This unit
The Keysight/Agilent/HP E2074 is an EISA and GPIO interface card that enables connection of external devices lacking standard interface protocols such as HP-IB or RS-232. The card supports 16-bit data exchange and operates as an EISA/ISA expansion slot card for HP Series 700 workstations and PCs. Two operational modes provide flexibility: Compatibility Mode emulates the HP 98622 GPIO interface, while Enhanced Mode delivers a bi-directional data port with auxiliary control lines for expanded I/O capability.
Technical Specifications
Data Exchange: 16-bit capability
Interface Type: GPIO/EISA Bus
I/O Base Address: Configurable via DIP switch (factory default: hexadecimal 228); Switches 1, 2, and 3 determine address selection; Switch 4 unused
Data-In Clocking: Three selectable settings
Physical Weight: 3 lbs per unit
Key Features
Dual Operating Modes: Compatibility Mode for legacy HP 98622 emulation; Enhanced Mode with auxiliary control lines
Connection Flexibility: Configurable handshake methods, multiple data-latching options, and selectable data width and polarity
Auxiliary Status and Control Lines: Extended control capability beyond base GPIO functionality
Address Configuration: DIP switch-selectable I/O base address with conflict avoidance for multi-interface installations
Typical Applications Data acquisition and control systems requiring connection to external devices without inherent protocol support. The card accommodates applications needing flexible handshaking, variable data widths, and custom control signaling.
Compatibility & Integration
Operating Systems: HP-UX versions 9.x and 10.x on Series 700 workstations; Microsoft Windows 95 or Windows NT on PCs
Hardware Requirements: EISA/ISA expansion slot
Installation: Standard card installation into expansion slot with DIP switch configuration of I/O base address prior to deployment
Keysight / Agilent / HP E2074 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keysight / Agilent / HP E2074. Calibration covers per-channel threshold accuracy, input leakage current, logic level high/low margins, and signal timing verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Keysight / Agilent / HP E2074 faults: ESD-damaged input protection, failed driver ICs, connector pin damage. Most failures involve ESD-damaged input protection circuitry, failed logic driver ICs, or mechanical connector pin damage. Board-level component replacement is standard practice.
