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

Pin Function For Terminal Block:

External power supply is connected using the removable terminal block:

+Vs : Power input (+10 ~ +30V) 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.

Checking Power:

Since the NS-205G consumes 4.8W max, ensure that your power supply is able to meet
this demand. The Input voltage range is +10~ +30VDC.

Power Savings by Number of Connected Ports and Link Status:

Computers do not require Internet access all the time; neither do switches utilize all ports
at all times. When a computer or network equipment is shutdown, switches often remain
on and continue to consume considerable amount of power. With Power saving
technology, NS-205G can automatically detect link status and reduce power usage of
ports that are idle. Computers or any connecting parties set to standby mode (not power
off), however, will not provide significant power savings.

Power Savings by Cable Length:

The powers saving switches have the ability to analyze the length of any Ethernet cable
connected to them for adjustment of power usage accordingly. Shorter lengths require less
power.
