 8- bit dial code switch integrates a 120Ω ended-terminal resistance between CANH
and CANL, no need to connect externally. The first 6 bits are dialed OFF, the
relative value is 0, when they are dialed ON, the relative value is 1. When the code
8 is dialed ON, the resistor is conducted.
 Address combination value = dial code 4 × 8 + dial code 3 × 4 + dial code 2 × 2 +
dial code 1 × 1. Speed combination value = dial code 6 × 2 + dial code 5 × 1.
 The dial code switch must be configured before the power is on, it's not valid to
dial after the power is on, it will take effect when power-on again.
Start number configuration
 Dial code 1-4 are used to configure address combination value through dial switch,
then the controller set relative IO and AIO start number of expansion module
according to this address combination value.
