Essential Info

The RU-VSQ4 is the ideal choice in most applications where up to four video signals need to be sequenced to a single output. The RU-VSQ4 has two rear-panel jacks for each of the four video bridging input stages. One jack is for the input signal; the other is a loop-through output of the source signal. If 75 Ohm termination of the input signal is required, the terminator (provided) is plugged onto the LOOP OUT jack. The output video signal is 75 Ohm back-terminated to provide unity gain into a 75 Ohm terminated input.

The front panel features four high-reliability keyboard style pushbuttons with LED indicators corresponding to each video input. When power is initially applied, the RU-VSQ4 sequences between the video inputs at the interval set on the recessed front-panel RATE control. If the button for an active source is pushed, the sequencing stops and the output displays that input. While the unit is holding at that video source, the HOLD LED flashes. When the operator again pushes the button for that channel, the sequencing resumes. If an unselected source button is pushed, that source is immediately selected. When a video source is selected, an open-collector output on the rear panel is provided to control other equipment (RDL RU-SX4A).

This item requires a 24V power supply such as the PS-24K for operation.
