u Bypass Analog OutputsThere are two analog outputs that can be configured for a signal level of 0 to 10 Vdc or 4 to 20 mA. The signal level is controlledby the position of jumpers J2 and J3 on Control PCB A2 and by the values set to drive parameters H4-07 and H4-08.u Serial CommunicationsRefer to BACnet Communications on page 359 or Refer to MEMOBUS/Modbus Communications on page 379 for detailsdepending on the applicable serial communications protocol.n Serial Communication TerminalsTable 3.9 Control Circuit Terminals: Serial CommunicationsType Name Description NotesMEMOBUS/Modbus orBACnetCommunicationIG5 Isolated groundGround reference for RS-485 signals.
