To synchronize two gates so they operate at the same time, follow these steps:

1. Connect the Bus Terminals

Begin by connecting the bus terminals of the master and slave control units.

• Important: Ensure that both control units are powered off, and disconnect any backup batteries before proceeding.

• Make the RS485 bus connections between the master and slave units as shown in the diagram below.
  

You can find the wiring diagram of how to connect two gates to operate simultaneously:

2. Enable RS485 Serial Communication

Once the wiring is complete, configure RS485 communication on both units:

• Master unit: Set A0 to position 11

• Slave unit: Set A0 to position 10
  

⚠️ Important Note:

If the gate installation is switched from the right to the left side, the position of the spring(s) must also be adjusted accordingly.

3. Perform the Learning Process

After setting up the master and slave units, initiate the learning process.
All settings and adjustments must be made through the master unit only.
