The CIM-300 has terminals for the BACnet MS/TP connection. DIP switches are used to set transmission speed and line termination and to select the custom Device Object Instance Number. Two hexadecimal rotary switches are used to set the BACnet address. Two LEDs are used to indicate the actual status of the CIM-300 communication. One LED is used for indication of correct connection to the pump, and the other is used to indicate BACnet communication status.
