If the door sensors die:
- On Mussel, as root:
/etc/init.d/uccdoors stop /etc/init.d/latd restart /etc/init.d/uccdoors start
- On Madako, as root:
moprc -i eth0.2 janus <enter password> <enter username (UCC)> set priv <enter privilege password> init del 0
Not all these steps may be necessary - often, resetting the DECterm (second item above) will do the trick.
Some tricks and lessons learned
- The door solenoid requires a fair bit of power, the huge power supply in the machine room is huge because it needs to be. Don't try and substitute it with a wall wart.
- Similarly, the door solenoid struggles for power when you try and power it with only 2 of the 4 wires. Instead, connect 2 wires to each terminal.
- The modem takes 12V, so does the solenoid - don't try giving it 9V, it doesn't like it
- To test if you have connectivity to the modem:
- From mussel:
llogin door -w-
- Enter the password
- From here you can send characters to the modem (they won't come up on the screen though)
- Watch the lights on the front of the modem, one of them should turn on and flicker when you're sending data
- To manually open the door over serial type ATH1F (case sensitive) and hit enter
