HD1024 serial control problems

Hi

We are using a HD1024 player and a Panasonic TMZ400 projector. 

The player and projector are connected from the USB-A port on the player to the DB-9 RS-232 connector on the projector. It is an adapter cable I have used before without any problems.

I try to power ON and power OFF the projector but have NO succes at all.

I have tried to send with both ascii and binary protocols, but the projector does not react.

The Panasonic Power ON command is: [STX];PON;[ETX] but that does not work in ascii mode.

Then I have tried to send the decimal version 2,80,79,78,3, but that does not work either. (It did in fact work on another Panasonic projector)

I have also tried to send other commands with different protocols but no succes.

Do You have any ideas of what is wrong or suggestions?

Greetings

Steffen

    Hi Steffen,

    Which Serial command are you using in BrightAuthor?  There are a few to choose from:

    • Serial string (EOL)
    • Serial string (no EOL)
    • Serial byte
    • Serial bytes (comma separated)

    Also, check your serial port settings in the presentation to ensure they match what the projector is expecting for Baud rate, etc.  

    Panasonic Spec from the manual:

    • Sync. method: Asynchronous
    • Baud rate 9600 bps
    • Parity: none
    • Character length: 8 bits
    • Stop bit: 1 bit
    • X parameter: none
    • S parameter: none

    Transmission from the computer starts with STX, then the ID, command, parameter, and ETX are sent in this order.  Add parameters according to the details of the control.

    According to the manual, there is no semicolon between the command and the ETX.

    STX ; PON ETX

     

    Using USB for serial on a BrightSign will enumerate on Port 2 on the HD1024.  It will enumerate on Port 0 if you're using the 3.5mm serial jack.

    Serial devices connected to a USB port will enumerate on port 2 of the player (on the LS424 player, they will enumerate on port 0). Additional USB-serial devices will enumerate on ports 3, 4, 5, etc. The enumeration order will remain consistent between reboots as long as the USB-serial devices are connected to the same player/hub ports. The enumeration order can be retrieved using the "usblist" command at the brightsign> shell prompt; otherwise it will need to be determined by testing the setup.

     

    Alternative thought - CEC Commands

    I looked up this projector, and it does support CEC commands.  

    CEC Command-Compatible1 HDMI® Makes Life Easy

    Both of the projector’s HDMI inputs are compatible with CEC commands1 for your convenience. The projector will automatically switch on, select an input, play your content, and switch off when it detects these commands from a compatible source device such as a Blu-ray™ player, media streaming dongle, or Panasonic’s optional Wireless Presentation System PressIT2. Get your content playing smoothly and easily using just one remote control.

    Are you able to try sending a command via the HDMI for display on / display off versus over serial?

    The command can be found on the following path:
    BrightControl > Display On
    BrightControl > Display Off

    We have used this successfully with Epson and Optoma projectors, but have not attempted with a Panasonic projector yet.  Let us know if it responds to the CEC commands.

    Cheers,
    Monica

    Hi Monica

    Port 2 is exactly where the problem occurs, I can see :-) In Brightauthor it is as default port 0. I will try the new port and I am sure it works perfect now.

    Hi Steffen,

    Hooray!  Glad you were able to diagnose the issue.  Hope this thread helps others who may have the same problem in the future!  Let us know if changing the port solves your problem.

    Have a great day!

    Monica
