Ethernet Switching Hub
Switch104 PC/104 10/100 Ethernet switching hub for embedded computers offers low power dissipation (1.5W), an extended temperature rating (-40C to +85C), and a high MTBF (1.51 million hours). The switching hub 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 unit is 3.550x3.775 in. (90x96 mm) in size and offers network connections through either onboard RJ-45 jacks or via right-angle 4-pin Molex connectors.Supporting auto-MDI-MDIX network installation, the Switch104 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. 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 board 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, auto-speed sensing, and bridge loop prevention.
