Appendix D. Plastic Enclosure

The plastic enclosure provides a secure way to protect your BL2100. The enclosure itself may be mounted on any flat surface.

The plastic enclosure itself consists of a base and a cover. The base alone is a convenient surface on which to mount the BL2100, and also provides a means to mount the BL2100 on any flat surface. The base and cover are sold together with an LCD/keypad module that plugs into the main BL2100 board.

Appendix D describes how to mount the BL2100 and the LCD/keypad inside the plastic enclosure, and provides details on mounting the assembly.

D.1 Assembly

1. Remove the RCM2200 module from the BL2100 main board, and set the module aside. The module will be plugged back in to the main board later.

2. Attach the BL2100 main board to the plastic enclosure base.

Position the BL2100 main board over the plastic enclosure base as shown below in Figure D-2. Attach the BL2100 to the base using the four 4-40 × ¼ screws supplied with the enclosure base.

3. Reconnect the RCM2200 or the RCM2300 module to headers J16 and J17 on the BL2100 main board as shown in Figure D-3. Be careful to align the pins over the headers, and do not bend them as you press down to mate the RCM2200 module with the BL2100 main board.

4. Install the LCD/keypad module (optional) as shown in Figure D-4. Be careful to align the pins over the headers, and do not bend them as you press down to mate the LCD/keypad module with the BL2100 main board.

5. Mount plastic enclosure (optional).

Use four #10 screws to attach the plastic enclosure to the surface on which it will be mounted. This step applies to production versions of BL2100 units once development has been completed.

6. Attach the enclosure cover to the base.

Position the cover over the plastic enclosure base as shown below in Figure D-5. Attach the cover to the base using the four 4-40 × 7/8 screws supplied.
