After a power on reset, console output should appear as showin in Figure 26 console interface:
(c) 1993 Nemesys Research Ltd. Device Version 200.0 Firmware Version 1.1 I2C Driver Init... OK Xilinx Init... OK ATM Init... OK SAA7191 Init... OK SAA7186 Init... OK C-Cube Init... OK AD1848 Init... OK Timer Init... OK Protocol Init... OK Scheduler Init... OK
Figure 26: AVA200 Power On Diagnostics.
When the ATM transmission interface is in violation (indicated by the Blue LED permanently on), it is normal for the console output to stop when the ``Protocol Init'' stage is reached. As soon as the violation is cleared console output should continue.
During normal operation of the unit, console output should contain messages of the following form:
Proto: Bad cell
Cell Rx: 01DEADBEEF0102030405060708090A0B0C0D0E0F10111213141516

Proto: Reset FFFF00000080
Proto: Duplicate cell
Proto: Video 0A
Proto: Audio 01

Pressing any key will cause the scheduler to be exited and the AVA200
Debug Monitor to be entered. The prompt ``>
'' will be
displayed. The AVA200 Debug Monitor will display a list of the currently
acceptable commands whenever the ``?
'' character is typed.
The main menu should appear similar to Figure 27.
