Where is the physical location of CPULL Pin 40 on the PCI-6533 for +5V Conn.

[jlacy]

Where is the actual physical location to solder a wire to CPULL so that pin 40 is tied to +5V, pin 1.   It looks impossible to get wire onto the actual connector without damaging the board or connector and I don't see any lands tied to them? Can you provide a diagram or picture indicating the physical location on a PCI-6533 ? I need CPULL tied to +5V so that when computer is powered off, the motherboard still provides the +5V to the control lines.  Otherwise I get all digital outputs turning on when the PC loses power.

Thanks,

Hi,

Thank you for posting to the NI forums.  Are you considering soldering the CPULL line directly on the PCB?  Keep in mind that this will void any warranties the device may still have, and NI will not be able to repair it (whether it’s a related problem or not) after a modification like that.  Instead, I would strongly recommend just modifying the terminal block to which the 6533 is connected.  Which terminal block are you using with the device? 

You can just connect the leads to the terminal block’s pins (40 and 1).  This will protect the 6533 device from any damage that it may have incurred otherwise from the soldering iron.

I hope this helps.  Please post back if you have further questions.

I don't have a terminal board. It is plugged directly into a Dell PC which is cabled with a 68pin to 50 pin adapter to my interface adapter.  So,  I guess that answers my question. I have now found out that I must purchase an external terminal board adapter to plug the 68pin connector into, then make my mod. on that board and run a cable from the adapter to my interface chassis.  Sure would have  been nice if NI had included jumpers on the pcb.  Thanks.
