Figure 3-3 User Interface
3-2
All models are equipped with a fixed (non-user removable) Intellilink™
control center. The user interface includes a seven-line monochrome LCD
display (DM300c/DM400c) or an eight-line color LCD display (DM475), an
integrated full QWERTY keyboard, a numeric keypad, dedicated function
keys and software-defined "soft" keys.
Unlike some previous DM models, the user interface PCB does not include
any controller functions: it is a keyboard and display only. All controller func-
tions, including the PSD, are resident on the system's main logic board. See
section 3.6, PCBs, Controller (Main Logic) Board, for more information.

The user interface is menu driven and offers a full range of features based
on the common DM Series system architecture. It allows the user to per-
form meter refills, store information related to indicia printing under a specif-
ic key, set postage value, and perform all user entry requirements. See the
Control Panel Unit in section 3.6 for a description of the user interface PCB.

LED States

The LED on the user interface (figure above) has three states:
• Green: system is nominal (normal operating) mode.
• Orange: system is in sleep mode.
• Red: system fault.
The LED flashes green several times during initialization.
