Model: NS-205
Unmanaged 5-Port Industrial Ethernet Switch
The NS-205 has 5 Ethernet Switching ports that support 10/100 Base-TX, with a 10/100M auto-negotiation feature and auto MDI/MDI-X function. It can connect 5 workstations and automatically switches the transmission speed (10 Mbps or 100 Mbps) for corresponding connections. The flow control mechanism is also negotiated. There is activity/link/data rate LEDs for each port to aid trouble-shooting. Port connectors are shielded RJ-45.It contains "soft start" function with overload protection, high-low voltage protection. The width of the NS-205 is just 33 mm, so it can be used where space is important.
  • Automatic MDI / MDI-X crossover for plug-and-play
  • Each port supports both 10/100 Mbps speed auto negotiation
