INSYS Modem 336 LL
IO tunneling
The input states of the INSYS Modem 336 LL 4D/2D AC/DC in answer
mode are directly output to the outputs of the connected INSYS Mo-
dem 336 LL 4D/2D AC/DC in originate mode, and vice versa. The in-
puts states are transmitted crosswise between the devices. In addi-
tion, the input and output states of the INSYS Modem 336 LL 4D/2D
AC/DC can be queried via AT command.

SYS Modem 336 LL 4D/2D AC/DC can still be switched from one op-
erating mode to the other one via AT commands.
Configuration for the operation in two-wire or four-wire mode
The INSYS Modem 336 LL 4D/2D AC/DC can be switched from two-
wire mode to four-wire mode via AT commands.
