4.2.4 Serial connection

This connection is mainly used for the controlled mode or to configure the device.
RS-232
Only point-to-point communication is possible when using the RS-232 interface.
Never connect multiple DLS-C(H)/FLS-C(H)s on a RS-232 serial line
RS-422
It is possible to connect multiple devices on a single RS-422 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).
For RS-422 connections, use shielded twisted pair cables only! For detailed information following the RS-422 guidelines.

Ensure, that all DLS-C(H)/FLS-C(H)s are set to different ID numbers.
The RS-422 interface cannot be used simultaneous with the SSI interface.
