CONNECTIONS
ELECTRICAL & MECHANICAL FEATURES
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 (UDP) / Console (UDP & 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).
Default IP is 192.168.100.246.
PortA / R1/R2 Samsung NASA
Connect the R1/R2 bus of Samsung NASA Outdoor Units to the connectors A3 (R1) A4 (R2)
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.
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. Bus biasing
and termination resistor for EIA485 can be enabled for PortB by means of a dedicated DIP switch
– see table
below.
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.
