Thanks for this, yes, I see the way the IR signals could be detected in real time and send via RS-232. The question is, as you say, can these commands be received and retransmittted at the other end without external programming.
I'll contact Global Cache next week.
Thanks.

It just hit me that even if there could be another Golbal Cach¨¦ device as receiver, I would still need programming since the RS-232 ports on both DM-NVX devices need to talk to each other...
Oh well, thanks anyway.
