this is a simple RS232 to RS485 converter that is self powered using the TX, RX or RTS, CTS signals for power. The RS232 is DB9 female connector, and the RS422 side is a DB9 male or 4 position terminal block
Baud rate:300-9216000bps automatic detection of serial signal speed.
Interface form:USB type A interface, male head, DB9 male connector connector
Direction control:Using data flow automatic control technology, automatic discrimination and control of
data transmission direction.
The signal indicates that the red light is the power supply, the green light is the
sending signal, and the yellow light is the receiving signal.
-Baud rate automatic detection and zero delay automatic transmission, so you can get high-speed data transmission through the RS-485 or RS-422 interface.
-Effectively protect your expensive and sensitive control equipment against electrical damage,600W static surges, and + 15kV electrostatic protection.
-FTDI Chip supports the widest possible OS compatibility: Windows,Linux and for Mac.
-The shielded cable supports four wires full duplex, two wires half duplex; point to point, point to multi-point communication
4 Kinds of Working Modes: Asynchronous
Point to point / four wires full duplex;
Point to multiple point / four wires full duplex;
Point to point / two wires half duplex;
Point to multiple point / two wires half duplex.

This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.
The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable. The black wire on the FTDI cable is GND, green is CTS. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.
This board has TX and RX LEDs that make it a bit better to use over the FTDI cable. You can actually see serial traffic on the LEDs to verify if the board is working.
This board was designed to decrease the cost of Arduino development and increase ease of use (the auto-reset feature rocks!). Our Arduino Pro boards and LilyPads use this type of connector.
One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.
