V-DCPI

Digital Protocol Interface

GENERAL

The Valcom Digital Protocol Interface conditions the

24-hour enhanced digital output from the Valcom

V-SER or V-2927 clock cards to allow the Valcom

communications systems using these cards to

provide clock correction data to a V-WMCA

Wireless Master Clock Transceiver, a V-WMCRA

Wireless Master Clock Repeater, or a V-CCU

2-Wire Clock Controller. The V-CCU is part of the

V-VCU package, which includes the V-CCU and a

power supply.

INSTALLATION

Precautions

Failure to observe the following precautions could

result in damage to the V-DCPI:

 Make all connections to the V-DCPI and

associated equipment with the input power

removed. Check and verify all connections

before applying power.

FIGURE 1: V-CCU RJ-11 DETAIL

Data is connected to the V-CCU, V-WMCA or

V-WMCRA via the two center pins of the “DATA

OUT” RJ-11 connector. Electrical shorting of any

RJ-11 pins or terminations may result in unit failure.

The 24V and GND connections are provided as a

power source for the V-DCPI Digital Protocol

Interface when used with a V-CCU 2-Wire Clock

Controller.

OPERATION

The green data output indicator will flicker when

correction data is supplied to the V-CCU outputs.
