Looks like my Rivendell appliance machine just seems to disconnect the USB port and reconnect on another port.
Was watching the logs and it disconnected ttyUSB0 and then connected the GPI-16 to ttyUSB1.
They do that, unfortunately. If you do some Googling, you'll find out that there's a way to tell udev to assign a specific name to the device, such as /dev/btswitch, which you can use in RD regardless of whether it gets recognized as /dev/ttyUSB0 or /dev/ttyUSB1.
That said, what worked in Debian 6 doesn't necessarily work in Debian 7 as udev keeps getting played with by the developers.
Also, some USB-to-serial-port converters don't carry enough identifying information for udev to uniquely distinguish one from another.
At WCRI, I lost patience with this nonsense and installed an old fashioned serial port card.

Going to keep my eye on it. If there is someone that can dispense some advice on wiring a Broadcast Tooks SRC-4 output relay to a GPI-16 input, could you email me off list? I've got MediaTouch closing/opening the relay. GPI is not showing anything unless I physically ground the input pin to trigger the input. Finally learning this side of the business....

It would be fine for a few days and then would stop receiving via Riv. In the end I stopped using Rivendell as a go between and used screen combined with some shell scripts to relay to Riv via rmlsend. It has been reliable ever since. Its worth a try either way although it may not make a difference: http://rivendell.tryphon.org/wiki/Switchers#The_macros_didn.27t_work On 26/01/17 00:32, Steve Varholy wrote: > Ouch.
