4.10 DACview
DACview is a troubleshooting aid that allows
access to internal readings. The feature allows
output voltage, current and power that the system
reads to be output to a DVM or oscilloscope.
To use DACview, the system must be in the Test
Mode.
1) Set the system for operation in Test Mode as
described in the preceding section.
2) Connect a DVM to the Control Board test
points labeled TP7 – DAC_VIEW and TP6
– AGND.
3) Turn the power on and press the PC key until
the Test Tones begin.
4) Move the DACview switch (S2 position 8
– the change is recognized, not whether the
switch is on or off).
5) The Monopolar Cut Power Digital Display is
used to display the selected DACview chan-
nel. Since power was just initialized, the
Monopolar Cut Power Digital Display will
display “0” at this point. Select the desired
channel using the Monopolar Cut Power
Adjustment Keys.
6) Move the DACview switch (again, the change
is recognized, not whether the switch is on or
off). The cut power setting will be displayed.
7) To select a different location to monitor with
a DVM, simply move the DACview switch
and the memory locations will be displayed
instead of the cut power. Select the desired
selection and then move the DACview switch
again.
