JP1 Remotes

[bilottag]

Can someone please help.
I am trying to program a URC-8090 B01 using IR3 and/or IR4. Unfortunately I am getting "No Response" from the interface check (IR4)regardless of whether I have the connector in one way or the other (turned around). In IR3 I get "no response" when the cable is one way and "Always reading "1" from inverted S7..." when I turn the connector around the other way.
I know it's not the connector because it works perfectly well with my URC-9800, my URC-8910 and my urc-9962 Kameleon.
Can anyone help with some ideas of what I'm doing wrong?
Thanks

It depends on what interface you are using, but you should try the 8090b01 with both the batteries in and out. If that doesn't work you might try with three batteries and a shim (dead battery or a piece of dowel covered with aluminum foil).

Although in your setup the problem might seem specific to the remote, it's a combination of PC Parallel Port voltage, interface used (if using the simple interface use 1k resistors not 10k), & batteries of the remote being downloaded. Because parallel ports differ so much, it's not an exact science.

I would like to recommend a simple workaround for this (relatively common) problem.

Rather than keeping a separate shim or a dead battery (that can get mixed in with your supply of good batteries), etc. what I do is, for the brief moments of up/download to/from your remote, simply install one of the batteries backwards. It will drop the total voltage provided to the remote sufficiently to get successful communication with the remote (and contraty to some claims) will do no harm to your remote or the batteries.
