Hi,
 
	 
 
	Its me again:-)
 
	 
 
	Ive tried to add an extra keypad to my Flex 20. I have it at address 4, but looking at the system I have a keypad at 10, 50 and 19. The keypad at 19 is showing as 0% comms.  If I remove keypad 0 and replace it with the suspect one with address set to 0 it works fine.
 
	 
 
	Anybody get any ideas, I wonder if me plugging it in with different addresses has gone over the 4 keypad limit on the Flex 20??
 
	 
 
	Thanks,
 
	 
 
	Ian.
