TALKBACK INTERCOM SYSTEM

V-2927 CLOCK CONTROL CARD

FOR THE V-2924A

INTRODUCTION

The V-2927 Clock Control Card is an optional plug-in card designed for use with the V-2924A

Talkback Intercom System with a V-2928 Option Card. It provides correction and control

functions for various impulse and synchronous clocks. The V-2927 also provides a digital output

used with the V-DCPI, Digital Clock Protocol Interface, to provide time correction data to Valcom

wired and wireless clocks. Programming of various clock types is performed via Windows

compatible Programming Tool. The V-2927 requires the use of the V-CIO Clock Interface Board

when used with mechanical time clocks.

DIMENSIONS/WEIGHT

•5.30”L x 3.00”W x 1.10”D

(13.46cm x 7.62cm x 2.79cm)

•0.9 lbs. (0.41 kg)

MINIMAL SYSTEM REQUIREMENT

•V-2924A Control Unit with V-2928 Option Card

•V-2927 Clock Control Card

•Rev 2.00 Programming Tool

•Rev 2.02 Control Unit Software

•486 or higher personal computer with Windows 95, Windows 98 or Windows NT 4.0

operating system, 8 MB RAM, 30 meg free system disk space

•V-CIO Interface Board (for impulse clocks)

•1 available DB9 serial communications port

OPERATION

The V-2927 Clock Control Card installs into connectors J3 and J4 shown in Figure 1. The output

connections are presented to the V-CIO Clock Interface Board via P2, DB15 male of the V-2927

Clock Control Card. Two independent clock ports, consisting of two normally open contacts

each, are provided. These ports work independently of each other and allow the system to

control two clock types simultaneously. A status LED is provided for each relay to indicate

activity. An administrative code, (#97XX, with XX being number of minutes to advance), is

provided to manually correct or advance various impulse clocks.

(Default code is 01).

INSTALLATION

The V-2927 must be installed prior to programming its available options.

WARNING: Disconnect main power before servicing!

•Remove the side plate and top cover of the Control Unit and set aside

•Remove and discard plate covering connector port opening for Clock Card DB15

•Remove four standoff nuts from Option Card

•Install 4 standoffs (shown in Figure 1)

•Connect J1 of Clock Card to J3 (shown in Figure 1)

•Connect J2 of Clock Card to J4 (shown in Figure 1)

•Press Clock Card firmly in place to make sure connectors are seated properly

•Install and tighten 4 standoff nuts on V-2927 board

•Replace top cover and side plate of the Control Unit and plug in the power supply

•Plug Clock Card connector into P2 (Clock Card Connector Port - See Figure 1 for location)

•Make connections to V-CIO board if mechanical clocks are being used (See Figure 2 for

location)
