Default
GX
Display GPS settings.
Show an overview of the current GPS features and
configurations in the M7 GX.
-
-
GPS
GPS Operation Mode.
Read/Set the GX version’s Operating mode.
0 - 6
1
GPS&F
Reset all GPS (-GX version) parameters.
Set the GX version’s Operating
mode to GPS mode 4, and sets all GPS parameters to factory defaults. It
does not erase frequency or other radio-related parameters.
-
-
IDLERATE
IDLE TX Interval.
Set the number of seconds between position transmissions
when the unit is idle (has not moved more than TRIGDX meters).
0-9999
seconds
10
KEYPHRASE
Privacy Security Key Code.
Set the privacy key for this device. It must be
the same key as used on all other Raveon products in your system. It
secures radio transmissions from unauthorized reception. Set it to 0 to disable
security encryption of data.
2-16 ASCII
characters.
“RAVEON”
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
SLOTTIME
TDMA Slot duration.
Configure the width of a TDMA slot. 50mS increments.
50 - 1000
200
SLOTNUM
TDMA Slot Number.
Configure the slot number that this radio will use to send
its data in.
1-9999
The MYID of
the unit
TRIGBITS
I/O Change Reporting.
Which bits are used as transmission triggers. This is
a HEX number. Bit 0 is IN0, bit 1 is IN1….
0-FF
0
TDMATIME
Set/read TDMA Frame time.
The length of one TDMA time frame, in
seconds. M7’s may transmit once per frame, and only in their preset time-
slot.
1-3599
10
TRIGPOL
Polarity of the input bits.
0 = normal active high operation(causes unit to
transmit when it goes high), 1 = Inverted, active low. This is a HEX number.
Bit 0 is IN0, bit 1 is IN1….
0-FF
0
Active high
TRIGEX
Report on change.
Sets which input bits cause a report on change. If a
particular bit is a 1, then it will trigger a report when it changes. The input bit
must also be enable with the TRIGBITS. This is a HEX number. Bit 0 is IN0,
bit 1 is IN1…
0-FF
0
TRIGDX
Distance trigger.
Set a distance (in meters) threshold beyond-which the unit
will transmit its position and status. If set to 0, the unit always reports at the
TXRATE. If set to an distance greater than zero, then the unit reports at the
TXRATE intervals if it has moved this distance since the last report. If it has
not moved, it will still report its position, but at the rate set by IDLERATE. If
IDLERATE is set t 0, then the unit will not report its position when not moving.
0-999
0
TRIGSPEED
Speeding Report.
Set a speed (in kilometers/hour) threshold above-which
the unit will begin reporting its position and status. Set to 0 to disable this
feature.
0-999
0
TXRATE
GPS Report Rate.
Set number of seconds between GPS reports. This is
also the rate at which the internal GPS will measure position, speed, etc.
Even if the unit is not moving, the GPS periodically measures position and
speed to determine if it has triggered a speed or position transmission.
