WARNINGS
The following general safety precautions must be observed during all phases of operation, service, and repair of this product. Failure t o comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and
intended use of the product. Hewlett-Packard Company assumes no liability for the customer’s failure to comply with these require­ments.
Ground the equipment: For Safety Class 1 equipment (equipment having a protective earth terminal), an uninterruptible safety earth ground
must be provided from the mains power source to the product input wiring terminals or supplied power cable.
DO NOT operate the product in an explosive atmosphere or in the presence of flammable gases or fumes.
For continued protection against fire, replace the line fuse(s) only with fuse(s) of the same voltage and current rating and type. DO NOT use repaired fuses or short-circuited fuse holders.
Keep away from live circuits: Operating personnel must not remove equipment covers or shields. Procedures involving the removal of covers or shields are for use by service-trained personnel only. Under certain conditions, dangerous voltages may exist even with the equipment switched off. To avoid dangerous electrical shock, DO NOT perform procedures involving cover or shield removal unless you are qualified to do so.
DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built into this product have been impaired, either through physical damage, excessive moisture, or any other reason, REMOVE POWER and do not use the product until safe operation can be verified by service-trained personnel. If necessary, return the product to a Hewlett-Packard Sales and Service Office for service and repair to ensure that safety features are maintained.
DO NOT service or adjust alone: Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resusci­tation, is pr esent.
DO NOT substitute parts or modify equipment: Because of the danger of introducing additional hazards, do not install substitute parts or per­form any unauthorized modification to the product. Return the product to a Hewlett-Packard Sales and Service Office for service and repair to en­sure that safety features are maintained.

Safety Considerations

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.
