15.3. Connection to KNX
NOTE
The way to connect the KNX bus to the gateway is the same for all applications.
• Port A / KNX
Connect the KNX bus to connectors A3 (+) and A4 (-) of the gateway's Port A.
IMPORTANT
Respect polarity.
15.4. Connection to BACnet
• Ethernet connection for BACnet IP
Connect the BACnet IP network to the Ethernet port of the gateway. The correct cable to use depends on
where the gateway is connected:
– Connecting directly to a BACnet IP device: use a crossover Ethernet UTP/FTP CAT5 or higher cable.
– Connecting to a hub or switch of the LAN of the building: use a straight Ethernet UTP/FTP CAT5 or higher
cable.
IMPORTANT
If there is no response from the BACnet devices to the frames sent by the gateway:
– Check that they are operative and reachable from the network connection used by the gateway.
– Check the gateway Ethernet interface sending Pings to its IP address using a PC connected to
the same Ethernet network.
– Contact the network admin to be sure there are no limitations regarding UDP communication or
ports blocked.
IMPORTANT
If communicating through the LAN of the building, contact the network administrator and make
sure traffic on the used port is allowed through all LAN paths.
NOTE
After powering up the Intesis gateway for the first time, DHCP will be enabled for 30 seconds.
After that time, if a DHCP server provides no IP, the default IP 192.168.100.246 will be set.
