Features
Provides 1 x 100-FX fi ber port for NS-205AF/NSM-205AF series
Provides 2 x 100-FX fi ber ports for NS-206AF/NSM-206AF series
Full duplex IEEE 802.3x and half duplex backpressure fl ow control
Automatic MDI/MDI-X crossover for plug-and-play
Store-and-forward architecture
Redundant dual +12 VDC ~ +48 VDC power inputs
Broadcast Storm protection
The NS-206AF/NSM-206AF is a 4-port unmanaged Ethernet with 2 fi ber ports switch. Using fi ber optics, you can prevent noise from interfering with your system
and supports high-speed (100 Mbps) and high-distance (up to 60 km) transmissions.
The NS-205AF/NSM-205AF/NS-206AF/NSM-206AF provides a wide +12 VDC ~ +48 VDC power range to fi t all the common power standards found in industrial
automation, without external power converters. The wide power input lowers installation and maintenance costs.

Both power inputs can be connected simultaneously to live DC power sources.
If one power source fails, the other live source will act as a backup, and automatically supplies all of NSM-205AF/NSM-206AF series power
needs.

Specifi cations
External power supply is connected using the removable terminal block:
PWR: Power input and should be connected to the power supply (+)
GND: Ground and should be connected to the power supply (-)
F.G. : F.G. stands for Frame Ground (protective ground). It is optional. If you use this pin, it can reduce EMI radiation; improve
EMI performance and ESD protection.
