The CAN Connector joins together two CAN devices. For devices that support a CAN bus (such as the Talon SRX), the CAN Connector can be used to "daisy chain" multiple devices together. See Section 1.3.2 of the Talon SRX User's Guide for more details.
Note: Connectors come as a bank of 5. Users will need to gently break apart the board along scored grooves to use them individually.
