These limits are designed to providereasonable protection against harmful interference in a residential installation. Thisequipment generates, uses, and can radiate radio frequency energy and, if not installedand used in accordance with the instructions, may cause harmful interference to radiocommunications. However, there is no guarantee that interference will not occur in aparticular installation. If this equipment does cause harmful interference to radio ortelevision reception, which can be determined by turning the equipment off and on, theuser is encouraged to try to correct the interference by one or more of the followingmeasures:• Reorient or relocate the receiving antenna.• Increase the separation between the equipment and receiver.• Connect the equipment into an outlet on a circuit different from that to which thereceiver is connected.• Consult the dealer or an experienced radio/TV technician for help.This device complies with part 15 of the FCC Rules. Operation is subject to the followingtwo conditions:(1) This device may not cause harmful interference, and(2) This device must accept any interference received, including interference thatmay cause undesired operation.
CDH CommunicationsIntroductionThe CDH Communications 9Xtreme is a frequency hopping data transceiver radiodesigned for integration with other products. The 9Xtreme operates within the 900 MHzISM Band under Part 15 of the FCC Rules and Regulations.The 9Xtreme allows OEMs to integrate the radio into their own systems. When installedusing a CDH Communications approved antenna, the system integrator needs to makesure the 9Xtreme’s FCC label, or a copy of that FCC label, is clearly visible on theoutside of the integrated product.Caution: If this radio is integrated into another product, the system integrator isresponsible for complying with the external labeling requirements as directed in the FCCRules and Regulations Part 15.19. The system integrator may only use antennas thathave been tested and approved with this radio to maintain the FCC approval. If a systemintegrator uses a non-approved antenna they are responsible for obtaining their ownFCC certification. The radio also requires +5V source voltage. Any voltage higher than5.5V will damage the radio.Approved AntennasMfr Model Freq Gain Type Connector DimensionsAstron AXQ900PTL 902-928 2dBi Omni MMCX 3”Astron AXH900 RPSMA R 902-928 2dBi Omni ReversePolarity SMA 6.5”CDH 900CDAN 902-928 2dBi Omni Integrated 3”In order to comply with the FCC RF exposure requirements the Data Radio must beinstalled with the antennas listed above and a minimum separation distance of 20 cmmust be maintained from the antenna to any near by persons.The Radio uses an asynchronous serial interface with a start bit, stop bit and eight (8)data bits at TTL levels for communicating with the host system. Using an RS232 driverchip (such as a Maxim MAX232) the Radio can communicate directly to a standardSerial Communications Port on a PC. See the section titled Demo Kit Instructions for atutorial to help get started using the 9Xtreme Radio.9Xtreme Features:• Frequency Hopping Spread Spectrum (FHSS) technology• Secure over the air data encryption• Resistant to noise and interference.• 130mW transmit power• 25 mile (40 Kilometer) effective range (line of sight)
CDH Communications• Broadcast (promiscuous) networking protocol – data sent to the serial port on oneradio will be presented out of the serial port on all other radios that are within rangeand have the same group code.ConnectionsThe Data Radio is connected to a host device using the 11 pin and the 4 pin berg headers.These connections provide the radio with the required DC power source (+5V) and allowthe Data Radio to be programmed, configured and provide the I/O lines for theasynchronous line level (TTL) RS-232 connection.J1 PIN DESCRIPTIONSJ1-1 CTS Clear to send flow control (output)J1-2 INT1 Interupt line to radio processor (input, not currentlyimplemented)J1-3 TX Asyncronous data output (data going from radio to user)J1-4 RX Asyncronous data input (data going from user to radio)J1-5 RTS Ready to send flow control (input, not currently implemented)J1-6 *RESET Reset line to radio processor (pull low to reset radio processor)J1-7 MOSI SPI data in (input, not currently implemented)J1-8 MISO SPI data out (output, not currently implemented)J1-9 SCK SPI data clock (input/output, not currently implemented)J1-10 Power +5 volts DC.

CDH CommunicationsUsing the 9Xtream Demo KitIntroduction:Use this demo kit to experience the power and sensitivity ofthe CDH 9Xtream radio. This radio transmits data at 19200bits per second in the license-free 900MHz ISM band. See howsimple it is to communicate with the radio using asynchronousserial communications by following the instructions below.Contents:29Xtream Frequency Hopping 900MHz 19200bpsradios2Demo Boards2Battery clips with 9-volt battery2 DB-9 connecting cables2DB-25 to DB-9 converters13.5" floppy disk containing file RAT.TXTRequirements:2 computers with an available comm port and Windows 95/98 orNT.Instructions:1. Assemble and Connect Demo Boards to computers.a. Connect the radios to the Demo Boards by fitting the 4and 11-pin connectors into their respective femaleheaders.b. Attach the male sides of one of the DB-9 ConnectingCables to the female DB-9 jacks on the Demo Boards.c. Attach the female side of a DB-9 connecting cable to anavailable comm port on the back of Computer 1.Connect Radio 2 to Computer 2 in the same fashion.d. Plug Battery clips into the Demo Boards. The greenLEDs on the Demo Boards will illuminate to show theboards are powered.e. Refer to figure 1 for completed assembly.2. Run and configure HyperTrm.exe on both computersa. Open the folder on the Start Menu found underPrograms -> Accessories -> Communications ->HyperTerminal.b. Double-click on the application HyperTrm.exe andchoose a name and an icon for the new connection inthe Connection Description dialogue box.c. In the Connect To dialogue box on each computer,select Connect using: Direct to Com1 or Direct toCom2 to correspond with the comm port used on therespective computers (see figure 2) . Click OK.d.

CDH Communicationse. Both computers are now set up and ready to communicate.3. Test Connectiona. Place cursor in HyperTerminal window of Computer 1 and type a message. Notice thattext appears only in the window of Computer 2 and text typed on Computer 2 appearsonly on Computer 1. This text is being transferred over the air by the CDH 9Xtreamradios.b. Transfer the file RAT.TXT i. On Computer 1: Select Transfer menu -> Send File(or try right-clicking in theHyperTerminal window). Insert the disk intothe A: drive and enter Filename:A:\RAT.TXT Select Protocol: Ymodem (Seefigure 4). Press Send. ii. On Computer 2: Select Transfer menu ->Receive File. Select a folder in which toplace the file and select Protocol: Ymodem(see figure 5). Press Receive. iii. The file will begin to transfer and any errorsor retries will be accounted for. Touch theantennas and move the radios around tonotice that errors or retries do occur undercertain circumstances. iv. When the transfer completes, openRAT.TXT on Computer 2 and observe thepattern of text, it will be easy to see if anycharacters were lost or corrupted. v. Any file can be transferred this way. Useeither Xmodem or Ymodem protocol. Bothcomputers must have the same settings.c. Try range testing by distancing the two computers from each other. The radios can sendand receive data over 20 miles line of sight.4. Problems (Trouble Shooting)a. Can’t find the HyperTerminal on your computer? i. Search your hard drive for HyperTrm.exe ii. Download a free version from http://www.hilgraeve.comb. Power LED doesn’t illuminate when battery clip is attached? i. Replace the battery.c. Cannot connect to the comm port or communication not working? i. Try selecting another comm port by selecting Properties under the File menu. ii. If necessary test the comm ports with a null modem cable (cross RX and TX)between the two computers to verify operation of comm ports.d. Some characters come through but not all? i. Verify that both comm ports are set to 19200 bits per second.Figure 4 – Send File Dialogue BoxFigure 5 – Receive File Dialogue Box
