INSYS Modem 336 LL

12.11 Digital inputs

The INSYS Modem 336 LL 4D/2D AC/DC has two digital inputs, whose states can be
transmitted to the other INSYS Modem 336 LL 4D/2D AC/DC at the leased line via IO tun-
neling. The input states of a INSYS Modem 336 LL 4D/2D AC/DC can also be queried via
AT commands. The states of both inputs after the system was started is "HIGH". The
state of an input can be switched to "LOW" by connecting the according terminal with
GND.
Configuration with AT commands
Query the state of the inputs
The states are output in the format x,y, where
x is the state of the input 1 and y is the state of the input 2.
0= LOW
1= HIGH

12.12 Switch Outputs

The INSYS Modem 336 LL 4D/2D AC/DC has two switching outputs, OUT1 and OUT2 on
the bottom of the housing. The outputs are potential-free relay switches. IO tunneling
ensures that the outputs of one INSYS Modem 336 LL 4D/2D AC/DC mirror the input
states of the INSYS Modem 336 LL 4D/2D AC/DC connected via the leased line. The initial
output states of the INSYS Modem 336 LL 4D/2D AC/DC can be set via AT commands.
After the system start, the outputs of the INSYS Modem 336 LL 4D/2D AC/DC are set to
the stored states.
Configuration with AT commands
Changing the initial output states via the fol-
lowing command:
<Outp> is 0 for output 1, and 1 for output 2;
<State> is 0 for Off and 1 for On.
To turn output 1 on:
To turn output 2 off:
