The USB LED is unlit when:
The Interface 1000 is not powered.
The Interface 1000 does not have a USB cable plugged into its rear-panel USB port.
The computer end of the USB cable is not plugged into a USB port on a computer or hub.
The USB cable is not supplying USB power to the Interface 1000.
The computer has disabled the USB port going to the Interface 1000.
The USB LED glows a continuous green if a valid USB connection is made and the Interface 1000's
communication processor receives power along the USB cable.
The USB LED flashes orange whenever the Interface 1000 receives or transmits valid USB messages to or from
the host computer. It does not flash if there is USB traffic addressed to other devices on the USB bus, including
messages aimed at a different Interface 1000.
The USB LED indicates a continuous red in one special condition: when a firmware update occurs. Interrupting
a firmware update can cause a catastrophic failure of your system. Do not turn off the Interface 1000, do not
unplug the USB cable, and do not stop the operation of the host computer when the USB LED is a
continuous red color.
Caution: Do not interrupt a firmware update while it is in progress. An incomplete update
can render an Interface 1000 inoperable until it is returned to Gamry for reprogramming.
Cell On LED
The Cell On LED is to the left of the Cell Cable connector.
The Cell On LED glows yellow whenever the Interface 1000 is actively applying voltage or current to the
electrochemical cell attached to the Cell Cable. Avoid touching the cell cable leads whenever the Cell On LED
is lit, because the quality of the data being collected in your experiment may be compromised.
The Cell On LED does not indicate a dangerous condition when it is lighted. The voltages
generated by the Interface 1000 are generally considered safe. Still, avoid touching the cell leads when the
cell is on.
