  • Page 6: What Is The Db-100

    Multiple studies can be stored in the DB-100, using up to a total of 312 intervals of data. For each count, the unit stores the date and time, the number of intervals used, a site code, and the data.

  • Page 7: Maintaining Your Db-100

    Programming the DB-100 The DB-100 is simple to use. An OFF/ON switch on top of the unit panel is used to turn the unit on and off. A 4-line by 20-character display helps you select the proper entries. All options are clearly displayed, with the cur- rently selected option shown with a blinking highlight.

  • Page 8: Using The Count Keys

    Since the DB-100 looks like an intersection, doing a count is very intuitive. If a car makes a left turn from an approach, you simply push the button that shows a left turn from that direction.
  • Page 9 Chapter 1 — Introduction to the DB-100 bol is included to suggest that you align the counter so that buttons 1 though 4 faces north while you are doing the count. It is not necessary to always conform to this practice. Sometimes it is more convenient for you to face another direction when you do the count, especially if you want to be able to read the display.

    You have three sub-menus from which to choose: Tests, Time/Date and Beeper. Tests The DB-100 is designed to be a very reliable instrument. It is manufac- tured with high quality components, and is designed to withstand rugged use in the field. It is also a very sophisticated product with a microprocessor “brain”.
  • Page 23 DO. Memory Test The DB-100 contains low-power solid state memory that is used to store the data from the various counts. Solid state memory is extremely reliable. However, like any electronic element, it can go bad.

  • Page 25 Serial Port The DB-100 has an RS-232 serial port that is used to transfer its data to your computer for analysis. The serial port has bi-directional capability, meaning that data can be sent out to the computer and commands can be received in from the computer.
  • Page 26 The port itself also has small numbered labels for each pin. The DB-100 sends a series of known messages out of the serial port, and at the same time reads the messages coming into the serial port.

    Modem Transfer to a Computer The DB-100 has a special option that allows you to transfer the data to your office computer using a portable modem. This feature is useful if it is difficult or inconvenient for the field people to bring the DB-100 to the office to dump the data.

    Once the connection is made, a signal must be sent back to the DB-100 to tell it to begin the download. This signal is one character, a capital ‘S’. After this signal is sent back to the DB-100, the data transfer will begin and the screen shown below is displayed.
