Overview
Probe Adapter Loading. Any electrical connection to your system
adds an additional ac and dc load. The probe adapter was carefully
designed to add a minimum load to your system. However, this
additional load may affect the operation of the 88110 microprocessor in
systems with extremely tight timing margins. Appendix C contains
specifications on how the probe adapter affects your system.
88110 System and Probe Adapter Cooling. You must be sure to retain
the original level of cooling for your 88110 system after you install the
probe adapter. To maintain the required operating temperature, you may
need to provide additional cooling for the probe adapter.

INSTALLING SOFTWARE
Before installing the microprocessor application software, you should
be aware that there are three different versions of DAS 9200 system
software: the 9201T version, the 92XTerm version, and the 9202XT
version. The 9201T version allows you to operate the DAS 9200 from a
9201T terminal. The 92XTerm version allows you to operate the
DAS 9200 in an X window on a workstation. The 9202XT version
allows you to operate the DAS 9200 in an X window on a 9202XT
terminal.
NOTE
To use the microprocessor support package, you must
install application software that is compatible with your
DAS 9200 mainframe configuration and system software.
Two floppy disks are shipped with the 92DM923 support. To determine
which floppy disk contains compatible application software, follow
these steps:
1. Note the terminal type that will display the DAS 9200 user
interface.
2. Power on the DAS 9200 mainframe or system, and press the
Select Menu key.
3. Select the HW/SW Version menu in the Utilities menu column,
and press Return.
4. Look at the System Software line to find the version of system
software loaded. Use Table 2-1 to choose the correct floppy disk
to install. If your system software is an older version than the one
listed in the table, you should update your system software before
installing the application.

If you have any two types of DAS 9200 system software,
(9201T, 92XTerm, 9202XT), and you switch between the two, you
must install compatible application software on each system.
If you try to install application software onto an incompatible system or
terminal using DAS 9200 System Software Release 3, V1.1 or greater,
an error message displays.
If you try to install application software onto an incompatible system or
terminal using DAS 9200 System Software Release 3, V1.0 or lower,
the system will install the software but it will not operate properly when
you try to use it.
Install the disassembler software onto the DAS 9200 as follows:
1. Power up the DAS 9200 mainframe.
2. Insert the appropriate disk into the DAS 9200’s floppy drive.
3. Press the Select Menu key, and select the Disk Services menu.
4. Select Install Application in the Operation field of the menu.
5. Press F8: EXECUTE OPERATION, and follow the on-screen
prompts.
NOTE
After each install and load operation, a message appears
on the screen informing you the operation succeeded or
failed. If the message tells you the operation failed, you
may need to remove applications or files from the hard disk
and try installing or loading again. If the operation fails
again, refer to Appendix A: Error Messages and
Disassembly Problems.

Installation and Connections
CONFIGURING THE DAS 9200
To acquire data from an 88110 microprocessor, two 92A96 Modules are
required. They must be configured into one variable-width module.
When using a variable-width module, both 92A96 Modules must be
positioned in adjacent DAS 9200 slots. The module in the
higher-numbered slot is referred to as the HI module; the module in the
lower-numbered slot is referred to as the LO module. You cannot use
slots 1 or 8 when creating a variable-width module. The modules do not
need to have the same memory depth.
You should check the System Configuration menu to verify that the
variable-width module is defined correctly. Figure 2-1 shows how the
Sys Config menu looks when two 92A96 Modules are combined into a
variable-width module.
Probe connections on the probe adapter board are labeled to identify
which module and which probe group connects to them. For example,
LO_A0 indicates the A0 group from the LO Module.
Figure 2-1. Sys Config menu with a variable–width module defined.
Refer to your module user manual for additional information about
variable-width modules, connecting probe cables, and positioning and
installing 92A96 Modules.

Installation and Connections
In a system with multiple modules, it is easier to identify which
modules are connected to the probe adapter if slot number labels are
applied to the 92A96 probe interface housings and DAS 9200
mainframe. Figure 2-2 shows how to apply slot number labels.
Apply slot number labels here.
Figure 2-2. Applying slot number labels.
CONFIGURING THE PROBE ADAPTER
You need to set a jumper on the probe adapter before connecting the
probe adapter to the SUT. This jumper can be used to disable the
microprocessor’s internal cache by pulling the DBUG pin to an active
low state.
The normal position does not pull the DBUG pin low. DBUG position
pulls the signal low. If the jumper is placed in the debug position the
DBUG pin should be disconnected from the user SUT. You can
disconnect the DBUG pin by removing the W6 pin from the sacrifice
socket.

Installation and Connections
CONNECTING TO THE SYSTEM UNDER TEST
Before you connect to the SUT, you must connect the standard probes
to the 92A96 Module card. Your SUT must also have a minimum
amount of clear space surrounding the microprocessor to accommodate
the probe adapter. Refer to Appendix C: Service Information for the
required clearances.
To connect the DAS 9200 to the SUT, do the following:
1. Turn off power to your SUT. It is not necessary to turn off power
to the DAS 9200.
CAUTION
Static discharge can damage the microprocessor, the probe
adapter, the podlets, or the 92A96 Module. To prevent
static damage, handle the microprocessor only in a
static-free environment.
Always wear a grounding wrist strap or similar device
while handling the microprocessor and probe adapter.
2. To discharge your stored static electricity, touch the ground jack
located on the back of the DAS 9200. Then, touch any of the
ground pins of the probe adapter to discharge stored static
electricity from the probe adapter.
3. Place the probe adapter onto the antistatic shipping foam to
support the probe as shown Figure 2-3. This prevents the circuit
board from flexing and the socket pins from bending.
4. Remove the 88110 microprocessor from your SUT.
5. Line up the pin A1 indicator on the microprocessor with the pin
A1 indicator on the probe adapter board.
CAUTION
Failure to correctly place the microprocessor into the
probe adapter may permanently damage the
microprocessor once power is applied.
6. Place the microprocessor into the probe adapter as shown in

8. Line up the pin A1 indicator on the probe adapter board with the
pin A1 indicator on your SUT.
9. Place the probe adapter onto the SUT as shown in Figure 2-5.
NOTE
You may need to stack one or more replacement sockets
between the SUT and the probe adapter to provide
sufficient vertical clearance from adjacent components.
However, keep in mind this may increase loading, which
can reduce the electrical performance of your probe
adapter.
