3. Product Description

3.1. Product Description

The Viper-002-PL series consists of Ethernet extenders and bridges for propagating Ethernet traffic over existing cabling. The series is based on power line communication (G.hn) and is capable of bridging high bandwidth Ethernet traffic over 2-wire cables, even when there are oxidized connectors.
By simply installing a Viper-002-PL product on each side of the coupler, a bridge connecting the Ethernet networks on each side is created. The power line technology allows using existing cables, which leads to significant financial savings when refurbishing trains. The fact that no configuration is needed further contributes to the ease of use.
The Viper-002-PL series has been thoroughly tested by certified labs to ensure its compliance with the standard for electronic equipment used on rolling stock, the EN 50155. For several characteristics, Westermo exceeds the requirements mandated by the standard, e.g. by providing 1.5 kVrms insulation on all ports.
Furthermore, the design is based on Westermo’s long experience within the rolling stock market, which brings benefits such as vibration safe integrated connector threading, IP67 ingress protection with GORE-TEX® membrane to prevent condensation water build-up and ultimately a high MTBF and long service life under the harshest conditions.
The Viper-002-PL series is built in Westermo’s Swedish factory which is renowned for its extremely high standard, as confirmed by a multitude of quality audits by demanding international customers. The factory is organized according to lean manufacturing principles and it is equipped with sophisticated state-of-the-art quality assurance equipment.
Meeting the requirements for rolling stock, makes the Viper-002-PL series also very well suited for deployment in other applications with severe operating conditions and extreme environments .

3.2. Available Models

3.2.1. Additional Model Information

In most cases, only the Viper-002-T1-PL1 model is used. In cases when two different Ethernet interfaces are used but only one transmission cable is present, different Viper-002-PL models can use same transmission cable without mixing Ethernet interfaces. The two models have different configurations which ensure that they will only connect to the same model and avoid crosstalk.

3.6. Dimensions

Dimensions are stated in mm and are regardless of model.

4. Installation

4.1. Wall Mounting

The product can be wall mounted vertically or horizontally. There are four pieces of 7 mm bores for this. Use four M5, M6 or 1/4″ screws with 12 mm washers on a flat and stable surface.

4.2. Protective Earth Connection

For correct function, the earth connection needs to be properly connected to a designated PE rail. Torx: T25 and torque: 3.2 Nm.

4.3. Connection of Cables

Recommended tightening torque for the M12 connectors is 0.6 Nm. When connecting the power cable, ensure that the pins are connected correctly before tightening the power cable to the unit.

⚠ PROTECTIVE FUSE The power supply wiring must be sufficiently fused.
It must be possible to disconnect manually from the power supply. Ensure compliance to national installation regulations.
Replacing the internal fuse must only be performed by Westermo qualified personnel.

ℹ NOTE – UNUSED CONNECTORS
Unused connectors must be covered by a protective cap (delivered with the product), tightened to the specified torque in order to fulfil the specified ingress protection code.

4.4. Cooling

This product relies on convection cooling. Make sure that it is installed so that the ambient temperature is within the specified temperature range. Avoid obstruction of the airflow around the product.

4.5. Replacement of Product

Disconnect all cables and unscrew the product from the wall. MTTR (Mean Time To Repair), i.e. time for replacement of product is < 10 minutes.

4.6. EN 45545-2 Mounting Notes

Two product can be mounted together and as a single interior non-listed group in the sense of EN 45545-2 definitions. For multiple product, the spacing requirements for interior non-listed groups must be met.

4.7. Getting Started

The product is easy to use and install. The units work in a pair over existing cabling infrastructure and automatically connect to each other when the remote device is sensed over the interconnecting lines.
The installation procedure to get the application up and running is simple.

1. Connect the cable (twisted pair or parallell cable) to X2 pin 1 and 3 (polarity independent).
2. Connect Ethernet to the X1 port on the front of the product.
3. Connect power to the devices.
   The following settings are valid for the Ethernet interface:

• Ethernet auto-negotiation enabled
• Auto MDI/MDI-X
• Auto-polarity enabled

The product will automatically detect the possible data rate to the remote device (over the X2 – PLC interface ).
The link performance can easily be measured after the powerline link is established. Different types of methods and tools can be used.
One example of recommended software for throughput testing is Iperf. Please refer to Iperf user documentation for instructions of usage.

ℹ NOTE
If the PLC link is not established or the established data rate is not sufficient for the application, the distance might be too long between the products.

The product is an unmanaged unit. If performance is low or no connection established, check cabling between the product.

4.8. Configuration

All necessary configurations are preconfigured from factory and no other changes in the settings can be done.
