ante Posted September 14, 2005 Report Share Posted September 14, 2005 Hi Rhonn,The parallel port has 8 bits, it have to be done with the software. You can control 8 relays directly or 127 relays by manipulating with the software. 8) Quote Link to comment Share on other sites More sharing options...

GreekPIC Posted September 15, 2005 Report Share Posted September 15, 2005 This one is for 16. Since the LPT is 8-bit in theory you can have up to 256 outputs.Do a search on bin to dec converter IC's. Quote Link to comment Share on other sites More sharing options...
Staigen Posted September 15, 2005 Report Share Posted September 15, 2005 HiI belive http://www.techlib.com have one on their site, controling up to 32 outputs(relays)!//Staigen Quote Link to comment Share on other sites More sharing options...
