5. ROUTER DESIGN

5.9.2 Power connector PWR

Panel socket 2-pin.

Pin number Signal mark Description

1 VCC(+) Positive pole of DC supply voltage (+10 to +30 V DC)

2 GND(-) Negative pole of DC supply voltage

Power supply for router is required between +10 V to +30 V DC supply. Protection against

reversed polarity without signaling is built into the router.

The power consumption during receiving is 2,3 W. The peak power consumption during

data sending is 5,5 W. However, values of consumption can be increased, if some expansion

port is eqquipped. For correct operation it is necessary that the power source is able to supply

a peak current of 1 A.

Connector on the power cable connects into the power connector on the router head and

tightens locking screws (see ﬁgure below).
