Do I have to purchase software to program the SureServo?
You can program the SureServo two ways: 1) through the free downloadable software, or 2) through the integrated keypad. All parameters are available in the software and on the keypad. We highly recommend the software for its easy, graphical interface and the ability to use the tuning window, if necessary, to help tune the servo. While the software can be downloaded for free, you can purchase a CD version for $9. The communication cable costs $19.
