Front Panel
Power Switch
The Power button is on the far right side of the Interface 1000 Front Panel. It is a push-push switch: push once
to turn the instrument on and push again to turn the instrument off. The switch’s button latches: the button is
closer to the front panel when the instrument is on than when it is off.
Normally the Power LED illuminates when the Interface 1000 is powered on; see the Power LED description
below.
Normally, the DC power is connected before the Power button is turned ON. However, no damage occurs if
this switch is already in the ON position when the cable is connected to Power In, or when the AC power
input is connected to the external power supply.
The Power LED
The Power LED is on the lower right of the Interface 1000 front panel. It normally glows a continuous blue
when the Interface 1000 is turned on and has passed some simple power-on tests.
When the Interface 1000 is first turned on, the Power LED glows steadily for a second or two, blinks three
times, and then goes to its normal steady blue output.
When the Power LED is off, these are possible causes:
Caution: Avoid touching the Power switch button during normal instrument operation.
Data are lost if the instrument is accidentally powered off during an experiment.
The Interface 1000 uses three DIN connectors for connections to external devices. The three
DIN connectors all have different numbers of pins and physical sizes, so the cables used in them cannot be
interchanged or improperly connected.
