It is controlled via a computers RS232 serial port which has several advantages over the parallel port. It can be used with any computer and operating system. Serial cables can be much longer (up to 35 metres) allowing 'remote' control. Use our RS232/RS485 convertors and distance of over a 1000 metres can be obtained. Simple serial ASCII commands are sent from the PC to control the relays and read the isolated inputs. It can be controlled via a terminal emulator program such as RealTerm or HyperTerminal. All components are provided including a plastic case with pre-punched and silk screened front and rear panels to give the kit a professional and attractive finish as shown in the photos. Gold plated DS PTH PCB. Finished Dimensions (mm): 140Wx110Dx35H.
