Terminal block
The terminal block is used to connect external signal sources or alarm switches,
as a relay output, a serial interface or as a power supply.
Options for using the serial interface include transparent data transfer, control of
connected devices or operation of the unit with a terminal program. Depending
on the setting, the serial interface uses the RS232 or RS422/485 standards. The
standard used depends on the current configuration (see pages 45 and 64).
Pin assignment
The pin assignment for the serial interface depends on the standard used:
To operate the alarm inputs connect each alarm input to a ground contact (GND)
via a trigger contact.
