Notes:

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.

Sunways EIA485 connection. Connect the EIA485 bus to the connector Sunways 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.

BACnet/IP connection: Connect the cable coming from the BACnet/IP client device to the connector ETH of IntesisBox, use a crossover ethernet CAT5

cable if connecting directly to a BACnet/IP client device, or a straight ethernet CAT5 cable if connecting to a hub or switch of the LAN of the building. If

communicating through the LAN of the building contact the network administrator and make sure that UDP traffic and the port used (47808 by default) are

allowed through all the LAN path.

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