  • Page 25: I/O Port

    DL-4 is part of an interconnected system composed of user devices that need to be synchronized with each other. For example, you could connect the DL-4 to an aerial camera in such a way that the DL-4 recorded its position whenever the shutter button was pressed. This port is not typically used for stand-alone applications.

    Cables are supplied to connect the receiver to a PC or modem. For further information on the signals, or connector pin-outs, for the serial ports or cables, please see Appendix A starting on Page 179. See Appendix B, Replacement Parts starting on Page 184, if you need to consult a list of NovAtel part numbers.

    PC for post-processing using the supplied DL4Tool software. DL-4 records raw data in the form of logs, which are written to the data file on a periodic basis. If you wanted to analyze the data in these logs yourself, the details of the logs are documented in Chapter 9, DL-4 Logs on Page 152.

  • Page 35: Schedule Logging Operation

    4.3.2 File Naming Conventions You can either provide a name for each data file in advance, or allow DL-4 to generate them automatically. 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-4's auto-generated names.

  • Page 36: Data Storage Requirements

    Should a conflict occur between an auto-generated file name or a file name specified in a scheduled entry, the DL-4 will resolve the conflict by creating a file name whose first character is a tilde ("~"), followed by a 7-digit random number, and a .PDC extension (e.g. ~9368412.PDC).

    This unique feature means that upgrading the firmware is equivalent to getting a DL-4 with an entirely different set of features. Upgrading can be done anytime, anywhere, without any mechanical procedures whatsoever. New firmware can be transferred to the DL-4 through a serial port, immediately making the unit ready for operation at a higher level of performance.
  • Page 58 To update your DL-4 receivers to the latest firmware follow the steps below. You must install WinLoad to complete these instructions: Connect your DL-4 to the COM1 port of your PC, but do NOT supply the receiver with power (do not install batteries or supply the receiver with external power).
  • Page 59 You will be prompted to make sure that the unit is powered off. At this point, make sure that the DL-4 is off and that you have not installed batteries or supplied the unit with external power. When you are sure the unit is not connected to a power supply, click <OK>.
  • Page 60 − OEM4 firmware WARNING!: Do not turn off power to the DL-4 or PC until the update/upgrade process is completed. If you do turn off power before WinLoad is finished, the DL-4 may need to be returned. When finished (approximately 5-6 minutes), you will once again be requested to power off the DL-4.
  • Page 61 WinLoad’s main window will read Script Completed Successfully.

    Choose a log output format from the Format list. The Raw option should be chosen for transmitting differential corrections. A log’s interval information is what determines when and how often the DL-4 receiver will collect that log’s information. For example, if the interval for the range measurements log (RANGECMP) is set to On Time 2, the receiver will log range measurements every two seconds.
