HP E1458A

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.
