Product Information

The Technobox, Inc. P/N 8518 provides eight industry standard 16550-based UARTs using RS422 signaling levels. Each port has 121 ohms parallel termination on the receive side. The board’s feature set is configured without using any jumpers, plug-on mezzanines or complex FPGAs. Instead, functions are implemented by selective population of the boards eight configuration sections. At the heart of the design is a single Exar XR17V58 Octal UART and sixteen Intersil ISL3177E Full duplex RS485/RS422 transceivers (no enables).

The front-panel I/O interface is a standard 68-pin SCSI-style connector. Neither PN4 nor P16 rear I/O is supported. Rear I/O capable variants (either air-cooled or conduction-cooled) can be built, however. Various breakout panels and cable accessories are available to convert the 68-pin front-panel I/O to support user requirements. For example, Technobox, Inc. P/N 4988 can be used to convert the output to eight DB9 connectors. The XMC interface connector is VITA 42 style. Technobox, Inc P/N 8518 is similar in function to Technobox, Inc. P/Ns 2316 and 5288, offering an immediate solution for migrating from the PMC-to-XMC form factor.
