EM100 TX Fast Ethernet adapters, designed for PCI, EISA and ISA servers and workstations, are the surest way to connect to 100 Mbits/sec. Fast Ethernet networks. These high speed workhorses combine low-cost with performance for network managers who have already switched to Fast Ethernet.

ONE SPEED ONLY-EXTREMELY FAST

The EM100 TX meets the needs of network managers who have already adopted Fast Ethernet. These savvy users do not want to pay for features they do not need. And they only need the one speed that the EM100 TX delivers-extremely fast.

EASY CONFIGURATION ON ALL PLATFORMS

The EM100 PCI Fast Ethernet adapter is self-configuring; it's base configuration is automatically set in BIOS for maximum convenience. The EM100 ISA adapter is "Plug and Play" compatible, so your system can do all your configuration work for you. The EM100 EISA adapter is compatible with all EISA configuration utilities.

HIGH BANDWIDTH NETWORKING

EM100 TX is ideal for resource-intensive graphics, Windows 95, multimedia, and mission-critical applications which need high throughput to power large amounts of data across the network. And the extremely low CPU utilization of the EM100 makes it perfect for network servers.

For maximum performance, EM100 TX (PCI only) includes 100 Mbits/sec. FDFE Full Duplex capability which doubles the cumulative system throughput rate. Full Duplex capability is easily enabled via software configuration.

Cogent offers Ethernet products to meet every adapter and repeater environment, including 10BASE-2, 10BASE-5, 10BASE-T, 100BASE-TX, 100BASE-T4, and 100BASE-FX (fiber).
