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.
-1,
1-9999 (Decimal
number, not hex)
N.A.
By default the
Slot Number
is auto-set to
the MYID
SLOTTIME
TDMA Slot duration.
Configure the width of a TDMA
slot. 50mS increments.
50 - 1000
200
TDMATIME
Set/read TDMA Frame time.
The length of one
TDMA time frame, in seconds.
0-3599
10
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.
0, 1
0
(GPS Position
is priority over
data)
TRIGBITS
I/O Change Reporting.
Sets/reads 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. Note: all
input bit status is always sent each transmission,
regardless of this setting.
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…. Any bit set to one in this
parameter will set the particular bi
t to be “active low”.
Setting this to 0 will set all input bits to be active high.
This does not affect the actual state of the bit
transmitted over-the-air. It only effects the polarity
that causes a bit to trigger an event or a transmission.
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 enabled with the TRIGBITS. This is a HEX
number. Bit 0 is IN0, bit
1 is IN1…
0-FF
