PRV-1059 PC104 10/100 Fast Ethernet Switch

5-Port PC/104 10/100 Fast Ethernet Switch, Unmanaged

The Parvus 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 Curtiss-Wright 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. 

The PRV-1059 is also available integrated in a rugged enclosure featuring a MIL-STD-704 power supply and MIL-DTL-38999 connectors pre-qualified to MIL-STD-810 thermal, shock, and vibration conditions. See the DuraNET 1059 for additional information.
