When I've had to deal with devices Rivendell doesn't support, I've written a script outside of Rivendell that monitors the serial port, and, when it detects the closure, executes an rmlsend command to Rivendell.

Rivendell is not configured to look at the serial port at all, but only responds to the rmlsend command.

Hi all,

I was trying to get RDAirPlay 3.6.5 to work with a Broadcast Tools GPIO to
serial device model SRC-4.  I was unable to make it work so as part of
troubleshooting I decided to experiment with using a modem control line as
GPI.

I got started using the super-helpful post:

http://wiki.rivendellaudio.org/index.php/Serial_Port_/_Modem_Control_Lines_as_GPIO

I see the GPI 1 indicator in GPIMon 3.6.5 illuminate green when I supply
voltage to pins 5 and 6 on the serial port, so far so good.

I have a macro cart with the command PP S1 1 1 1!.  This is the string to
play the audio cart loaded in the top left corner of the Sound Panel.  If
I run the macro cart from RDLibrary 3.6.5 it works like a champ and the
tone plays.  Next I wanted to see if I can get it play upon activating the
GPI.

I went to RDAdmin-->Manage Host-->Edit-->Switchers GPIO-->Edit-->Configure
GPI, selected GPI 001 -->Edit.  For the "ON Transition" I selected the
macro cart.  I also put the same thing in for the "OFF Transition".

I closed everything out and tested but it's still a no-go.  I think
there's is something simple I'm missing here, (maybe enabling the feature
or a permissions issue) but I don't know what...any advice is greatly
appreciated.

Thanks,

Wayne
