Protection against spoofing

with the integration module authentication

Communication loss detection

within 36 seconds

Between a hub or range extender and MultiTransmitter. The detection time depends on the Jeweller or Jeweller/Fibra settings.

Instant detection of wired connection loss, short circuits, and malfunctions

when using EOL/2EOL/3EOL connection type

Depends on the connection type.

Power supply

MultiTransmitter power supply
