AMX Programming Help

OK, So I've programmed AMX Axcess stuff in the past, but this Netlinx language is new to me. I've got 90% of it figured out, but I'm having trouble controlling my Extron Matrix Switcher. I have the original Axcess code which is working fine, but no matter what I do, I cant get it to work in netlinx. The serial TX light is lighting up when I send the signal to the switcher, and the RX light is lighting up right after that. However, I can't figure out how to see what the switcher is saying back to me, so I have no idea what its telling me.

Here's the Axcess Code that works.

---------------------------

SWITCHER=3

DEFINE_CALL 'SWITCHAUDIO' (I,O)
{
SEND_STRING SWITCHER,"ITOA(I)'*'ITOA(O)'$'"
}

DEFINE_CALL 'SWITCHVIDEO' (I,O)
{
SEND_STRING SWITCHER,"ITOA(I)'*'ITOA(O)'%'"
}


PUSH [TP,17]
{
CALL 'SWITCHAUDIO'(4,2)
CALL 'SWITCHVIDEO'(4,2)
}

-------------------------------

Anybody out there have suggestions?

Select Enable Netlinx Device Notification from the Diagnostics menu.

This will show send and receive data in the status window at the bottom of the screen.

Hi Jeff,

Your SEND_STRING statements need some additional commas to separate each character that make up the string you are sending.

e.g. Instead of

SEND_STRING SWITCHER,"ITOA(I)'*'ITOA(O)'$'"

you need to use

SEND_STRING SWITCHER,"ITOA(I),'*',ITOA(O),'$'"

Also your SWITCHER declaration should be a device declaration using the Device:Port:System specification.
