Radio controlled module FUM xxx
The radio controlled module is a small PCB-module generally designed and developed to receive and decode time signals. Its internal time is based on the decoded and checked time information, available at the output pin X4 (RS232-OUT).
The radio controlled module is able to communicate with a host PC via a serial interface: the corresponding command set is described in the datasheet. A completely checked time and state information is available at the output. The radio controlled module FUM xxx u is including the state message from an embedded power supply controller.
The start of a time signal reception is automatically managed by the internal software, it also can be initiated by an external command.
