Communication with slave products
If it has been planned to install one or more products cascaded from the main unit or to set this up for a future connection,
refer to the below images to enable communication between the main unit and the cascaded units.
Opposite to Master Same as Master Opposite to Master
We advise you to use different coloured cables to avoid inverting the connections.
Attention: As indicated in the connection diagram, the master unit, to be configured as such, must not have other devices
connected in the C1 and C2 terminal blocks.
Attention: It is necessary to adhere to the connection between the S1-C1 and S2-C2 signals to avoid causing damage to the
electronic device.
Configuration of master product: slave
Check that the master unit doesn't have other devices connected in the terminal blocks (C1 and C2), then turn it on. After
the first 10 seconds during which the red LED will remain steady, the product will emit two alternating white and red light
pulses and will be configured automatically as MASTER.Only once the product has been identified as main MASTER unit it
is possible to start configuring the SLAVE1.
Do not send any command from remote to the slave units.
Make sure the MASTER unit starts working before turning on the next (SLAVE) unit by means of switch "0/1" in order to give
the MASTER unit time to configure the SLAVE units in the desired sequence.
Turn on the SLAVE unit in sequence with switch 0/1, as explained below.
Each unit must only be turned on after the previous unit has effectively started working:
1. Master Unit
2. Slave 1 with operation opposite to Master
3. Slave 2 with operation same as Master
4. Slave 3 with operation opposite to Master
