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 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.
The NS-205A switch provides +12~48VDC redundant power inputs to help ensure continuous operation by using a second power source.
The NS-205A also has a DIP switch for enabling or disabling broadcast storm protection, providing another level of flexibility for different industrial applications.
