This product is a Safety Class I instrument that is provided with a protective
earth terminal when installed in the mainframe. Check the mainframe,
Digital I/O Module, and all related documentation for safety markings and
instructions before operation or service.
Refer to the WARNINGS page (page iii) in this manual for a summary of
safety information. Safety information for preventive maintenance, testing,
and service follows and is also found throughout this manual.
protection when pe rfor m in g eq uipm e nt main te na nc e or repai r.
WARNING
SERVICE-TRAINED PERSONNEL ONLY. The information in this
manual is for service-trained personnel who are familiar with
electronic circuitry and are aware of the hazards involved. To
avoid personal injury or damage to the instrument, do not
perform procedures in this manual or do any servicing unless
you are qualified to do so.
CHECK MAINFRAME POWER SETTINGS. Before applying
power, verify that the mainframe setting matches the line
voltage and that the correct fuse is installed. An uninterruptible
safety earth ground must be provided from the main power
source to the supplied power cord set.
GROUNDING REQUIREMENTS. Interruption of the protective
(grounding) conductor (inside or outside the mainframe) or
disconnecting the protective earth terminal will cause a
potential shock hazard that could result in personal injury.
(Grounding one conductor of a two-conductor outlet is not
sufficient protection.)
IMPAIRED PROTECTION. Whenever it is likely that instrument
protection has been impaired, the mainframe must be made
inoperative and be secured against any unintended operation.
REMOVE POWER IF POSSIBLE. Some procedures in this
manual may be performed with power supplied to the
mainframe while protective covers are removed. Energy
available at many points may, if contacted, result in personal
injury. (If maintenance can be performed without power applied,
the power should be removed.)
10 General Information Chapter 1
WARNING
USING AUTOTRANSFORMERS. If the mainframe is to be
energized via an autotransformer (for voltage reduction) make
sure the common terminal is connected to neutral (that is, the
grounded side of the main’s supply).
CAPACITOR VOLTAGES. Capacitors inside the mainframe may
remain charged even when the mainframe has been
disconnected from its source of supply.
USE PROPER FUSES. For continued protection against fire
hazard, replace the line fuses only with fuses of the same
current rating and type (such as normal blow, time delay, etc.).
Do not use repaired fuses or short-circuited fuseholders.
Cautions This section contains CAUTIONS which must be followed to avoid damage
to the equipment when performing instrument maintenance or repair.
CAUTION
MAXIMUM VOLTAGE/CURRENT. The maximum voltage that may
be applied between any connector pin and any other point, shield, or
chassis is 5 VPeak.
STATIC ELECTRICITY. Static electricity is a major cause of
component failure. To prevent damage to the electrical components in
the Digital I/O module, observe anti-static techniques whenever
working on a Digital I/O module.
Chapter 1 General Information 11
Digital I/O
Description
The HP E1330A/B Digital I/O Module is an "instrument" in a VXIbus
mainframe. As such, each Digital I/O module is assigned an error queue,
input and output buffers, and a status register.
NOTE
HP E1330A/B
Description
Instruments are based on the logical addresses of the plug-in modules. See
the HP 75000 Series B Installation and Getting Started Guide to set the
addresses to create an instrument.
The HP E1330A/B provides four independent 8-bit digital I/O ports
compatible with TTL logic levels. Each port can be software config ured for
operation as input or output with either positive or negative true logic. The
ports can be combined to provide 16 bit (WORD) or 32 bit (LWORD)
operations. In addition to the eight digital data lines, six handshake lines are
included per port. The handshake lines can also be combined (via jumpers
on the component assembly) to provide proper handshaking for combined
ports. The data lines of each port are provided with a jumpered pull-up for
dry contact closure sensing. User connections to the Digital I/O module are
made through two 60-pin connectors on the rear panel.
The HP E1330B added SCPI command capabilities related to LWORD and
Block operations. The procedures in this manual work equally well with
either an HP E1330A or HP E1330B.

Digital I/O Module
Serial Numbers
Digital I/O modules covered by this manual are identified by a serial
number prefix listed on the title page. Hewlett-Packard uses a two-part
serial number in the form XXXXAYYYYY, where XXXX is the serial
prefix, A is the country of origin (A=USA), and YYYYY is the serial
suffix. The serial number prefix identifies a series of identical instruments.
The serial number suffix is assigned sequentially to each instrument.
The serial number plate is located on the backplane connector. If the serial
number prefix of your instrument is greater than the one listed on the title
page, a Manual Update (as required) will explain how to adapt this manual
to your instrument.

