The external GPI control lines 'a' to 'f' at the frame remote connectors are
provided to allow remote control and/or remote status indication. Line 'a' is
assigned as a GPI output to provide remote indication of input presence.
The GPI output is fitted with 6800 ohm pull-up to +5V and 270 ohm series resistor
so it can drive an LED directly. If the series resistor is shorted out, it can drive a
bulb at +45V 500mA max.
