Before Calling Customer Support
Check the following key areas to validate whether or not the DataShuttle is operational:
1. Make sure the AC Adapter is not damaged. To do this, detach the adapter from the DataShuttle,
while leaving it plugged in to the wall outlet. Then measure the voltage between the inside and
outside surfaces of the cylindrical connector. In this no-load condition, the voltage should measure
approximately 9V. If this is not the case, it is likely that the AC Adapter will need to be replaced.

2. Check the power section of the DataShuttle. After plugging the AC Adapter back into the
DataShuttle, check to make sure the LED is functioning. If the LED is not lighting up, then there is
likely a problem with the power section of the unit. Contact technical support for further
assistance.
3. Check the DataShuttle’s internal power supply. To do this, it is necessary to measure four voltage
terminals on the unit itself: the +5V and Vref(6.9V) terminals, found at opposite ends of the
terminal strip next to the passthrough connector, and the +15V and the -12V terminals, which can
be found on the raised section of the DataShuttle called the terminal board. (Please consult the
diagrams on pages 1–5 through 1–7 if you are unable to locate these terminals.)
If you have been installing resistors or capacitors on the analog input auxiliary section,
then it is necessary to remove the terminal board and re-check the +5V and Vref voltages. If, after
removal, these voltages return to normal, it is likely that there is a short-to-ground on the terminal
board. Check the resistor/capacitor installations for such a short and reinstall the board.
If removal does not fix the +5 and -12 voltages, then there is a problem with the DataShuttle’s
internal power supply. Contact technical support for further assistance.
