Connections
Find below information regarding the Intesis connections available.
Power Supply
Must use NEC Class 2 or Limited Power Source (LPS) and
SELV
rated power supply.
If using DC power supply:
Respect polarity applied of terminals (+) and (-). Be sure the
voltage applied is within the range admitted (check table
below). The power supply can be connected to earth but only
through the negative terminal, never through the positive
terminal.
If using AC power supply:
Make sure the voltage applied is of the value admitted (24 Vac).
Do not connect any of the terminals of the AC power supply to
earth, and make sure the same power supply is not supplying
any other device.
Ethernet / BACnet IP
Connect the cable coming from the IP network to the connector
ETH of the gateway. Use an Ethernet CAT5 cable. If
communicating through the LAN of the building, contact the
network administrator and make sure traffic on the port used is
allowed through all the LAN path (check the gateway user
manual for more information). Default IP is 192.168.100.246.
DHCP is enabled by default.
PortA / KNX
Connect the KNX TP1 bus to connectors A3 (+) and A4 (-
) of gateway’s PortA. Respect the polarity.
PortB / BACnet MSTP
Connect the EIA485 bus to connectors B1 (B+), B2 (A-
) and B3 (SNGD) of gateway’s PortB. Respect the polarity.
Note for PortB; 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 port includes a DIP-Switch for configuration of biasing circuit as well as termination:
SW1:
ON:
120 Ω termination active
OFF:
120 Ω termination inactive (default)
SW2-3:
ON: Polarization active (default)
OFF: Polarization inactive
If the gateway is installed in one bus end make sure that termination is active.
Console Port
Connect a mini-type B USB cable from your computer to the gateway to allow communication between the
Configuration Software and the gateway. Remember that Ethernet connection is also allowed. Check the user manual
for more information.
USB
Connect a USB storage device (not a HDD) if required. Check the user manual for more information.
Ensure proper space for all connectors when mounted (see section 7).
