FT2232H DUAL HIGH SPEED USB TO MULTIPURPOSE UART/FIFO IC
Version 2.21
Clearance No.: FTDI#77
RS485 is a multi-drop network – i.e. many devices can communicate with each other over a single two
wire cable connection. The RS485 cable requires to be terminated at each end of the cable. Links are
provided to allow the cable to be terminated if the device is physically positioned at either end of the
cable.
In this example the data transmitted by the FT2232H is also received by the device that is transmitting.
This is a common feature of RS485 and requires the application software to remove the transmitted data
from the received data stream. With the FT2232H it is possible to do this entirely in hardware – simply
modify the schematic so that RXD of the FT2232H is the logical OR of the level converter device receiver
output with TXDEN using an HC32 or similar logic gate
