I am currently trying to build a robot and therefore bought the TReX Jr Motor Controller. To communicate with the controller I got a FTDI TTL To USB Serial Converter Cable which is shown under Com3 in the Windows (8.1) device manager.
When I try to connect to the Controller via TRex Configurator 100608 with the following settings
Then I get the following Error
Could not detect a TReX motor controller on port COM3
The cable I use has the following signals
and I connected the CTS# , TRS# to TTL SI respectively TTL SO. In addition to that I connected the ground pin to G.
I also removed the mode select jumper to enable serial communication.
Did I miss anything ? Is there any way to get more information about the error ?
Any help would be appreciated.
Thanks
Oliver
