  • Page 3: Preface

    EndRun Technologies has been dedicated to the development and refinement of the technologies required to fulfill the demanding needs of the time and frequency community since 1998. The instruments produced by EndRun Technologies have been selected as the timing reference for such rigorous applications as computer synchronization, research institutions, aerospace, network quality-of-service monitoring, satellite base stations, and calibration laboratories.

  • Page 4: About This Manual

    Extended Warranty EndRun products are very reliable and rarely need to be returned to the factory for service. After the initial warranty period it is most cost-effective for the customer to repair the unit on an “as needed ba- sis”, rather than pay for an extended warranty or the annually recurring fees of a service contract..

  • Page 5: Warranty Repair

    If the warranty period has expired, we offer repair services for equipment you have purchased from EndRun. Call and ask for a customer service agent. It is important to contact us first as many prob- lems may be resolved with a phone call. Please have the serial number of the unit and the nature of the problem available before you call.

  • Page 17: Chapter One - Introduction

    "Smarter Timing Solutions" Chapter Introduction This chapter introduces the GPS-Synchronized Sonoma Network Time Server and gives a brief over- view of what it is and how it works. What It Is The Sonoma Network Time Server is a precision server of Coordinated Universal Time (UTC) that can be connected via an Ethernet port to any TCP/IP network.

  • Page 18: Gps Receivers

    EndRun developed a timing optimized GPS receiver for additional resilency, accuracy, and reliability. The EndRun GPS Receiver strictly complies to the IS-GPS-200 specification. and began shipping in Sonoma in June 2017. GPS receiver specifications are listed in Appendix H - Specifications.

  • Page 19: Where To Use It

    Where to Use It Since signals from the GPS satellites are available at all locations on the globe, you may deploy the Sonoma virtually anywhere. However, you must be able to install an antenna either on the rooftop or in a window so that satellite transmissions may be received at least several times during the day. For more information see Appendix E - Installing the GPS Antenna.

    Sonoma has dual power supplies, then multiple power cords may be installed. To de-energize this equipment, disconnect all power cords from the device. Do not install the Sonoma N12 where the operating ambient temperature might exceed 122°F (50°C). Connecting the Optional DC Power The DC Power Input is an option.

    NOTE You must use an RS-232 null-modem cable or adapter if you are connecting the Sonoma N12 to another computer. The cable included in the shipping kit is a null-modem cable. If your computer does not have a serial port, you can use a USB port with a USB-RS232 converter similar to Gearmo GM-FTDI-8.

The last sections contains information on a window-mount installa- tion and on obtaining a GPS reference position. Antenna Location The location of the antenna must be chosen based on having as clear a view of the sky as possible.

    • 50 feet of RG-59U (Belden 9104) Cable/TNC Male In June 2017, EndRun changed the GPS antenna model that shipped with the time server. A drawing of the GPS roof-top installation for the two different antennas is shown at the end of this appendix in Figures 1A and 1B.

  • Page 147: Long Cable Runs

    Most GPS Time Servers are installed with only 50 feet (15 meters) of antenna cable. However, there are many circumstances where 50 feet is inadequate. EndRun can accommodate a cable length of up to 1000 feet using a combination of low-loss cable and preamplifiers.

  • Page 148: Using Three Preamplifiers

    Signal splitters are used when two time servers are sharing one antenna installation. The smart GPS Splitter supplied by EndRun is a one-input, two-output device. In the normal configuration, one of the splitter RF outputs (J1) passes DC from the connected GPS Receiver through the splitter to the antenna, allowing the GPS Receiver to power both the antenna and the splitter amplifier.

  • Page 149: Calibrate Your Receiver

    3. The signal splitter supplied by EndRun has a built-in preamplifier to compensate for signal loss through the splitter. If using a splitter other than the one supplied by EndRun you may need to com- pensate for splitter signal loss by using a separate GPS preamplifier.
