E.1: Single-Axis and Multi-Drop
An amplifier’s RS-232 serial bus can be used by CME 2 for amplifier commissioning. The serial
bus can also be used by an external control application (HMI, PLC, PC, etc.) for setup and direct
serial control of the amplifier. The control application can issue commands in ASCII format.
For experimentation and simple setup and control, a telnet device such as the standard Microsoft
Windows HyperTerminal can also be used to send commands in ASCII format. For more
information, see Copley Controls ASCII RS-232 User Guide.
The serially connected amplifier can also be used as a multi-drop gateway for access to other
amplifiers linked in a series of CAN bus connections.
Instructions for hooking up a single-axis connection and a multi-drop network appear below.
E.1.2: Single-Axis Connections
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.

E.1.3: Multi-Drop Network Connections
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
CAN Addressing (p. 21) and CAN Interface (p. 101). Use 120 Ohms termination on the first and
last amplifier.
