It is possible to change the command used in Serial communications to execute Read.
There are two types of Read execution commands. One includes a Separator Character (delimiter) <>
and the other has no delimiter.

acter (Delimited)
ASCII code for 1
character
(Default:
Space(Hex: 20))
Specifies the command character string used to start a Read. To
execute the command, the trigger character must be delimited in
brackets <>.
This command can only be executed when the Trigger Mode is
set in Read Cycle -
Trigger - Mode to either Serial Data or Serial
Data or External Edge.

(Hex:00))
Specifies the command character string used to start a Read and
the command character used to end a Read.
The Start command character and the End command character
must be different characters. When set it to NULL (Hex:00) it is
disabled.

Cycle -

• If External Edge is selected, the code reader executes Read
with the Start command character. An End command character
is not necessary.
• If External Level or Serial Data and Edge is selected, the Start
trigger character starts a Read cycle and the End command
character ends the Read cycle. Even for a Good Read, the
Read Cycle does not end until the End command is sent.
