Powering the device

A power supply working with any of the voltage range allowed is needed (check section 9). Once connected the RUN
led (Figure above) will turn on.
WARNING! In order to avoid earth loops that can damage the gateway and/or any other equipment connected to it,
we strongly recommend:
•
The use of DC power supplies, floating or with the negative terminal connected to earth. Never use a
DC power supply with the positive terminal connected to earth.
•
The use of AC power supplies only if they are floating and not powering any other device.

Connection to BACnet

6.2.1 BACnet IP

Connect the communication cable coming from the network hub or switch to the ETH port (Figure above) of Intesis.
The cable to be used shall be a straight Ethernet UTP/FTP CAT5 cable
In case there is no response from the BACnet devices to the frames sent by Intesis, check that they are operative
and reachable from the network connection used by Intesis. Check the Intesis Ethernet interface sending Pings to its
IP address using a PC connected to the same Ethernet network.
Check as well with the network admin that there are no limitations regarding UDP communication or ports blocked.
BACnet IP connection using switch/hub and straight cable

6.2.2 BACnet MSTP

Connect the EIA485 bus to connectors B1 (B+), B2 (A-) and B3 (SNGD) of gateway's PortB. Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω. The gateway has an
internal bus biasing circuit that incorporates the termination resistor. If you install the gateway in one of the ends of
the bus, then do not install an additional termination resistor in that end.
Note: BACnet MSTP only available when port B not used for Modbus RTU integration. Selectable by Intesis MAPS.
