10.2 Outdoor Unit Address and Communication Type Setting
Step 1: Power on
Cover the lower panel of the ODU, and power on all IDUs and ODUs.
Step 2: Enter commissioning mode
When the ODU is first powered on, it displays "-. -. -. -.", which means the unit is not commissioned. Long press the “DOWN”
and “UP” buttons simultaneously for 5s on the master ODU to enter commissioning mode.
Step 3: Set the number of IDUs in a system
The digital display of the master ODU displays "01 01", where 1st and 2nd digits always on, 3rd and 4th digits flashing. The
3rd and 4th digits represent the number of IDUs, the initial value is 1, short press the “DOWN” or “UP” button to change the
number. Once the number of IDUs has been set, short press the “OK” button to confirm and automatically proceed to the
next step.
Step 4: Select the system communication protocol
Enter the communication protocol setting interface, the digital display of master ODU displays "02 0", where the 1st and 2nd
digits always on, the 3rd digit off, the 4th digit flashing. The 4th digit of the digital display represents the communication
protocol type, the initial value is 0. Short press the “DOWN” or “UP” button to change the communication protocol.
If the system is all V8 IDUs, and the IDUs and ODUs are connected by PQ communication, please select V8 protocol RS-485
(P Q) communication, and set the 4th digit of the master ODU digital display to 0; ODU factory default V8 protocol RS-485
(P Q) communication.
If the system has a non-V8 IDUs, and the IDUs and ODUs are connected by PQE communication, please select the non-V8
protocol RS-485 (P Q E) communication and set the 4th digit of the master ODU digital display to 1.
If the system is all V8 IDUs, the IDUS and ODUs are connected by M1M2 communication, and all IDUs are powered uniformly,
please select the HyperLink (M1M2) communication + indoor unit uniform power supply, and set the 4th digit of the master
ODU digital display to 2.
If the system is all V8 IDUs, the IDUS and ODUs are connected by M1M2 communication, and there is separate power supply
for IDUS, please select the HyperLink (M1M2) communication + indoor unit separate power supply, and set the 4th digit of
the master ODU digital display to 3.
Once the communication protocol has been set, short press the “OK” button to confirm and automatically proceed to the
next step.
Step 5: IDUs and ODUs address setting
Enter the auto addressing function, the digital display of master ODU flashes "AU Ad" and "X YZ" in rotation. "AU Ad" means
the auto addressing is in progress, "X" represents the address of the ODU, "YZ" represents the number of detected IDUs; the
auto addressing takes about 5-7 minutes, and automatically proceed to the next step after completion.
Step 6: System initialization
Entering system initialization, the digital display of master ODU flashes "AU Ad" and "X YZ" in rotation. "INIt" means
initialization is in progress, "X" represents the address of the ODU, "YZ" represents the number of detected IDUs; the system
initialization takes about 3-5 minutes, and automatically proceed to the next step after completion.
Step 7: End
After system initialization, if there is no fault in the system, all ODUs will enter standby mode and the digital display will
display "X YZ" (“X” represents the address of the ODUs, "YZ" represents the number of detected IDUs), and the unit can be
turned on normally.
After system initialization, if the ODU detects a fault, the digital display of master ODU will display "X YZ" (“X” represents the
address of the ODU, "YZ" represents the number of detected IDUs) and the error code in rotation. Please refer to the Error
Code Table for troubleshooting, and the unit can be turned on normally after the fault is cleared.
Step 8: Other settings
After completing the test run, you can set the relevant functions of the unit according to the actual functional requirements.
For specific operations, please refer to related technical documents. If there is no special requirement, you can skip this step.
