Martin Rush SM 650 Remote Wiring

I am not sure if this uses the same pinouts as JEM machines - I think it may have been designed by JEM.

If so the pinout is
1=Ready LED (open collector)
3=+15V output
4=Heat LED (open collector)
5=0-10V smoke control (0-1V= standby 1-10V=variable smoke)


You could verify this by putting an LED with series resistor between pins 3 and 4, or 3 and 1.
