DIP Switch Description
The ZMIO310-CAN expansion module generally has an 8-bit DIP switch, dial ON to
take effect, and the meaning of the DIP is as follows:
1-4: these are CAN ID, used to map IO address of CAN expansion module, the
corresponding values are 0-15, different codes relate to different IO starting No.
5-6: CAN communication speed, corresponding values are 0-3, there are four
different speeds.
7: reserved.
8: 120 ohm resistor, dial ON means a 120 ohm resistor is connected between CANL
and CANH.
More details of expansion IO address mapping and communication speed, please
refer to 5.2.2 CAN Bus Expansion Description.
