6. THE S-C02/T CONNECTIONS WITH THIRD PARTY MODBUS

SYSTEMS

6.1. SETTING OF THE S-C02/T SENSORS FOR THIRD PARTY MODBUS

SYSTEMS

15 indexation positions are allowed for Modbus addressing: position 1 to position F included.

Address 0 is not available.

Important: Up to 15 sensors can be connected to the Modbus and each sensor must have a

different address from others in diasy chain.

Note: the sensors are delivered in position 0. They must be manipulated with extreme care.

6.2. THE S-C02/T ELECTRICAL CONNECTIONS WITH THIRD PARTY MODBUS

SYSTEMS

Disconnect the electrical power supply before any operations. The S-C02/T Modbus sensor com-

municates with other components through Modbus connection which is made by a RS485 interface

connected through a double RJ45 connector for daisy chain linking.

All the components are linked to each other via a daisy-chain whose length should not exceed 200 m

with shielded CAT5E cable or better. At the beginning and at the end of the daisy-chain, a termination

is needed. An electrical control board that contains a converter USB -> RS485 and a BUS polarization

is necessary for the Modbus connection schemes. Aereco offers an optimal solution of electrical control

board (ref: ADX1785EX) that is adapted to its S-CO2/T Modbus sensors.
