Embedded Ethernet switch plugs and plays

Parvus Corporation has introduced the PRV-1059, a VLAN-enabled five-port PC/104 Ethernet switch designed and tested to MIL-STD-810F. This rugged network switch features very low power consumption (1.5W) and highly reliable extended-temperature operation up to +85C. 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 now supported.

This feature enables any combination of ports to be connected together in subnets for use in a small secure or nonsecure network.

Fully IEEE802.3 and IEEE802.3u 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 stand-alone 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 lookup engine, along with support for autocrossover, autopolarity, autonegotiation and bridge loop prevention.

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 90 x 96mm in sise.

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.

The PRV-1059 switch has a list price of US $199 for base models and $249 for models with VLAN support.

nonRoHS and RoHS compliant (lead-free) versions are available from stock to 6 weeks.
