Channel Master DVR+

rhsmsg · Post by **rhsmsg** » Sat Jan 02, 2016 10:56 am

1. Device: Channel Master DVR+ CM-7500GB16
2. Type of device: DVR
3. Year: 2015
4. JP1/UEI Remote model: URC-8811 8K Extender3
5. Do you have a JP1 cable? Yes
6. Still have original remote? Yes
7. Checked the file section? Yes
8. Checked Pronto file section (at R/C)? Yes. R/C search found ccp file for the learned codes but download doesn't work.
9. Partially working setup code? No
10. Learning remote question?

I am looking for a Channel Master DVR+ upgrade. I learned three keys from the Channel Master DVR+ remote
and verified the learnt keys controlled the DVR+. I downloaded RMIR and it showed the learned protocol as NEC1-rnc
but the RM protocol list does not include NEC1-rnc.

I found this thread showing the OBC's: https://www.remotecentral.com/cgi-bin/m ... .cgi?27602

I read "How Do You Create An Upgrade From Scratch?". I don't have KM but it looks doable if JP1 supports the NEC1-rnc protocol?

11. Have you tried the JP1 Lookup Tool? Yes, didn't find anything
12. If you have a Nevo (or similar) remote, have you tried ez-rc.com? n/a

This protocol hasn't been added to RM yet (and won't ever be added to KM).

Here is my best guess as to the new entry that would be required in protocols.ini :

Code: Select all

[NEC1-rnc]
PID=02 06
AlternatePID=01 E3
CmdTranslator=Translator(lsb,comp)
CmdParms=OBC=0
DevParms=Device:8=0,Sub Device:8=[-0]
DeviceTranslator=Translator(comp,lsb,0,8,0) Translator(comp,lsb,1,8,8)
FixedData=ff 00
Notes=NEC1-rnc is similar to NEC1, except the nibbles of the command complement are reversed.
Code.S3C80=43 8b 21 8b 12 cf 4d 08 08 01 21 03 30 01 21 00 fd d2 dc 11 94 08 b6 20 11 e4 05 06 60 06 f0 06 8d 01 46

Here's the RMDU file. This hasn't been tested, so please report back if it works.

Here's a protocols.ini entry which shoots the correct signals as verified with a Widget. The PID 0206 executor, like other newer executors from UEI, doesn't want the "comp" part of the translators. I've also left out the Alternate PID line, because 01E3 is in use by UEI.

Code: Select all

[NEC1-rnc]
PID=02 06
DevParms=Device:8=1,Sub Device:8=[-0]
DeviceTranslator=Translator(lsb,0,8,0) Translator(lsb,1,8,8)
CmdTranslator=Translator(lsb)
CmdParms=OBC=0
FixedData=80 7F
Code.S3C80=43 8b 21 8b 12 cf 4d 08 08 01 21 03 30 01 21 00 fd d2 dc 11 94 08 b6 20 11 e4 05 06 60 06 f0 06 8d 01 46
Code.MAXQ610=33 69 21 0E 16 00 3F 00 16 00 15 00 05 10 56 01 AB 00 00 80 08 17 D3 D2 FF 51 D3 D3 00 62 D4 04 70 71 72 73
Notes=NEC1-rnc is similar to NEC1, except the nibbles of the OBC complement are reversed.

Note that the upgrade Rob posted will shoot the complement of the needed OBCs, I think. I guess you'll need to make an upgrade file with the correct OBCs.

Ah, I didn't notice that UEI didn't use the complement like they normally do.

If you don't give it an Alternate PID, you can't use the executor in older remotes, like the URC-8811 that rhsmsg has, and Slingboxes, etc. So by all means pick a different PID but it does need one.

I have updated the RMDU file.

I edited the protocols.ini file in the RMRMIR folder with notepad, adding the executor lines and the untested version 2 rmdu opened sucessfully with RM. RMIR wouldn't download my remote using my parallel or usb interface, so I used IR V8.04 with my parallel interface.

All the rmdu Functions work ok and the list looks complete.

Thanks for your help,
Robert

That is probably because of the issue being investigated here:

Godo to know, thanks.

Just to let everyone know that a user on the Slingbox forum has proven this works with the new Channel Master box.
