Installation and commissioning of the TERM 24
6.2.1
Connection of the supply voltage
The supply voltage is 10...30 V DC (typically 24 V DC), applied to pins "10 - 30 V DC". Reference
ground is wired to "GND". The TERM 24 requires maximum 250 mA.
6.2.2
Connection of the serial RS232 interface (optional)
The RS232 interface is connected via the screw-type plug connector at plug X3. When connect-
ing, please ensure that the TxD and RxD signals of the TERM 24 and of the connected unit are
reversed (e. g.: connect TxD LOCON to RxD TERM 24) and that the "RS-GND" reference poten-
tials of both units are connected.
6.2.3
Connection of the DICNET bus interface
The DICNET bus (see chapter "DICNET") is connected via the screw-type plug connector X3
and the user number is set on the rear DIP switch ("0".."F").
All "" signals are interconnected and all "DICNET-" signals are interconnected on the
bus. The signals are not reversed.
The "RS-GND" reference potentials do not necessarily have to be interconnected, however, it
must be ensured that the potential differences between the DICNET users do not exceed 7 V.
The TERM 24 features a permanently installed bus termination resistor.
Please always follow the information in chapter "RS485 connection (DIC-
NET)"!
