NS-208 CR
Unmanaged 8-Port Industrial 10/100 Base-TX Ethernet Switch
- Automatic MDI / MDI-X crossover for plug-and-play
- Each port supports both 10/100 Mbps speed auto negotiation
- Store-and-forward architecture
- Full duplex IEEE 802.3x and half duplex backpressure flow control
- 2.0 Gbps high performance memory bandwidth.
- Supports +10 ~ +30V DC voltage
- Reverse Polarity Protection
- Supports operating temperatures from –30 ~ +75 °C
- DIN rail mount for industrial usage
The NS-208 has 8 Ethernet Switching ports that support 10/100Base-T, with a 10/100M auto-negotiation feature and auto MDI/MDIX function. It can connect 8 workstations and automatically switches the transmission speed (10 Mbps or 100 Mbps) for corresponding connections.
The flow control mechanism is also negotiated. There is link/data rate LEDs for each port to aid trouble-shooting. Port connectors are shielded RJ-45.
