G.3: Single-Axis Serial Connection
For RS-232 serial bus control of a single axis, set the CAN node address of that axis to
zero (0). Note that if the CAN node address is switched to zero after power-up, the
amplifier must be reset or power cycled to make the new address setting take effect.

G.4: Multi-Drop Serial Connection
A serially connected amplifier can be used as a multi-drop gateway for access to other
amplifiers linked in a series of CAN bus connections. Set the CAN node address of the
serially connected amplifier (gateway) to zero (0). Assign each additional amplifier in the
chain a unique CAN node address value between 1 and 127. For more information on
CAN node address assignment, see Network Configuration (p. 81). Use 120 Ohms
termination on the first and last amplifier.
