Application Software Installation
q
If necessary, obtain C3 Maestro application

Console-To-CIM Serial Control Data Link
q
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.

q
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"
(begins on page 14) for additional information.
q
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).

keyboard must be utilized, replace its small round
DIN connector with a DB-9 connector (not
supplied) in accordance with the following table.

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.
