## Long description

USB to RS-485 Adapter PREMIUMCORD ku2-232D provides a USB 2.0 connection to a single-port RS-485 serial interface. The adapter converts USB signals to differential RS-485 levels (two-wire) for communication with industrial devices, controllers and instrumentation. It is powered from the USB bus and offers a DB9 male output or a short DB9-to-terminal-block adapter included in the package for direct wiring of Data+, Data-, 5V and GND.
Advantages

It is plug-and-play, requires no external power supply, IRQ or I/O address, and supports hot swap. The package includes the converter, an 80 cm USB extension cable, a terminal block adapter, and a driver CD. The device uses the FTDI FT232RL chipset and is compatible with Windows (98/ME/2000/XP/Vista/7/10), Mac and Linux.

How to use
Install the appropriate FTDI driver for your operating system from the included CD or the manufacturer website. Connect the adapter to a host computer using the supplied USB cable. For RS-485 wiring use the DB9 male pins or attach the short terminal-block adapter: connect Data+ to Data+ and Data- to Data- between the adapter and the remote device, and connect GND between all devices; 5V is available on the terminal if external device power is needed. Multiple RS-485 devices can be daisy-chained on the same two-wire bus as shown in wiring examples.
Usage recommendations
For stable RS-485 communication, keep cable lengths and topology appropriate for baud rate, use proper termination resistors at bus ends when required, and ensure common ground connections between all devices. Prefer shielded twisted-pair cable for Data+ and Data- to reduce interference.
