AE/LZB 119 1894 R1A INTERCONNECTING THE EQUIPMENT

Headset Jacks (if used)

At the selected location, secure each headset jack box

(part of option CRCN1W or equivalent) to the mounting

surface using the four (4) #10 thread-forming screws

supplied in the installation kit or use alternate hardware

if required (not supplied). Before mounting, verify

adequate clearance is maintained for the headset's plugs.

If using both jack boxes, label them "SUPERVISOR"

and "OPERATOR" as required (per cable

interconnections accomplished in the following

paragraph).

Connect each headset jack box to the Enhanced Audio

Enclosure using the 6-foot (1.83 meters) cable supplied.

This cable (part number 19C337102P1 supplied with

CRCN1W) has male DB-9 connectors on both ends.

One end mates with the female DB-9 connector at a

jack box and the other end mates to the female DB-9

connector at the Enhanced Audio Enclosure's rear

panel. The connectors on the rear panel are labeled

"SUPER H/S" and "OPER H/S" for the supervisor

and operator headsets respectively. Interconnect the

cables accordingly. The DB-9 connectors' pin-outs are

indicated in Tables 15 and 16.

NOTE

Operator microphone priority is (highest to lowest):

• Operator Headset Mic (highest)

• Boom/Gooseneck Mic

• Desk Mic (lowest) (lowest)

The boom/gooseneck mic has priority over the desk

mic when no headset is connected. Desk mic audio

and PTTs are ignored if a headset or

boom/gooseneck mic is connected.

Boom/Gooseneck Mic (if used)

A boom microphone (option CRMC3E or equivalent)

or a gooseneck microphone (option CRMC3F or equivalent)

may be connected to the Enhanced Audio Enclosure as

follows:

Mount the microphone in accordance with the

instructions supplied with the mic. With the gooseneck

microphone, the supplied male DB-9 connector must be

soldered to the cable's wires in accordance with Table 8

after the mic's cable is routed through the mounting

surface. Connect the boom/gooseneck male DB-9

connector to the female DB-9 connector labeled "B/G

MIC" on Enhanced Audio Enclosure's rear panel. Cable

length is four (4) feet (1.22 meters). Table 13 indicates

the "B/G MIC" connector's pin-out.

CAUTION

DO NOT

connect a boom or gooseneck

microphone to one of the other female DB-9

microphone connectors at the rear panel of the

Enhanced Audio Enclosure. Damage to the mic's

magnetic voice coil may occur.

NOTE

All boom and gooseneck mic connectors (male DB-

9) must have pins 2 and 3 jumpered together so the

sense circuit will be active when the mic is

connected to the Enhanced Audio Enclosure.

Footswitches (if used)

Two (2) female DB-9 connectors are located on the rear

panel of the Enhanced Audio Enclosure for footswitch

interconnections. Footswitches used with the C3 Maestro

dispatch console include single-footswitch option CRSU3B

and dual-footswitch option CRSU3C. On the dual-

footswitch, one switch (PTT) keys the mic and the other

switch is a monitor switch. A single-footswitch provides

only a PTT function. See Tables 19 and 20 for specific

connector pin-out details. Footswitch operation is as

follows:

•

Depressing the PTT switch on a footswitch

connected to the "OPER FT. SW." DB-9

connector will activate the operator's headset mic if

the headset is connected. If the headset is not

connected, the boom or gooseneck mic will become

active when this footswitch PTT switch is

depressed and/or the desk microphone is PTTed.

•

Depressing the PTT switch on a footswitch

connected to the "SUPER FT. SW." DB-9

connector will activate the supervisor's headset mic

if the headset is connected.

•

If a dual footswitch is connected to either the

"OPER FT. SW." or "SUPER FT. SW." DB-9

connectors, depressing its monitor switch will
