The base (also referred to as a socket) is used for supplying power to the module, for synchronization, and for data transfer. The operating mode configuration is done using DIP switches.
Setting the address
The address is set in binary form using the first seven switches. The address 0 corresponds to no fixed hardware configuration. In such case, the address can be set using the Slave Setup Assistance tool.
The terminating resistances must be activated on the last base of each UART by setting DIP switches 9 and 10 to the up position; otherwise, reflections may occur on the line, leading to disturbances.

The 8th switch is for activating the hot swap feature. Enabling this stores the module configuration in the socket, which is useful when swapping comprised modules with the same module type.
Module
These DIP switches are for setting the UART the module will be assigned to, as well as de/activating the termination resistors
Q.series Classic Hardware
ON the 10-pin DIP switch block, the UARTs can be set and bus termination activated:
- UART1: Pins 1 and 2 UP (Pins 3-8 DOWN)
- UART2: Pins 3 and 4 UP (Pins 1-2, 5-8 DOWN)
- UART3: Pins 5 and 6 UP (Pins 1-4, 7-8 DOWN)
- UART4: Pins 7 and 8 UP (Pins 1-6 DOWN)
Bus Termination ON: Pins 9 and 10 UP
Bus Termination OFF: Pins 9 and 10 DOWN
If the address is not set using the DIP switches, the address must be set using test.commander.
