The NS-205 has 5 Ethernet Switching ports that support 10/100Base-T, with a 10/100M auto-negotiation feature and auto MDI/MDIX 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 LED for each port to aid trouble-shooting. Port connectors are shielded RJ-45. The product contains a "soft start" function with overload protection, high-low voltage protection. The width of the NS-205 is just 32.30 mm, so it can be used where space is limited.
