Overview
REQUIREMENTS AND RESTRICTIONS
This section describes requirements and restrictions of the digital signal
processor support product.
Probe Adapter Clearance. Your DSP3210 system must have a
minimum amount of clear space surrounding the DSP3210 digital
signal processor to accommodate the probe adapter. Figure C-3 in
Appendix C: Service Information gives these dimensions.
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 DSP3210 digital signal
processor in systems with extremely tight timing margins.
DSP3210 System and Probe Adapter Cooling. You must be sure to
retain the original level of cooling for your DSP3210 system after you
install the probe adapter. To maintain the required operating
temperature, you may need to provide additional cooling for the probe
adapter.

Section 2: INSTALLATION AND CONNECTIONS
This section describes how to do the following:
S
install the application software onto the hard disk
S
configure the DAS 9200
S
configure the probe adapter
S
connect the DAS 9200 to the SUT (system under test)
INSTALLING SOFTWARE
Before installing the digital signal processor application software, you
should be aware that there are three different versions of DAS 9200
system software: the 9201T version, the 92XTerm, 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 from a 9202XT
terminal.
NOTE
To use the digital signal processor support package, you
must install application software that is compatible with
your DAS 9200 mainframe configuration and system
software.
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 application software onto the DAS 9200 as follows:
1. Power on 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.

Installation and Connections
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
Acquisition Problems.
If there is inadequate disk free space available on the hard disk, you
must use the Remove Application or Delete File function of the Disk
Services menu to free up enough disk space to install the support
software. The approximate space required to install the software is
listed on the label of the floppy disk.
CONFIGURING THE DAS 9200
When there are two or three 92A96 Modules in adjacent slots, they are
automatically formed into a variable-width module by the system
software at power up. If you need to use one 92A96 Module from a
variable-width module, you must reconfigure the DAS 9200 prior to
selecting software support in the 92A96 Configuration menu. Refer to
the discussion of the System Configuration menu in the DAS 9200
System User Manual for details on how to reconfigure variable-width
modules.
Refer to your module user manual for additional information about
connecting probe cables, and positioning and installing 92A96
Modules.
In a system with many 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 2-1 shows where to apply slot number labels.

Figure 2-1. Applying slot number labels.
CONFIGURING THE PROBE ADAPTER
There are two jumpers on the probe adapter. One is set to match the
Read/Write signal convention of your DSP3210 system. The second is
used to configure the probe adapter to acquire data when the BLMN
signal is asserted or to acquire data when the PBD signal is asserted.
Read/Write Signal Convention Jumper
When J4010 is in the 1-2 position, the RW signal behaves like an R/W*
signal in a Motorola 680x0 microprocessor. When J4010 is in the 2-3
position, the RW signal behaves like a W/R* signal in an Intel i386
microprocessor.
Table 2-1 shows the jumper positions for J4010. Figure 2-2 shows the
location of the jumper on the probe adapter.

Installation and Connections
BLMN or PBD Signal Selection Jumper
When J4000 is in the 1-2 position, the BLMN signal is selected. When
the signal is asserted, the signal indicates that the DSP3210 is starting a
quad-word block move operation. When J4000 is in the 2-3 position,
the PBD signal is selected. When asserted, it indicates that the current
external memory access is not on the same page as the previous external
memory access.
Table 2-2 shows the jumper positions for J4000. Figure 2-2 shows the
location of the jumper on the probe adapter.

are both 0 ohm (zero) and actually function as wires straps.
Figure 2-2 shows the location of the resistor on the probe adapter.
Only one of the two resistors is connected to the board. Appendix C
describes how to select one of the two resistor positions.
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 digital signal processor to
accommodate the probe adapter. Refer to Appendix C: Service
Information for the required clearances.
To connect the probe adapter to the SUT, do the following:
1. Turn off power to your SUT. It is not necessary to turn off the
DAS 9200.
CAUTION
Static discharge can damage the digital signal processor,
probe adapter, podlets, or the 92A96 Module. To prevent
static damage, handle all the above only in a static-free
environment.
Always wear a grounding wrist strap, or a similar device,
while handling the digital signal processor 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 in Figure 2-3. This prevents the
circuit board from flexing.
4. Connect the clock and 8-channel probes to the probe adapter as
shown in Figure 2-3. Match the channel groups and numbers on
the interface housing to the corresponding pins on the probe
adapter.

Installation and Connections
8-CHANNEL PROBE
Hold the 8-Channel Probes by
the podlet holder when connecting them to the probe
adapter. Do not hold them by
the cables or necks of the
podlets.
Figure 2-3. Connecting the podlets to a typical PQFP probe adapter.
CAUTION
This JEDEC PQFP (Plastic Quad Flat Pack) probe
adapter is equipped with a clip that has been designed for
tight tolerances.
The clip supports only Plastic Quad Flat Pack devices that
conform to the JEDEC M0-069 October 1990
specification. Attaching the clip to a device that does not
conform to this JEDEC standard can easily damage the
clip’s connection pins and/or the digital signal processor,
causing the probe adapter to malfunction.
Please contact your IC manufacturer to verify that the
digital signal processor you are targeting conforms to the
JEDEC specification.
For best performance and long probe life, exercise extreme
care when connecting the probe to the digital signal
processor.

Installation and Connections
5. Line up the pin 1 indicator on the digital signal processor with
the pin 1 indicator on the target head of the circuit board.
CAUTION
Failure to correctly place the probe adapter onto the
digital signal processor may permanently damage all
electrical components when power is applied.
Center the clip on the digital signal processor and apply
an equal downward force on all four sides of the clip,
slightly rocking the adapter in a clockwise circle.
Do not leverage the probe adapter when installing or
removing the probe.
6. Place the probe adapter onto the SUT as shown in Figure 2-4.

Installation and Connections
CAUTION
The probe adapter board may slip off or slip to one side of
the digital signal processor because of the extra weight of
the podlets. This can damage the digital signal processor
and the SUT. To prevent this from occurring, stabilize the
probe adapter by placing a nonconductive object (such as
foam) between the adapter and the SUT.
