Connecting to an STM23 using USB
The USB-COMi-M (8500-003) from Applied Motion is an excellent choice for USB to serial conversion. It can be used
for all RS-232, RS-422 and RS-485 applications. The USB-COM-CBL from byterunner.com can be used for USB to RS-232
connection only. These adapters use the FTDI chip set and are compatible with Windows XP and later, including 64 bit
versions.
Note: Prolific-based USB serial adapters do not work with Vista 64 or Windows 7 64 bit operating systems.
For RS-232 conversion using the USB-COMi-M (8500-003), use the DB9 connector and set the switches according to the
diagram below. The DB-9 connector is not used for RS-485.
