Attaching External XNNet Controllers
An XNNet device is any device that sends and receives XNNet protocol over the Link A (XNNet) port.
AMX AutoPatch XNNet control devices include remote control panels, e.g., the CP-15 and CP-20A.
AMX AutoPatch XNNet accessory devices include SBCs and Preset SBCs.
The instructions below are for attaching a device to the Link A (XNNet) port, found on the CPU board (3
RU enclosures) or on the XNNet Expansion board (2 RU enclosures). For more information, see the
individual device's documentation.

3. Loosen the screws on the Link A connector.
4.
Insert the two wires of the XNNet link cable from the device into the Link A connector leaving the
