RS485 (for BACnet MS/TP):
For terminating the RS485 line with a 120Ω resistor it is necessary to put ON dip 1, like in figure
The maximum length of the cable should be 1200m (4000 feet)
Here some codes of cables:
Belden: p/n 8132 - 2x 28AWG stranded twisted pairs conductor + foil shield + braid shield;
Belden p/n 82842 - 2x 24AWG stranded twisted pairs conductor + foil shield + braid shield;
Tasker: p/n C521 - 1x 24AWG twisted pair conductor + foil shield + braid shield;
Tasker: p/n C522 - 2x 24AWG twisted pairs conductor + foil shield + braid shield

ETHER ET:
The Ethernet port is used for programming the device and for MQTT and BACnet/IP communication
The Ethernet connection must be made using Connector2 of HD67938-B2 with at least a Category 5E cable The maximum length of the
cable should not exceed 100m The cable has to conform to the T568 norms relative to connections in cat 5 up to 100 Mbps To connect the
device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC is recommended the use of a cross cable

EW CO FIGURATIO / OPE CO FIGURATIO :
The “ ew Configuration” button creates the folder which contains the entire device’s configuration
A device’s configuration can also be imported or exported:
To clone the configurations of a Programmable “BACnet Slave / MQTT - Converter” in
order to configure another device in the same manner, it is necessary to maintain the
folder and all its contents;
To clone a project in order to obtain a different version of the project, it is sufficient to
duplicate the project folder with another name and open the new folder with the
button “Open Configuration”
