ANSWER BACK CODE

Programming the answer back codes of the 6 position electronic key-lock is

also very easy as they are included in the keyboard programming with the locations

coded as “KLP”, “KL0”, “KL1”, “KL2”, “KL3” and “KL4” in the key-layout map of

page L1. These answer back codes will be issued by the programmable keyboard to

PC whenever the 6 position electronic key is switched to a new position (there will be

a time delay as determined in the configuration of the keyboard programming utility

and is adjustable by “r” and “t” key presses, this time delay is useful to give only the

answer back code of the last position of control key when it is turned across multiple

positions) or when the keyboard receives an “enquiry” code (E7h) from the PC or the

PST system. Here are some examples of sending this “enquiry” code in different

languages:
