The USB - RS485 2 Wire IoT Module enables the mangOH™ development board to connect to devices and networks that use the half duplex RS485 serial bus protocol to communicate. Based around a highly integrated FTDI chipset, standard and non-standard baud rates from 183 baud up to 3Mbaud are available. Separate TX and RX LEDs provide a visual indication of transmit and receive data as an aide to debugging data communications.

For ease of use, the driver direction switching is managed in hardware, and the USB device simply maps to a standard /dev/ttyUSBx device in the operating system. A 120R network termination resistor can be enabled or disabled by inserting or removing an on-board Jumper - thus allowing the module to be placed either at the end or in the middle of a RS485 network.
