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 D9 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 VX7 screen remains blank.
