Hi Scott,

I assume you are using RS232 from the PC to the controller? It would be 
challenging to have a 200' serial connection on copper. The first RS232 
specification talks about 50' maximum length at 19k2 but in practice 
this can be higher when speed is dropped. However, worth a try and if it 
doesn't work you can consider RS232 extenders. These typically use Cat5 
cable.

BR,
