Automatic Address Detection

Automatic address detection is a function to store the IDs (addresses) of the connected slave modules in the EEPROM of the
bridge module.
The parameters of the connected devices are automatically updated after the IDs are stored in the EEPROM of the bridge
module and unset IDs (addresses) and the same IDs (addresses) are detected.
The ID (address) information stored in the EEPROM is held even when the module is powered off. However, information
about unset IDs, the same IDs, and the parameter information of each slave module are not held.
Whenever starting the system or changing the system configuration, set the correct addresses to all the slave modules and
perform the automatic address detection.

Performing the automatic address detection

To perform the automatic address detection, use the SET switch or Automatic address detection command (RYn1).
Using the SET switch
1.
Check that all of the slave modules are operating normally.
2.
Keep pressing the SET switch on the bridge module until the SET LED (green) turns on.
(At this time, Automatic address detection flag (RX(n+1)4) also turns on.)
3.
When the SET LED flashes for a while and turns off, the ID (address) has been stored.
4.
When Automatic address detection flag (RX(n+1)4) turns off, automatic address detection is completed.
Using Automatic address detection command (RYn1)
1.
Check that all of the slave modules are operating normally.
2.
Turn on and off Automatic address detection command (RYn1).
(At this time, Automatic address detection flag (RX(n+1)4) also turns on.)
3.
When the SET LED flashes for a while and turns off, the ID (address) has been stored.
4.
When Automatic address detection flag (RX(n+1)4) turns off, automatic address detection is completed.
