1.2. NOTICE There are no user-serviceable points inside this transceiver. All service work must be referred to your Authorized Service Center or Raveon Technologies Service Department. IMPORTANT NOTICE ! Because of the nature of wireless communication, transmission and reception of data can never be guaranteed.
1.6. Transmitter Output Power: Warning Adjusting the transmitter output power may jeopardize the granted licenses and authority to use this radio. This radio is manufactured fully calibrated to within federal limits. Raveon Technologies Corp.
The command-line interface is similar to Raveon’s other data radio products, and configuring the mode is very easy. The RV-D80-EB/RV-M80-EB is an easy to use and its re-programmability makes it extremely versatile. Most parameters within the modem may be re-configured to optimize it for specialized operations, extended range, or higher data throughput.
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”...

Clear to send send. If the M7 cannot accept more data, it will negate this signal (set to a In/o DC power (not User may supply the DC power to the Power Ring signal) modem on this pin. Raveon Technologies Corp.
This makes it perfectly suited for industrial and mass-market end products with strict size and cost requirements. The DDC (I2C compliant) interface provides connectivity and enables synergies with u-blox SARA, LEON and LISA wireless modules. u-blox 7 modules use GPS/GNSS chips qualified according to AEC-Q100 Raveon Technologies Corp.
4.2. Command Mode The RV-D80-EB/RV-M80-EB modem may be put into a “Command Mode”, by entering a sequence of three plus characters (+++). To keep the RV-D80- EB/RV-M80-EB modem from unintentionally entering the Command Mode...
“+++” method described above, there is a small push button internal to the RV-D80-EB/RV-M80-EB modem to assist in this case. This Raveon Technologies Corp.
4.6. Exiting the Command Mode There are three ways to exit the command mode. They are: 1. ATCN Issuing the ATCN. The RV-D80-EB/RV-M80-EB radio will exit the command mode, and begin normal operation. 2. EXIT Issuing the EXIT. The RV-D80-EB/RV-M80-EB radio will exit the command mode, and begin normal operation.

When data is entering the serial port, and this Range: 1 - 999 20mS is the ATR3 amo0unt of time passes with no more data, the RV-D80-EB/RV- default. M80-EB will begin to transmit the data over the air. Range: -500 to Frequency Offset.
** indicates values that are calibrated in the factory and are unit-specific. 5.3. DART Related Commands The following commands are specific to the operation of the RV-D80-EB and RV-M80-EB when used on a DART Dynamic Automatic Radio Transmission system. DART features are enabled when the Modem type (ATMT) parameter is set to DART, which is type 5.
The following commands may be helpful in diagnosing communication problems or system performance. Display/Set Feature GXF X Y Display, set, or disable various GPS features. 1-10 X is numeric feature code: 1 = Periodic GPS position reporting. Y= 0 for off, 1 for on. Raveon Technologies Corp.
Ch 1 ....462.2125 MHz 6. Programming Channels and Frequencies The RV-D80-EB/RV-M80-EB modem has memory for up to 100 channels. A channel is a pair of frequencies, one for transmit and one for receive. They may be different or they may be the same. You may program any valid frequency into any channel number.
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/RV- M80-EB to stop working on your network. AT&F...

RV-D80-EB/RV-M80-EB 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 RV-D80-EB/RV-M80-EB modem into the Command Mode. To see a general overview of how the modem has been operating, us the ATST command (status request command), without any parameter.
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.
3. Read the frequency offset with the ATR8 command. 4. Adjust the frequency to the center of the channel with the ATR8 command. You can use the “U” key and the “D” key to change the settings up and down one value in real time. Raveon Technologies Corp.
FM signal must be greater than 10Hz to 5kHz without any de-emphasis. 2. Transmit random data on the center of the band, using the ATTD 1 command. This command will cause the RV-D80-EB/RV-M80-EB to automatically key up, and send random data for one minute.
