4.11.1. CANopen Communication
Notes regarding EtherCAT and CAN communication options:
• Note that CAN and EtherCAT are available in different hardware versions and not
operational simultaneously.
• Please see Section 4.2 above for P/N definitions.
In order to benefit from CANopen communication, the user must have an understanding of the
basic programming and timing issues of a CANopen network.
Notes for connecting the CANopen communication cable:
• Connect the shield to the ground of the host (PC). Usually, this connection is soldered
internally inside the connector at the PC end. You can use the drain wire to facilitate
connection.
• Ensure that the shield of the cable is connected to the shield of the connector used for
communications. The drain wire can be used to facilitate the connection.
• Make sure to have a 120-Ohm resistor termination at each of the two ends of the network
cable. The Gold Solo Trombone’s CAN port is non-isolated.
