The Door Lock
2013-06-19: Door Relay was upgraded to a KMtronic Two Channel USB Relay Controller.
Relay interface uses a baud rate of 9600. Valid commands include (in hex, without spaces):
- "FF 01 00": Turn relay 01 OFF
- "FF 01 01": Turn relay 01 ON
- "FF 01 03": Retrieve relay 01 state. Returns "FF 01 00" for off, "FF 01 01" for on.
- "FF 02 XX": Same as above, but for relay 02.
Commands can be sent from the command line via echo -e "\xff\x01\x01" > /dev/ttyUSB0. The script merlo:/root/readrelay.sh retrieves and echoes the state of relay 01. Full documentation is available on the KMtronic site. See Manuals and Software Examples for more information. The manual for this relay controller and fully functional shell script examples are available at http://www.ucc.asn.au/~door/kmtronic/
The Depths of Time
Hi All, The modem has now been replaced with the arduino and the small 5v relay board. It's working for now, but it's a hack and not even properly boxed up.

Fixing the door lock
Symptom: Cries of "The door's broken." Door relay doesn't activate from snack machine, dispense or serial from Merlo.
Cause: The seeduino program seems to hang.
Fix: Restart seeduino (unplug/replug), then restart vendserver.
