    These limits apply over the range of 30–230 MHz. The limits are 7 dB higher for frequencies above 230 MHz. Although the test range goes to 1 GHz, the emissions from Rabbit-based systems at frequencies above 300 MHz are generally well below background noise levels.

  • Page 13: Design Guidelines

    • When connecting the BL2100 single-board computer to outdoor cables, the customer is responsible for providing CE-approved surge/lighting protection. • Rabbit recommends placing digital I/O or analog cables that are 3 m or longer in a metal conduit to assist in maintaining CE compliance and to conform to good cable design practices.

  • Page 15: Chapter 2. Getting Started

    2. G ETTING TARTED Chapter 2 explains how to connect the programming cable and power supply to the BL2100. 2.1 BL2100 Connections 1. Remove the RabbitCore module from the BL2100 main board, and set the module aside. The module is removed to allow access to the mounting holes on the main BL2100 board, and will be plugged back in to the main board later.
  • Page 16 The plastic enclosure base is offered as a separate option when individual BL2100 boards are purchased. NOTE: Appendix D, “Plastic Enclosure,” provides additional information and specifications for the plastic enclosure. Smartcat (BL2100)
  • Page 17 3. Reconnect the RabbitCore module to headers J16 and J17 on the BL2100 main board it was removed from earlier as shown in Figure 4. Be careful to align the pins over the headers, and do not bend them as you press down to mate the module with the BL2100 main board.
  • Page 18 NOTE: Some PCs now come equipped only with a USB port. It may be possible to use an RS-232/USB converter with the programming cable supplied with the Tool Kit. An RS- 232/USB converter (part number 20-151-0178) is available through the store. Note that not all RS-232/USB converters work with Dynamic C. Smartcat (BL2100)
  • Page 19 5. Connect the power supply. First, prepare the AC adapter for the country where it will be used by selecting the plug. The BL2100 Tool Kit presently includes Canada/Japan/U.S., Australia/N.Z., U.K., and European style plugs. Snap in the top of the plug assembly into the slot at the top of the AC adapter as shown in Figure 5, then press down on the spring-loaded clip below the plug assembly to allow the plug assembly to click into place.

  • Page 87: Contrast Adjustments For All Boards

    C.2 Contrast Adjustments for All Boards Starting in 2005, LCD/keypad modules were factory-configured to optimize their contrast based on the voltage of the system they would be used in. Be sure to select a KDU5V LCD/keypad module for use with the BL2100 — these modules operate at 5 V. You may adjust the contrast using the potentiometer at R2 as shown in Figure C-3.

    C.5.1 Programming Cable Tips Once the LCD/keypad module is in place on the BL2100, it is not possible to remove or attach the programming cable to/from the BL2100 programming port. You will have to remove, or at least lift up, the LCD/keypad module while you connect or disconnect the programming cable.
  • Page 92 Once you have finished programming the LCD/keypad module, you should disconnect the programming cable from the BL2100 programming port, remembering to first remove, or at least lift up, the LCD/keypad module, disconnect the programming cable, and finally mount the LCD/keypad module back firmly on the BL2100 main board.

  • Page 93: Bezel-Mount Installation

    C.6 Bezel-Mount Installation This section describes and illustrates how to bezel-mount the LCD/keypad module designed for remote installation. Follow these steps for bezel-mount installation. 1. Cut mounting holes in the mounting panel in accordance with the recommended dimen- sions in Figure C-11, then use the bezel faceplate to mount the LCD/keypad module onto the panel.
  • Page 94 Do not tighten each screw fully before moving on to the next screw. Apply only one or two turns to each screw in sequence until all are tightened manually as far as they can be so that the gasket is compressed and the plastic bezel faceplate is touching the panel. Smartcat (BL2100)
