Chapter 1 Introduction
This section provides a functional description of the PRV-1059.
Functional Description
PRV-1059 is a rugged VLAN-capable 5-port PC/104 Fast Ethernet switch featuring very low power consumption
and highly reliable extended-temperature operation up to +85°C (185°F). Supporting auto-MDI-MDIX network
installation, the board is designed for simple plug-and-play operation, enabling up to five embedded computing
devices to be networked together using 10BaseT or 100BaseTX Local Area Network (LAN) connections.
Field programmable, port-based VLAN functionality is supported on select models. This powerful feature
enables any combination of ports to be connected together in subnets for use in a small secure or non-secure
network. Fully IEEE 802.3 and IEEE 802.3u compliant, its five transceiver ports are flexibly designed so that any
port can serve as an uplink. The module can either be used as a standalone network switch (no processor board
required) or in combination with embedded systems that support a PC/104 (ISA) bus.
The card integrates fully independent media access controllers (MACs), an embedded frame buffer memory,
and a high-speed address look-up engine, along with support for auto-crossover, auto-polarity, auto-negotiation,
and bridge loop prevention.
Qualified to MIL-STD-810 environmental standards, the compact PRV-1059 switch is ideally suited to space-
constrained, high reliability aviation, industrial, military, and transportation applications where extreme
temperature and high shock/vibration exist. The unit is only 3.550” x 3.775” (90x96 mm) in size. All versions
include mounting holes to facilitate simple installation, as well as support for local or remote monitoring of LED
activity for data RX/TX and connectivity.
Ethernet connections are made through either onboard RJ-45 jacks or right-angle, locking Molex connectors.
The 4-pin Molex headers enable embedded systems to optionally mount RJ-45 jacks in a faceplate, endcap or
enclosure using a Parvus cable set (sold separately), which includes five female Molex to RJ-45
adapters. Power connections can be made through either the PC/104 (ISA) bus or externally through a 2-pin
Molex connector.
