Vidpro EBRA-121R remote controlled pan and tilt head.

Hi to all. This link is to the file I posted in the diagnostic area.

http://www.hifi-remote.com/forums/dload ... le_id=5478

This pan and tilt head is pretty inexpensive ($80-$99). It fits on a tripod and holds a camcorder. The remote, in addition to the pan and tilt commands, has a switch to pick one of three brands of camcorders (Sony, Canon, Panasonic) to control the zoom. Basically, this file has the up and down keys for the tilt, and the left and right keys for the pan. The stop key is for the auto-pan/stop function. The vol up and down are for the zoom in and out (I used Canon). They already have the Canon codes decoded. I don't have Excel or I would take a stab at using Protocol Decoder (I tried it with Open Office but the macros won't work). Thank you in advance for all your help and I look forward to more contributions to this great forum!

I just read in an old post that multiple protocols won't work with slingbox. If I could get a decode of the panhead file without the Canon stuff I would be one happy guy. Thanks.

Here's some info that might help someone with PB...

Isn't there an option in the IR engine to say that every bit in the command should be doubled (ie, follow each 1 with another 1 and each 0 with another 0), which would let you reduce the OBC to 6 bits.

I think there's also an option that would let you follow each 0 with a 1 in the device code bytes.

Thank you Rob and binky. Would it be possible to post this as an RM file? I need to make a bin for slingplayer and I'm having trouble translating it. Thanks!

binky123 · Post by **binky123** » Mon Mar 24, 2008 5:58 pm

You should be able to edit RM's protocols.ini and add

Code: Select all

[VidPro]
PID=01 A3
FixedData=55 50
Code.S3C80=3B 80 22 8B 15 8A 01 08 08 03 0C 00 F0 01 04 02 F8 1C 84 FF FF FF FF 04 FF 05 8D 01 46

and you should then be able to select this protocol.

Thanks binky. I edited the ini file and plugged in the button codes. Not working. Are there protocol parameters I need to add? Sorry - I'm new to this.

The function codes are what I listed in my previous post. I also had a sample device upgrade that I used to test with. When you say it doesn't work. Can you provide more details? At what step is it failing? Once you have an RMDU file, you have to export the Slingbox BIN file. After that, you have to insert it into the slingbox and then select that remote type from the Sling UI.

Hi. I exported the bin file to the slingbox. I get the remote with the five function buttons. Clicking on the buttons sends a signal but no response from the Vidpro. Please check my Rmdu file. I posted it here:

Thanks!

ok, the Fixed Data was not set in your RMDU file. In the Device 0: box, put 85. In the Device 1: box, put in 80. In the Fixed Data box, you should now see 55 50 appear. This should generate the correct device upgrade with the 55 50 bytes in it followed by the function code bytes.

Thanks - It works! I had a feeling I left something out. This opens up a lot of possibilites for remote device control. Thanks again.

Following Rob's suggestions on bit doubling, I went back into PB and generated this:

Code: Select all

1010 1010 1010 1100 1111 1111 stop  - BC
1010 1010 1010 1111 0011 1111 right - DC
1010 1010 1010 1111 1100 1111 left  - EC
1010 1010 1010 1111 1111 0011 up    - F4
1010 1010 1010 1111 1111 1100 down  - F8

freq: 41.8khz
Fixed Dev Data: 6 bits - FC 
Dev Bit Doubling: '0' after every '1' bit
Var Data: 6 bits 
Cmd Bit Doubling: Double every bit
1: +520 -1560
0: +1560 -520
LI: n/a
LO: 16120
LO as total: NO
LO: 2 = [OneOn, -LO]

Upgrade protocol 0 = 01 A3 (S3C8+) Custom Protocol for Vidpro EBRA-121R
 3B 80 11 8B 0F 85 C1 0D 06 06 01 04 02 F8 03 0C 
 00 F0 1F 7C 8D 01 46 
End

Upgrade Code 0 = 0C 2C (CBL/1068) Vidpro EBRA-121R
A3 00 61 FC BC DC EC F4 F8
End

That looks neat - nice and minimal. How would I translate it into an rmdu file? Protocol.ini looks the same. Again, I'm stuck on the parameters - fixed data, etc. Thanks.

binky123 · Post by **binky123** » Wed Mar 26, 2008 6:30 pm

You should be able to do the same. Edit protocols.ini:

Code: Select all

[VidPro]
PID=01 A3
FixedData=FC
Code.S3C80= 3B 80 11 8B 0F 85 C1 0D 06 06 01 04 02 F8 03 0C 00 F0 1F 7C 8D 01 46

The line is shorter than the previous one.

Then in RM, set device 0: 252 so that Fixed Data: FC. Function codes are 1 byte as listed above: BC, DC, EC, F4, F8.
