POWER SAVE
4.4.1
Sleep State
This mode allows the µ P in the reader to enter a "Sleep" state for minimum power
consumption. This command is only valid when On-Line is selected.
Before entering Sleep mode, the following are verified:
•
no commands coming from Host
•
no data being transmitted to Host
•
Enter Sleep Timeout ended
To exit Sleep mode press the trigger.
Enabling the Sleep state implements Standby mode for CCD devices.
4.4.2
Enter Sleep Timeout
For readers that have the Sleep state enabled, this timeout determines when the
reader will enter this state.
4.4.3
Standby
If this command is enabled, part of the CCD circuitry shuts down (Standby), in order
to optimize low power consumption when not reading. When the trigger is pressed
this circuitry powers up. This mode causes a minor delay of about 100 ms before the
reader is ready.

READING PARAMETERS
4.5.1
Operating Modes
This group of parameters allows setting different reading modes:
•
ON-LINE: the TC1100 reader is connected to an external Presence Sensor
using EXT TRIG+ and EXT TRIG- inputs. During the active phase of the
presence sensor, the TC1100 tries to acquire and correctly decode the code. If
the operation is successful, the barcode characters are transmitted on the serial
interface in the format defined by the current configuration. Otherwise a No
Read message is sent: it is fixed as the CAN symbol;
