VDA110M User Manual V1.1
3.2 General purpose interface
GPI outputs use switch-closure to indicate VDA110M status. When closed circuit, the
GPI line is connected to Frame Ground.
Each GPI output can drive a 24V bulb (max current 500mA).

Table shows Pin number (Remote number)
Note:
Remote 1 and Remote 3 are 26 way high density ‘D’ type female sockets and frame
ground is pin 2 and +5V @500mA is pin 1 in each case.
Remote 2 and Remote 4 are 26 way high density ‘D’ type male plugs and frame ground is
pin 6 and +5V @500mA is pin 15 in each case.
