i-modul Modem 336 LL
Functions

Digital inputs
The i-modul Modem 336 LL 3.0 has two digital inputs, whose states can be transmitted
to the other i-modul Modem 336 LL 3.0 at the leased line via IO tunneling. The input
states of a i-modul Modem 336 LL 3.0 can also be queried via AT commands. The states of
both inputs is "HIGH" when connected. The state of an input can be switched to "LOW"
by connecting the according input 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.

Control output
The i-modul Modem 336 LL 3.0 provides two control outputs OUT1 and OUT2. IO tunnel-
ing allows that the outputs of one i-modul Modem 336 LL 3.0 reflect the states of the
inputs of the i-modul Modem 336 LL 3.0, which is connected via the leased line. The ini-
tial states of the outputs of the i-modul Modem 336 LL 3.0 can be set using AT com-
mands. After switching on, the outputs of the i-modul Modem 336 LL 3.0 are set to the
stored states.
Configuration with AT commands
In order to change the initial states of the out-
puts, use the command
<out>
is 0 for output 1, and 1 for output 2;
<state>
is 0 for “LOW” and 1 for “HIGH”.
AT*Y<out>,<state>
In order to set output 1 to “HIGH”:
AT*Y0,1
In order to set output 2 to “LOW”:
AT*Y1,0
To save the settings use the command
