Table 16 Rotary switch S
DIP switch T is used to configure the terminating resistors on the cable(s) to connect the systems:
- In case of a standalone system, T should be set to 0
- In case of connected systems, T should be set to 1, for the first system and the last system
in the daisy chain.
- In case of connected systems, T should be set to 0, for the systems between the first and
the last system of the daisy chain.
This will result in a daisy chain configuration where the communication bus is terminated at
both ends of the daisy chain.
