Product information "VS Unisystem 4 in 1 Selector (Single Monitor) Vector Labs Switcher"

The VS Unisystem selector lets you play up to four VS Unisystem or other Nintendo Pcb's in youe single monitor VS cabinet. Solid state switching for quiet reliable operation. Can use a mix of up to four of the adapter boards (Popeye, Mario Bros, JAMMA, vs Unisystem)

Each 4in1 Selector comes standard with two adapter power cables, additional cables can be purchased for $5 each. The ribbon cable does support up to four adapters. 


 To switch from side to side -

  • Hold P2 then move joystick left or right to switch sides.
  • The Unisystem adapter jumpers need to be set so that the selector knows that the game PCB is two sided

Jumper   A    B    C

  •                on  off  on   VS side A only (w/gun)
  •               on  off  off   VS side A only (NO gun)
  •               off   on   on  VS side A and side B (NO gun)
In order to use the VS unisystem selector you need to use the standard control panel without the light gun. If you want to play light gun games then the gun needs to be directly connected to the VS selector. Also each VS adapter needs to be jumpered with the correct configuration to match the VS board as below:
  • LO= jumper on
  • HI = jumper off
  • A = LO,  B = LO, C = HI  STANDARD DK ADAPTER OR PC10    
  • A = LO,  B = HI,  C = HI  VS UNISYS SINGLE NO GUN         
  • A = HI,   B = LO, C = LO  VS UNISYS DOUBLE NO GUN        
  • A = HI,   B = LO, C = HI  JAMMA ADAPTER                  


When you connect the light gun directly the selector it will automatically enable or disable the gun depending on the adapter selected.
-5v is not used on the VS system so the LED will not be lit. The gun has to be plugged into the VS selector before the cabinet is powered up. The bypass harness needs to be disconnected and the control panel has to have both joysticks/buttons hooked up.

In other words, the VS system needs to be in the factory configuration without any gun mods installed. The VS selector takes care of any control panel or harness switching between gun and non gun games.

Excellent Switcher Terrific Customer Service

I bought this to put multiple boards in my Nintendo VS Super Mario Brother cabinet. I am very happy with the way it works and the fact it gives you access to the other side of the VS board. had some issues at first, Joe helped me over the phone and resolved it no problem.
