prefix. Default is a capitol letter 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 

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 

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 

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 

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 

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.
