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).
RESPOND
Response slots.
Configures special slots
that can be used only in response to over-
the-air commands or data
acknowledgement. See the Raveon tech
note “High Performance TDMA Systems
Engineering” for more information
Use RESPOND 0 to disable.
Disabled
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
SLOTTIME
TDMA Slot duration.
Configure the width
of a TDMA slot. 50mS increments.
50 - 1000
200
SMLISTEN
Set Listen Slots.
Used in Sleep Mode 5 to
set the slots that data will be received on.
See the section on Battery Life and Power
Savings for more information.
Disabled
SUM
Send Update Message.
Immediately sends
a position report to the configured TOID.
Will wait for a response slot if configured to
do so.
N/A
N/A
TDMATIME
Set/read TDMA Frame time.
The length of
one TDMA time frame, in seconds.

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….
IN2 is the serial data input, so if the unit is
used to send data, do not set TRIGBITS to
a number greater than 3.
0-7
0
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.
