Datasheet

Communication Establishment method :
To establish the communication between computer and unit we have a loop in our
computer program which requests device ID continuously and when ever it receives the
Device ID from unit, computer understands the device Model and handles the data
accordingly. This makes sure that both computer and unit are ready to communicate and
synchronization is completed.
We have used this method to synchronize and then to lock the keyboard before further
communication ( since Unit is not intended to accept commands from computer only till
it is in computer interface mode. During this time keyboard will not function). When
Keyboard is locked by computer the unit will display “Remote Locked” and it will
remain in Remote communication till it is not unlocked by the connected computer.
Hence it is very important to include the ‘unlocking command’ in the ‘application close
procedure’ otherwise unit will not function normal even if communication cable is
removed.
