Joe, You mentioned that you recently performed several upgrades/ enhancements including the Remote I/O upgrade.
Was one of the enhancements "Improving the Immunity of the rear panel RS232 and audio connectors to RF." And if so, did you bypass L1 (RS232 ground return) on the Remote I/O module? The reason I ask is that I performed some of the same enhancements over the weekend but was reluctant to bypass L1 as I wasn't sure if that enhancement pertained to the Revision B remote I/O board which I had just installed. I was concerned that bypassing L1 on the new board might cause a problem. I was going to post the question here or to support but decided to wait and determine if RFI through the RS232 connector was an issue. Just a thought...
