The HP 10269C General Purpose Probe Interface provides a convenient
Introduction method of connecting the HP 1650A, HP 1651A, and HP 16510A logic
analyzers to digital systems through dedicated interface cards. These
dedicated interface cards (preprocessors) allow you to define which
system signals are supplied to the analyzer. Refer to Appendix A for
the specifications of the HP 10269C.

Installation
HP Modei 10269C
The HP 10269C has two 60-pin connectors which allow connection to
dedicated interface cards (ordered separately). A variety of connectors
and cables are available for connecting directly to your system.
The HP 1650A, HP 1651A, and HP 16510A logic analyzer probes plug
directly into connectors on the HP 10269C Interface. This eliminates
the need for individuai probe iead connectors.
For specific connections see the documentation that is shipped with
each of the dedicated interface cards (preprocessors).
A dedicated interface card is installed on the underside of the HP
10269C General Purpose Probe interface and connected to it by two
internal cables (see figure 2). Ribbon cables from the interface card
connect the general purpose probe interface to your target system.
For more specific instructions see the documentation supplied with
each of the dedicated interface cards.
Connect the probe pods from the logic analyzer to the pod sockets on
the general purpose probe interface. These sockets are ¡abeled pod 1
through 5 as shown in figure 1.

General
Description
HP Model 10269C
The HP 10269C General Purpose Probe Interface is a versatile device,
With an interface card instalied, it provides a flexible and convenient
way to probe your target system with the HP 1650A, HP 1651A, and HP
16510A logic analyzers. The software supplied on the flexible disc with
the interface card or preprocessor contains setups for the Format and
Trace Specification menus (where applicable). It also contains an
inverse assembler routine that allows the logic analyzer to display
microprocessor data in the assembly language of the corresponding
microprocessor.
Microprocessor-specific interface modules, with corresponding
software (on flexible discs) are available for many of the most popular
microprocessors. You can use these interface modules to quickly
probe the 8-bit, 16-bit, or 32-bit microprocessor target system or target
system bus of your choice.
These microprocessor-specific interface modules often contain buffers
and gating circuits. The buffers supply address, data, clock, and status
signals from the target system to the pod connectors on the general
purpose probe. For detailed descriptions of these interface modules,
refer to the documentation supplied with each interface card or module.
A user definable interface module is also available. It can be configured
through a wirewrap interface to specific test ports in your system, or
tailored to a specific configuration for a custom microprocessor.

IE | | |
If you have the interface module hooked up and running and observe
Slow Clock slow clock or no activity on any pods of the interface board, check the
+5 V supply coming from the analyzer. To do this:
1, Disconnect one of the logic analyzer cables from the HP 10269C
and measure across pins 1 and 2 (see figure 3).
* If +5 V isn’t observed across these pins, check the internal
preprocessor fuse on the HP 1650A, HP 1651A, or HP 16510A
Logic Analyzer. For information on checking this fuse, refer to
the HP 1650A/51A or HP 16510A service manuals.
* if +5 V is observed across these pins and you feel confident that
the +5 V is getting to the interface module, then the interface
module is most likely the problem. If this is the case, contact
your nearest Hewlett-Packard Sales/Service Office for
information on servicing the board.

The HP 10269C acts as a terminator for the HP 1650A, HP 1651A, and
HP 10269C Pod HP 16510A logic analyzer probes. It also routes the +5 V power from
Connector Pin-Outs the logic analyzer probes to the microprocessor interface modules. All
of this is accomplished through the five 40-pin connectors on the top of
the HP 10269C. Table 1 lists the pin-outs for the odd pins of the five
connectors. Figure 4 shows the pin-out for the pod connectors.

Introduction
HP Model 10269C
Wiring Changes
for the HP 10304B
Certain 8085 Preprocessors (HP 10304B) must be updated to work with
the HP 1650A, HP 1651A, and HP 16510A logic analyzers. These
preprocessors can be easily updated by adding a jumper to re-route a
clock signal, which allows the logic analyzer to probe the 8085 with
only two logic analyzer probes.
The signal being re-routed is the ALE signal from the 8085. ALE is used
as the slave clock for the logic analyzer and is essential for proper
operation of the preprocessor.
The boards requiring modification are HP part numbers:
64655-66501 64655-66502
64655-66503 64655-66504
HP part number 64655-66505 doesn't need to be modified.

To update the preprocessor:
Updating the
Preprocessor 1. Remove the printed circuit board from the preprocessor sheet
metal.
2. Locate pin 1 of the blue 60-pin connector labeled J3. The
connector is shown in figure C-1 from the component side of the
PC board.

been updated.
