Functions INSYS Modem 336 LL 2D/4D 5.x Originate / Answer
12.11 Digital inputs
The INSYS Modem 336 LL 2D/4D 5.x Originate / Answer has two digital inputs, whose
states can be transmitted to the other INSYS Modem 336 LL 2D/4D 5.x Originate / An-
swer at the leased line via IO tunneling. The input states of a INSYS Modem 336 LL 2D/4D
5.x Originate / Answer 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
AT*i
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.

12.12 Switch Outputs
The INSYS Modem 336 LL 2D/4D 5.x Originate / Answer 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 2D/4D 5.x Originate /
Answer mirror the input states of the INSYS Modem 336 LL 2D/4D 5.x Originate / Answer
connected via the leased line. The initial output states of the INSYS Modem 336 LL 2D/4D
5.x Originate / Answer can be set via AT commands. After the system start, the outputs
of the INSYS Modem 336 LL 2D/4D 5.x Originate / Answer 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.
AT*Y<Outp>,<State>
To turn output 1 on:
AT*Y0,1
To turn output 2 off:
AT*Y1,0
