USB-RS232-WE-LLLL-CU-PWR
The USB-RS232-WE cable is un-terminated; it has bare and tinned wires.
The LLLL specifies the length of the cable in cm. The CU specifies the colour of the cable and the colour of
the USB connector. The cable can be either Black or transparent. The USB connector can either be black
or transparent. For simplicity, the LLLL and CU have been dropped from the following descriptions.
