Resistance Setting
The 2nd dial code of the function dialer is used for setting the matching
resistance of the gateway of 485 bus.
When the controller is at the beginning/end of the 485 bus, the controller needs
to be set to be with matching resistance, then the second bit of function dialer is set
to 1; when the controller is not at the beginning/end of the 485 bus, set the controller
to be without matching resistance, and set the dial code to 0.
