If one or more of the readings fails to be within range, it is likely that there has been a
failure of the either or both of the DACs and their associated circuitry on the motherboard.
Status Outputs (Digital Output Pins 1 – 8)
To test the status output electronics:
1. Connect a jumper between the "D" pin and the "" pin on the status output
connector.
2. Connect a 1000 ohm resistor between the "+" pin and the pin for the status
output that is being tested.
3. Connect a voltmeter between the "" pin and the pin of the output being tested
(see table below).
4. Under the Utilities>Diagnostics menu scroll to the output in question.
5. Alternately turn on and off the output noting the voltage on the voltmeter.
