+    %: I got the DB9 pinout from [here](https://armdroid1000.wordpress.com/control-protocol/). AFAIK, that pinout is correct. However, **the "accessory inputs" annotations are all WRONG**. The ones I have marked "accessory outputs" are indeed outputs and are driven by the same driver IC as the stepper motors, so they can do the same 380 mA as the motors at the 12V or whatever that is supplied. **The ones marked "accessory inputs" are NOT inputs. They are lower power logic outputs (0-5V, 20 mA).**
 
 The fourth accessory output is mounted on the shoulder.
