Contact connector — Connect a remote contact
closure device to the switcher for remote control of
the switcher, or daisy chain the switcher to other
MSWs for remote control of the other switchers,
via this 5-pin captive screw connector.

The switcher must be in normal (manual) switch mode
for contact closure to work. See Mode selection, on
page 9.

To select an input using a contact closure device, such as an
Extron CCR 204 contact closure remote control (part #60-794-02)
or a locally constructed device, momentarily short the pin for
the desired input number to logic ground (pin 5). To force one
of the inputs to be always selected, leave the short in place. The
short overrides any front panel input selections.

You can also daisy chain multiple MSWs via the Contact
connector for front panel control of all switchers; touch the
input button on one MSW to switch all MSWs. Wire pin 1 to
pin 1, pin 2 to pin 2, and so on.

6

Power connector — Plug the external 12 VDC power supply
into this 2-pole captive screw connector. The power supply is
included with the unit. Figure 8 shows how to wire the
connector.

CAUTION

Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the MSW. Identify the power cord negative lead by
the ridges on the side of the cord (figure 8).

CAUTION

The length of the exposed (stripped) copper wires is
important. The ideal length is 0.2" (5 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the captive screw connectors
and could be pulled out.

Vertical interval switching

The MSWs switch inputs during the vertical interval of the
video signal that is input on input 1. In a genlocked system,
switching to any input is glitch-free if one of the genlocked
devices is connected to input 1.

Rear panel connections

The MSW switches on the vertical interval of input 1.
For seamless switching, ensure one of the genlocked
devices is connected to input 1.

in the captive screw connectors and could be pulled out.

To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.

The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.

Alternately, an Extron P/S 100 Universal 12 VDC Power Supply,
part #60-357-01, can power up to ten MSWs or other Extron
12 VDC devices using only one AC power connector.
