Wiring Note:
 ECI0016PA control card uses dual-power, and ZIO expansion module uses dual-
power. When using, main power supply of expansion module and main power supply
of controller can share one power. When they use different power supplies, controller
power EGND needs to connect to expansion module power GND, otherwise CAN may
be burnt out.

When connecting multiple ZIO expansion modules on the CAN bus, a 120-ohm
resistor needs to be connected in parallel between the CANL and CANH terminals, for
the ZIO expansion module that is with 8-digit dialing codes, the terminal resistor can
be realized by dialing the code (DIP).
