Product Reference Guide 253
Serial Start Character (or String): Specifies the string message to be sent over the host interface
to activate the reading phase
Serial Stop Character (or String): Specifies the string message to be sent over the host interface
to stop the reading phase.
The Serial Start/Stop Characters must be different and must not contain
reserved characters (see
Appendix E, Reserved Characters).
Phase Off Event: Specifies whether the reading phase is closed on a timeout or phase off event.
The following selections are available:
• Trigger Stop: the reading phase ends when the seri
al stop character (or string) is received.
Timeout is disabled.
• Timeout: the reading phase ends when the timeout is expir
e
d. Serial stop character (or
string) is ignored.
• Trigger Stop - Timeout: the reading phase ends when the first event occured.
Timeout: Specifies the maximum duration for the reading phase. Selections: from 40 to 5100
ms in 20 ms increments.
Automatic
In Automatic mode, the scanner is continuously scanning. When a label enters the reading zone
and is decoded, no more decodes and reading phases are allowed until the label has left the
reading area. In order to guarantee identification of the code in the reading zone, a threshold
specifies the number of scans after the successful decode that the scanner will wait before
rearming the reading phase. The transmission of the decoded label depends on the
configuration of the Transmission Mode parameter.
Automatic mode configurations:
Automatic Threshold: Specifies the number of “empty” scans allowed after decoding a label,
before the scanner switches back to a new reading phase.
Automatic/Trigger Object Sense
Automatic/TOS mode is the same as Automatic mode, but with the lighting system OFF. As an
object or barcode enters the reading area, the light is turned ON. The light will return OFF as
the reading phase is closed (see Automatic Mode above).
While in Trigger Object Sense Mode the green spot stays on while in
stand watch state.
Test Mode
Test Mode reports information about the reading performance of the reader, and the code is
continuosly read. After 100 scans, the following information is transmitted to the Host:
•The code content
• Percentage of good reads. If the good read
per
centage is 0, no transmission occurs.
The information can be displayed on the Host PC by running a terminal emulator program
such as HyperTerminal. The outp
ut data format is fixed.
