Sharp Bluray 232 protocol

I'm guessing he was referring to the 232 port on the Sharp.

Thanks for the tip. I bet that was a fun problem to track down.

Useful tip for anyone trying to control a Sharp BD-HP50 or BD-HP70.

Do NOT use $0A at the end of the command string. It will lock up the COM port, though not right away. The only way to get the com port to work again is by pulling power.

So please disregard this helpful nugget in Sharp's protocol manual:


Thanks Sharp!

This is odd. We've done two Sharp blu-ray players recently and both work with crlf (i.e. 13, 10) as terminator. These things are fussy, In both cases, they stopped responding to RS232 during setup. It seemed to be when the guys with the screwdrivers and soldering irons were playing around with the IR remote while trying to traverse menus using RS232 commands. In both cases, hard power cycling (removing ac power) brought the units back. Cycling with the power button didn't do it.

I'd like to avoid these things in the future -- is there a comparably priced unit with RS232 by anybody else?

No idea of your target price, but Pioneer's BD's control well. I am working with a BDP-33FD now.

Even though components used in the Theta version are most likely better it still speaks to the quality of Oppo being related to Theta.

You say that, but....

Lexicon took a BDP83, pulled the front, rear, and top panels off, and then dropped it in their own case.

I had to actually do a firmware upgrade to get RS232 communcation active.

Does anyone have any advanced command strings beyond the basics
listed in the owners manual (ie: requests, IR remote keys, etc)?

Thanks

I ran into the lack of these commands about a year ago on a BD-HP50U. I noticed that every command seemed to be 'D*** ',$0D, but when I called sharp they were unable to provide specifics on what other commands were available. So I wrote a quick program that would send a command every second to the sharp, and if it responded with 'OK' I logged it, then I sent everything from DAAA to DZZZ and kept a record of what came back. Then I went to lunch.

Something like two hours later, I ended up with this list

DAKY
DANG
DAUD
DBKY
DCKY
DCLR
DDKY
DDSP
DDWN
DEJT
DENT
DEXT
DFNC
DFWD
DLFT
DLGT
DPGN
DPGP
DPIP
DPLY
DPMN
DPUS
DREP
DRET
DREV
DRGT
DRPL
DRPO
DSBT
DSET
DSKB
DSKF
DSKS
DSTP
DTMN
DUPK

The ones I ended up using were

DPLY - Play
DSTP - Stop
DPUS - Pause
DSKF - Next (Skip Forward)
DSKB - Back (Skip Back)
DREV - Rewind
DFWD - Fast Forward
POWR1 - Power on
POWR0 - Power off
DTMN - Disc Menu
DPMN - Popup Menu
DUPK - Up
DDWN - Down
DRGT - Right
DLFT - Left
DENT - OK (Enter)

I don't know what the rest of them do but I hope this gives you a good place to start
