Display the elements of the stored configuration which differ from factory
default.
The WI-MOD-9-D has two sets of configuration parameters - a set stored in non-volatile
memory and an active set in RAM memory. Normally on start-up, the configuration is read
from the stored memory to the active memory. Changes can be made on-line to the active
configuration which are not stored.
Transmit and Receive Hold-off times
Transmit holdoff
ATS16=x
where x is the delay time in msec (0 – 255)
For example, ATS16=200 results in a transmit holdoff delay of 200msec.
Receive holdoff
ATS15=x
where x is the delay time in msec (0 – 255)
For example, ATS15=80 results in a receive holdoff delay of 80msec.
Radio Message Signature
- refer section 3.9
ATS21 = 0, 1, 2 or 3
1 is the default value
To be compatible with old modules with fixed signature, set to 0. If a new system, set to 2 or 3
to separate from other WI-MOD-9-D systems in the same area.
