Page 4: General Information About The Rv-M8
1. General Information about the RV-M8 1.1. Congratulations! Congratulations on your purchase of a TK8 OEM radio modem – the most advanced radio modem of its kind available today. Please take a few minutes to read this manual carefully. The information presented here will allow you to derive maximum performance from your radio modem. -
Page 5: Oem Use
Human body Exposure: This equipment is approved only for mobile and base station transmitting devices, separation distances of 36 centimeters or more for antennas with gains of 0 dBi or less or (ii) 1 meters or more for antennas with gains 0 to 6 dBi should be maintained between the antenna of this device and nearby persons during operation. -

2.2. Firmware Updating The TK8 is a software based radio and modem. There are times an existing unit needs to get updated with a new feature, and this can often be done by loading the new firmware Company Confidential... - Page 7 In firmware program called the “Boot Loader” is permanently installed inside the TK8’s microcontroller. During power up, it checks to see if the user wants to update the application program in the microcontroller. The STAT1 pin is used to trigger the Boot Loader. See application note AN186 for details on how to boat load new firmware into the TK8.

4. Electrical Inputs and Outputs 4.1. LEDs Status LED (TX) This LED blinks indicates the status of the device as follows: Color Power LED (PWR) This LED does a short blink, once every two seconds, indicating to the user that the power to the modem is ON and the modem is working. When the modem is in the command mode, this LED will blink on and off, once per second. -
Page 11: Heatsinking
4.3. Heatsinking The TK8 operates at up to 10% transmit duty cycle at ambient temperatures up to 50°C. For duty cycles up to 50%, the module requires additional heat sinking. If an external heat sink presses against the “GND PAD” are of the PCB, the RF power transistor will run cooler, and allow higher duty cycles. -
Page 12: User Serial Port Commands
Command Mode, the TK8 modem accepts commands via the serial port TxD pin. The commands can be used to change certain internal parameters of the TK8 modem as well as to read-out the current configuration and diagnostic statistics. 5.2. Command Mode The TK8 modem may be put into a “Command Mode”, by entering a... -
Page 13: Setting A Parameter
“+++” method described above, there is a small push button internal to the TK8 modem to assist in this case. This CONFIG button may be pressed at any time, and forces the modem into a known operational state. -
Page 14: Exiting The Command Mode
1. ATCN Issuing the ATCN. The TK8 radio will exit the command mode, and begin normal operation. 2. EXIT Issuing the EXIT. The TK8 radio will exit the command mode, and begin normal operation. 3. Time Out. After a pre-set amount of time (60 seconds is the factory default time), the modem will automatically exit the Command Mode, and continue normal operation. -

TK8 radio network. 10.2. Reading the Diagnostic Information TK8 diagnostic information is read using AT commands, while the unit is in the Command Mode. Refer to the section “User Serial Port Commands” to learn how to put the TK8 modem into the Command Mode. -
Page 23: Tune-Up And Alignment
11. Tune-up and Alignment The TK8 modem has been factory calibrated, in should not require any re- calibration when installed, or when changing frequency or channel. Unless the user is trained in radio test and calibration, the values stored in the R registers should not be modified. -

2. Transmit random data on the center of the band, using the ATTD 1 command. This command will cause the TK8 to automatically key up, and send random data for one minute. 3. Verify the DC center of the demodulated data is stable. The random data should be randomly timed 1s and 0s, and have little to no AC component on them. - Page 26 Mode 3 - CD OFF In this mode, the CD pin is always negated.
