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 type of modbus connection can be used simultaneously, Modbus TCP, Modbus RTU EIA485, or
Modbus RTU EIA232, the type of Modbus connection to use must be selected within the configuration software LinkBoxMB.
Modbus TCP connection: This connection with the Modbus TCP master device can be done directly using a ethernet
CAT5 crossover cable, or through the LAN of the building, in this case use a ethernet CAT5 straigh cable to connect to a
switch or hub of the LAN, check with the network administrator that the TCP traffic and the port used (502 by default) are
allowed through all the LAN path used.
Modbus RTU EIA485 connection: 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
devices connected to the bus, and in each end of the bus it must be a termination resistor of 120 ohms. IntesisBox has an
internal bus biasing circuit that incorporates the termination resistor, if you install IntesisBox in one of the ends of the bus
then do not install an additional termination resistor in that end.
Modbus RTU EIA232 connection: Connect the serial cable EIA232 coming from the Modbus RTU master to the connector
Modbus RTU EIA232 of IntesisBox, this is a DB9 male (DTE) connector in which only the lines TX, RX and GND are
used, see details of the pinout in the user's manual. Respect the maximum distance of 15 meters in this serial line
EIA232.
3. Connection with the FC330A panel: Connect the serial cable EIA232 coming from the panel to the connector FC330A EIA232 of
IntesisBox, this is a DB9 male (DTE) connector in which only the lines TX, RX and GND are used. See details of this connection in
the user's manual. Respect the maximum distance of 15 meters in this serial line EIA232.
4. Use the software LinkBoxMB to configure IntesisBox. See the user's manual for details.
