bgarrett Posted January 21, 2017 Report Share Posted January 21, 2017 I am trying to control a IDK MSD 502 matrix switcher from Watchout using RS232. IDK tells me that the code to make this happen is @EXC,1 @EXC, 1 will trigger a shutter command that is stored in the switcher. I was able to make the switcher work in a terminal software, but when I hook it up to WO nothing happens. I tried to add $0D to the front and back of the code. I have the settings correct. Baud rate 9600, no parity. I will take any suggestions. Thanks, Bg 0 Quote Link to comment Share on other sites More sharing options...
Dataton Partner RBeddig Posted January 22, 2017 Dataton Partner Report Share Posted January 22, 2017 $0D is usually what makes the string go off. Always add it to the end of your string. If "@" is not interpreted in the right way when sent as "@", you might try to use the $40 which is the hex-code representing "@". 0 Quote Link to comment Share on other sites More sharing options...
zackboyd Posted January 22, 2017 Report Share Posted January 22, 2017 I'd start by verifying that the serial port you're using on the Display computer(not production) is COM1 in device manager. If that's correct, route that serial port back into a laptop or other machine in a terminal software(like putty) and make sure you're getting something back. If not, feel free to post/send me a link to your project and I'll take a look. PM me for contact info. 0 Quote Link to comment Share on other sites More sharing options...
