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.
