Thanks to all for your advice. KRAZYK, you are correct that my time is worth money. However, I want to give this a shot but if I cannot get it to work to my satisfaction then I will be hiring a professional. My confusion is with creating the RS232 devices on the remote. I understand that they get created in the MSC400 and then get the macros created. I currently have the devices that are controlled by IR listed on the remote but no RS232 ones. How do I go about this? Thanks again for your advice.
