... By dubbing the software on eg. A Unicam-Programmer This converter is very suitable. The transfer of the software on the Unicam module went relatively quickly. Other converters which do not contain USB 2.0 did not work, for example.. Therefore, the best always make sure that it is a USB 2.0 RS232 Koverter. The packaging of this adapter is very good, both the device and the software (CD) are well protected and in a resealable plastic bag. The stick has a plug-in protection. I can not say anything about the durability, but I seem to screw a bit shaky. Use the EH but not because they do not fit in the RS232 cable from the module.
