The Agilent/Keysight 31391A is an RS232 extension cable designed for test and measurement system interconnect applications. This 15 ft cable bridges parallel IEEE 1284 and DB25 serial interfaces, enabling equipment integration where native connector compatibility is unavailable. The cable ships in original retail packaging.
Technical Specifications
• Cable Length: 15 ft
• Connector A: Parallel (IEEE 1284) Male
• Connector B: DB25
• Manufacturer: Agilent/Keysight
• Model: 31391A
– Key Features
• Established IEEE 1284 parallel interface on one end
• Standard DB25 serial connector on opposing end
• Extended reach at 15 ft for distributed test configurations
• Original manufacturer packaging
– Typical Applications
• Legacy instrument interconnect in automated test equipment (ATE) environments
• Serial data communication between parallel-equipped devices and DB25 serial ports
• Test system integration where cable extensions bridge non-native connector pairs
– Compatibility & Integration
The 31391A accepts IEEE 1284 male connectors and terminates with DB25 serial interfaces. Integration into existing test benches requires compatibility with both parallel and DB25 endpoints. The 15 ft length accommodates moderate equipment spacing within laboratory or production floor deployments.
