Rear Panel Cabling
All connectors are on the rear panel. The type and layout of the
connectors on the rear panel will vary, depending on the model
of the switcher. The rear panels of the MMX 42 series switchers
are similar to the MMX 62 series switcher, except they have four
rather than six video and audio input connectors.

Figure 2-8 — Power connector wiring
C The length of the exposed (stripped) copper wires is
important. The ideal length is 3/16 inch (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the direct insertion connectors and
could be pulled out.
Use the supplied tie-wrap to strap the power cord to the
extended tail of the connector.
N Do not tin the power supply leads before installing in the
direct insertion connector. Tinned wires are not as secure
in the connectors and could be pulled out of the connector.
