Probe Status & Alarm LED’s:
Commander operates by sensing the number and location of probes upon power up. Those ports
with sensor probes connected will be indicated on the front panel. Commander has one direct
USB port but can sense up to 4 probes using a USB hub. The Alarm Sensor will reflect the
condition of any of the probes.
If Commander is powered on and a new probe is plugged in, Commander will sense the new
probe and acknowledge its existence. Probes can be installed or removed without having to power
down Commander. When installing or removing probes, perform a browser refresh.
