Feature:1. Network card provides drivers for Windows series / Netware series / SCO Unix / Linux and other operating systems, and is suitable for multiple operating systems. In addition, for Windows 2000 / Windows XP / Windows Vista have their own drivers, plug and play.2. Just plug it into the corresponding physical cell identifier slot and install the appropriate driver to use it. For Windows 2000 / XP / Vista, there is no need to install the driver, plug and play.3. Supports 10/100 rate self-adaption, full-duplex half-duplex self-adaption, port supports auto-flip and provide a two-way data transmission rate of 200M, which is the choice for building a 100M network.4. Highly integrated, support multiple operating systems such as for WIN95 / 98 / ME / NT4 / 2000 / XP. In line with IEEE802.3 10Base-T IEEE802.3u 100Base-TX. Support PCI2.1 and PCI2.2, plug and play.5. Automatically monitor the network connection, automatically adapt to 10Mbps or 100Mbps. Support full-duplex flow control, built-in first-in first-out buffer, greatly improves network speed.6. Provide relevant diagnostic software, two indicator lights indicate network connection and running status.7. Support remote boot ROM while supports rich network program and provide rich driver.8. 8139D network card uses for Realtek chips, a high-performance 10/100M adaptive 32-bit physical cell identifier fast Ethernet card, and completly in line with physical cell identifier 22.2 bus specification.9. Auto-negotiation function can automatically identify the speed and working mode of connected switches, hubs and other network devices and automatically switch between 10BASE-T and 100BASE-TX, automatically recognize and adjust the transmission mode and transmission speed .10. In addition, such network card also supports functions such as remote startup, and supports startup modes such as for RPL / PXE.Specification:Item Card: Network cardModel: 8139DTechnical Indicators:Network Standard: IEE802.3 10Base-T IEEE802.3u 100Base-TXPort: A 10M/100M RJ45 interfaceTotal 33MHz 32-bit Physical Cell Identifier Bus Protocol: V2.1 V2.2Physical Media Interface: RJ45Physical Media Type: 10Base-T Type 3 or above UTP (<100m)100Base-TX Category 5 UTP (<100m)Transmission Mode: Full / half duplexTransmission Speed: 10/100Mbps adaptiveUse Network Type: 10M Ethernet, 100M fast EthernetRemote Start Chip Socket: NoneStatus Indicator: Yes.Package List:1 x Network CardNote:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
