Frequently Asked Questions

What is the maximum distance for an Ethernet cable connected to the Moxa EDS-208?

Ethernet cable length is limited by the standard for the speed. For 10/100 Mbps Fast Ethernet ports on the EDS-208, the maximum cable segment length is 100 meters (328 feet). This is a standard limitation for twisted-pair Ethernet connections.

This limit ensures signal integrity and prevents data corruption over longer distances. Exceeding this distance requires network regeneration, typically achieved through another switch or a media converter.

Always use quality Cat5e or Cat6 industrial Ethernet cables to achieve the full 100-meter distance reliably.

Can the Moxa EDS-208 handle industrial automation protocols like Modbus TCP?

Yes, the Moxa EDS-208 fully supports industrial automation protocols such as Modbus TCP. As a standard Ethernet switch, it operates at the data link layer (Layer 2) and forwards Ethernet frames.

Protocols like Modbus TCP, EtherNet/IP, and PROFINET are built upon TCP/IP and Ethernet, meaning they are compatible with any standard Ethernet switch. The EDS-208 does not interfere with or interpret these protocols.

Its store-and-forward switching mechanism ensures reliable delivery of protocol packets between connected industrial devices.

What are the power supply requirements for the Moxa EDS-208?

The Moxa EDS-208 is designed for flexible industrial power integration, accepting a wide DC input voltage range. It supports inputs from 9.6 VDC to 60 VDC.

This wide voltage range allows it to be powered by various DC sources commonly found in industrial settings, such as 12V, 24V, or 48V batteries or power supplies. The switch also features dual power inputs for redundancy.

Utilizing dual power inputs with separate sources enhances system reliability. If one power supply fails, the other will maintain continuous operation of the switch.

How do I install the Moxa EDS-208 in an industrial control cabinet?

Installation is typically straightforward, utilizing its DIN-rail mounting capability. Secure the switch onto a standard 35mm DIN rail within your control cabinet.

Alternatively, an optional wall-mount bracket can be used for mounting on flat surfaces. Ensure adequate ventilation around the switch to prevent overheating, especially in densely populated cabinets.

Connect your industrial Ethernet cables to the RJ45 ports and wire the DC power input to the terminal block, observing polarity.

What is the difference between an unmanaged and a managed industrial Ethernet switch?

An unmanaged switch, like the EDS-208, offers plug-and-play functionality with no configuration required. It automatically handles network traffic for basic connectivity.

A managed switch provides advanced features such as VLANs, QoS, SNMP monitoring, and port configuration. These require setup and network expertise.

For simple network expansion where advanced control isn't needed, an unmanaged switch like the EDS-208 is more cost-effective and easier to deploy.

Does the Moxa EDS-208 support Power over Ethernet (PoE)?

No, the Moxa EDS-208 is a standard unmanaged industrial Ethernet switch and does not support Power over Ethernet (PoE) output. It requires a separate power supply for its own operation.

PoE switches provide electrical power along with data over the Ethernet cable to compatible devices, such as IP cameras or wireless access points. The EDS-208 only transmits data.

If PoE is required for your connected devices, you would need to use a PoE-enabled switch or inject PoE power using a separate PoE injector.

What are the environmental specifications for the Moxa EDS-208?

The Moxa EDS-208 is built for harsh industrial environments. It operates within a temperature range of -10 to 60 °C (14 to 140 °F).

It also carries certifications like Class I, Division 2 (for hazardous locations) and ATEX Zone 2, indicating suitability for potentially explosive atmospheres. Its rugged casing provides protection against dust and moisture.

The switch is designed to withstand vibration and shock commonly encountered in industrial settings, ensuring reliable network performance.

How do I troubleshoot a network connection issue with the Moxa EDS-208?

Start by checking the status LEDs on the front panel. Ensure the power LED is on and that link/activity LEDs are lit for connected devices.

Verify that the Ethernet cables are securely plugged in at both ends and are not damaged. Test with a known good cable.

Confirm that the connected devices are powered on and configured correctly, and that the EDS-208 is receiving adequate power within its specified voltage range.

What is the warranty period for the Moxa EDS-208?

Moxa typically offers a standard warranty period for their industrial networking products. For specific details on the Moxa EDS-208, it is best to consult the official Moxa website or your authorized distributor.

Warranty terms can vary by region and specific product series. Always refer to the latest documentation or sales information.

This information will confirm the exact duration and coverage of the warranty.

Can the Moxa EDS-208 be used for video surveillance networks?

Yes, the Moxa EDS-208 can be effectively used to build the network infrastructure for industrial video surveillance systems. It provides reliable connectivity for IP cameras.

Its eight Fast Ethernet ports allow for connecting multiple IP cameras and a network video recorder (NVR) or central monitoring station. Its industrial ruggedness is beneficial for cameras deployed outdoors or in demanding environments.

However, since it's not a PoE switch, you'll need to power the cameras separately. Ensure your network bandwidth can support the video streams.
