8.3 Technical Description
Introduction
The local control panel is built around a PIC16C55, an EPROM-Based 8-Bit CMOS Microcontroller with hardware selectable en-
hancements. The difference between I1 and I3 is that the first is a classic through component and the second is a SMD PIC processor
version.
The local keypad is the integrated control device of the projector.
Depending on the key that is pressed, an RC5 code is generated. This code is sent to the CPU-board, which converts the code to
projector commands.
A character based LCD display (24 characters by 2 lines) can be connected to the unit. This LCD is used for displaying menu’s and
error messages. The CPU-board can control the display through an I²C I/O expander.
