  • Page 9: Notice

    Do not eject the PC Card while the DL is logging data, as you may lose part of or your entire data file. The DL can accept an input supply voltage in the range +10.7 to +18 V DC. This may not be the same range as other NovAtel products with which you are familiar.

  • Page 10: Foreword

    The following may provide you with additional valuable reference information: • SoftSurv User Manual - a description of the SoftSurv suite of GPS surveying programs and utilities. SoftSurv and DL are complementary products designed to work together. SoftSurv software provides a user-friendly graphical interface to the DL, allowing you to focus on your work without needing to learn about the MiLLennium’s commands and logs.

  • Page 13: Operating Modes

    • Manual Operation: Among other things, a host computer can transmit scheduling and logging parameters, receive collected data, and turn the DL on or off. In this mode, the DL does not need to be tracking satellites, or even have an antenna connected to it.

  • Page 14: Accessories And Options

    The NovAtel DL can be used with the following accessories: • SoftSurv software – a suite of programs that allows you to plan your data collection trip, configure your DL or handheld data logger, post-process your collected data, and archive your information sets •...

  • Page 15: Set Up

    SETTING UP AT THE OFFICE Figure 2 displays how you might typically set up the DL at the office – for example, to load a schedule, or to transfer collected data to a PC. In this situation, the PC is connected to the COM1 port, and energy is supplied by means of an AC/DC converter that is connected to the Power port.

  • Page 16: Setting Up In The Field

    Mount or place the DL on a secure, stable structure that will not sway or topple. For example, attach the DL to a tripod leg using the optional mounting bracket (see Figure 14: Mounting Bracket and Figure 15, Appendix I).

  • Page 17: Choose The Right Antenna

    Insert a PC Card into the DL (see Using the Removable Flash Memory Card, Page 23). Connect the output of a power source (e.g. battery) to the input power port of the DL (see Power Port & Cable, Page 22). Once power is supplied, the DL turns on automatically, begins an initialization sequence, and then enters low- power mode.
  • Page 18 WARNING: While there may be other antennas on the market that might also serve the purpose, please note that the performance specifications of the DL are guaranteed only when it is used with a NovAtel model 531 (L1) or model 502 (L1/L2) GPSAntenna.

  • Page 19: Connect Cables

    Figure 4: Close-up of Ports on Rear End-cap Each connector is keyed to ensure that the cable can be inserted in only one way, to prevent damage to both the DL and the cables. Furthermore, the connectors that are used to mate the cables to the DL have a locking mechanism that requires careful insertion and removal.

  • Page 20: Serial Ports & Cables

    For example, you could connect the DL to an aerial camera in such a way that the DL recorded its position whenever the shutter button was pressed. This port is not typically used for stand-alone applications.

  • Page 21: Peripheral Power Supply Via Com2 Port

    Good-quality cable introduces lower losses than low-quality cable. If the cable loss becomes too great, excessive signal degradation occurs and the DL may be unable to meet its performance specifications.

    (if available) without any interruption in its logging activities. Consider the case where the DL is connected to two 12 V DC batteries. As described in Table 4, Page 26, as the voltage drops on the first battery, the Power indicator color changes from green to amber, then to red. Warning messages are sent on the serial port indicating that battery power is becoming exhausted (see the description of the LPSTATUSA log, Page 73 and MSGA log, Page 75 if you require further information).

  • Page 23: Using The Removable Flash Memory Card

    Improper selection of wire gauge can lead to an unacceptable voltage drop at the DL. A paired wire run represents a feed and return line; therefore, a 2-m wire pair represents a total wire path of 4 m. For a DL operating from a 12 V DC battery system, a power cable longer than 2.1 m (7 ft) should not use a wire diameter smaller than that of 24...

  • Page 24: Opening The Cover

    In this case, do not force the card! Remove it, orient it properly, and then insert it. After the card is locked in place, close the cover again. Figure 7: Handling the PC Card DL™ User Manual Rev 3...

  • Page 25: Sleep, Power Down And The Power Switch

    DL monitors its serial ports, and becomes fully operational a short while after as serial port activity is detected – for example, if a key is pressed on a handheld data logger that is plugged into one of the DL’s serial ports. The time required to wake up is only a few seconds, but it may require an additional few minutes to initialize the GPS receiver and allow it to establish an initial time and position.

  • Page 26: Status Indicators

    Power off or PC Card not detected, or initialized. When the DL is connected to an AC/DC converter, the Power indicator may be ignored as long as the color is green; if it turns red, then you should investigate whether there is a problem with either the AC supply or the converter itself.

  • Page 27: Using The Dl

    3 – Using the DL 3 - USING THE DL Before using the DL for the first time, ensure that you have followed the installation instructions of Chapter 2 - Set Up, Page 15. See CAUTION!, Page 9, for a list of items of which you should be aware as you use the DL.

  • Page 28: Communications With The Dl

    DL records raw data in the form of logs, which are written to the data file on a periodic basis. NovAtel’s SoftSurv post- processor automatically interprets these logs and the data that they contain. If you wanted to analyze the data in these logs yourself, the details of the logs are documented in Appendix F - DL Logs, Page 64 of this manual.

  • Page 29: Schedule Logging Operation

    You can only provide a file name when you are scheduling a single data collection event. If you are scheduling a series of events, you have to accept the DL’s auto-generated names. An acceptable file name consists of a base of up to eight characters, followed by a .PDC extension.

  • Page 30: Data Storage Requirements

    Session ID assigned in sequence (0 .. 9, A .. Z) based on the presence of files previously logged on a particular day. For example, a DL might have a serial number such as CGN95450087. A date such as January 25 has an UTC day-of- year representation of 025. The 15 schedule of the day would have an entry index of E.

  • Page 32: Firmware Upgrades & Updates

    This can be done anytime, anywhere, without any mechanical procedures whatsoever. New firmware can be transferred to the DL through a serial port, immediately making the unit ready for operation at a higher level of performance. This also prevents rapid obsolescence.

  • Page 33: Updating Using The "Loader" Utility

    You must first acquire the latest firmware revision, which comes as a file with a name such as OEMXYZ.EXE (where XYZ is the firmware revision level). This file is available from NovAtel’s FTP site (ftp.novatel.ca), or via e-mail (support@novatel.ca). Alternately, the file can be mailed to you on floppy disk.
