and connect the public ends “EGND”of RS485 communication parties together.
Connect the CANL and CANH of the standard CAN module to the CANL and CANH of
the other side correspondingly. And public ends of the CAN bus communication both
parties are connected together. In CAN bus left and right sides, connect a 120Ωresistor
respectively (please see below graphic).

ZMC303 Motion Controller User Manual V1.5
Connect 422TX and 422RX of RS422 to 422TX and 422RX of the controller
correspondingly, and connect the public ends “EGND”of RS422 communication parties
together.
→Wiring Notes:
⚫As above, RS485 and CAN bus belong to daisy chain topology connection, and RS422
belongs to point-to-point connection (the star topology structure cannot be used).
When the use environment is ideal and there are no many nodes, the branch structure
also can be used.
⚫Please connect a 120Ω terminal resistor in parallel to each end of the CAN bus for
matching the circuit impedance and ensuring communication stability.
⚫Please be sure to connect the public ends of each node on the CAN bus to prevent
the CAN chip from burning out.
⚫Please use STP (Shielded Twisted Pair), especially in bad environments, and make

ZMC303 Motion Controller User Manual V1.5
sure the shielding layer is fully grounded.
⚫When on-site wiring, pay attention to make the distance between strong current and
weak current, it is recommended for the distance to be more than 20cm.
⚫It should be noted that the equipment grounding (chassis) on the entire line must be
good, and the grounding of the chassis should be connected to the standard factory
ground pile.
→Cable Requirements:
Shielded Twisted Pair, and the shielded cable is grounded.
3.2.2. Basic Usage Method
(1) Please follow the above wiring instructions to wiring correctly.
(2) After powered on, please use any one interface among the three interfaces
(ETHERNET, RS232, RS485) to connect to ZDevelop;
(3) Please use the "ADDRESS" and "SETCOM" commands to set and view the protocol
