If a panel contains more than one Edge Computer (752-9800) it might be useful to make the one you are working on to emit a beep. This can prevent accidentally interacting with the wrong devices, etc.
- ssh to the device and type
apt-get update
- type:
apt-get install beep
- To make the device beep, for example type:
beep -f 300.7 -r 10 -d 100 -l 400
- See the documentation on beep to change the frequency and duration of the beep.
