Wiring the Dispatch Consoles
All configuration on the console audio interface units should be done before their final
mounting. This is because access to the necessary potentiometers will mostly be prevented
by the position the units get mounted in.
The mounting brackets provided with the Model 4219 can be attached in any orientation
facilitate the mounting of the unit at a console position. It may also simply be set on the
desk top.
Voice and Data Jacks
Two 6-conductor modular telephone-type jacks labeled “VOICE” and “DATA” provide
connections to the CCE. The modular cords that plug into these jacks are typically
connected from the console to a duplex wall jack (or directly to the punch-down block),
which is, in turn, connected to the CCE.
Console Expander Connections
Console expanders communicate with the dispatch console via a serial data loop. A
system can include as many as three expanders per operating position. Each panel has a
“Loop In” and a “Loop Out” connector. Every “Loop Out” must be connected to the next
panel’s “Loop In” with four-conductor modular telephone-type cable, in daisy chain
fashion. If there is only a dispatch console at the position, the “Loop In” and “Loop Out”
connectors must be connected.
Headset/Handset Jackbox Connections
The headset jack connector on the back of the console unit connects to Zetron headset and
handset jackboxes or the Telephone Radio Headset Interface (TRHI). Refer to Accessory
Installation
on page 219 for a description of these functions.
Auxiliary Audio Connections
The console has additional audio signals available on the AUX AUDIO connector behind
the console. Most of these signals are used when installing optional equipment. The
mating screw terminal connector is supplied with the console. The connector pin-out is
shown in Table 70 .
