Powering the device

A power supply, working with any of the voltage range allowed, is needed (check section 6). 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 KNX

Connect the communication cable coming from the KNX network hub, or switch, to the ETH port (Figure above) of
IntesisBox.
In case there is no response from the KNX installation, or KNX devices, to the frames sent by IntesisBox, check that
they are operative and reachable from the network connection used by IntesisBox.
Check as well if there is a line coupler that it is not filtering the telegrams from/to the IntesisBox.

Connection to Modbus

4.3.1 Modbus TCP

Connect the communication cable coming from the KNX TP-1 network to the KNX port of IntesisBox. The cable to
be used shall be a straight Ethernet UTP/FTP CAT5 cable.

4.3.2 Modbus RTU

Connect the communication cable coming from the Modbus network to the port marked as Modbus of IntesisBox.
Connect the EIA485 bus to connectors B2 (+), B1 (-) and A1 or A2 (SNGD), or to connectors B1 (-), B2 (+) 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.
Connect the serial cable EIA232 coming from the external serial device to the EIA232 connector of gateway's PortB.
This is a DB9 male (DTE) connector in which only the lines TX, RX and GND are used. Details of the pinout can be
seen in the user's manual. Respect the maximum distance of 15 meters.

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). Two methods to connect to the PC can be used:
•
Ethernet: Using the Ethernet port of IntesisBox.
•
USB: Using the console port of IntesisBox, connect a USB cable from the console port to the PC.
