DS2100 User's Manual SECTION 6: CANOPEN INTERFACE
PAGE 6-4 C27750-001
CAN Cable Wiring
The CAN-In and CAN-Out ports at J3A and J3B of the DS2100 provide the means to daisy-chain the CAN cabling
between DS2100 units and system conroller. The CAN interface is equipped with driver and receiver for 24 V
systems. These are optically isolated from the internal drive electronics for noise immunity. Internal supply of the
isolated side of the CAN is provided. No user supplied voltage is required. Two daisy chained 9-way D-Sub
connectors, one male, one female are also provided for ease of wiring.
Please refer to CAN Draft Standard 303, ‘Cabling and Connector Pin Assignment’ for further details of the CAN
cabling requirements.
