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 transmission and
operation of the unit with a terminal program. Depending on the setting, the
serial interface uses the RS232 or RS244/285 standards. The standard used
depends on the current configuration (see pages 41 and 55).
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.
