Digital Inputs and Potential-Free Outputs

The INSYS GPRS 5.1 serial has digital inputs and outputs. The outputs can be switched via
AT commands to control external functions. The inputs can be used to trigger an action
of the INSYS GPRS 5.1 serial. The inputs can be used to dial a connection to an AutoDial
destination or to send an SMS. The action is triggered through a change of the input
from HIGH (inactive) to LOW/GND (active). The level change is accepted after 0.3 sec-
onds, i.e. the input is debounced. In addition, there is the possibility for IO tunnelling, i.e.
transmit the input states via a TCP connection to another INSYS GPRS 5.1 serial or a serv-
er.

inputs changes at the same time, the input state 1 will be evaluated first. If the state
