Features and benefits
The PCI dual-port programmable serial interface (PSI) card consists of 2-port serial interface hardware that features a flexible physical connectivity interface (RS-232C/V24, X.21/V11, RS-449, V.35,
or RS-530 standards). Cable types are automatically recognized.
It supports the X.25/LAP-B protocol allowing HP 9000-to-HP 9000 communication, as well as HP 9000 to other systems (HP or non-HP) over packet data networks or leased lines. This is achieved through
the use of HP X.25/9000 Software (P/N J2793B).
Product (P/N J3525A) specific functional specifications
- PCI 2.1 Local Bus Specifications for the system bus.
- Dual-port PCI-based hardware. A green LED per port allows easy checking of the hardware installation and of the cable connection.
- Support speeds ranging from 64 Kbps to 2 Mbps on each PCI port (2 Mbps only supported on X.21, RS-449 and RS-530 interfaces).
- Hardware diagnostics (RESET and external loopback) are integrated into MESA.
