APPENDIX B - DOWSER (DIMMER SHUTTER) CONTROL
The PlusCard is designed with an external I

C communications port to supply
power and control signals to an external dowser. This is connected via the 6 way
connector on the rear panel of the colour changer. When the dowser is connected,
it is sensed via the port and an extra control channel is allocated for dowser drive.
This means that all modes have one extra operating parameter as follows:
The dowser can be set to default as the last control channel via a hardware jumper
on the pcb (J23).
For furtherinformation on the control of dowsers and external devices with the
Pluscard, please contact Rainbow Colour Changers.
