4.5 CAN interface
The CAN-bus is connected via terminal plug 1. A maximum of 32 CAN users
can be connected in one bus segment.
The CAN-bus needs a terminating resistance of 120
Ω
in the first and last bus
users
.
A terminating impedance is integrated into the MP60 module which is
activated by the S14 DIP switches (see page 14).
