3.1.1. ARM BOARD: 500 AND 700 MODELS
The display contains only one board which comprises the CPU, an ARM microprocessor, its logic
circuits and a FLASH EPROM containing the operating program for the machine moreover, acts as
the interconnection hub for all the components of the display and serves as the point of connection
with the low kit driver.
The main functions of the board are:
• Manages and process signals from:
 Keyboard;
 HR Receiver (500 LED);
 HS/HR receiver (700 LED);
 C-safe board;
 Emergency button.
Optional:
 Dual TGS reader.
• Distributes the voltages received from the low kit driver;
• Exchanges, over the RS-485 serial link to the driver box, commands for controlling the belt and
elevation motors;
• Exchanges, over the RS-485 serial link to the driver box, commands for controlling emergency
signals;
• Controls the LEDs and the 7-segment displays which provide feedback about the exercise
session.
The board includes the following indicator LEDs:
