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 9-pin mini-DIN 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.)
