7 Functional Description of the Fieldbus Modules
7-29
Connector pin assignment
The pin assignment of the
communication connector (9-pin
Sub-D socket) is identical with the
CAN connection of the link
modules in the Freelance 2000
system.

Electrical isolation
The three CAN channels are electrically isolated from each other and from the
system. To achieve this, the communication signals are isolated through high-speed
optocouplers. The power for the channels is provided by an electrically isolated
DC/DC converter with three isolated output voltages.
