We have now purchased multiple RS485 connectors from Hjemslund. It is always a pleasure ordering from them as the items arrive timely and exactly as specified. We look forward to many years of doing business together!

Bought an RS485 adapter for reading modbus power meters. Product worked on the first try, also on Windows 10. Best price by far I could find, great service and fast shipping. Would buy again.

I needed a win 10 compatible USB to RS485 adapter for a solar inverter, but the inverter manufacturer's adapter is only win 7 and below compatible. I passed Adrian as much information as I could, about my system, and he confirmed that the half duplex adapter should do the job. I ordered, and the device arrived promptly, in good packaging, and with a really cleverly designed driver/documentation disk in the box lid. The device itself looks good, it's robust, and the terminal block is well made too. Software installation was extremely straightforward, and after re-reading the inverter manual, I got the RS485 wiring sorted and I was up and running!Well done Hjelmslund Electronics and Adrian, and thanks!

I'm using a two-line USB-RS485 converter to read out data from a Vaisala weather station and a USB-RS485 full duplex converter to communicate between a computer and an industrial laser. Both units work perfectly and have a very nice suite of configuration options. The purchase and delivery worked very smoothly. Recommend highly.

Very professional handling of orders. If ordered, a few hours later is the confirmation with date of delivery, tracking link and invoice. Is always delivered correctly. I have now RS485-USB interface and USB-galvanic isolation. Very user friendly, professional and for the interface with up-to-date driver. Highly recommended!

I run into some problems with other converster which they claim to be isolated. I have ordered 2 USB485-STIXL and they work as expected. The service could not be better. The items are reasonably priced, great help and fast delivery.

I ordered a usb485-MB45 with RS 485 in order to replace controller cable that smc wanted to sell for 4 times the price i paid to hjelmslund. After some compatibility issues (due to smc specificities) solved with the help of hjelmslund (had to rewire the rj45 connector), i ordered 2 more and he offered me to ship them already rewired. Great help
