Connections
Find below information regarding the IntesisBox 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 / ASCII 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). With factory settings, after
powering up the gateway, DHCP will be enabled for 30 seconds.
After that time, if no IP is provided by a DHCP server, the default
IP 192.168.100.246 will be set.
PortA / KNX
Connect the KNX TP1 bus to connectors A3 (+) and A4 (-
) of gateway’s PortA. Respect the polarity
PortB / ASCII Serial
Connect the EIA485 bus to connectors B1 (B+), B2 (A-
) and B3 (SNGD) of gateway’s PortB. Respect the polarity.
Connect the serial cable E
IA232 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. Respect the maximum distance
of 15 meters.
Note: 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
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.
