PR&E
●
Logic control uses stranded, 22 AWG, multiple-conductor, non-shielded, jacketed cable (equivalent to
Belden 9423, 8457 or 9421).
The number of conductors required 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 12 or 14 pins on the
logic connectors, only a handful are typically connected for any given application.

Crossover CAT-6 cable to connect the VistaMax Link connector to a VistaMax frame
●
Straight-thru CAT-5 cables to connect Dual Router kits to a VistaMax system LAN switch or a Dual
Selector to a 16x2 MicroRouter
Wire Preparation
All NetWave audio and logic wiring terminates in AMP MOD IV receptacle contacts (Figure 2-23). Stranded
wires of 22 to 26 AWG, with insulation diameters of .040 to .060 inch, can be used with the MOD IV
receptacle contacts.
Figure 2-23. AMP MOD IV Receptacle Contacts
To prepare shielded audio wire, perform these steps:
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 each signal wire insulation back 9/64" [3.57 mm].
5.
Crimp the receptacle contact onto the wire and insulation (Figure 2-24).

Note: Audio Cable Shielding – To follow recommended grounding procedures, you must sleeve
the drain wires with Teflon sleeving and cover all cable jacket cut ends with heat shrink
tubing to insulate the shield wiring.
Fabricate Logic control cables and UTP audio wires in a similar manner to the shielded audio wiring. Strip the
jacket insulation back 1½" [38.10 mm], sleeve the cut end with 3/4" [19.05 mm] of shrink tubing and strip
the insulation from each wire 9/64" [3.57 mm].
