Agilent E1458A

Description

The Agilent Technologies E1458A 96-Channel Digital
Input/Output module is a C- size, 1-slot, register-based
VXI module that offers twelve 8-bit bi-directional data
ports. It provides block memory transfers and six GPIO
handshake protocols (none, leading edge, trailing edge,
pulse, partial, and strobe) for a wide range of
applications.

Functionally similar to the E1330B, the E1458A is
intended for digital I/O control applications such as
digital subassembly test or data acquisition and control.
Each of the 12 identical ports consists of eight data lines
and six handshake/control lines.

Each 8-bit port is individually configured for positive/
negative true logic and read/write or tri-state condition.
The E1458A is arranged into three banks of four ports
each. Ports can be combined within a bank, allowing data
transmission using bytes, words (16-bit), or long words
(32-bit). Data transmission can be from a single port
(8 bits) or from multiple ports up to all 12 ports.

Refer to the Agilent Technologies Website for instrument
driver availability and downloading instructions, as well
as for recent product updates, if applicable.

Cables

The E1458A ships with four 2-meter cables. For ordering
each additional 2-meter cable, order Agilent part number
E1458-61601. An Opto 22 component cable may be ordered
separately as Option 022.

SCPI

The E1458A SCPI command set is a superset of the E1330B,
allowing existing SCPI application programs to run on the
E1458A. The E1458A SCPI command set supports additional
queries to read back port data and control values, plus new
E1458A capabilities, including monitoring of actual output
port data. The E1458A driver is supported on all C-SCPI/I­SCPI platforms and also as a downloadable driver for the
Agilent E1406A command modules.

Handshake and Control Lines

Three handshake and control lines for each port can be
controlled with SCPI programming. These lines provide the
following functions:
FLAG: Data handshaking line input to the digital I/O
module
CTL: Data handshaking line output by the digital I/O
module
I/O: Input/output status line

Each port has three additional control lines available for
custom handshaking and interrupt functions: PIR
(peripheral interrupt), /RES (peripheral reset), and STS
(status). Control of these three lines is done through
register-based programming.
