Install Communications Module
onto Microcontroller Board
Equipment needed: Wrist grounding strap
Phillips screwdriver (#2)
Small flat blade screwdriver
1. Before installing the communications module, set up the hardware wiring
for the application. See Chapter 4 for details.
2. With power off, loosen two front screws, and remove them.
3. Slide the chassis out of the case by pulling firmly on the bezel. Do not de-
tach the board assembly form the front face of the controller.
4. Orient the Communications Module as shown, and attach it to Connectors
P1 and P2 as shown in Figure 4.4.
5. To reassemble the controller, properly orient the chassis with board open-
ing on top. Align the circuit boards into the grooves on the top and bottom
of the case. Press firmly on the front face assembly until the chassis is all
the way into the case.
If it is difficult to slide the chassis in all the way, make sure the screws have
been removed (they can block proper alignment), and that the chassis is
properly oriented.
6. Carefully insert and align screws. Tighten them until the bezel is seated firmly
against the gasket. Do not overtighten.
