NOTES:
DIP switch position 6 on ON position enables a 121Ω termination resistor to RS-485 two-
wire configuration only (must be kept on OFF position in any other configuration).
DIP switch position 8 on ON position enables a 121Ω termination resistor to CAN port.
Configurable serial link 1
Depending on the DIP switch positions, the configurable serial link pin functionalities differ
(refer to Table 3).

NOTE: If a two-wire or four-wire differential port configuration is selected, in function of your network
configuration, you should put bias resistors on transmitter or receiver lines to maintain the
proper idle voltage and force the line to the idle condition.
