    Re: Extron Module SW-VGA Ars - CSD for VA

    Hello,

    I am sending the following string:

    Input 1 to Output 1. (1!) Or (31 21)
    Input 2 to Output 1. (2!) Or (32 21)
    Input 2 to Output 1. (3!) Or (33 21)
    Input 2 to Output 1. (4!) Or (34 21)

    Do not know if I need some argument in the string, or should I send in ascii or hex.

    Thanks for your help,

    That's definitely the correct protocol for the Extron switchers.

    Just to confirm you are sending it as
    send_string dvYourDevice, '1!'
    



    If you are pulling the input from a numerical variable you will need to also make sure that you convert it to its ascii representation:
    integer input = 1
    
    ...
    
    send_string dvYourDevice, "itoa(input), '!'"

    Hello,

    As I am working in VA, CSM attached image where I am assigning a master controller strin, when I compile and upload the code, to activate the function in the TP indicardor shows no activity on the serial port and does not change the input on the Extron .

    Thank you for your comments,

    Try adding a carriage return - $0D to your string or verify it is being added in VA.

    Can be set "Include Terminator" to False in tab "Packet format".
    or
    Enclose the value in quotes: '1!'
    In NetLinx: SEND_STRING Extron, " '1!' "

    from the instruction:
    Host-to-switcher instructions
    The switcher accepts SIS (Simple Instruction Set) commands through either serial port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence.
