4.2 Introductory information.
Parameters of the RS485-WiFi interface can be configurable in order to adjust them to the intended
operation mode. The configuration is via web browser after correct logging, i.e. typing correctly username and
password.
The ‘Digi Device Discovery’ program is also helpful as it allows previewing important parameters of the
interface at the preliminary stage of the configuration. The application seeks out modules available at the range of
a router and informs about the assigned IP address and MAC unique address.
Download the ‘Digi Device Discovery’ program from the following page:

To perform the configuration of the RS485-WiFi interface, a minimal connection arrangement is to be set,
as shown below:

that enables performing the configuration.
A newly purchased Wi-Fi interface is delivered with basic configuration (factory settings) which is not
adjusted to correct operation in the system.
As the communication with the interface is via radio waves, it is important to adjust your router accordingly
so that it can establish connection with the interface. The most convenient solution is to own a separate router or to
restore the factory settings of the one in use (if possible). If there is more than one Wi-Fi networks in the place
where the configuration is being made, one can avoid communication interference by reducing the power the
interface RS485-WiFi emits. To do so, unscrew the antenna of the interface and place it near the router with which
it is going to be connected.
In this manual, the configuration of the Wi-Fi interfaces has been based on a wireless 'LinkSys WRT54GL’
Wi-Fi router.
4.3 STEP 1 – Restoring the factory settings.
Router:
To restore the factory settings of the router, check the device’s manual and perform actions following the
manufacturer’s instructions. In most cases, the actions narrow down to finding the reset button at the back panel of
the enclosure and holding it for approx. 5s. After releasing the button, wait approx. 1 min for the correct initiation of
the router. The initiation restores the factory settings to:
