Adjustable Pull High/low Resistors for the RS-485 Port
The UPort uses DIP switches to set the pull high/low resistor values for each serial port.
To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in the OFF
position.
To set the pull high/low resistors to 1 KΩ, make sure both of the assigned DIP switches are in the ON
position. This is the default setting.
