NI 6251digital channels configuration

[nawaf.93]

hi there 

I am using pci 6251 by simulink and it shows that my device has 48  while the physical digital channels are DI<0..7>,DO<0..7>,WR ENABLE,LATCH,GLB RESET,RD ENABLE and ADDRESS <0..3>.

I looked in the manual and I only found a table(shown below) that identify analog channels.

Is there any table describes how are the 48 channels are mapped to the DAQ device ?

NI ELVIS Input Channel	DAQ Device Input Channel
ACH0+	AI 0
ACH0–	AI 8
ACH1+	AI 1
ACH1–	AI 9
ACH2+	AI 2
ACH2–	AI 10
ACH3+	AI 3
ACH3–	AI 11
ACH4+	AI 4
ACH4–	AI 12
ACH5+	AI 5
ACH5–	AI 13
AISENSE	AI SENSE
AIGND	AI GND

Thanks

Hi Nawaf.93,

What DAQ device are you looking to use with the PCI 6251? Each device has a unique set of specifications and channel arrangement, so knowing the exact device would be helpful in getting you some more information.

I have also found the specifications for the NI PCI-6251 in case you would like to reference it: http://www.ni.com/pdf/manuals/375213c.pdf

Thank you Andrea.W so much for replying.

I'm using ni elvis as indicated in the table and I attached a picture of it

Hi again,

The NI-ELVIS connects to the pci card through the desktop computer, and some more information about how to get started with this device can be seen here: http://www.ni.com/pdf/manuals/374628c.pdf

I also found the NI-ELVIS device pinout from documentation on our website. It shows each pin and what it corresponds to: http://download.ni.com/pub/gdc/tut/elvis_ii_proto-board_pins.pdf

I hope this helps!

Regards,
