Why don't barcode scanners always work?
Actually, barcode scanner aleays work, we always know that barcode
scaners read barcode with red light over a barcode, so you think
the barcode scanner are working, and when the red light turn off,
the barcode scanner was not work.
But barcode scanner always work when red light off, just modules
was set up by sense mode. we often has 3 kinds of scan mode.
1. Trigger Mode
If the Trigger Mode is enabled, driving the TRIG pin on the host
interface connector low activates a
decode session. The session continues until the barcode is decoded
or decode session timeout expires
or the active trigger signal is no longer present. For good decode,
the engine transmits decoded data via communication port. To
activate another session, the Host needs to first negate the
trigger, waits 20ms or longer and then drive the TRIG pin low.
2. Sense Mode
If the Sense Mode is enabled, the engine activates a decode session
every time it detects a change in
ambient illumination. The decode session continues until the
barcode is decoded or the decode session
timeout expires.
Driving the TRIG pin on the host interface connector low can also
activate a decode session. The decode session continues until the
active trigger signal is no longer present or the barcode is
decoded or the decode session timeout expires. The trigger signal
needs to be negated before the engine is able to monitor ambient
illumination again
3. Continuous Mode
This mode enables the engine to scan/capture, decode and transmit
over and over again.
When the engine is operating in Continuous Mode, barcode reading
can be suspended/resumed through
control over the trigger signal. When barcode reading is in
progress, negating the trigger signal after
having maintained it for 30ms or longer will suspend barcode
reading; when barcode reading is
suspended, performing the same control over the trigger signal will
resume barcode reading.
Access Control Solutions Share: Protecting company assets and
employees is a concern every business has regardless of their size.
Security is a greater concern than ever and advances in access
control technology have moved well beyond the traditional lock and
key method. Electronic access control provides improved security
and better management of your facility access by utilizing secure
IDs that can be tracked at every doorway. Control who as access to
your building and never have to change a lock again.
