General Figure2-7 shows a typical rear panel for an AC-powered DV-MUX3 unit. The rear
panel of DC-powered units is similar, except it includes a three-pin circular DC
power connector.
The DV-MUX3 has two 15-pin D-type female connectors located on the rear
panel, one for connection to the main link, and the other for the data channel. In ad-
dition, the DV-MUX3 rear panel includes two RJ-45 connectors for the two voice
channels.
Appendix A lists the pin allocations for the various connectors, and provides infor-
mation on the adapter cables available for each connector.

Grounding For your protection, the DV-MUX3 must always be grounded. Any interruption of
the protective (grounding) conductor (inside or outside the instrument) or discon-
necting the protective earth terminal can make this instrument dangerous. Inten-
tional interruption is prohibited.
Power Connections The DV-MUX3 does not have an on/off switch, therefore it will start operating as
soon as power is connected.
