Our production line is over 70 metres long and your product works so well I expects at every stage one of your units monitoring our processes. There's no complex wiring and it’s easy to use. We have one of these units in test at the moment and have been extremely impressed with the ease of use, how easy it is to interface with the unit and with the unit performance. Steve Townend

Thanks for a great product that actually does what it says out the box with easy concise code examples :)

These are making my life easier and saving customers money :)

So far I've used the 8 port un-managed switch, RS-485 to Ethernet and now the US-235 without any issues. Great pricing through Newark, well designed and built products!!
