Powering the device

A power supply working with any of the voltage range allowed is needed (check section 8). 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.

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.

6.2.2 BACnet MSTP

Connect the EIA485 bus to connectors A (B+), B (A-) and SG (SNGD) of gateway’s Port. 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.

Connection to the configuration tool

This action allows the user to have access to configuration and monitoring of the device (more information can be

found in the configuration tool User Manual). One method to connect to the PC can be used:

• Ethernet: Using the Ethernet port of Intesis.
