Unlocking the smart features is simple with the REV SRS Programmer (sold separately).

• Angular Mode
  With the press of a button, the SRS Programmer can set custom angular limits without removing the SRS from the mechanism. These custom limits eliminate the need to fiddle with servo horns or linkages.
• Continuous Rotation Mode
  With the flip of a switch on the SRS Programmer, the SRS can switch from angular mode to continuous rotation mode. The SRS saves time and money by preventing the permanent modification of standard servos.

The SRS has a wide input signal range that some controllers may not be able to produce. Additionally, the output pulse may be abstracted behind several layers of code so that it is unclear what the pulse actually is. If motion over the full 180° isn’t seen, check the pulse width produced by the controller.
