Technical Specifications - Screen Blanking Cable
The customer must supply their own cable. The cable must be designed so that pin 7 (RTS – Request to Send Output) and pin
8 (Clear to Send Input) of a DB9 female connector provide continuity only when the vehicle is stopped (for example, via a
switch on the accelerator pedal of the fork truck). All other pins on the connector must be left unconnected. If pins 7 and 8 do
not provide continuity (or the cable is removed), the VX3Plus screen remains blank.
