NS-208A
8-port Industrial 10/100 Mbps Ethernet Switch
特色
• Cost-effective.
• Automatic MDI/MDI-X crossover for plug-and-play
• Store-and-forward architecture
• Full duplex IEEE 802.3x and half duplex backpressure flow control
• Each port supports both 10/100 Mbps speed auto negotiation
介绍
The NS-208A has 8 Ethernet ports that support 10/100 Base-TX, with a 10/100M auto negotiation feature and auto MDI/MDI-X function. All Ethernet ports have memory buffers that support the store-and-forward mechanism, which assures that data can be transmitted properly. The NS-208A supports advanced network standards to optimize network performance, reduce maintenance costs, and secure network safety. The flow control mechanism is also negotiated. There is link/data rate LEDs for each port to aid troubleshooting. Port connectors are shielded RJ-45.
