Connections

Serial connection - Main

This connector uses a serial connection and requires the following input during element creation:

SERIAL CONNECTION:

  • Direct connection:

    • Bus address: between 0 and 255
    • Baudrate: Should match the settings on the pCO5 and application.
    • Databits: Should match the settings on the pCO5 and application.
    • Stopbits: Should match the settings on the pCO5 and application.
    • Parity: Should match the settings on the pCO5 and application.
    • FlowControl: Should match the settings on the pCO5 and application.

  • Interface connection:

    • IP address/host: The polling IP of the device.
    • IP port: The IP port of the device.
    • Bus address: The bus address of the device. Range: 0-255.

Configuration

The Carel PCO5 Lennox needs to be set to the bus parameter selected in DataMiner.

In case of a direct serial connection, the pCO5+ application settings for baud rate, stop bits, and parity need to match the ones specified in DataMiner.
