Troubleshooting OLD Remote (for Gas Fireplace)

First thing is to shine any old known good IR receiver at a video camera , to check IR acceptance and then confirm your IR LED/s are emitting by doing the same

It's radio - not IR :(

Most radio systems are on 300/400 mHz. If you have anything that can burst in that range, try it. Start with a garage door opener transmitter. Most of the OEM sourced from the same suppliers, so there may well be a ready source out there as well.

Interesting! Yes, I have a GD remote handy - I'll give it a try. Not keen o n running through all 256 codes, but at least they're switch settable. Any idea what an "On" signal on one of these things actually is? Hopefully it' s the same for the fireplace. FWIW, the transmitter contains a Super Star T X13 DIP 18 pin IC (haven't been able to locate a data sheet), and the recei ver contains a PTC PT2272 (data sheet located!). Jumper settings may be dif ferent - hopefully I can locate a sheet or info on the TX13...

...if all else fails, I may wire up a dip switch in the remote and try cycl ing through all the possible settings...

ering if anyone's seen examples where the remote and receiver jumpers *were n't* identical for them to be matched up. One other odd thing; I don't get how the security code of the remote was "18" with the following settings: 2 :0 3:1 4:1 5:1 6:0 7:1 8:1 9:1. Nor can I make "57" out of: 2:0 3:0 4:1 5:

the jumpers might be binary coded decimal

if it was wired for 18

or binary where 18 = 00010010

both of those codes have (2) ones and since you said two jumpers were cut, this might make sense.

so try to work it out for both binary coded decimal

or straight binary

ver. I didn't receive a remote transmitter when I moved in.

easier said than done. The remote transmitter is old and unavailable exce pt on eBay. It's an early model with hardwired jumpers. The (used, fairly old) remote I bought has jumpers 2 - 9 with wires bridging the "jumpers," with two of the wires cut.

code 57, and the remote I purchased says it was factory set to security co de 18. So I'm thinking "Easy peasy! Just match the jumpers in the remote w ith those in the receiver." So that's what I did - I solder-connected a cu t jumper and cut one uncut jumper in the remote to match them up.

another idea, can you see a part number on the IC inside...

look up the data sheet for it

Now, I know that most of us here are best described as "tight" with the pennies, holding on until either Abe or the good Queen howls.

However, as I mentioned most gas log makers source from generic suppliers - and here is one:

Somewhere on that device will be either a manufacturer, serial or model number. So, you might be able to call the maker and get how to adjust the sender, or replace the sender entirely. Or replace the sender and receiver entirely.

Given how stubborn I am, writing for myself, I would try to work it out with the resources already in hand.

BTW: 01110111 = 119 in binary. 00111110 = 62

They both have 8 digits. About all they share.

Are you sure that the receiver is active and receiving?

Best of luck with this - I just cleaned out our gas-log preparing for winter.
