-Modules can be configured using blue-white ([[#hw_configuration_using_dip_switches|HW configuration]]) switches placed next to the power connectors, or alternatively next to the RS485 on some models. Another option is configuration via Modbus registers ([[#sw_configuration_via_modbus_rtu|SW configuration]]). Configuration via DIP switches offers enough options for most applications, while configuration via Modbus registers provides broader possibilities (wider range of addresses and bitrates).

-HW configuration is recommended for the module's first use and the subsequent SW configuration upload.

-===== SW configuration via Modbus RTU =====
-Modules can be easily configured in Mervis, as described in <html><a href="/en:sw:01-mervis:connecting-to-unipi-extension-hidden#reconfiguration_of_the_unipi_extension">this guide</a></html>.

-<WRAP center round box 85%>
-***SW configuration** of the module is used only when all address switches are set to 0 (OFF). Switch states are used only during the module's startup (connecting the power supply, SW reset, Master Watchdog).

-=== Extension xG18: ===
-This module features 6 configurable switches located at the left bottom part. The switch no.6 is placed closest to the power connectors. The lone switch next to the RS485 connector serves to attach/detach terminal resistor, eg. cannot be used for configuration.
