  • Page 8: Foreword

    FOREWORD Scope This manual provides sufficient information for the initial set-up and operation of the GPStation; its focus is on the user’s perspective for integration, evaluation, and operation purposes. It is beyond the scope of this manual to provide service or repair details.

    GPSAntenna. There is a LED above each serial port connector. If a LED glows red, data is being received by the GPStation on that port, while if a LED glows green, data is being transmitted by the GPStation on that port.

  • Page 12: Hardware Configuration

    2 – Hardware Configuration HARDWARE CONFIGURATION Installing the GPStation is a straightforward process. As shown in Figure 4, a minimum configuration is established with the following set-up: • Set up the GPSAntenna and optional choke-ring ground plane • Route and connect coaxial cable between the GPSAntenna and GPStation.

  • Page 13: Cable Connection Considerations

    The 501’s low-noise amplifier (LNA) boosts the power of the incoming signals by 23 dB to compensate for cable losses; if the losses are greater than this, excessive signal degradation will occur and the GPStation may not be able to meet its performance specifications.

  • Page 14: Antenna Cable Considerations

    It accepts a single input voltage between the range of +10 to +36 V DC. The power input is reverse polarity protected. Refer to the Power Requirements section of Appendix A for further information. The DC output of the autoranging AC/DC converter will meet the GPStation’s requirements for an input of 110 - 220 V NOTE: Operating the GPStation outside the specified input voltage range may result in damage to the GPStation, and/or unreliable data.

  • Page 15: Serial Data Cables

    AC plug SERIAL DATA CABLES Two serial data cables are supplied to connect the GPStation to a PC or modem. They are described as follows: • straight cable: 10-pin LEMO plug to 9-pin D-connector (DE9P plug); see Figure 6 & Table 2. This is used to connect the GPStation to a modem or radio transmitter to propagate the differential corrections.

    I/O STROBE PORT CABLE The I/O strobe lines can be accessed by inserting the 8-pin LEMO connector of the I/O strobe port cable (NovAtel p/n 01016330) into the I/O port. Figure 8 and Table 4 contain wiring and pin-out information on this cable. The other end of the cable is provided without a connector so that the user can provide an application-specific one;...

    NOTE: The accuracy of the OCXO is impaired by vibration and shock, so it is essential that the GPStation be at rest on a stable and secure surface during operation. The GPStation has rubber feet in order to reduce the effect of vibration.

  • Page 20: Operation

    OPERATION Before using the GPStation for the first time, ensure that you have set up your system as recommended in Section 2. The following instructions are based on a configuration such as that shown in Figure 9. It is assumed that a personal computer is used during the initial operation and testing for greater ease and versatility.

  • Page 21: Communicating Using A Remote Terminal

    NOTE: Although the GPStation can operate at bit rates as low as 300 bps, this may not always be desirable. For example, if several data logs are active (i.e. a significant amount of information needs to be transmitted every second) but the bit rate is set too low, data will overflow the serial port buffers and cause an error condition in the receiver status.

  • Page 22: Boot-Up

    Most valid commands do not echo a response to a command input; the indication that they have been accepted is a return of the port prompt from the GPStation. VERSION, HELP and ? are the only commands that provide a data response other than the port prompt.

  • Page 23: Dos

    The following example shows how the Windows 95 accessory programs Notepad and HyperTerminal can be used to create a hypothetical waypoint navigation boot-file on a PC, and send it to the GPStation. It is assumed that the PC’s serial port COM1 is connected to the GPStation’s COM1 port, and that a remote terminal is connected to the GPStation’s COM2 port.

    When you call, be sure to have available your GPStation model number, serial number, and program revision level. This information is printed on the original shipping box as well as on the back side of the GPStation itself. You can also verify the information by issuing the VERSION command at the port prompt.

    ASCII hexadecimal code, and the model# would be ASCII text Example: $auth 17cb,29af,3d74,01ec,fd34,gpstnm Once the $AUTH command has been executed, the GPStation will reboot itself. Issuing the VERSION command will confirm the new upgrade model type and version number. UPDATING USING THE “LOADER” UTILITY Loader is required (instead of the $AUTH command) when updating previously released firmware with a newer version of program and model firmware (e.g., updating a GPSTN Rev.

  • Page 27: Using The Loader Utility

    If you are running Loader for the first time, be sure to access the Setup menu (step 3 below) before proceeding to Program Card (step 4 below); otherwise, you can go directly from step 2 below to step 4. The procedure is as follows: Turn off power to the GPStation. Start the Loader program.
  • Page 28 When prompted by the program, turn on power to the GPStation. Loader will automatically establish communications with the GPStation. The time required to transfer the new program data will depend on the bit rate which was selected earlier. When the download is complete, use the terminal emulator in Loader (select Terminal), or any other one, to issue the VERSION command;...
