The RU-VSX4is part of the group of RDL RACK-UP products. The compact design permits high-density installations, with three products mounted 

in a single rack unit. The RU-VSX4 may be used alone, or mounted using a wide variety of RACK-UP series options. 

 
APPLICATION:

  The RU-VSX4 is the ideal choice in most applications where four video signals need to 

be switched to a single output.  The RU-VSX4 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-

 termination of the input signal is required, the terminator (provided) is plugged onto the 

LOOP OUT

 

jack.  The output video signal is 75 

 back-terminated to provide unity gain into a 75 

 terminated input. 

 
The front panel features 4 high-reliability, keyboard-style pushbuttons with LED indicators corresponding 
to each video input.  The LED indicators show which video source is active.  If the button for an active 
source is pushed, all video sources are turned off until the next source selection. 
 
A front panel 

LOCAL/REMOTE

 toggle switch activates either the front-panel buttons or a rear-panel 

connected remote control.  In the REMOTE mode, the inputs are selected by an external momentary 
switch or open-collector closure to ground.  Five remote input terminals are provided; one for each video 
source, and one to shut off all video inputs.  Installing a jumper from the 

CTRL OFF

 terminal to ground 

permits the RU-VSX4 to be controlled by equipment providing a continuous closure

 

only when a source is 

to be switched on.  In this mode, the RU-VSX4 may be controlled by an RDL D SERIES-RC4RU          
wall-mount 4-button remote control, or OEM equipment.  When a video source is selected, the RU-VSX4 
provides an open-collector 50 mA output to control other equipment or modules. 
 
When a video source is requested, either from the front panel or by remote, the RU-VSX4 waits until the 
next vertical interval to switch to the requested video source.  If no video is present then the switch occurs 
instantly. This feature avoids the screen roll typically associated with unsynced video switchers. 
 
Wherever a video switcher is needed to provide wide-band video source selection, local or remote control, 
reliability, compactness and unsurpassed versatility, the RU-VSX4 is the ideal choice.
