23. Setting the Trigger Function

Computer Command
(Z7)
The trigger function is disabled in the default setting. This means that the red scanning light is "ON"
continuously and the scanner is always ready to read. For some applications, you may wish to activate the
scanner only at a specific time. This can be done by enabling the Trigger function. Once in the "Trigger
Enabled" mode, the red scanning light is OFF until the trigger is activated or "pulled." Either a hardware trigger
or a software trigger pulse may be used to activate the scanner.
The hardware trigger is actuated by pulling Pin #1 (on the standard DB25 female connector) LOW. The
software trigger is actuated by downloading and <ESC> Z <CR> computer command from the host. (See
Scanner Timeout to establish the length of time the scanning light remains ON after the trigger is activated).
