USB to RS-485 Converter
Build a RS-485 Network in minutes with this USB to RS-485 converter based on the FT232RL USB to Serial converter. This device includes USB Mini interface and USB cable. Four on-board screw terminals provide connection to a 3-wire RS-485 network. A fourth terminal provides a regulated 5VDC output for use in future expansion applications. While this device supports many baud rate options, we suggest using a baud rate that is compatible with our RS-485 nodes. Our suggested default baud rate of 9600 allows for greatest distance. NCD RS-485 nodes also support 19.2K, 38.4K, and 115.2K baud.
This device includes on-board USB, TX, and RX LEDs and Texas Instruments SN65HVD12D RS-485 driver chip.

RS-485 Serial Compatibility Notes
The NCD RS-485 Serial communications module is compatible with NCD ProXR, ProXR Lite, Fusion, and Taralist series controllers. This module was designed to work with NCD devices, but may be used with devices outside the NCD family. This device acts as a transparent RS-485 to USART serial converter. Non-NCD products will require a software networking protocol to support multiple devices.
