We provide modular electronic systems for use in display and
exhibition.

Our Power/Con module is a digitally controlled power outlet.
It uses TTL level signals as you requested.  When used in
conjunction with our Intelligent Interface Module up to four
Power/Con units can be controlled by a Mac or PC.

For further information on these modules and others please
