Raveon accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using Viper SC, or for the failure of Viper SC to transmit or receive such data.
Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. Company Confidential 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-M80-EA2 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-M80-EA2 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-M80-EA2’s microcontroller.

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. Company Confidential Raveon Technologies Corp.
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 Company Confidential Raveon Technologies Corp.
4.2. Command Mode The RV-M80-EA2 modem may be put into a “Command Mode”, by entering a sequence of three plus characters (+++). To keep the RV-M80-EA2 modem from unintentionally entering the Command Mode because of the +++ pattern occurring in a stream of data entering the modem, there must be a pause in the data stream before the +++ as well as a pause after the +++ is sent.
4.3. Setting a Parameter To set a parameter in the RV-M80-EA2 modem, enter the Command Mode as described above. Then enter the proper AT command, a space, the parameter, and then a carriage return. For Example, to set the address of the RV-M80-EA2 modem to 1234, enter the following command: ATDT 1234 <CR>...
4.6. Exiting the Command Mode There are three ways to exit the command mode. They are: 1. ATCN Issuing the ATCN. The RV-M80-EA2 radio will exit the command mode, and begin normal operation. 2. EXIT Issuing the EXIT. The RV-M80-EA2 radio will exit the command mode, and begin normal operation.
5. Command Mode Commands 5.1. General Common Commands These commands apply to the general configuration of the RV-M80-EA2, and are applicable in both the data modem mode and paging mode. Factory Command Command Description Parameters Default Silence AFTER Sequence - Sets period of silence after the Range:0 –...

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-M80-EA2 default. 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. If the “Radio Type” is changed, these will need to be re-calibrated. 5.2. Data Modem Mode Related Commands These commands apply to the operation of the RV-M80-EA2 when it is in the data modem communication mode. Factory Command...

Ch 1 ....462.2125 MHz 6. Programming Channels and Frequencies The RV-M80-EA2 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.
Loads the channel banks with default channels ATIO 5 Digital I/O mode HWMODE 0 Hardware mode 0 Once the RV-M80-EA2 is ready to be used on a DART network, make sure all of these settings are set. ATMT 5 Hyper/DART modem type SID xx Set the system ID On RV-M80-EA2, the periodic reporting must be enabled.

RV-M80-EA2 radio network. 9.2. Reading the Diagnostic Information RV-M80-EA2 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-M80-EA2 modem into the Command Mode.
10. Tune-up and Alignment The RV-M80-EA2 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.
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-M80-EA2 to automatically key up, and send random data for one minute.
