3.6 Interface connections

The serial interface can perform the following functions:
- retrieve data,
- program and retrieve parameters.
Interface parameters are:
- transmission speed (Baud rate),
- parity bit,
- number of stop bits,
- address by which the master approaches the control instrument.
The interface parameters can be set in the programming mode.
RS232 Full-duplex transmission with the following features:
- asymmetric
- 3 lines
- point-to-point connection - 1 emitter and 1 receiver
- distance of data transfer: max. 30 m
RS422 Full-duplex transmission with the following features:
- symmetric
- 4 lines
- point-to-point connection - emitter and receiver (max. 32 units)
- distance of data transfer: max. 1500 m
RS485 Half-duplex transmission with the following features:
- symmetric
- 2 lines
- multi-point connection - emitter and receiver (max. 32 units)
- distance of data transfer: max. 1500 m
➜ Assign terminals 14 and 15 and where applicable 16 to 19 to the
corresponding interface.
