Pin Description
A +13.8V
B Ground
Table 2: DC Power Connector Pin-outs.
For AC power, a standard IEC Mains connector is used (see Figure 3 below). An
appropriate version of power cord, relevant to the area of use, is supplied with the
SDB670 DMR base station (see Power Supplies, Page 21). Mains supplies should be in
the range of 100 V – 240 V AC, 50/60 Hz with an earth connection.

Figure 3: AC and DC Power Connectors.
The equipment must be installed so that the IEC connector can be easily removed
and/or the power socket should be readily accessible. All mains wiring must comply
with local wiring regulations.
Earth Point
On both the AC and DC versions, the earth stud on the rear panel is provided for
protective earthing of the equipment to a suitable protective earth point or to the
equipment rack, which itself must be electrically earthed. The earth point should be
connected using heavy duty earthing wire, with a capacity greater than mains feed to
equipment and with as few bends as possible, typically 6 mm Green/Yellow with 5 mm
eyelet tag.
P5 Ethernet
The P5 Ethernet connector uses standard network cable wiring for an RJ45, which is
detailed below in Table 3.
