5.3.4.2 Cable requirements
Use only shielded encoder cables with twisted pairs.
5.3.4.3 Connector housing requirements
Use metal or metalized 9 pole male D-sub housing. All shields must be connected to the connector
housing.

Communication
5.4.1 Connecting the CAN bus (X6)
A CAN network must be terminated with 120
Ω at both ends. If there are no input/output connectors in
each unit, the CAN bus can also be implemented as an open ring.
typical implementation of three IMDs in a hub. Note that CAN low is always connected to CAN low and
CAN high is always connected to CAN high. Termination resistors are only used in IMD 3 by
connecting pin 2 to pin 4, and pin 7 to pin 8 (it is assumed that the pitch motion controller or main
controller is terminated as well).
