    Transmission speeds, framings and mode of operation can be configured separately using the setup menu. COM0 is compatible with other radio remote clocks made by Meinberg. It sends the time string either once per second, once per minute or on request with ASCII ´?´ only. Also the interfaces can be configured to transmit capture data either automatically when available or on request.

  • Page 44: Power Supply

    8.3 Power Supply The power supply used with a GPS183SV has to provide only one output of +5V. The output voltage should be well regulated because drifting supply voltages reduce the short time accuracy of the generated frequencies and timing pulses. The power supply lines should have low resistance and must be connected using both pins a, b and c of the rear connector.
