question

I am using some USB to TTL converters that came with some JDK BMS I purchased some years back, that are called JDK communications uart and are in a small black box with a usb printet socket and a small white 4 pin socket and are isolated usb devices as they contain opto isolators.

The attraction is price, they cost 19 dollars landed while the Victron direct cables are 75 dollars and i have 6x Victron devices

These original units marked JDK uart tools v 1.6 (FT232 Future Technology) work perfexrly when connecting to the Victron ve.direct ports.

I then recently purchased some more and they are marked v 1.7 (CH340 chips - Qinheng) but these do not work.

The boards are exacly the same apart from the uart chip size difference.

I am using a raspberry pi 3 running Venus version 3 large image. The consol command lsusb reports the following
