PREFIX
ID Prefix.
Set an ID prefix. The prefix is 1-8 characters
that will be put in front of the ID when reporting an ID as
a waypoint name. A dash means no prefix. Default is a
capitol letter V.
1-8 ASCII
characters
Set it to “0”
for no prefix.
V
PROX
Proximity Alert.
Set a minimum proximity distance
(meters). When any
RV-M7 GX
with properly configured
ID codes and KEYPHRASE comes within this many
meters of this unit, a proximity warning is triggered. The
report interval will be at the TXRATE setting, and report
the proximity warning at least 8 times or until the
distance between the two
RV-M7 GXs
increases beyond
the PROX distance.

REPEAT
Enable -GX Repeating.
This simple command enables
the repeater feature of the
RV-M7 GX
, and configures it
for standard operation. The user may alternately use the
ATX and ATRX commands, but they are more
complicated to use. This command enables the unit to
repeat all messages it receives, as long as the first digit
of the 4-digit ID matches its first digit. (It repeats IDs
0001 thru 0999).

0
REPORT x y
Set duration of Location/Status Reporting.
This is a
static command (not stored in EEPROM). This
command sets how many seconds a unit should report
for. Report 0 disables GPS reporting altogether.
REPORT 1
re-enables normal operation.
Report 1 xx
enables the unit to report for xx seconds.

1
SLOTQTY
Quantity of TDMA Slots.
Normally this parameter is set
to 1. Each unit gets one slot. To facilitate data
transmission, it is possible to set this to a number other
than 1. For example, if set to 3, and the ID of the unit is
0008, the unit will be allowed to transmit in slots 8, 9, and
10.
1-9999

SLOTNUM
Change the TDMA slot number.
Use this command
with caution! This will change the TDMA slot
assignment, leaving the ID (MYID) unchanged.
Typically, the ID and the slot number are the same.
Once this command is used, the TDMA slot number for
this transceiver to will no change if the ID of the device is
changed. Set SLOTNUM to -1 to force the Slot Number
to be automatically set to the MYID of the radio. This is
the factory default setting.

SLOTTIME
TDMA Slot duration.
Configure the width of a TDMA
slot. 50mS increments.

TALKERID
Set/read the talker ID.
The TALKERID is the two-digit
prefix for the $xxTLL message.

GP
TDMATIME
Set/read TDMA Frame time.
The length of one TDMA
time frame, in seconds.
0-3599

TDMADATA
Set/read TDMA Data Priority.
Configure the unit to give
transmit priority to serial port data over GPS position
data. 0=GPS position priority, 1=Serial Data priority. If
set to 1, GPS position transmissions are suppressed
when there is serial port data to send. If set to 0, GPS is
always sent, and extra space in TDMA slot will be filled
with any available serial-port data.

as “transmission triggers”. This is a HEX number. Bit 0
