4.3 TTL UART Connection
To connect via the TTL UART interface to a host PC, we suggest using a USB serial converter from TTL-UART
(5V) to USB interface.
Communication with the host PC, for example when using TRINAMIC’s TMCL-IDE, is done via the Virtual
COM port installed by the converter driver.
More information on the TMCL-IDE and the latest release can be found here:
www.trinamic.com
The converter cable must be connected to pins 1, 8, and 9 (GND, RXD, TXD) of the I/O connector.
Note
Default Baud Rates
The default baud rate is 9600 bps.
In bootloader mode, the baud rate is 115200 bps.
Info
USB to UART converter
For example, the TTL-232R-5V from FTDI is working with the module and has
been tested. More information on this converter is available on the FTDI website:

NOTICE
5V TTL UART Level
The TTL UART interface works with 5V level. Take special care when selecting a
converter cable for USB connection.
