Section 4-4 Diagnostics

The LOGIQ™ 100 PRO System service diagnostics comprises of:
1.) Self test or power on diagnostics
2.) Service diagnostic tools
The self test or power on diagnostics are run every time the system is booted. The service
diagnostic tools include test procedures for testing the system at PCB level as well as block level.
The diagnostic tools provides a pop-up menu to enable selection of various tests to test various
blocks on the system.

Power On Diagnostics

The power on diagnostics or self tests are run every time the system is booted. This self tests
include testing the validity of the system software through EPROM checksum test and testing the
system RAM. It checks whether the keyboard and the trackball are properly interfaced to the
system. It also initiates the self test of analog subsystem. The two LED's and the beeper are used
to indicate error conditions.

Function
This LED indicates the scan lines,the DSP is scanning.The
LED glows when the cursor is moved in the B/M mode
This LED indicates the probe connect signal is good.This
indicates the FEB is Good
This LED indicates the B mode signal is given to the
display.The intensity of this LED is more during B mode.
This LED indicates the M mode signal is given to the
display.This LED glows during M and B/M mode,the intensity
of this LED is less during B/M mode
This LED is ON during Acoustic Frame measurement
switching.This also indicates the communication between the
DSP and the Davinci CPU FPGA
This LED indicates the Video Sync is happening.This indicates
the video frame output from the Davinci CPU to the monitor is
This LED indicates the KEY press on the keyboard.It glows
intermittantly when there is a key pressed.
This LED indicates the USB connection to the
Rearpanel.When a USB device or Pen drive is connected, the
LED glows to indicate it is to the Davinci CPU.(USB output of
the Davinci is Good)
