Gateway’s connections
Power Supply
Must use NEC Class 2 or Limited Power Source (LPS) and SELV
rated 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.
Ethernet / 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.
PortA / DALI #0
Connect the DALI bus to connectors A4 (+), A3 (-
) of gateway’s PortA. Intesis provides 16VDC (+/-2%) DALI voltage
to the bus.
PortB / Modbus RTU (INMBSDAL0640000 / 1 DALI channel)
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.
