Watchdog circuit
A long-term watchdog circuit is implemented. The power supply of the Wavecom
GSM/GPRS module and the “Communication Control” processor will be disconnected
for a few seconds after the selected reset period.
If a part of the DinBox GSM/GPRS is ‘locked’ after e.g. an unexpected high ESD
discharge, surge pulse or an internal lock-up, this watchdog will always insure the
continuity of communication.
“Communication Control” Processor
This processor can monitor the whole communication process. This processor will also
control the 4 I/O lines and will perform the necessary action when input changes are
detected or when data is received to change output pins.
We have different basic “Communication Control” applications available :
DinBox GSM
-
2 input – if input is changed -- SMS send
- 2 output – SMS received – output will be changed
-
1 input – SMS / 1 output SMS
DinBox GPRS
-
1 input – to open a socket / 1 output – active when the socket is opened
-
2 input – if input is changed – send predefined message in socket to a host
-
2 output – receive predefined message in socket from a host – output will be
changed
The software for this “Communication Control” processor can be adapted for special
customer needs.

and existing implementations.
