Set System Bus Addresses; Switch On Power Supply - Rehau NEA SMART 2.0 Service Manual

7.2

Set system bus addresses

The following components are using the system bus to communicate:
- NEA SMART 2.0 Base units (one Master and up to 4 Slaves)
- NEA SMART 2.0 U-Module (up to 5 modules)
Each of these devices needs an individual address. Double
addresses
block the bus communication.
Note:
The NEA SMART 2.0 Base with address setting "0" is the master of
the system. Only the master is communicating via WLAN or LAN to
router or to a tablet / smartphone / laptop.
Address settings for NEA SMART 2.0 Base (DIP switches are below
the front cover):
Fig. 7-2 DIP switches on Base
Note:
The address setting of the NEA SMART U-Modules starts with the
1st module with address "0" (all dip-switches set to 0, see below).
The address setting of the U-Modules is not in conflict with the
addresses of the NEA SMART 2.0 Base units, even when the DIP
switches have the same position.

Switch on power supply

Note:
Before you switch on the power supply, check again the wiring.
Especially take care, that the wires of the system bus cable (SYSBUS)
are correctly connected.
GND, VDC, 1 and 2 must be connected with the same terminals
on the other units, otherwise the devices will be damaged!
