The DIU 200 improves door security, by allowing the installer to locate lock  
controls on the secure side of a door, with an intelligent CEM reader on the

will instruct the DIU (over the RS485 communications channel) to activate the  
appropriate output to release the lock using a coded data signal (i.e. coded lock).
