NS-205G
5-Port Industrial 10/100/1000 Mbps Ethernet Switch
Introduction:
The NS-205G is 5-port unmanaged gigabit switches that support 10/100/1000
Base-T, with a 10/100/1000M auto-negotiation feature and auto MDI/MDIX
function. It can connect 5 workstations and automatically switches the
transmission speed (10 Mbps or 100 Mbps or 1000Mbps) for corresponding
connections.
That is an ideal solution for bandwidth-hungry applications (such as high
resolution digital image transmission, video/audio file streaming/downloading,
and server farm connectivity).
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
Features:
•
Power saving Technology
•
Automatic MDI / MDI-X crossover for plug-and-play
•
Each port supports both 10/100 and 1000 Mbps speed auto negotiation

Store-and-forward architecture
•
Full duplex IEEE 802.3x and half duplex backpressure flow control
•
10 Gbps high performance memory bandwidth.
•
Supports operating temperatures from –40 ~ +75
℃
•
DIN-Rail
