I tried the UIRT2 (pre-assembled from Luc, see girder.nl forums).
I have gone back to the IRmain.
a) The UIRT2 (HTPC internal model) wouldn't get totally reliable remote codes with a 7m cable for the IR receiver and senders.
I added the recommended inductor and capacitor filters at the end of the cable and this helped a lot. It was still not as reliable as an IRmain, running over a 7m serial cable.
b) The Girder UIRT plug-in cannot currently control Denon equipment.
The UIRT2 girder 3.2 plug-in needs to learn the raw signal in order to re-send the IR code. This plug-in learn doesn't work with Denon remote controls at present. I think the Denon remotes send a double code which prevents the learn from completing.
There is a fix proposed by the plug-in author, but not yet available. I have learnt and re-sent signals to control my IR lighting and Pioneer CLD-925 Laserdisc.
c) The IRman is what Bob Sorel's HTPC remote/Pronto collection is using. Using the IRman means you are "industry standard" and going to hit the least new problems when adopting other's pronto set-ups in future.
A nice feature of the UIRT2 is that is comes with a wake-on-lan cable, which allows the UIRT2 to be programmed to wake-up the PC when a particular IR button is pressed using wake-on-lan. My Abit BX6-2 motherboard will only resume from standby, not power-up using this. This can be re-wired a little to provide a Power switch pulse, but it's not something I'd like to do.
As I already have an IRman, once the Girder plug-in is fixed, I will use the UIRT2 in addition to the IRman, just for re-sending IR signals to my IR lighting and Denon AVC-A10SE amp. I'll also use to to power=on the HTPC once it uses a modern Pentium4 motherboard and bios.
I have an external UIRT2 pre-assembled and programmed by Luc spare. Make me an offer if you'd like to have it. I didn't realise it requires a 5v supply, even though it runs at the end of a serial COM cable, apparently because the PIC processor on-board needs a little more current than the serial port can usually supply.

Rob.
