There are all 8 dial codes on IO board above V1.3 hardware version, 1-4 are dialed to
set CAN address, 5 and 6 set CAN speed, 7 means reserved and 8 means 120Ω resistor
DIP. When dialing ON, the resistor is connected. Old version IO boards don't have DIP
7 and DIP 8, which means a 120Ω resistance is needed to connect externally.
The expansion module with an 8-bit DIP switch (the hardware version above V1.3)
integrates a 120Ω resistance between CANL and CANH. It is controlled by DIP 8.
When dialing ON, the resistance is connected. When multiple expansion modules are
connected on the CAN bus, it is only necessary to dial DIP 8 of the last expansion
module to ON. There is no need to connect a 120Ω resistor outside the terminal.
When each bit is dialed to OFF, the relative value is 0, when ON is related to 1. The
combination value = dial code 4 × 8 + dial code 3 × 4 + dial code 2 × 2 + dial code 1.
Controller sets IO port range of relative IO board according to CAN dial code address.
(Relative IO start number can be seen through controller status in ZDevelop software)
