NOTES

1/ Pins 1-8 can be used either to drive eight actuators with digital (on/off) signals, or can be digitally decoded to give 255 lines of digital (on/off) control.
2/ For colour control use the G, G and B High lines in digital mode to get 7 colour control. Each of the the Red low and high signals can be decoded to give 4 levels of brightness for each colour.
3/ The digital ground and analogue grounds are separate. Do not use the digital ground with analogue signals and vice versa.
4/ CAUTION: do not short these pins to ground or any other voltages as it may cause damage to your computer power supply. Insulate from any nearby pins and fuse at 1 amp max.

Connector CN4: Digital trigger inputs

Board Pin DB25 pin Function Usage
1 1 Trigger in TTL input (see note below)
2 14 Trigger in TTL input (see note below)
3 2 Trigger in TTL input (see note below)
4 15 Trigger in TTL input (see note below)
5 3 Trigger in TTL input (see note below)
6 16 Trigger in TTL input (see note below)
7 4 Trigger in TTL input (see note below)
8 17 Trigger in TTL input (see note below)

NOTE: The input lines can be used as 8 individual inputs for triggering or can be encoded with an external device to give 255 trigger combinations.
