I just got a Deluxe Serial Adapter and am trying to figure out how to connect it to the serial port on the recent-model roomba. (product suggestion: db9 to mini-din with the necessary electronics and correct wiring might be a good seller)
One thing I’m not clear on is the vcc pin, does this mean that the serial adapter needs it’s own power supply? I was assuming it would be powered by the serial cable to the PC.
other than tx->rx and rx->tx what connextions do I have to make?
The spec for the roomba can be found here: irobot.com//images/consumer/ … Manual.pdf
Thanks for any suggestions.
