In the XML file, it indicates he wrote the manufacturer as "ShengZheng TianWei" and the model name as "DVTe 203A". After an extensive search this is the only information I was able to find regarding it.

Product Overview
DVTe-203A Series is our remote control for video design and development of Shenzhen Tianwei third-generation remote control. Using 8-bit FLASH MCU imported EEPROM can save the extra cost, to avoid the learning easy to flush EEPROM in the possibility of a fixed code.
More integrated, more stable performance.
Key Features
- Intelligent analysis - Just keep learning good waveform data, do not need to deposit a fixed code, the software automatically recognize all kinds of unknown format, learning success rate of 99.9%, several times before learning to avoid the hassle.
- Long guard - The data has never been set memory function, even in the absence of a battery, the time to learn good data would be lost
- Up to 14 learning keys - Up to 14 learning keys, to be completed by a variety of home appliances remote learning function, learning success rate of 99.9%.
- High integration - Single chip, the failure rate lower. Combined with the launch window to receive the window, use the more convenient.
- Low power consumption - Better than the national standard, low-voltage 1.75V
- EEPROM save overhead.

Thanks Eferz, "ShengZheng TianWei" it shall be
Rob, I took a stab at this with the 00 F8:3 protocol, I was going to try to do this with out requiring a protocol upgrade, but after looking at the timings I think I'm too far out of whack. What do you think, custom protocol?
Sample timings
Timings from xml
+3638 -1804 +392 -368 +392 -368 +392 -1358 +392 -368 +392 -1358 +392 -368 +392 -1358 +392 -368
Timings from 00f8:3
+3414 -1667 +433 -413 +433 -421 +433 -1286 +433 -421 +433 -1294 +406 -440 +433 -1294 +406 -440
I'm not exactly clear on how to do the protocols.ini to get it to use the built in version, althoug I did update the RDF's with protocol information.

My guess is that that is close enough.

I decided to take the easy way out and force an upgrade instead of dinking around with protocols.ini.

How do you force an upgrade vs. use protocols.ini?

Well all the slingboxes have 00f8:3 built in, so if I setup up something for the ShengZheng protocol in protocol.INI, I could have had a device upgrade that didn't require a protocol upgrade, saving 32 bytes. But that was the "close enough" protocol, and it might not have been close enough, so instead I created a very simple protocol that has the right timings and requires 32 byte upgrade. I really want to learn how to manipulate protocols.ini, but it seemed like too much work.

The problem is that the learns for "left" and "zero" were invalid. This could have been avoided by validating the learns during teaching process. Vicky was able make an educated guess for the appropriate values for "0" but there wasn't enough information for "left". I would recommend in going back to reteach them and validating them. Let us know when you are able to relearn it, so it can be decoded appropriately. |

When I looked at the signals I couldn't figure out any of these keys.
| Quote: | | It appears that zero, eight, Guide, Left, Up and Channel Down are not going to work. |
When Rob did the analysis he figured out eight, guide, and Channel Down, I guessed at the zero, and up, but the left learn is bad. There is not enough information there to even make a guess.
Make sure you try the zero,guide, up and channel down are working correctly.

Some of the incomplete learns had enough of the signal there for me to tell the OBC, even if the learn itself wouldn't have worked.

jkgtw, did you ever relearn the left arrow and check the other keys?
I'd really like to finish this upgrade.

I tried emailing jkgtw to get him to come back to this thread, but the email bounced back, so we've probably heard the last of him.

Thanks for following up with the response. I see the results for the missing button.
Name: Left
EFC: 031
Byte 1: 76
OBC: 69
Hex: 32 A2
There was just no way to guess that one based on the other information. Unlike UP which matched Channel UP and Channel Down which matched Down. A rudimentary guess was easy enough to fill in that gap. |
