Meinberg product. Each of the chapters addresses a specific topic such as how the GPS183SV operates in general, how to correctly install it, and the key technical specifications of the device. This Setup guide also describes the main configuration operations needed to quickly get your product up and running.
7.2 Pulse and Frequency Outputs The pulse generator of GPS183SV generates pulses once per second (P_SEC) and once per minute (P_MIN). Additionally, master frequencies of 10 MHz, 1 MHz and 100 kHz are derived from the OCXO. All the pulses are available with TTL level at the rear connector.
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.

Meinberg provides suitable cable types with its antennas and these are ordered together with the antenna to match the length you need from your antenna to your Meinberg reference clock. The route to be covered for your antenna installation should be determined and the appropriate cable type selected accordingly before confirming your order.

Compensating for Signal Propagation Time The propagation of the signal from the antenna to the receiver (reference clock) can incur a certain delay. This delay can be compensated for with Meinberg Device Manager Software. The signal propagation time can be compensated for by entering the length of the antenna cable under "Settings...
Please refer to the standards regarding antenna installations (e.g., DIN EN 60728-11) for more information. However, in order to preserve the safety of the building and to protect your Meinberg system, Meinberg recomends the use of the MBG-S-PRO surge protector, which is addressed in more detail later in this chapter.

Optional MBG S-PRO Surge Protector Information: The surge protector and suitable coaxial cable are not included as standard with a Meinberg GPS Antenna, but can be ordered as an optional accessory. Construction The MBG-S-PRO is a surge protector (Phoenix CN-UB-280DC-BB) for coaxial connections. It is patched directly into the antenna line and consists of a replaceable gas discharge tube that redirects the energy from the cable shielding to the ground potential when ignited.

Meinberg system in order to prevent destructive potential differences. Connect the coaxial cable from the antenna to one of the surge protector connectors, then connect the other surge protector connector to the coaxial cable leading to the Meinberg reference clock. Caution!
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.
