PCA DIAGNOSTIC (D435)
This diagnostic can test the HP 30050A Universal Interface (TTL) PCA, HP 30051A Universal
Interface (Differential) PCA, or the HP 30219A Card Reader Punch Interface PCA. The diagnostic
requires the HP 30049C Diagnostic Hardware assembly to execute the diagnostic. The following
procedure is used to verify operation.
OPERATOR ACTION/COMMENTS
CONSOLE MESSAGES
Set the SYSTEM DC POWER switch to STANDBY. Discon-
nect the cable for the peripheral device from the PCA to be
tested.
Remove the PCA to be tested from the card cage and note the
position of the interrupt jumper. If a TTL PCA, also note the
presence or absence of jumper WI (present = positive true,
absent = negative true).
The interface PCA must have a jumper inserted near con-
nector J3. If the jumper is missing, remove the two-pin
jumper plug from the Diagnostic Hardware assembly and
insert it near J3 on the interface PCA. This jumper provides
power to the Diagnostic Hardware assembly.
Insert the PCA to be tested into the card cage.
Connect the Diagnostic Hardware Assembly to the interface
PCA.
Set the SYSTEM DC POWER switch to ON. The PWR ON
indicator on the Diagnostic Hardware assembly should light.
