The RS485-WiFi „INTRE” interface is a device used to convert signals between the RS485 bus and the Wi-
Fi 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 unit is mounted in a hermetic enclosure protecting against adverse
environmental conditions.

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 IDEE 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.
