Relais controlling through R232

hello,

I got a problem with Relais controlling through R232. I found this file in forum named'Relaiskarte_8Fach_RS232.llb'. When I try to open the file'Relaiskarte 8Fach RS232 Open-Close Channel.vi', there is a ctl file named"com1_12port.ctl" which could not be found. then the whole program does not funktion either.

it would be very nice if someone could help me out here.

best wishes.

Hi!

 

I wanted to control relays with the serial port to, and find it is very much easier with the parallel port... pin 2 - 9 are 0-5v ttl output and pin 18-25 are associated gnd.

 

I hope that will help you.
