INTERCONNECTING THE EQUIPMENT

PERSONAL COMPUTER

PC-To-Enhanced Audio Enclosure Serial Data Interconnect Cable

The PC-to-Enhanced Audio Enclosure RS-232 serial data link uses cable P29/5010150000 (350A1371P29). This cable has a female DB-9 connector on one end for mating to the PC's male DB-9 serial COM port connector. The cable's other end has a male DB-9 connector for mating to the female DB-9 connector labeled "PC" at the Enhanced Audio Enclosure. The cable is nine (9) feet long. It should not be modified in any way and "extension" cables are not recommended for this 19.2k baud serial link. Identical cables are also used between the Enhanced Audio Enclosure and theG￿Speaker Assemblies.

Mate the cable's female DB-9 connector to the PC's male DB-9 serial COM port connector used for Enhanced Audio Enclosure interfacing. Normally, the COM2 port is used. Mate the other end of the cable to the Enhanced Audio Enclosure's DB-9 connector labeled "PC". This interconnection is shown in Figure 1 but not in Figure 6.

Standard PC Keyboard

During dispatch operations, the standard PC keyboard is not used. However, during the console set-up process, access to this keyboard will be required:

∙ for file management (for example - AUTOEXEC.BAT and CONFIG.SYS file changes may be necessary)

∙to configure certain items via the Editor program (see LBI-39056 for details)

∙G￿to start the console's application program

Connect the standard PC keyboard to the PC in accordance with the manufacturer's instructions. The plug on the keyboard's cable mates with a connector on the back of the PC.

VideoG￿Display Monitor

Interconnect the video display monitor's video cable to the Personal Computer in accordance with the manufacturer's instructions.

ENHANCED AUDIO ENCLOSURE

All Enhanced Audio Enclosure interconnections are made at the rear panel of the enclosure. Secure the cables with cable ties as necessary.

Dispatch Keyboard

The Dispatch Keyboard interfaces to the console system via the Enhanced Audio Enclosure. This keyboard's part number is P29/7590182003 (350A1371P17). It is sometimesG￿referred to as the "custom keyboard".

Connect the Dispatch Keyboard to the Enhanced Audio Enclosure by plugging its male DB-9 connector to the female DB-9 connector on Enhanced Audio Enclosure's rear panel. On the rear panel, this connector is labeled "KBD". Its pin-out is indicated in Table 24.

NOTE

Do not over-tighten the screws on the DB-style connectors.

DeskG￿Mic (if used)

Connect the desk microphone (option CRMC3D or equivalent) to the Enhanced Audio Enclosure by mating its male DB-9 connector to the female DB-9 connector labeled "DESK MIC" on the Enhanced Audio Enclosure's rear panel. The desk mic's cable is five (5) feet (1.52 meters) long. The DB-9's pin- out is shown in Table 15. Observe the microphone priority NOTE in the following section; the desk mic has the lowest priority.

HeadsetG￿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

G￿"OPERATOR".

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 16 and 17.
