Hello,

I would like to have my satellite receiver trigger recording network news 
through a relay contact closure.  I installed the PCI-DIO24 card and have it 
configured with 2.2K pull-up resistors to keep all contacts "on" in the default 
position.  When a relay contact closes on the the satellite receiver, it pulls 
the lines "Down" to ground, thus pulsing the PCI-DIO24 to "Off".   This is 
contrary to standard practices for GPI's in general and could pose some 
problems.


What I am curious is in the configuration for recording - does the GPI setting 
to start/stop recording respond to changes in state, or does it require an "On" 
pulse to start the recording and an "Off" pulse to stop.   


It it is the latter, I will need to figure out some solution (preferably in 
software) to address.   A couple of options would be to modify the driver code 
to invert all behavior for the card.  Alternately, an option could be added to 
the GPI configuration in Rivendell to invert all GPI selections on the card 
globally such that these cards could have On and Off swapped.  


Looking for experience and suggestions....


Thanks.
Brian
