POWER MODE
Power modes are controlled by the power mode parameters and it enables to choose
between "Continuous Power Mode" to "Low Power Mode".
6-1.
Continuous Power Mode
In Continuous Power Mode, this scan engine remains active after each decode attempt. It
enables quicker response to the requests for trigger signal input and so on.
6-2.
Low Power Mode
In Low Power Mode, this scan engine enters into low power consumption Idle state.
To recover from Low Power Mode, it needs to satisfy one of the following conditions:
(1) In case when CTS signal is set to L-level and the data transmission request is sent to
the host system, this scan engine sets RTS signal to H-level and waits for the data to be
transmitted.
If it was recovered from the Low Power Mode by changing CTS signal level, it must
maintain the Idle state for a second after the data transmission.
(2) In case when the trigger signal is set to active, the decoding operation shall be
restarted.
If the trigger mode is set to "Host", decoding operation shall be set to "Pulse".
If the trigger signal is still set to active after a completion of decoding or the decoding
time-out, it shall not go back to the Low Power Mode.
(3) In case when AIM/WAKE signal is set to L-level, this scan engine puts aiming on and
gets into Idle state.
If the input signal is set to "Pulse", it sets back to the Low Power Mode in a second.
If the input signal is set to a level, it maintains Idle state while it is active.
If it satisfies more than 2 of the fore-going conditions, signals input afterward may be ignored.
Please input signals after confirming the recovery with the Power Down signal (see below).
6-3.
Power Down Signal
Power Down signal outputs the level of power mood state of this scan engine.
If in the Low Power state, Power Down signal is set to H-level and if not, it is set to L-level.
