This is what you can risk, if you buy the cheap chineese converters of doubtful origin.

How can you be sure that we are not using junk components in our converters?
Well, if we did, then our customers would have unusable converters by now, and since it's our core products, it would completely destroy our business for good.

So, pay a bit more, awoid the cheap copycrap, and be sure you have a quality product that don't give you any unwanted surprises.

Need an X-ray scanner?
Well, then we'll recommend the Balteau NDT AIS229, not because we know a lot about x-ray systems, but because we can assure that they use the best components, such as our communication converters, when they build their systems.

Product change notification - September 2015
The are 2 modifications for the USB485-CPT.

Now it have in-build 120 Ohm termination resistor, while before there was none.
Now the cable is 3 wire 0.25 unscreened, while before it was 3 wire 0.10 screened.

The change is because the previous cable was too vulnerable for mechanical stress, so it's much stronger now, and several customers have asked for termination resistor, so we decided to include that in the new version.

USB485-STISO and USB485-STIXL are converters for 2 wire half duplex systems.
STISO was our first product, but several customers requested larger terminals, so we made the STIXL, and since its introduction, it have become our best selling converter.

The only difference between those 2, are the size of the terminals for the RS485 cable.

There are no reasons to make 2 allmost identical converters, so we've decided to have a minimum stock of the STISO, and ONLY for exsisting customers.

So, we recommend the STIXL for new customers.

Just got a new supply of USB-A connectors from Molex Inc.
Yes, they are more expensive than other connectors, but since we are making quality converters, we decided using quality connectors.
