Worked first Go!
I plugged the device into the raspberry pi's usb port , searched /var/log/messages for the new interfaces and then connected to them using minicom (Terminal emulator) Recommended product works with Raspberian on a Pi nicely as a agret 4 port terminal server!

Functional and Straightforward
Works great. Prolific Driver disk provided helped to ease our setup. USB ports not labeled but can be identified using simple feedback/loopback connector. Would buy again.

Works well
Didn't brick my pi. Works well with Solar Assistant and the EG4 3k inverters. I upgraded to 6k units but I still use the 3k units so I'm still using this cable. I tried using a noname single cable and my pi fried. These are pricey but worth the money
