Add IO Sample Method to 9203 and other Pipelined Cards

Status: New Submitted by on 02-21-2011 08:22 AM Comment

The IO Sample Method for the 9205 is very useful in that it can tell the card what channel to scan from two samples ahead, putting the appropriate sample into the pipeline to be read from. Without this method, if one wants to switch channels, the two samples currently in the pipeline will have to be discarded, adding conversion time. With the IO Sample Method, it allows users who know what future samples they want to request to keep up the maximum conversion rate.

MAX access and configure I/O module

Status: New Submitted by Active Participant on 07-30-2010 03:36 PM Comment

The access to configure the cRIO modules can only be made within the LabVIEW's project window. It would be very nice if we could do it trough MAX (Measurement & Automation Explorer).

Manchester Enable Clocking

Status: New Submitted by Member on 05-28-2010 12:22 PM 1 Comment

I am looking for a way to transmit 9 bit Address array  17 bit Data Array in a Manchester Format. I am using a PCI-7813R  with SCB-68 Interface. I have breadboarded the push pull circuit to generate the +/-5V Signal. 

 

 

NI has to link to Manchester enable encoding.

http://decibel.ni.com/content/docs/DOC-2824

 

2nd link mentioned about half bytes and update output state that I do not have an understanding of.

 

The Problem is since Labview does not work like a Hardware Clock. The Clock in my program does not transition a full period during the iteration. Thus the output is wrong.   I have tried Global variables without any success.

 

I am trying to duplicate the DOC-2824 picture of Manchester Enable Communication.

 

 

My Code  is attached.

 

 

 

Any assistance would be appreciated.
