BrightAuthor and RS232

Hi All, I am trying, with no success, to control a Sharp 60" TV via RS232 with an HD1010 and brightauthor. The power on command for the TV is "POWR1 " CR, with 3 trailing spaces after the "1". I have tried this RS232 command with another control system and it has worked fine. I'm wondering if, when sending the command, are the 3 trailing spaces dropped from the string? If so that might expalin why it hasnt worked. Anyone have any thoughts?

    Sharp TVs require a command to allow it to receive the RS232 "on" command.  Turn it on manually, then send "RSPW1_ _ _" (cr). This only needs to be done once.  If successful, the TV will then respond to POWR1 after that.

    I have occassionally experienced an anomaly that the TV wants "RSPW_ _ 1 _" (cr).  Can't explain why and I haven't found it documented anywhere.
    baud rate is 9600 and would need null modem cable between Player and TV.

    also,
    configure brightauthor interactive presentation to use: "Serial-send string (EOL) Port 0 String POWR1(three spaces)

    The EOL will send the carriage return

    Thanks for the replies.  I have sent the RSPW command already using another control system and I have configured the presentation to use send EOL but again with no success.

    if you can verify power-on success using hyperterminal (or other comm program), or your other control system, then I think you're right that BA must be dropping or doing something weird with the three spaces.  I think I would connect PC to player with null cable and use hyperterminal (or other comm) to monitor the characters that player is sending out when command is issued

    did you verify, in Presentation Properties, that "Send EOL" is set to "CR" (there are 3 possible selections but this is the one that works for me, at least with LG TVs).  Also double-check baud rate.

    I have verified that EOL is CR and with no LF and the baud rate is correct.  I will try and see what the actual output is by connecting to hyperterminal, thanks for the suggestion.

    Uptade.

    I got it woking. After verifying that the HD1010 was sending the correct strings, I did a factory reset on the TV and it worked.Strange I konw, but perhaps there was some setting on the TV that was changed that prevented it from working.
