7.5.2 RS-485 interface
Use the S1 and S2 RS-485 interfaces to retrieve all controller data and to enable
the communication with control centres or other devices.
• S1 interface
– A maximum 10 devices can be used in a master-slave linked circuit
via the this interface.
• S2 interface
– "PIS" pressure and "LIS" level.
– Operating modes of the "PU" pumps.
– Operating states of the motorised ball valve/solenoid valve.
– Values of the "FQIRA +" contact water meter.
– All messages.
– All entries in the fault memory.
The following bus modules form part of the optional accessories available for
interface communication.
 Note!
If required, please contact the Reflex Customer Service for the protocol
of the RS-485 interface, details of the connections and information about
the accessories offered.
7.5.2.1 Connecting the RS-485 interface
Circuit board of the Control Basic controller.
1 DIP switch 1
Proceed as follows:
1. Open the housing cover of the Control Basic controller.
2. Use a screened cable to connect the RS-485 interface to the main circuit
board.
• Terminal 29 (A+)
• Terminal 30(B-)
• Terminal 31(GND)
3. Connect the cable screen at one side.
• Terminal 22
4. Activate the terminators on the main circuit board.
• Dip switch 1

Note!
Activate the terminator when the device is at the beginning or the end
of an RS-485 network.
7.6 Installation and commissioning certificate
 Note!
The installation and commissioning certificate can be found at the end
of the operating manual.
