4.Application Software Installation

If necessary, obtain C3 Maestro application software V5.0 (or later).

Install this software on PC's hard disk drive in G￿accordance with the supplied instructions.

Optional: Delete the old C3 Maestro application software from the PC's hard disk drive.

5.ConsoleG￿-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 6 in this manual.

6.ConsoleG￿-To-CIM Audio Link

If using existing modular cabling, cut the modular plugs off 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"

G￿(begins on page 14) 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 14).

7. DispatchG￿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.

Audio Tower "FOOTSWITCH 1" should now be used as an operator footswitch. Connect it to Enhanced Audio Enclosure's "OPER FT. SW." connector. This footswitch keys all non-supervisory mics. See the subsection entitled "Footswitches (if used)" in this manual (page 19) for additional

G￿details.

Audio Tower "FOOTSWITCH 2" should now be used as a supervisor footswitch. Connect it to Enhanced Audio Enclosure's "SUPER FT. SW." connector. This footswitch keys only the supervisor's headset.

10. Speakers

Speakers used with the Audio Tower are un-amplified units; therefore, they cannot be used with the Enhanced Audio Enclosure. Speakers used with the Enhanced Audio Enclosure are amplified units and each includes a volume control. The Volume Controller Box is not employed in Enhanced Audio Enclosure applications.
