Engineering parameters radio controlled modul MSFu- FUM MSFu

The radio clock module MSF U is a very small module onto a PCB whose main operational area is the receipt and the Dekodierung of the MSF time signal. The decoded and checked time information forms the internal time base for the module and is provided at the module exit X4 (RS232 out). The radio clock module is able to communicate above a serial interface with any host computer. The imperative described in the operating instructions serves for it. Above this serial interface completely checked time or status information is available to the connected host computer thereby any time.

The radio clock module begins radio receipts to the synchronisation with the MSF signal automatically several times during the day. Additional receipt attempts can be initiated on requirement by the connected host computer or by use of an optionally to be connected operating key. The radio clock module MSF U disposes of a power supply controller which supervises the power supply and spends with undervoltage a signal in the protocol.
For a successful application the radio clock module must be connected with a balanced aerial, the serial interface of a host computer (with suitable level recorder adaptation) and the care tension.
