DCE-1: how to set RS-232 parity?

RedingReding Junior MemberPosts: 3

I like to control a Sony projector with parity even.

According to specifications of the DEC-1 the parity Odd/Even/None should be supported.
But I can't find a command in the API command list.

Is there anyone who knows this command or can help me to control a Sony projector with the DCE-1?

    Set the RS-232/422/485 port's communication parameters.
    NOTE: On NX-series controllers, ports 1&5 support RS-232, RS-422, or RS485. The three modes are mutually
    exclusive. Setting any of the three modes disables the other two.
    NOTE: The RS-232 ports on Massio ControlPads are RS-232 only, so sending the SEND_COMMAND to Enable 422 or 485 mode on a Massio ControlPad via Telnet will have no effect on the ControlPad, and the ControlPad will not
    return an error message.

    Syntax:
    SEND_COMMAND ,"'SET BAUD ,,, [422 Enable | 485 Enable]'"
    NOTE: Serial modes are mutually exclusive. RS-232 is specified by omitting 422 Enable and 485 Enable. Enabling
    422 effectively disables 232 and 485. Enabling 485 effectively disables 232 and 422.
    Variables:
    baud = baud rates are: 115200, 76800, 57600, 38400, 19200, 9600, 4800, 2400, 1200, 600, 300, 150.
    parity = N (none), O (odd), E (even), M (mark), S (space).
    data = 8 data bits.
    stop = 1 and 2 stop bits.
    422 Enable = Enables 422 (Disables 232/485)
    485 Enable = Enables 485 (Disables 232/422)
    NOTE: The only valid 9 bit combination is (baud),N,9,1.
    Example:
    SEND_COMMAND RS232_1,"'SET BAUD 115200,N,8,1 485 ENABLE'"
    Sets the RS232_1 port's communication parameters to 115,200 baud, no parity, 8 data bits, 1 stop bit, and enables RS-485 mode.

    Hi Chris

    Thank you for your response.
    My question is not about the Netlinx controller. It's about the DCE-1 In-Line controller:

    And i'm looking for an additional command to the baud rate command CUB#T on page 17 in this manual:

    My apologies. I have a question into the product manager and hope to circle back with a response.

    It's been a long time but now I know news. **Parity cannot be changed and is not supported. **The data sheet https://www.amx.com/en/product_documents/dce-1-datasheet-pdf online is not correct (As of Jan 11, 2023). And should be corrected by AMX...

    In Fact it is not possible to control an Sony Projector as an example.
