      Configuring UART and Module Address Settings

      The module's operating mode is configured using DIP switches that need to be set before powering up the system.

      Setting the UART interface

      The RS-485 slave interface (UARTs 1 through 4) and the terminating resistor are configured using the DIP switch located inside the Q.series XL module, directly on the CPU board. UARTs are assigned using position pairs 1+2, 3+4, 5+6, and 7+8 (red, orange, green, and blue). Positions 9+10 (purple) activate the terminating resistor used to terminate the UART.

      The last module of each UART interface must be terminated with a resistor. If a UART is not terminated, reflections may occur on the bus, leading to disturbances or even loss of data transmission.

      Setting the module's address 

      Module addresses can be defined using the DIP switches on the socket. DIP switch positions 1 through 7 are used to assign module addresses in binary form. Address 0 indicates no fixed hardware configuration. In this case, the address can be set using the Setup Assistant.

      When configuring module addresses, start with address "1" on each UART and assign sequential numbers without leaving gaps.

      The 8th switch activates the hot swap feature. When enabled, this stores the module configuration in the socket, allowing for the replacement of faulty modules with others of the same type.

      Setting the module's address with Slave Setup Assistant

      1. Download the latest version of Setup Assistant from our website. No license is required to use this software.

      2. Open Setup Assistant, then select Slave Setup Assistant. The Slave Setup Assistant window will appear. Click the Perform Scan button to search for available controllers on the network.

      3. A separate window will appear, showing all connected controllers. Select the controller of interest and click OK.

      4. The Setup Assistant will scan all UART ports to detect any connected DAQ modules. All detected modules will be listed.

      5. To modify the address of a module, click on the cell under the Address column and enter the new address. Repeat this process for each module as needed.

      6. Click the Write changes button to apply the updated settings.
