Appendix B. Plastic Enclosure

The plastic enclosure provides a secure way to protect your BL2000. The enclosure itself may be mounted on any flat surface.

Appendix B describes how to mount the BL2000 inside the plastic enclosure, how to install the optional light pipes, and provides details on mounting the assembly.

B.1 Assembly

1. Attach the BL2000 to the plastic enclosure base.

Position the BL2000 over the plastic enclosure base as shown below in Figure B-1. Attach the BL2000 to the base using the two 4-40 × ¼ screws supplied.

2. Install light pipes (optional).

Light pipes are included in the tool kit to facilitate seeing the LEDs on the BL2000 board once the enclosure is assembled.

With the enclosure top positioned as shown in Figure B-2, insert the eight light pipes into the slots identified in Figure B-2. Position the light pipes snugly against the enclosure top since there is little clearance between the light pipes and the LEDs on the BL2000. The light pipes "snap" in place. Verify that the light pipes are aligned over the LEDs, then apply a drop of cyanoacrylate or contact cement to the inside of the enclosure around each light pipe to hold it in place.

NOTE	Once the glue is applied, it will not be possible to change the alignment of the light pipes without damaging the plastic enclosure.

3. Attach the enclosure top to the base.

Position the enclosure top over the plastic enclosure base as shown below in Figure B-3. Attach the enclosure top to the base using the two 4-40 × ½ screws supplied. If you installed the light pipes, be sure they are aligned over the LEDs as shown.

4. Mount plastic enclosure (optional).

Use four #10 screws to attach the assembled plastic enclosure to the surface on which it will be mounted. This step applies to production versions of BL2000 boards once development has been completed.

B.2 Dimensions

Figure B-4 shows the dimensions for the plastic enclosure.

Figure B-4. Plastic Enclosure Dimensions

When fully assembled with the BL2000 installed, the total height of the plastic enclosure will be 1.1" (28 mm).
