in AMX Hardware
I m not able to control the extron switcher thru the amx touch panel.

The rs 232 is working because thru notifications i can send and recieve the messages

i have defined the device

dvExtron =5001:2:0
dvTpExtronMVP7500 =10001:2:1

and my extron code is


PROGRAM_NAME='IncExtron'

DEFINE_VARIABLE

INTEGER Index

char Sbuff[40]

INTEGER nExtronbutton[] =
{
1,2,3,4, // VGA

5,6,7,8, // S- video

9,10,11,12 //video


}


DEFINE_START

create_buffer dvExtron,Sbuff

DEFINE_EVENT

DATA_EVENT[dvExtron]
{
online:
{
// Set Baud for Projector
send_command dvExtron,"'SET BAUD 9600,N,8,1'"
}
}


BUTTON_EVENT[dvTpExtronMVP7500,nExtronbutton]
{
push:
{
Index = GET_LAST(nExtronbutton)
SWITCH(Index)
{
CASE 1:
{
// VGA
send_string dvExtron,"'1!'"
break
}
CASE 2:
{
// VGA
send_string dvExtron,"'2!'"
break
}
CASE 3:
{
// VGA
send_string dvExtron,"'3!'"
break
}
CASE 4:
{
// VGA
send_string dvExtron,"'4!'"
break
}
CASE 5:
{
// S-video
send_string dvExtron,"'5!'"
break
}
CASE 6:
{
// S-video
send_string dvExtron,"'6!'"
break
}
CASE 7:
{
// S-video
send_string dvExtron,"'7!'"
break
}
CASE 8:
{
// S-video
send_string dvExtron,"'8!'"
break
}
CASE 9:
{
// video
send_string dvExtron,"'9!'"
break
}
CASE 10:
{
// video
send_string dvExtron,"'10!'"
break
}
CASE 11:
{
// video
send_string dvExtron,"'11!'"
break
}
CASE 12:
{
// video
send_string dvExtron,"'12!'"
break
}
}
}
}

i think the code i m sending to the extron switcher is not recognized by it

can anyone help me in this ,this is my first program.

    I think you need to put a CR and/or LF at the end of the string


    example
    CASE 1:
{ 
// VGA
send_string dvExtron," '1!',$0d,$0a "
break
}

    Double check that your port actually went to 9600. Send a command to the port with control a device in diagnostics. The command is GET BAUD. Every once in a while, even when the processor says the port is online, It's not ready to receive a SEND_COMMAND. Extron commands don't need a CRLF.

    Make sure it's in single-switcher mode by sending 1*1# (or via front panel config). Then it should switch via the 1! commands.

    It may also be necessary to put a CHARD command on that port. As I recall, the unit is really only looking for single bytes, and if they come in too fast it may not recognize the command.

    the extron switcher was not in the single switcher mode ,so once i change it to single mode.the extron started recognizing the commands thru rs 232

    thanks to all for your help

    Really? Is this a known documented bug? Has AMX confirmed this issue and are they working on a fix?

    Does this problem exist for SEND_COMMANDs to any device in its ONLINE: handler or is it strictly an RS-232 port problem?

    I never reported this as a bug. It happens so sporadically I never thought to follow thru with it... Ajay just needs to confirm that the port actually changed to the proper settings.
