4.2 Connect to KNX

Connect + and – terminals of the KNX bus to the IntesisBox KNX connector (Figure 4.1).
The polarity is important. Once connected correctly the KNX Tx led (Figure 4.1) will start
blinking. If that doesn't happen check that the cable is connected properly.
How to check if there is communication with the KNX bus is explained in the LinkBoxMB
Manual (section 5).

4.3 Connect to Modbus

4.3.1 Connect to Modbus RTU

Connect the communication cable coming from the Modbus RTU network to the port marked
as Modbus RTU of IntesisBox (Figure 4.1). Two methods to connect to the Modbus network
can be used:
 The RS485 port if the network is RS485 2-wire. Connect the + and the – to the
respective port in the master device (polarity matters)
 The RS232 port if the connection is point to point to one single master.

Manual (section 5).

4.3.2 Connect to Modbus TCP

Connect the communication cable coming from the network hub or switch to the ETH port
(Figure 4.1) of IntesisBox. The cable to be used depends on where the IntesisBox is being
connected:
 Connecting directly to a Modbus TCP master device:
CAT5 cable
 Connecting to a hub or switch of the LAN of the building: a straight Ethernet UTP/FTP
CAT5 cable
In case there is no communication with the IntesisBox, check that the Modbus TCP devices
they are operative and reachable from the network connection used by IntesisBox. Check
the IntesisBox Ethernet interface sending Pings to its IP address using a PC connected to
the same Ethernet network.
