Additional Personal-Locator Related Commands
The following commands are unique to the –PL version of the RV-M7. When you
execute any of these commands, the new parameter is automatically stored in
EEPROM. Unlike the Modem Commands in the table above, you do not need to
issue the "ATSV" command to save –PL related parameters listed in the table
below. The parameters in all GPS commands listed below are automatically saved
to EEPROM when they are executed.

The ALERT x command may be used to read the alert
condition and control it alert feature via the serial port,
ALERT
or controlled over-the air using RPR commands.
0=none, 1= normal, 2=critical alert, 3=acknowledged.
Transmit Channel Access Method. Enables TDMA
ATTX
operation. 0=standard carrier-sense. 1=TDMA.
Singe-hop repeat. Only applicable if repeater function
is enabled. (ATXR = 1)
ATHX
programmed . 1 = will not repeat any packet that has
already been repeated.
Set/Read Channel Access Method. 0=Standard
ATMC
carrier-sense CSMA. 1=Time-Dievision Multiplex,
where user-data is transmitted in the unit's TDMA slot.
GPS Operation Mode. Set the PL version's Operating

IDLE TX Interval. Set the number of seconds between
IDLERATE
position transmissions when the unit is idle (has not
moved more than TRIGDX meters).
Privacy Security Key Code. Set the privacy key for
this device. It must be the same key as used on all
KEYPHRASE
other Raveon products in your system. It secures radio
transmissions from unauthorized reception. Set it to 0 to
disable security encryption of data.

MANDOWN
seconds that the unit may be horizontal befor triggering
a man-down alert. 0=disable.
Enable/Disable NMEA messages. Configures the M7
GX to output standard NMEA messages (GGA, GLL,
NMEAOUT
RMC) out its serial port. NMEAOUT 0 disables the
messages. NMEAOUT 1 enables them.
Set/Read NMEA message bit mask. The
NMEAMASK register contains configuration bits to
enable various NMEA standard messages from the
NMEAMASK
internal GPS receiver that will be sent out the serial
port. The parameter is the decimal integer value of the
mask.
Set/Read NMEA message rate. Set/read the number f
NMEARATE
seconds between NMEA messages from the internal
local GPS.
ID Prefix. Set an ID prefix. The prefix is 1-8 characters
PREFIX
that will be put in front of the ID when reporting an ID as
Company Confidential
