installed in the PC. This cable is no longer needed.

At the Audio Tower, label and then disconnect all

cabling between it and external equipment and

accessories. Equipment and accessories include items

such as the Volume Controller Box, microphones,

speakers, headset jack boxes, audio lines to and from

the CEC/IMC, pager, recorder(s), Call Director, etc.

Remove the Audio Tower, Volume Controller Box,

speakers and related cabling. These items are no longer

needed.

2. (Console) Logic Board Removal

Review the procedures in the documentation included

with the PC relating to expansion board

installation/removal.

Remove the PC's outside cover in accordance with the

manufacture's instructions.

Identify and remove the Logic Board installed in one of

the PC's expansion slots. The large PC-to-Audio Tower

interconnect cable (disconnected in step 1) mated with

this board's DB-37 connector. The Dispatch Keyboard's

small round DIN connector also mated to a connector

on this board.

Using the screw which held the Logic Board in place,

install a blank expansion slot cover (not supplied).

Installation of this cover will prevent dust and other

foreign matter from entering the PC.

Replace the PC's outside cover.

Optional: Disabling of the Logic Board’s driver is

recommended. To do this, power-up the PC, booting-up

with Windows NT and then from Windows NT

Program Manager, open Control Panel. Next, run the

Services option and “stop” the WinStar (Wns27)

service. Exit Control Panel, shut-down Windows NT

3. PC-To-Enhanced Audio Enclosure Serial Link

Connect PC serial port COM1 to the Enhanced Audio

Enclosure in accordance with subsection

“PC-To-Enhanced Audio Enclosure Serial Data

Interconnect Cable” in this manual (page 23).

4. Console-To-CIM Serial Control Data Link

Normally, no console-to-CIM serial link changes are

necessary. However, if upgrading/replacing the plug-in

RS-422 board installed in one of the PC's expansion

slots (for improved static protection), the DB-25

connector which plugs to this board will, in most cases,

require rewiring. Older RS-422 boards have different

pin-outs from the newer boards. Refer to the plug-in

boards' documentation and/or LBI-39055 for pin-out

information. Also see the subsection in this manual

entitled “Control Data Link” (begins on page 12) and

Figure 7 in this manual.

5. Console-To-CIM Audio Link

If using existing modular cabling, cut the modular plugs

off the modular cables. Maintain connections to the

CEC/IMC Audio Concentrator Card or punch blocks.

Next, wire these audio lines to a male DB-25 connector

(not supplied) and mate the connector to the Enhanced

Audio Enclosure's "LINES 1-4" female DB-25

connector. See the subsection in this manual entitled

“Audio Links” (begins on page 16) for additional

information.

If using the pre-wired 100-foot audio cable, remove the

existing modular cabling connections from the

CEC/IMC Audio Concentrator Cards or punch blocks.

Next, wire the 100-foot audio cable to the CEC/IMC

Audio Concentrator Card/punch block in accordance

with the subsection in this manual entitled “Audio

Links” (begins on page 16).

6. Dispatch Keyboard

The existing (old) Dispatch Keyboard was disconnected

in step 1. If a new Dispatch Keyboard (with male DB-9

connector) is not supplied and this keyboard must be

utilized, replace its small round DIN connector with a

DB-9 connector (not supplied) in accordance with the

following table. Also see Table 23:
