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 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 / ASCII TCP/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). Default IP is
192.168.100.246. DHCP is enabled by default.
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 / 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 EIA232 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 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 ASCII serial 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).
