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 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 / Modbus TCP / Mitsubishi C. Controller
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.

Gateway’s connections
PortA
Not used
PortB / Modbus RTU
Connect the EIA485 bus 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.
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 66).
