The RS485-WiFi „INTRW” interface is a device used to convert signals between the RS485 bus and the WiFi
network. For proper operation, the unit requires an external power supply in the range of 10÷30V DC e.g. drawn from a PSU
of the EN54 series. The physical connection of the interface takes place under galvanic isolation. The unit is mounted in a
hermetic enclosure protecting against adverse environmental conditions.

The Wi-Fi wireless communication.
The Wi-Fi wireless communication can be implemented on the basis of additional interfaces: WI-Fi 'INTW' and
RS485-WiFi, operating within 2,4GHz frequency band, according to the IEEE 802.11 bgn standard.
The WiFi 'INTW' interface shall be mounted in a selected location inside the enclosure so that the antenna is
exposed to the outside.
