configuring parallel port

I have used my home made JP1 connector to my computer's parallel port for years. I just built a new computer, and not surprisingly the motherboard had no parallel port. I purchased a parallel port PCI expansion card (Roswill RC302) which I have configured to work on LPT1, and it works perfectly with my parallel printer, in DOS or Windows XP.

I just tried to change the programming on one of my OFA remotes, and using this parallel connection to IR I am unable to download from the remote. I get an error message that there is no recognizable interface.

It is not this remote, because then I went to try my other JP1 programmed OFA remotes, and it works on none of them.

Can someone tell me how I would configure this parallel port to work with IR? I guess I could go to USB, but I would prefer not to have to buy a USB cable.

Thanks.

You may have to get the port address of the parallel port from contol panel=>system=>hardware=>device manager=>etc etc. Somewhere in there, under resources it will show the port address. Then when you select JP1 parallel in IR, you choose "other" for select port address and type in what you read from the control panel.

Thanks for the help. After reading different posts, I tried to check the settings under Device Manager for my card, and the numbers for the port were nothing like the ones others have described. It lists the I/O for the LPT1 port as 9F00-9F07 and nothing like the typical 0328, etc.

So, I checked "other" under "parallel port address" and typed in 9F00, and it seems to be working. At least I was able to download the current settings from the remote. Hopefully it will work as well when I try to upload again the new changes.

Thanks all!!!

Glad to see that you got it working. As for the address being so different, that has to do with the fact that a parallel port built-in to the motherboard gets one of the legacy port addresses like 278, 378, 3BC, while an add-in card is relegated to whatever Windows wants to give it via plug and play. I've never seen Windows assign one of the legacy port adresses to an add-in card and I've never tried to force it. FWIW my add-in card got assigned FEE8.

For WinXP at least there is a radio button in Device Manager under LPT/COM to "allow assigning legacy devices" which I assumed meant it would use one of those ports when configuring the device. It didn't, but it also didn't make any difference as it worked out OK as is.

Again, thanks to everyone at this great forum for this extremely useful information.
