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.

PACKAGE INCLUDES

1 Valcom V-DCPI Digital Protocol Interface

1 6-Pin Silver-Satin Cord

1 6-Pin RJ-11 Wiring Block

1 DB15 to RJ-45 Gender Changer

1 Ethernet Cable

SPECIFICATIONS

Output

Two individual RJ-11 data outputs

Inputs

RJ-45 for 24-hour enhanced digital from the

Valcom V-SER or V-2927 clock cards

-24VDC input power (for use when providing

data to V-WMCA or V-WMCRA only)

Dry contact closure input to display “Fire” or

“Bell” on wired digital display clocks that are

receiving data once a second.

Features

Data output LED indicator

Easy Connectivity

Dimensions/Weight

2.75”H x 7.70”W x 1.55”D

(6.98cm H x 19.55cm W x 3.94cm D)

1.5 lb. (0.68 kg)

Power Requirements

The V-DCPI requires -24VDC 50mA (1 VPU). The

unit may be powered by a V-CCU connection to the

V-CCU #1 RJ-11 or by connecting a suitable power

supply to the -24VDC input.

Environmental

Operating Temperature: -0 to +40° C

Humidity: 0-95% non-precipitating

Wiring Requirements

24AWG UTP, CAT 3/5/5E/6

Ethernet Cable

6-Pin Silver Satin Cord

6-Pin RJ-11 Wiring Block (for V-WMCA or

V-WMCRA connectivity). When used with a

V-WMCRA, the Wireless Master Clock

Repeater must be set to transmit mode.

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.
