hi I encountered a similar remote with mid-framebust and the reapeting frame is a lead in and one on, which is very similar to jiangsu.
It is a ocn es200 stb (shanghai ocn cable and model is longjing tech es200)
I uploaded the ict to diagnosis area here:
http://www.hifi-remote.com/forums/dload.php?action=file&file_id=14435
I noticed that not only one and zero defined in jiangsu are the same as those in ocn, device bytes of 3 and command byte of 2 are the same. Also, the starting bit of midframe burst is also the same after bit 24.
Can someone take a look at why this rmdu doesn't work?

It is modified from jiangsu protocol, so one will need to add jiangsu protocol to protocol.ini.
Before I tried to modify the jiangsu protocol, I actually used protocol builder to build a protocol with mid frame burst equaled to lead in frame. This is done with
BITS W7.3
JP $0146
But the resulting signal only has 1 signal (which is the same as the original learn) and no repeating signal, unlike the original signal with repeating (lead in, one on, silence)
I think that's why it doesn't work.
The modified jiangsu rmdu is really close imo, just the lead out silence is slightly different.
I don't know why it doesn't work.
Thanks, |

Basically it looks like it shoots the correct signals. However, the exact durations may be slightly wrong.
I'd try changing
Code: | 43 8B 32 8B 16 CF 44 08 08 01 11 02 12 01 11 00 FA D2 DC 07 1C 03 70 FF FF FF 19 77 77 F6 01 46 F6 01 0A 7B 01 AF E6 20 06 E6 21 E0 E6 28 C0 57 76 46 29 01 8D 01 46 |
Code: | 43 8B 32 8B 16 CF 44 08 08 01 11 02 12 01 11 00 FA D2 DC 06 FE 03 57 FF FF FF 19 77 77 F6 01 46 F6 01 0A 7B 01 AF E6 20 06 E6 21 E0 E6 28 C0 57 76 46 29 01 8D 01 46 | This will shorten up the durations of the lead in and mid frame burst. |

The above is the wave form of power button of the original remote.
The below one is that of the upgrade file modified from jiangsu protocol.
I know that the lead out silence and the silence after the first signal segment are different. Do they make the signal not work?
Or should I consider if the stb is hung or ir blaster not set up correctly?
It is a slingbox 500 so I doubt the ir blaster is not set up as 500 has built in ir emitters. |

For some reason, my friend to whom the ocn stb and sling box 500 belong, reported that the rmdu I posted above actually worked. Maybe he restarted the stb or something. Anyway, thanks. |
