Connections
________________________________________________________________________________________
Notes:
1.
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 (9 to 30 Vdc). 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.
2.
Modbus connection. Only one Modbus connection type can be used simultaneously: Modbus TCP, Modbus RTU EIA485, or Modbus RTU
EIA232, this must be configured within LinkBoxMB software.
Modbus TCP: Connect the cable coming from the Modbus TCP master device to the connector ETH of IntesisBox, use a crossover
ethernet CAT5 cable if connecting directly to the Modbus TCP master device, or an straight ethernet CAT5 cable if connecting to a
switch or hub of the LAN of the building. If connecting using the LAN of the building contact the network administrator and make
sure that TCP/IP traffic and the TCP port used (502 by default) are allowed through all the LAN path.
Modbus RTU EIA485: Connect the EIA485 bus to the connector Modbus RTU EIA485 of IntesisBox. Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 device connected,
and a 120 ohms terminator resistor in each end of the bus. IntesisBox comes with an internal bus biasing circuit which incorporates
internal bus terminator resistor, and thus if you connect IntesisBox in one end of the bus then it is not necessary to install additional
120 ohms resistor in that end.
Modbus RTU EIA232: Connect the serial EIA232 cable coming from the Modbus RTU master device to the Modbus RTU EIA232
connector of IntesisBox, this is a male DB9 connector (DTE) in which only lines TX, RX and GND are used, see pinout details in
the user's manual. Respect the maximum distance of 15 meters for this EIA232 line.
Cerebus connection: Connect the serial EIA232 cable coming from the Cerebus network to the Cerebus EIA232 connector of IntesisBox, this is
a male DB9 connector (DTE) in which only lines TX, RX and GND are used, see pinout details in the user's manual. Respect the maximum
distance of 15 meters for this EIA232 line.

Use the software LinkBoxMB to configure IntesisBox. See the user's manual for details.
