RS232
Only point-to-point communication is possible when using the RS232 interface.
Never connect multiple DLS-C(H)/FLS-C(H)s on a RS232 serial line
RS422
It is possible to connect multiple devices on a single RS422 line. To ensure proper operation, strict Master-Slave communication must be
applied. It is important, that the Master has full control of the communication and never initiates a new communication before termination of
the previous communication (answer from the DLS-C(H)/FLS-C(H) or timeout).
Ensure, that all DLS-C(H)/FLS-C(H)s are set to different ID numbers
