2-1.1 Micom-Z Dash-Mount Version
2-1.1.1 Structure
Figure 2-1 shows the structure of the Micom-Z dash-mount version. Micom-Z dash-mount version
consists of two main assemblies, attached by means of four screws:
• Body assembly. The body assembly includes two main modules, LORD and HI POWER,
interconnected by a few cables. The LORD module is actually an assembly protected by a shield
that also carries the optional GPS receiver and a backup battery for protecting the operational
parameters. The external connectors are located on the two modules, but are attached to the rear
panel, for physical support. The LORD and HI POWER modules can be accessed after opening
the top cover (not shown in Figure 2-1), and separating the front panel assembly (it is not
necessary to remove the rear panel, but connectors must be released from the panel before it is
possible to extract the modules).
• Front panel assembly. This assembly includes the operator interface (controls, keypad, LCD), a
microphone connector, an internal speaker, and the CONTROL HEAD module. The front panel
assembly is connected to the LORD module by a single flat cable.
