12 General Information
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.
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 configured 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.
See Appendix A of the HP E1330A/B User's Manual for HP E1330A/B
specifications. These specifications are the performance standards or limits
against which the instrument may be tested.
