I am looking for a BB200 to purchase. This is the old style GPIO Button Board which is unavailable anymore. I have one but need another one so that I may test two units at once. If you have one you no longer use, please contact me and we can make arrangments to purchase it. Thanks and have a great day Will

  You can also visit http://www.hms-electronics.com. They make test boards for use with the brightsign as well.

  Thank you for the input.  Quick question, is there a way to yet to know whether the GPIO signal comes from the expander port vs. on board ports?
  I tried the GetSourceIdentity but then I would have to know the number of the unit which makes remote upgrades a problem.
  
  Again thanks for the input

  Yes, it's possible to know where it's coming from. In order to process gpios, you need to create a gpio object for the expander, and a separate gpio object for the on board ports. So, you could flag which object you received the input from to determine whether it's onboard or expander.

  I have created the objects for the expander and the on board, but am a little fuzzy on which command to use to determine which port it came from.  GetSourceIdentity is looking for a integer where as the object name is a text function.
  
  I know its simple but somehow its alluding me.
  
  Thanks for your input

  let's say you have this:
  
  onboard = createobject("roControlPort", "Brightsign")
external = createobject("roControlPort", "Expander-Gpio")

  
  
  Then, when you check the message, you're looking for something like this:
  
  If type(msg) = "roControlDown" then

if msg.GetSourceIdentity() = onboard.GetIdentity() then print "This is from the internal gpio"
If msg.GetSourceIdentity() = external.GetIdentity() then print "this is from the expander"

endif

  My apology for not returning this response sooner.  I was just able to sit down with my test units and test with the example code you gave me for determining which port the button press came from.
  
  I was able to create a program to test and then insert into an existing program for testing and it all works fine. 
  
  Thanks for your help with this and have a great day.
