Plug-in Modules Not Recognized by the DCA Mainframe
fails to completely boot up leaving just the splash screen and the DCA buttons displayed.
Rebooting the DCA fixes the problem. If the DCA boots up properly, the problem will not
appear again.
Installing a PLD header plug on a connector on the A13 Acquisition Assembly can solve the
PLD lockup problem as described in
“A13 Acquisition Board PLD Header Modification
Plug-in Modules Not Recognized by the DCA Mainframe
Service Note 86100A-04
Serial Numbers below US4017:
On early 86100A mainframes, some modules are not recognized by the DCA. Usually the prob-
lem occurs when a clock recovery module is installed together with another module.
Various modifications were performed on the A13 Acquisition board assembly to solve this
problem. The modifications are not possible in the field.
To determine whether the A13 Acquisition board assembly has been modified, remove it from
the mainframe and examine U55 (see
). If U55 is a Motorola part, the board assembly
has not been modified and must be replaced.
Figure 6-17. U55 location
Replace the entire A13 Acquisition board assembly with the A13 exchange assembly. DCAs
with option 001 (divided trigger) will need to have the option 001 replacement assembly. Look at
the serial tag on the rear panel to see if option 001 is installed.
Refer to
“To Replace the A13 Acquisition and 86100C A14 Counter Assembly (Option 001)” on
as applicable.
Module Communication Error/Modules Not Recognized by the
Mainframe
Service Note 86100A-06
Serial Numbers: All
The clock line to the two modules does not have adequate isolation so reflections sometimes
cause errors in read and write operations. The symptoms are that the modules are intermittently
not recognized by the mainframe and that occasionally a module communications error is dis-
played on the DCA.
Solution: Replace the A12 Distribution Assembly with the preferred replacement, Agilent Part
number 86100-66518.
Refer to “To Replace the A12 Distribution Assembly” on page 7-42
