valuable data. The first consideration is the speed of transmission, known as baud rate. Serial data transmission is measured in bits per second (BPS). The baud rate selections available for the 6000 are: 110, 300, 1200, 2400, 4800, 9600 and 19200. To enable two devices to interact, they must both be transmitting/receiving data at the same baud rate. If it is not possible to do this, there must be a buffer (typically additional storage memory) that accommodates the differences in communications speed. Many serial communications links also use a flow control system to handle data transmission in addition to memory buffers. X-ON/X-OFF Protocol A common type of flow control is the X-ON/X-OFF protocol. When a receive buffer nears its memory capacity, the receiving device sends an ASCII X-OFF signal to the transmitting device, telling it to stop sending data. When the memory buffer has enough space to handle more data, the X-ON signal is sent to the transmitting device, telling it to start sending data again. ACK/NAK Protocol device transmits a message to the host, the host responds with either an ACK (06H) or a NAK (15H). If the host transmits an ACK to the device, the device deletes its transmit message and the communication sequence is complete. If the host transmits a NAK, the device will retransmit. The device resends data a maximum of three times. Optionally this may be changed to 1, 2, 3, or infinite retransmits by the user. If the device receives a fourth NAK, it will delete the data in its transmit buffer and display "MAX REXMITS." A transmitting device ignores ACK and NAK characters received during data transmission. If, for example, a device receives a NAK during a data transmission, it will not resend the data at the completion of the transmission. The device also has a retransmit timer. This timer is activated each time the device transmits data to the host. If the timer runs for two seconds (this is also changeable) and the device does not receive an ACK or NAK from the host, a timeout occurs and the device retransmits its data. Each time the device retransmits because of a timeout, it treats the timeout the same as receiving a NAK from the host computer. If the device does not receive an ACK before the end of the fourth timeout, it will delete the data in its transmit buffer and display "MAX REXMITS."
124 Glossary EZReader HF & EZTune Antenna Installation & User Guide Accu-Sort Systems, Inc. The device deletes data in its transmit buffer and displays the error message when any combination of four timeouts and NAKs from the host occurs. When the device receives a message from the host, it calculates the BCC for the message and compares the calculated BCC to the received BCC. If the two values match, the device transmits an ACK, ending the communication. If the values do not match, the device transmits a NAK to the host and waits for the host to retransmit the message. The host, like the device, should retransmit a maximum of three times. The sequence number starts at zero (30H) and is incremented each time a device transmits a new message. When the sequence number reaches nine (39H), it wraps around to one (31H). If the sequence number skips a number, the receiving device knows that a message was lost. If the same sequence number is received on two sequential messages, the second message is responded to with an ACK or NAK (as appropriate) and ignored. shielding - Protective covering that eliminates electromagnetic and radio frequency interference. side read - The scanner/antenna is mounted to read the side of a box as it passes by the head. signal - An impulse or fluctuating electrical quantity (i.e.: a voltage or current) the variations of which represent changes in information.

The charges are then shifted along the second set of areas in a bucket brigade fashion with the last areas charge being shifted off the sensor entirely (for further processing). This holding area does not have to all be shifted out of a single port the holding line may be broken into several sections, each with its own exit from the sensor. Each exit is called a tap or channel. Generally, the more taps the more quickly the image data may be shifted
