Hi, I have an MX-980 and MSC-400 and noticed a problem I am having. Anything I do ends up causing all the IR flashers to illuminate. I "assume" this means they are outputting something. This may be causing some issues for me. Anyway, I have all the MX-980 commands configured for the proper ports on the MSC-400, and I also made sure the MSC-400 configuration and each device's configuration are only one port. I have 5 IR and 5 RS-232 devices. I even went in and put each device to an unused port for the signal type not used (unused IR port for the Serial) since they all list both under device properties. So far I have not been able to get only the flasher for the commanded device to flash. Is there another output all buried somewhere? Very strange. Everything does "mostly" seem to work (I have had some trouble with certain macro's but moving things around has helped some - and no these are not time related, since TV power on was first in the list and did not work until I moved some things around). Very strange...
