[/b][/size]Dear Sir

I am using TURBO PMAC PCI Lite with analog DAC signals.

i want to isolate analog circut isolation/input flag supply/AENA supply control. Currently i am taking all supplies from pc bus.

 

 

i want to isolate

 

1) INPUT FLAG SUPPLY CONTROL:-If E90 connects pins 1 and 2 and E89 is OFF, the input flags are supplied from a separate A+V supply through pin 9 of the J9 JEQU connector.

 

IS IT OK???

 

2) AENA/EQU Supply Control :If E100 connects pins 2 and 3, the circuits will be supplied from a separate A+V supply brought in on pin 9 of the J9 JEQU connector.

 

IS IT OK???

 

3) Analog Circuit Isolation Control

E85, E87, E88 are off and The positive supply (+12 to +15V) should be brought in on the A+15V line on pin 59. The negative supply (-12 to -15V) should be brought in on the A-15V line on pin 60. The analog common should be brought in on the AGND line on pin 58.

 

please confirm whether it is ok as in diagram on page 5 in manual it is showing J7 connector and J9 is connected ie connection under j9 is showing crossing only.please check and confirm.

 

regards
