4 Connections

Find below information regarding the Intesis connections available.
PortA / BACnet MSTP
Connect the EIA485 bus to connectors A3 (A-), A4 (B+) and A1 or A2 (SNGD) of gateway's PortA. Respect the
polarity.
PortB / Modbus RTU
Connect the EIA485 bus to connectors B1 (B+), B2 (A-) and B3 (SNGD) of gateway's PortB. Respect the polarity.
Note for PortA and 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 in BACnet MSTP port)
OFF: Polarization inactive (default in Modbus RTU port)
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).

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 / Modbus TCP
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.
