1.4.4. Forward & Reverse Limit Switch Inputs
Attach the Forward/Reverse Limit Switch as shown. Do not connect the GND elsewhere. The Talon
SRX provides a pull-up to 2.5v, so typically an external pull-up is not needed. Only use Talon SRX
3.3V or 5.0V power if an external pull-up is used. The default setting of “Normally Open” ensures an
“out of the box” Talon SRX functions even if no limit switch is connected. See the Software
Reference Manual to change the default Limit Switch behavior from “Normally Open”.
