USB TO RS485 SERIAL CONVERTER CABLE Datasheet

Version 1.4

Clearance No.: FTDI #75

The USB-RS485-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 comes default as

transparent because of LED implemented inside the plug but can be sold in black colour as well. For

simplicity, the LLLL and CU have been dropped from the following descriptions.

The cable outputs 5V power on the wire by default. This can be modified to output 0V power. The letter X

in the part number indicates the output power selection.
