NS-205
5-Port Industrial 10/100 Mbps Ethernet Switch
Introduction
The NS-205 has 5 Ethernet Switching ports that support 10/100Base-T(X), with a 10/100M auto-negotiation feature and auto MDI/MDI-X 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.
LEDs embedded in RJ-45 jacks make for easy monitoring. Port connectors are shielded RJ-45. A power source for +10 ~ +30VDC is required.
Features
- Automatic MDI/MDI-X crossover for plug-and-play
- Each port supports both 10/100 Mbps speed auto-negotiation
- Store-and-forward architecture
- Full-duplex IEEE 802.3x and half-duplex backpressure flow control
- 1.4Gbps high-performance memory bandwidth.
Integrated look-up engine with dedicated 1024 unicast MAC addresses. - Supports +10 ~ +30V DC voltage
- Supports operating temperatures from –40 ~ +75 ℃
- DIN rail mount for industrial usage
- 1.4Gbps high-performance memory bandwidth.

LED functions
Standard RJ45 female connectors are provided. A standard RJ45 plug cable is all that is necessary to connect your device to the unit since the switch supports auto crossover.
Table 1 shows the LED indicator functions. The module includes an internal.

Ethernet Wiring:
When making a connection to another device using a straight-through UTP cable, make sure the MDI-X to MDI connection rule is followed. The following figure illustrates the pin assignments of a straight-through UTP and a crossover UTP cable:
Checking Power:
Since the NS-205 consumes 2.4W, ensure that your power supply is able to meet this demand. The Input voltage range is +10~+30VDC.
The external power supply is connected using the removable terminal block as shown below:
Pin Function For Terminal Block:
The 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.
Dimensions:
The width of the NS-205 is just 33 mm, so it can be used where space is important.