Procedure 1. Verify that the module is properly installed in mainframe
The Functional Verific atio n Tes t fo r th e HP E133 0A/ B mo du le s co ns is ts of
sending the *IDN? command and checking the response. This test can be
used to verify that the module is connected properly and is responding to a
basic command.
2. Verify that the mainframe has passed its power-on test.
3. Send *IDN? to the module (see example following)
4. The return should be as follows (revision number may vary):

The procedures in this section are used to provide a high level of confidence
that the module is meeting published specifications. The Operation
Verification test is a subset of the Performance Verification tests and is
suitable for checkout after performing repairs.
The Operation Verification Test is performed by completing the Digital
Test (Test 2-1) as described in the Performance Verification test procedures.
This test is usually sufficient to verify that the module is meeting its
specifications.

Description
Do not perform any of the service procedures shown unless
you are a qualified, service-trained technician and have read
the WARNINGS and CAUTIONS in Chapter 1.
Equipment required for module troubleshooting and repair is listed in Table
1-1, Recommended Test Equipment. Any equipment that satisfies the
requirements given in the table may be substituted. To avoid damage to the
screw head slots, use a T8 Torx driver to remove the front panel handles.
E1330A/B replaceable parts. Service notes, manual updates, and service
literature for the modules may be available through Hewlett-Packard. For
information, contact your ne ar es t Hew l ett- Pac ka rd Sale s and Service Office .
The HP E1330A/B provides four independent 8-bit digital I/O ports
compatible with TTL logic levels. Each port can be software config ured for
operation as either input or output with either positive or negative true logic.
The ports can be combined to provide 16 bit (WORD) or 32 bit (LWORD)
operations.
In addition to the eight digital data lines, six handshake lines are included
per port. The handshake lines can also be combined (via jumpers on the
component assembly) to provide proper handshaking for combined ports.
The data lines of each port are provided with a jumpered pull-up resistors
for dry contact closure sensing. User connections to the Digital I/O module
are made through two 60-pin connectors on the rear panel.
Chapter 4 Service 33
Repair Strategy Hewlett-Packard recommends replacement of the entire assembly in the
event of a failure. Procedures in this chapter describe troubleshooting
techniques.
Troubleshooting
Techniques
Identifying the
Problem
To troubleshoot an HP E1330A/B module problem you must first identify
the problem and then isolate the cause of the problem to a replaceable
assembly. See Chapter 3 — Replaceable Parts for descriptions and
locations of HP E1330A/B replaceable parts.
Table 4-1 lists some common problems for the HP E1330A/B modules,
along with symptoms and possible solutions. If the problem cannot be
identified using these steps, replace the assembly.

Repair and
Maintenance
This section p ro vi de s guidelines for rep a iri ng and mainta in in g th e H P
E1330A/B Quad 8-Bit Digital I/O Module including:
Guidelines
• ESD precautions
• Soldering printed circuit boards
• Post-repair safety checks
ESD Precautions Electrostatic discharge (ESD) may damage static sensitive devices in the
module. This damage can range from slight parameter degradation to
catastrophic failure. When handling the module observe the following
guidelines:
• Always use a static-free work st ation with a pad of conductive rubber o r
similar material when handling module components.
• If a device requires soldering, be sure the assembly is placed on a pad of
conductive material. Also , be sure that you, the pad, and the soldering
iron tip are grounded to the assembly.
Soldering Printed
Circuit Boards
Post-Repair Safety
Checks
The etched circuit board of this module has plated-through holes that
provide a solder path to both sides of the insulating material. Soldering can
be done from either side of the board with equally good results. When
soldering to any circuit board, keep in mind the following guidelines:
• Avoid unnecessary component unsoldering and soldering. Excessive
replacement can result in damage to the circuit board, adjacent
components, or both.
• Do not use a high power soldering iron on etched circuit boards, as
excessive heat may lift a conductor or damage the board.
• Use a suction device or wooden toothpick to remove solder from
component mounting holes. When using a suction device, be sure that
the equipment is properly grounded.
After makin g re pa ir s to the module, inspect the module for any signs of
abnormal internally generated heat, such as discolored printed circuit boards
or components, damaged insulation, or evidence of arcing. Determine and
correct the cause of the condition. Then perform Test 2-1 as described in
Chapter 2 — Verification Tests to verify that the module is functional.
