Sigma 1U643 Cable Box User Manual


 
1. INTRODUCTION
The 1U643 Breakout Box and Data Logger is a tool for monitoring aircraft systems by
providing a test point breakout between various electronic modules and their associated
interconnects with the aircraft. The 1U643 was designed as a dual purpose tool. The 1U643
can be used stand alone as a normal breakout box or, when connected to a notebook
computer via the RS232 serial port, as a data viewing, logging, and recording instrument.
At the heart of the 1U643 electronics is the industry standard 80C552 processor which
when connected to a notebook computer via RS232 serial communications becomes a very
powerful diagnostics tool. The 1U643 data logger allows diagnosis of aircraft system
malfunctions by enabling the user to record data from aircraft systems for later viewing by
knowledgeable systems engineers or technicians.
