4.0 Programming the Unit
4.2.5
Laser On Time
Parameter # 0x88
This parameter sets the maximum time decode processing continues
during a scan attempt. It is programmable in 0.1 second increments
from 0.5 to 9.9 seconds.
To set a Laser On Time, scan the bar code below. Next scan two numeric
bar codes in
Section 5.5
on page
95
that correspond to the desired on
time. Single digit numbers must have a leading zero. For example, to set
an on time of 0.5 seconds, scan the bar code below, then scan the “0” and
“5” bar codes. To change the selection or cancel an incorrect entry, scan
the Cancel bar code in
Section 5.5.1

Laser On Time
(Default: 3.0 sec.)
4.2.6
Aim Duration
Parameter # 0xED
When a scanner with an aim mode (see Table 9-10 on page 9-22) is trig-
gered either by a trigger pull, or a START_DECODE command, this pa-
rameter sets the duration the aiming pattern is seen before a a scan attempt
begins. It does not apply to the aim signal or the AIM_ON command. It is
programmable in 0.1 second increments from 0.0 to 9.9 seconds. No aim
pattern is visible when the value is 0.0.
To set an aim duration, scan the bar code below. Next scan two numeric
bar codes beginning on page 8-71 that correspond to the desired aim
duration. Single digit numbers must have a leading zero. For example,
to set an aim duration of 0.5 seconds, scan the bar code below, then scan
the “0” and “5” bar codes. To change the selection or cancel an incorrect
entry, scan the Cancel bar code in
Section 5.5
on page
95
.
4.2.7
Scan Angle
Parameter # 0xBF
This parameter sets the scan angle to narrow, medium or wide.
Aim Duration
(Default: 0.0 sec.)
Narrow Angle (35°)
(0x05)
*Medium Angle (46°)
(0x06)
Wide Angle (53°)
(0x07)
4.2.8
Power Mode
Parameter # 0x80
This parameter determines the power mode of the engine.
In Low Power mode, the scanner enters into a low power consumption
Sleep power state whenever possible (provided all WAKEUP commands
have been released).
In Continuous Power mode, the scan engine remains in the Awake state
after each decode attempt.
The Sleep and Awake commands can be used to change the power state
in either the Low Power mode or the Continuous Power mode.
Continuous Power (0x00)
Low Power (0x01)
