If the external WiFi module is connected to the serial port of the emergency display, the remote control may lose communication with the control unit.
This condition is indicated by the message:
- “searching for network” on the remote control
This behavior is due to interference on the serial communication line.
Resolution
To restore the proper functioning of the system, proceed as follows:
- disconnect the external WiFi module from the serial port of the emergency display;
- connect the external WiFi module directly to the control unit, as indicated in the product's technical manual.
After the correct connection:
- communication between the remote control and the control unit is restored;
- the remote control becomes operational without error messages.
