needed is determined by the application.
Typically, cables with five or eight wires are
most often used for constructing logic cables
since even though there are twelve or four-
teen pins on the logic connectors, only a
handful are typically connected for any
given application.
• Crossover CAT-5e/6 cable to connect the
KSU Facet connectors to a VistaMax frame.
• Straight-thru CAT-5 cable to connect the
KSU Ethernet connector to a VistaMax sys-
tem LAN switch.
WIRE PREPARATION
All RMX
d
audio and logic wiring terminates in
AMP MOD IV receptacle contacts at the console.
Stranded wires, of 22 to 26 AWG with insulation
diameters of .040 to .060 inch, can be used with
the AMP MOD IV receptacle contacts.
Follow these steps for audio wire preparation:
1 Strip the cable insulation jacket and foil shield
back 1½" [38.10 mm].
2 Remove the foil shield and sleeve the drain
wire with 20 AWG Teflon sleeving. Leave
9/64" [3.57 mm] of the drain wire exposed.
3 Cover the cut end of the jacket with 3/4"
[19.05 mm] of heat-shrink tubing. Shrink this
tubing, centered on the jacket cut end, to hold
the drain wire sleeving in place.
4 Strip the signal wire insulation back 9/64"
[3.57 mm].
5 Crimp the receptacle contact onto the wire
and insulation.

e: To follow recom-
mended grounding procedures, the drain wires
must be sleeved with Teflon sleeving and heat
shrink tubing must cover all cable jacket cut ends
to insulate the shield wiring.
Logic control cables are fabricated in a similar
manner to the audio wiring. Strip the jacket insu-
lation back 1½" [38.10 mm], sleeve the cut end
Cabling and Wiring
Before installing the RMX
digital
console, cre-
ate a facility wiring plan to list the console inter-
connections with all peripheral devices. Identify
and create tags for the audio and logic cabling.
List each connection in a master facility wiring
logbook to facilitate the wiring installation, any
future system wiring changes, equipment updates,
and system troubleshooting.
Refer to the Quick Connection Guides, on pages
2-18 to 2-24, for information on audio and logic
connection. See page 2-13 for a block diagram for
each type of logic interface.
CONNECTOR ACCESS
All audio, logic and data connections are made
on plug-in connectors. They are hidden in normal
operation below a card access cover that extends
across the console behind the user control panels.
To access the connectors, open up the card ac-
cess cover by lifting from the front using the thumb
catches on either end of the cover. It is hinged to
open toward the rear and stay open.
Caution: Make sure the cover is fully open so
that it does not accidentally fall shut.
REQUIRED CABLES AND WIRE
The following types are required:
• Analog audio connections require two-
conductor, stranded, insulated, shielded
cable using a separate shield drain wire
(equivalent to Belden 8451, 9451 or 8761).
• AES/EBU connections use 110 ohm two-
conductor, stranded, insulated, foil-shield
cable containing a separate shield drain
wire (equivalent to Belden 1800A).
• Logic control cables require stranded, 22
AWG, multiple-conductor, non-shielded,
jacketed cable (equivalent to Belden 9423,
8457 or 9421). The number of conductors
