OK. Now, Timing/ADC/DAC are working. It's almost there.
1) As a temporaly clock, I put a function generator at the back side of the ETMY.
Set it to the rectangular +/-4V@16384Hz. Connect it to D060064 PCIX Timing Interface Board in the IO Chasis.
That is a line receiver to feed the TTL signal into ADCs/DACs.
I confirmed the actual sampling clock is supplied to the ADC/DAC boards by looking at the SMB output of the D060064.
2) Restarted the realtime code.
3) I looked at DAC output by putting 5000,10000,15000,20000,25000cnt to UL/UR/LR/LL/SD coils again.
Yes! I could see the DAC channels are putting DC voltages.
4) Then I connected DAC CH0 to ADC CH0 using SCSI breaking up boards.
Yes! I could see the coil output switching change the ADC counts!
Now, we are ready to see the suspension damped. Check it out.
