I can attest to the fact that it does. With a simple cable on my Thinkpad I had nothing but trouble. Since I went with the Ultra I have not had a single problem with a great many different remotes.

I've never had a single problem with my laptop and a simple cable.

Interesting. The laptop I now use is Compaq Evo (3.25v), behaves a bit worse than the old Compaq Armada 300 (3.5v).
It just can't pull the line well enough. When remote batteries are new, I have to replace 2 with old ones. When slightly used, 1 replacement is sufficient. In and out, in and out - it's becoming a pest during quick IR trials.

I believe Nils clued me in a while back to the reasons and wrote about the battery swapping trick or ultra cable option. I just haven't acted on that advice yet. Does this ultra thing, by the way, have decent thumb screws or these pesty little screwdriver jobs my 'simple' cable has?

Mark, is USB an option to consider? why? why not?

Oddly enough I've never had any issues with batteries either. I've programmed about a dozen 8810's for friends and family so far.

I've been using an original simple design (10K resistors) cable with my Dell laptop for about 2 years (1994 remotes) with no problems. I did follow the advice in Tommy's construction manual when I built my cable and made a "dummy" battery out of dowel rod and aluminum foil. I always replace one of the batteries in the remote with the dummy battery and it works every time.

Thats what it comes down to. If you use a simple interface you may have to try different workarounds like with batteries, without batteries, old batteries, new batteries, standing on your head, special way of holding your mouth, and a dummy battery. With the ultra you don't need to worry about that as it compensates for the voltage mismatch.

Simple/personal choice. If you are happy with the workarounds then stay with the simple interface but since I work with so many different remotes and each one needed a different workaround I decided to convert to the ultra and happy I did.

My reasoning for going with the USB. :wink:

Plus, my laptop doesn't have serial or parallel ports when out of the docking station.

I agree on the USB as the long range way to go :idea: but I just have not had to make the jump yet since my laptop has the parallel port.

This battery replacement routine is a nuisance to me, so thanks for lots of good advice, as usual :D .

Yeah, Dell. Sure. I wish I had one. Desktop PC was fabulous. Ages ago, when we used Dells and Compaqs, Compaq repairmen used Dells, 'cause they worked :lol: .
