Power
The supply voltage 8...30 VDC is connected using 1.3 mm DC jack (centre connector positive) or
by using detachable screw post connector terminals 1 (+) and 2 (-). Both supply voltage connec-
tors are internally connected. The receiver is protected against wrong polarity of the supply volta-
ge. The supply voltage’s negative terminal is also used as ground for RS-485 and RS-232.
