Seitron DA0411 Mode D'emploi page 20

If configured as receiver for PC, the device can be connected to a PC or a home
automation controller instead of a relay module, with which it will communicate
through the RS485 bus. In this way, it is possible to receive all the commands
coming from the radio thermostats to the home automation controller, which
will manage the control outputs of the heat regulation system and a user
interface, if any.
If configured as a receiver with MODBUS® RTU protocol, it will be necessary
to learn the address of the transmitters of which it's wanted to receive the
commands. It's possible to learn up to a maximum of 50 transmitters addresses.
The device will keep updated in memory the status of every learnt address with
the received radio commands from the correspondent transmitter and will act
as "Slave" responding to the requests from the "Master" which periodically
reads the informations of every command.
In case the device is used as an active antenna, the relay modules supply the
power in continuous current to the device through the data cable.
If the device is used as a repeater or receiver connected to a PC, it must receive
the power supply through the two terminals duly shown with 1- and 2+ (Fig. 4).
Working as a repeater
The device is factory configured to operate as an active antenna.
To configure the device as a repeater, remove the JP1 jumper and leave JP2
inserted (as shown with B in Fig. 5). The device works as a repeater and no
longer communicates with the relay modules. In this configuration, 12VDC
power supply must be supplied to terminals 1- and 2+.
Carry out the self-learning procedure of the device's address, on which you
want to repeat the radio command
50 transmitters addresses):
- Turn on the thermostat or other transmitting device and set it up in "test"
mode. (This means that it will continuously transmit an ON command,
followed by an OFF command after 3 seconds).
- Press the "self-learning" key for a second, shown with
the self-learning procedure and the LED
The self-learning key can be pressed, even without removing the cover, using
(it's possible to learn up to a maximum of
