I have purchased a Minim OSD and Pixhawk from 3DR. I have no problem connecting my Pixhawk to Mission Planner but the Minim OSD will not connect to the OSD config tool. Does the Minim connect via the Pixhawk USB connector when connected to the Pixhawk telemetry port?
I read on other forums about an “FTDI cable” - is this required to connect the Minim OSD to a laptop? If so, why on earth is the Minim OSD not sold with it, or customers at least advised to purchase it with the Minim?
Will other cables work?
@Jono2014,
Did you follow these setup instructions: http://copter.ardupilot.com/wiki/common-minim-osd-on-screen-display-for-fpv-index/
The 3DR Minim OSD product webpage http://store.3drobotics.com/products/apm-minimosd-rev-1-1 clearly states that a FTDI cable is required for setup/programming.

Thanks for the quick response TCIII!
I did follow the setup procedure as specified but clearly missed the requirement for the FTDI cable when ordering from 3DR - my mistake . It will take a while to get the original cable from 3DR, can I use another USB to serial converter like this in the meanwhile?: communica.co.za/Catalog/Details/P0007172259

@Jono2014,
I have successfully used other USB to TTL serial adapters also so if the pin outs and connections are correct it should work.
