Programming Jumper
The firmware on the PSCU can be customized by the end user. This makes it easy to tailor the use of
this Servo Controller to your application’s needs. You may also write you own firmware from scratch and
take advantage of additional features of the hardware that may be implemented. If you wish to develop
your own firmware you may simply download the Propeller Tool software from our website at
http://www.parallax.com/propeller. The programming jumper is installed by default, but can be removed
to prevent accidentally overwriting the code. Removing the jumper disconnects the DTR line from the
/RES line on the Propeller, thereby disabling the Propeller chip from being programmed or identified. You
can still communicate serially whether the jumper is installed or not.
