JP1 Remotes

Also, just for your info, here are the device codes that correspond to the 2 hex codes that you posted:

01FF = 128.255
807F = 001.254

The number before the decimal point above is the "device code" and the number after is the "sub-device code". We just use the decimal point as a shorthand notation, it's not really a decimal point number.

Here's an expanded list of UEI setup codes that match 128.255:
Cable/0194
Cable/0290
Cable/0368
Cable/1594
Cable/2242
Cable/2863
Cable/4076
Cable/4290
Cable/4386
TV/2486
TV/2804
TV/2859
TV/3566
Video/3805

There's only 1 setup code (that I know of) that matches 1.254: TV/2062

Serial is a little dated.

No I don't know about loading code into the MX900. Never had to do it. I did look at those cables. The 2nd link was the only active one on that JP1 page.

According to this really old thread at RC, there is a tool called "Universal Browser" that allows you to update the MX-900. Do you have that tool? (It's possible that there is a newer, different tool now, as that thread is from 2007).

The user manual for the MX-900 also mentions the Universal Browser on page 17:

If you get to the point where you can enter Pronto hex, I'll generate the codes for you.

Ebay links by their very nature don't stay active for ever. I have tried, as best as I can, to describe what you need to search for in the thread itself. I just provide a few links as a convenience. I do try to go back to the thread every few months to replace the links, but I don't keep on top of it.

Thanks for the additional info. Yes, that Universal Browser I recognized the name. To use that aren't you using the USB cable connection on the remote like you do to load config files? There is a unused 8 pin solder connection on the PCB that use to have a header that doesn't anymore. Isn't that the serial port?

Understood about the links, I was just mentioning that to you in case you wanted to update the list.

All I know about the MX-900 is what I found during my last Google search, and I posted that info.

To use the universal browser in the mx-900 editor, once you open the software, the icon second to the end at the top of the page, is universal browser, last icon being the live update.

Click on the universal browser, a box with three panels appears, above them is the word HEX, click on it to open the hex box. There you paste the hex string, at the top of the box is target with word DRAG next to it, once you have pasted the hex string you will press and hold the TARGET icon and drag it to a key, click on it to place it on the key. Now you can rename it or leave it with name they give it. You click save and download it to your remote and test.

I start with a clean slate, nothing programed in the remote?

No, you start with dedicated device for the DVR, is the mx-900 programmed for other devices you already have? This new device will be empty until you have imported hex and assigned them to keys of your choosing. Test one of the codes before doing all.

I only have mx-900 set to use the stand alone mx-900 editor because of you, and this question:

Previously I only programmed the mx-900's via CCP.

Now that you have the instructions, see if this hex works as the POWER function

Device Code: 128.255 Function: 10
0000 006D 0022 0002 0157 00AC 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0041 0015 0041 0015 0041 0015 0041 0015 0041 0015 0041 0015 0041 0015 0041 0015 0016 0015 0041 0015 0016 0015 0041 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0016 0015 0041 0015 0016 0015 0041 0015 0041 0015 0041 0015 0041 0015 0689 0157 0056 0015 0E94

Start w/ a clean slate and add a device for the DVR,
Open Universal Browser,
Click on Hex Editor,
C&P the Hex code,
Drag to that command button.

Is that correct?

BTW, it's not UEI it's URC;
https://www.urc-automation.com/product/mx-900/

It's a older remote, but it's still current.
.

We never said the MX was a UEI remote, we know it's not, that's why most of us are not experts with it.

Then what was this about?

He was advising that you buy a UEI universal remote, and he even pointed out that they're cheap.

Then I misunderstood. My bad.
I'll let you know about that code as soon as I get the DVR, the weather is delaying it.

It just dawned on me I posted the wrong DVR name. It should be Tablo, not Homeworx. OP corrected.
