Manual No. 25-ULPNMU01-01 LPN1736 Omni-Directional Laser Scanner
Sleep Mode
The default setting of the LPN 1736 the laser diode and motor are “on” whenever power
is applied to the scanner.
The scanner can be programmed to turn off the laser and the motor after a period of time
with no scanning activity (no bar code presented for scanning).
This will place the scanner into a waiting or “Sleep Mode”, not into an Off mode. In this
mode, the scanner is resting, waiting for a bar code to be presented for scanning. When a
new bar code is placed into the scanning area, the scanner will sense its presence and
wake up the scanner from its sleep mode to read the bar code.
The length of time before the scanner goes into the sleep mode can be programmed. It
can be set for a period of between 10 seconds to 1 hour.
The sequence to program the scanner so that it enters a Sleep Mode is shown below. You
need to scan the required programming bar codes in the sequence shown. These
programming bar codes are on the following pages.
1. Start / Stop Programming Mode (ZZ)
2. Enable Trigger (S8)
3. Set Read Time to Indefinite (YM)
4. Turn on Auto Trigger (+I)
5. Disable Motor when Idle (4Z)
6. Set Auto Shut-off Time ([BBB)
7. Enter Desired Shut-off Time (in seconds, e.g, 1 hours = 3600) using Direct
Input Number bar codes
8. Start / Stop Programming Mode
For an RS232 interface, you can also program the scanning for sleep mode by
transmitting the following command codes in the sequence shown
<ESC> <S8> <CR>
<ESC> <YM> <CR>
<ESC> <+I> <CR>
<ESC> <4Z> <CR>
<ESC> <[BBB> <Q3><Q6> <Q0> <Q0> <Q0> <CR>
<ESC> <Z2> <CR>
