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. No special characters, hardware control lines, or timing is
required to operate the RV-D80-EB/RV-M80-EB modem.
There is also a “Command Mode” used to program and configure the M8. In
the Command Mode, the RV-D80-EB/RV-M80-EB modem accepts
commands via the serial port TxD pin. The commands can be used to
change certain internal parameters of the RV-D80-EB/RV-M80-EB modem
as well as to read-out the current configuration and diagnostic statistics.
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
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. If either pause is missing, the modem will not enter the
command mode.
Using serial communications software such as HypterTerminal, send the 3-
character command sequence “+++” while observing times of silence before
[BT (Silence Before Sequence) Command] and after [AT (Silence After
Sequence) Command] the command characters. The default BT and AT
times are 500mS.
The default sequence for entering into AT Command Mode:
1. No characters sent for ½ a second.
2. Input three (3) plus characters (“+++”) within ½ of a
second.
3. No characters sent for ½ a second.
When the RV-D80-E/RV-M80-EB modem first enters the Command Mode, it
sends the phrase
Raveon RV-D80-E/RV-M80-EB (transceiver version)
or
Raveon M8R (receive only version)
out of its serial port, and then an “OK” sequence. The “OK” sequence is a
sequence of 4 characters:

12 Raveon Technologies Corp.
An “O”, “K”, <CR>, and <LF> characters
(<CR> = ASCII 0D, <LF> = 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. For Example, to set the
address of the RV-D80-EB/RV-M80-EB modem to 1234, enter the following
command:
ATDT 1234 <CR>
Once a Parameter is changed, the modem will begin using the new
parameter and the new parameter is saved to non-volatile.
4.4. Reading a Parameter
To read the value of a particular setting, issue the command, with no
parameter. The modem will return the value followed by an “OK”. The
modem’s OK response is:
The value in ASCII decimal format.
A <CR> <LF> (<CD> = ASCII 0D, <LF> = ASCII 0A).
An “O”, “K”, <CR>, and <LF> sequence.
For example, if the user enters the command to read the M8’s modem
address and its address was 1234, the user would issue the following
command:
ATDT<cr>
and the modem will respond with:
1234 <CR> <LF>OK <CR> <LF>
To get on-line help with a command, enter the command and put a question
mark in for the parameter. For example, to see what the ATDT command is
for, type:
ATDT ?
The modem will respond by listing a brief description of the command. To
see a list of all commands, type HELP.
Many commands support the “MIN” and “MAX” parameters to read the
minimum and maximum allowable settings. For example, type ATJF MAX to
find the maximum value the CTS negation threshold may be set to.
4.5. CONFIG Button
If certain parameters within the modem are modified in a manor that causes
the modem to cease functioning or if the user cannot enter the command
mode via the “+++” 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

13 Raveon Technologies Corp.
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. Serial port on the front of the unit in RS232 mode, 9600bps, N/8/1.
Even though the serial baud rate reverts to 9600 baud when the CONFIG
button is pressed and the IO port is RS232, it will revert back to the settings
programmed into the RV-D80-EB/RV-M80-EB modem once the Command
Mode is exited.
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.
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. Changes will not automatically be saved. This
time-out duration may be set with the ATCT command.

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. To program a channel, perform the following steps.
1. Change to the channel you wish to program, using the ATFC command.
ATFC x tt rr c ab
where x is the channel number,
tt is the TX frequency in HZ or MHz,
rr is the Rx frequency in Hz or MHz
cis 4 for control channel, 0 for non-control channels,
ab are the over-the air modulation options.
a. ais the bit rate index corresponding to the over-the-air bit rate to use:
0=4800 2L, 5=9600 2L, 6=19200 4L, 8=9600 4L, 0=4800 2L,
b. bis the channel bandwidth. 0=12.5kHz, 1=25kHz.
2. For Example, enter ATFC 3 217.425 219.425 4 00 to set the channel 3
TX frequency to 217.425MHz and RX frequency to 219.425MHz, 4800 bps,
two-level modulation, narrow band channel.
3. Review the frequency setting with the ATFC x where x is the channel number
to display.
4. To display all channel’s, use the ATFC ALL command.

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/RV-
M80-EB to stop working on your network.

On RV-D80-EB/RV-M80-EB , the periodic reporting must be enabled. This
command is set at the factory to enable GPS periodic reporting.
GXF 1 1 Enable periodic GPS tracking reporting
7.Data Transmission
To transmit data, send one or more bytes of data into the serial port of the
modem. When a full packet of data has been collected into the internal buffer of
the modem, or when there is a pause in the data, the modem will automatically
key its transmitter, and send the data over the air if the modem is within range of
a base station.
Serial Port Baud Rate
While the RV-D80-EB/RV-M80-EB modem is transmitting and receiving data on
the DART network, the user may continue to send more data into the RV-D80-
E/RV-M80-EB .Because the buffers in the RV-D80-EB/RV-M80-EB are full-
duplex, the serial port data rate and the over-the-air data rates are independent.
The serial port baud-rates may be set slow to accommodate legacy equipment,
or set at high-speed to minimize latency.
