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 following figures show the rear panels of
the various MMX 62 switchers (models indicated). The rear
panels of the MMX 42 series switchers are the same, except they
have four instead of six video and audio input connectors.

Power connection

Power connector — Plug the external 12V power supply into
1
this 2-pole captive screw connector. The power supply is
included with the unit. No damage will result if the power
connector is wired incorrectly, but the unit will not power up.
Do not tin the stripped power supply leads before
installing the captive screw connector. Tinned wires are
not as secure in the captive screw connectors and could
pull out.

way. The signal output by the switcher is in the same
format as the input.
