Multi-Display Systems
Introduction
Overview
The 5100 Series displays allow multiple displays to
work together. The primary display is referred to as the
"master" display. Other displays controlled by the master
are referred to as "slave" displays. Slave displays get their
information from the master via 485 communications
(Terminals A, B, COMM).
Applications
Take-A-Number Systems (Standard)
To have multiple displays all showing the same number
in a Take-A-Number system, simply connect the displays
as shown in the wiring diagrams. You may wire push
buttons to any of the displays in the system. Pushing the
buttons connected to any of the displays will cause the
numbers to change on all of the displays.
No program-
ming is necessary for this option.
Multi-Window Service System
A Multi-Window Service System is a Take-A-Number
system with the ability to have displays over multiple
service counters. Each service counter display can show
the number of the customer that is actually being served
rather than the highest number. Because this is a complex
confi guration, there is an entire section of the manual
dedicated to this topic. Please see "Multi-Window Service
System" for further information.
Wiring Considerations
Connect slave displays to the master with 3- or 5-
conductor wire. The communications bus requires three
conductors. Communication runs can be up to 3,000 ft.
long. Five conductor wire [22 AWG] provides two additional
conductors used to carry power. As such, it is suitable
for short power runs. For longer runs, use 3-conductor
cable. On these longer runs, each display may be pow-
ered seperately, or the displays may be broken up into
groups powered by one adapter. For powering a group
of displays, 18 gauge, 2-conductor wire is recommended
for the power bus.
