Installation

4. For furniture mounting, drill 3/32” (2 mm) diameter pilot holes, 1/4” (6.3 mm) deep in the mounting surface at the marked screw locations.

5. For furniture mounting, insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until just less than 1/4” of the screw protrudes.

To select an input using a contact closure device, momentarily short the pin for the desired input number to logic

CONTACT 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.

CAUTION Power supply voltage polarity is extremely important.

8. For projector mounting, secure the MSW to a projector mount by inserting the mounting bolt through the bracket’s slotted hole.

Rear Panel Connections

1SDI Inputs (1 through 4) connectors — Connect SDI video inputs to these BNC connectors.

2SDI Outputs (A and B) connectors — Connect one or two SDI devices to these BNC connectors. The MSW outputs re-clocked SDI outputs.

3Contact 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

Applying power with incorrect voltage polarity could

damage the power supply and the MSW. Identify the power

cord negative lead by the ridges on the side of the cord.

4Power connector — Plug the external 12V power supply into this 2-pole captive screw connector. The power supply is included with the unit. Figure 5 shows how to wire the connector.

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 be pulled out.

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