A cost effective Ethernet extension from Amplicon

Ethernet extension doesn’t need to be expensive or difficult, the ED3101 is an easy to use, cost effective Ethernet extender that features plug-and-play installation using existing copper twisted-pair infrastructure to connect Ethernet devices and networks at high speeds over long distances. The unit can operate over long distances supporting up to 50Mb/s at a distance of 300m and 1Mb/s at a distance of 1,900m.

The ED3101 must be used in pairs or alternatively an ED3101 can be used in conjunction with an ED3141 - a hardened version for harsh environments. This solution is ideal for systems that require an office grade device at the central location and a hardened extender for field installation for example in roadside cabinets or remote works.

Whether you need to connect to a remote office, private-network or remote automation the ED3101 is the perfect solution. Using layer 2 of the OSI model (data link layer), the ED3101 transparently passes all higher-layer protocols including VLAN tagging, multicast addressing and industrial fieldbus protocols such as Modbus/TCP and Profinet IO.

The ED3101 is supplied with a power supply, single Ethernet port and a configuration DIP switch. The DIP switch is used to configure where the extender is located; Local (CO) or Remote (CPE). This makes the ED3101 one of the easiest extenders to use on the marketplace today.

USB to serial conversion
In the industrial sector laptop computers are used as a tool for accessing devices but these are no longer supplied with an RS-232 interface. As there are still a large number of serial devices being used in the industrial sector this can cause problems when trying to connect to legacy devices.

The Moxa UPort 1250 and 1250I converters, now available in the UK from Amplicon, allow PCs to connect easily to an industrial bus over a USB port. There are three different interfaces for industrial serial communication, RS-232, RS-422 and RS-485. Most converters are only able to support one or two of these interfaces, forcing field engineers to keep several different converters in their toolkit.

With its compact size and flexible 3-in-1 RS-232/422/485 interface, the UPort 1250 provides engineers with a single solution that easily handles a variety of legacy serial devices.
