2. Overview The R V - D 8 0 - E B / R V - M 8 0 - E DART compliant Data radio modem is capable of highspeed narrow-band data communications. It contains a receiver, a transmitter, and modem, creating an easy-to-use transparent data radio link. The built-in DART protocol is compatible with Raveon’s DART data radio protocol (Dynamic Automatic Radio Transmission). (www.raveon.com/DART ) This radio modem is not compatible with Raveon’s M7 series of data radio modems.
2.2. Firmware Updating The RV-D80-EB/RV-M80-EB 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 into the older radio modem. In firmware program called the “Boot Loader” is permanently installed inside the RV-D80-EB/RV-M80-EB ’s microcontroller. During power up, it checks to see if the user wants to update the application program in the microcontroller. 2.3.

3. Electrical Inputs and Outputs 3.1. RS-232/EIA232 Serial I/O Connector The RS-232 9-pin serial I/O connector is a female 9-pin D-subminiature connector having the following pins configuration. It is pinned out so that it may be plugged directly into a computer or PC’s 9-pin COM port.
3.2. GPS (-GX option) GPS receiver for position tracking utilizes a MAX-7 GPS receiver. MAX 7 Product description The MAX-7 series is the newest family of standalone GPS/GNSS modules from u-blox. With the exceptional performance of the u-blox 7 multi-GNSS (GPS, GLONASS, Galileo, QZSS and SBAS) engine, the MAX-7 series delivers high sensitivity and minimal acquisition times in the ultra compact MAX form factor. The MAX-7 series provides maximum sensitivity while maintaining low system power.
4. User Serial Port Commands 4.1. Overview The serial portion the RF modem is used to send and receive data over the air, as well as to configure the RF modem. In normal operation, the user sends data into the TXD pin of the IO connector, and this data is transmitted over the air. Received data from another RF modem is output to the user via the RXD pin of the IO connector. This is the default operating condition of the RF modem.
An “O”, “K”, , and characters ( = ASCII 0D, = ASCII 0A) 4.3. Setting a Parameter To set a parameter in the RV-D80-EB/RV-M80-EB modem, enter the Command Mode as described above. Then enter the proper AT command, a space, the parameter, and then a carriage return.
CONFIG button may be pressed at any time, and forces the modem into a known operational state. The CONFIG button is located inside the modem. Remove the rear cover, exposing the two circuit boards. The button is in the front edge of the radio module’s circuit board. The default settings that the modem will revert to when the CONFIG button is pressed are: 1. Serial port 9600 baud, 8 data bits 1 stop, no parity 2. ATCT setting set to 60000 (60 second time-out) 3.
5. Command Mode Commands 5.1. General Common Commands These commands apply to the general configuration of the RV-D80EB/RV-M80-EB , and are applicable in both the data modem mode and paging mode. Command Command Description Parameters Factory Default Silence AFTER Sequence - Sets period of silence after the command sequence characters in mS. Range:0 – 1000 (mS) ATBD Baud Rate – Sets serial com port baud rate (bps). Type the range index (0-7) or the actual desired baud rate.
ATFX TX and RX Frequency – Program the receive and transmit frequency for this channel. Enter in Hz or MHz. Same as issuing an ATFR and an ATFT command. The frequency will automatically be saved in non-volatile memory (flash) for this current channel number. ATHP Channel Number – Select current radio channel number. The channel number is stored in EEPROM memory. Range: 1 - 6 ATIC Read Current Draw Read the current draw in mA. Accuracy is within 20% of actual current draw.
AT&F BAND Restore Factory – Restore the factory default values. This command will not erase the calibration values. After this command executes, the modem will still be in the CONFIG mode. Read the Band – Reads the frequency band of the radio. First parameter is the text version (UA, UC, VC, …), second parameter is the lower limit, and the third parameter is the upper limit in MHz. Use to read the band that the radio is tuned to cover. CONFIG Display configuration. Displays most all variables.
SCB SYSKEY NETKEY SID RDP TABLE Set Channel Bank. Configure a channel bank or read a channel bank. SCB B Y C P B: bank number 1-10, Y:Entry Number C:Channel Number a(optional): P is optional. Set to “C” if this entry is a control channel. SCB X to read and display a bank’s settings. SCB X ERASE will erase all entries in bank X. SCB X Y DELETE will delete channel Y from bank X. SET the encryption key. Set the SYSTEM encryption key. This is an ASCII hex representation of the 128 bit key.
5.6. Factory Default Settings (DART Data Transceiver) For the UHF RV-D80-E/RV-M80-EB , model RV-D80-E/RV-M80-EB -UC, the main factory defaults are: General Settings Primary Protocol: (ATMT 0)............................... Packet Data WMX (WMX 0) .................................................. OFF Data Modem Settings: Over-the-air data modem baud rate: ................. 4800 baud, 2-level Serial port .......................................................... 9600baud, N/8/1 Hardware flow control .......
5. Some data rates are not suitable for use on certain channel bandwidths. For example, 19200 4-level modulation will not work on a 12.5kHz narrow-band radio channel. 6.1. Initializing a new RV-D80-EB/RV-M80-EB to factory defaults Warning, this will erase all parameters, and may cause your RV-D80-EB/RVM80-EB to stop working on your network.
8. Debug Related Commands Bench Testing (Must be in command mode to test. Enter +++ at the keyboard to put unit into config/test mode.) ATTD x Various transmit test routines. 0 = Go back to normal mode. Stops the test. 1 = Random data transmit. 3 = Force PLL to fast lock mode 4 = Transmit all 0s 5 = Transmit all 1s 7 = Transmit CW on center of channel 8 = Transmit preamble (101010 pattern) ML x Debug Message Level. By default and at power on, this level is set to 0 (no debug messages).
9. Diagnostic Provisions 9.1. Overview of Diagnostics Internal to the RV-D80-EB/RV-M80-EB radio modem, is a powerful 32-bit microprocessor. Along with handing all aspects of radio modulation and demodulation, the microprocessor also maintains an extensive array of diagnostic information. This section details the diagnostic information available, and describes how to us the information to optimize or troubleshoot a RV-D80-EB/RV-M80-EB radio network. 9.2.
10. Tune-up and Alignment The RV-D80-EB/RV-M80-EB 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. Radio calibration and alignment is performed using the ATRx commands. Improper adjustment of the radio calibration (R0-R9 and RA registers), can result in failure of the radio modem.
10.2. Calibration Commands The following AT commands are used to calibrate the M8. Do not ever change these unless you have been factory trained to do so. AT Command Description Command R0 R1 Symbol Peak Deviation – Set the peak FM deviation of the transmit symbols. Note: This can be a negative number to invert the modulation. Select CD pin output signal – CD pin may be RF carrier detect, or modem data detect, off, on, or RX data framing, or on-line status.
10.4. TX Deviation 1. Switch to channel 1. 2. Key the transmitter into a 50 ohm load using the ATTD 3 command. The unit will now transmit, and send a digital 0 continuously. This should be +2.0kHz in frequency for narrow-band radios (12.5kHz spaced channels) and +4.0kHz for wide-band (25kHz channels). 3. Adjust the deviation register setting so that the frequency deviation is correct. The deviation is set with a digital adjustment. Use the ATR0 command to read or set the deviation level. 10.5.
