Internal Product Review
The ACJ/XSJ-NK is a well-executed Copley Controls CAN adapter kit built around a D-Sub 9F to RJ-45F adapter and a CAN CiA DR-303-1 pinout standard. An included RJ-45 to flying leads cable with crimps and a 121 Ω terminator plug make field wiring straightforward and support stable network termination.

Product Description:
The ACJ/XSJ-NK is an adapter and cabling kit manufactured by Copley Controls as part of the Copley Controls Accessories series. It connects the CAN network on the manufacturer’s servo drives to external wiring in industrial automation cells. By converting the drive’s D-Sub service header to an RJ-45-style outlet and providing a precrimped harness, the kit speeds installation and reduces field termination errors. This arrangement allows CAN signals to reach distributed amplifiers without requiring additional custom hardware.
The kit includes a board-mount adapter that provides a D-Sub 9F-to-RJ-45F connection, allowing the nine-pin service connector to connect through a standard Ethernet-style jack. Pin mapping follows the CAN CiA DR-303-1 convention, making the layout compatible with common CANopen nodes. The adapter plugs directly into the drive at the J1/J4 header, which offers 10 positions for signal and shield conductors. An assembled cable with a length of 10 ft (3 m) mates with this jack and terminates in flying leads that are crimped for push-in cage clamps, eliminating the need for on-site stripping and tinning. The cable jacket and conductor twist provide the characteristic impedance required by balanced CAN transceivers. A molded strain relief protects the RJ-45 plug from excessive bending during panel movement.
The ACJ harness routes CAN and ground through H7, L2, and G3, while the XSJ harness uses H2, L3, and G7. A removable terminator plug with a 121 Ω resistor is included, allowing the bus to be terminated at the final node without separate components. Color coding follows CiA guidance, with CAN-H carried by the white/orange conductor, CAN-L carried by the solid orange conductor, and CAN-GND carried by the white/green conductor. The kit contains an adapter, cable, and terminator for establishing the required CAN connection. Lead insertion pins 7, 8, and 9 accommodate the applicable signal conductors. The separate ACJ and XSJ pinouts allow the kit to connect with the corresponding drive families while maintaining the appropriate CAN and ground paths.
