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
with 3/4" [19.05 mm] of shrink tubing and strip
the insulation from each wire 9/64" [3.57 mm].
CRIMP TOOL OPERATION
A ratcheting AMP crimp tool with contact holder
(70-126) is included with each RMX
d or BMXd
console and with each VistaMax card frame.
If a tool is not already on-premises, one is included
in the optional 76-1901 NetWave/SMXd Tool Kit.
The MOD IV tool crimps both the insulation and
the wire barrels on the MOD IV receptacle contact
in one crimp.
To use the ratcheting crimp tool:
1.
Insert the contact into the contact holder with
the barrel openings up. Typically, the middle
holder is used (20 - 24 AWG wire). Flip the
holder up so it magnetically latches against
the crimp tool. The end of the insulation bar-
rel should be about 2 mm from the end of the
die. Close the tool handles one click (only un-
til the anvil holds the contact in place, as shown
in the cutaway view, below).
2.
Insert the prepped wire into the contact until
the insulation hits the tool’s stop. Hold the
wire in place while squeezing the tool handles
to crimp the contact onto the wire and insula-
tion. The tool handles automatically release
and spring open after the crimp cycle is com-
plete.
After all contacts on a cable are crimped, insert
and lock the contact into the appropriate connec-
tor housing following the pinout diagrams found
on page 2-20 (for audio) and 2-23 (for logic).
Insert the receptacle contact into the housing
with its locking tab side toward the locking tab
slots on the connector housing. A slight click can
be heard when the contact’s locking tab springs
up into the locking tab slot.
To remove a contact from a housing, the 70-
129 Contact Removal Tool (also included in the
Audio Wire, ready for insertion into an
