does anyone have the codes for the Toshiba HDDVD player?

Joe Hebert

Here is a thread at Remote Central that describes the RS-232 codes:

I'll post the text in case the thread goes AWOL in the future.

Here are RS232C Serial Commands for Toshiba's new HD DVD Player

Start code 0x45 and 0xB5

Example to send a pause code "00"
0x45,0xB5,0x00,0xFF

Example to send a Play code "15"
0x45,0xB5,0x15,0xEA

RS232C protocol:

9 pin male D connector DB9

pin 2 is receive
pin 3 is transmit
pin 5 is signal ground



start code: "45 + "B5"

what is the reversal function code and how do you determine it

Subtract the function code from 255 and you have the reversal function code.

thanks

thanks for the speedy response I gave this a quick try with no luck. I tried it as "$45$B5 etc
but I noticed it says the start command is four bytes, so "45 B5" in ascii translates to 8 bytes in hex, so the question is how do you read this

Joe Hebert

I haven?t got any experience with this unit so I can only venture a guess.

My first would be to try:
Play
SEND_STRING dvDVD, ?45B515EA?

If that doesn?t work then I would try:
Play
SEND_STRING dvDVD, ?$45,$B5,$15,$EA?

But since the description says 8 bytes for the command I?m leaning towards the first SEND_STRING. Do either of the above work?

Joe Hebert

Here is the correct string to send for PLAY and I can confirm it works:

SEND_STRING dvDVD,"$45,$B5,$15,$EA"

The protocol is somewhat misleading since it leads one to believe each command is 8 bytes long (which is obviously wrong and only 4 bytes)

Note: The discreet Power Off (code $93) does not work. Hopefully Toshiba will fix this in the future. So like the Hotel California, you can check out anytime you like but you can never leave.
