3.2.2.1 RS-485 Single Connection
When a single device is connected using RS-485, and a terminating resistor is required, move
the jumper on J22 to pins 1 and 2 to enable the terminating resistor. The device
communicating with the charger needs its own terminating resistor installed.
* Typical RS-485 applications tie the shield to earth ground at only one (1) location along the
network. Consult your organization's standard network grounding practices.
