3.5 Basic Commands
3.5.1 Trigger Command
You can start and stop reading by sending commands. When the read cycle timeout is set to 0
seconds (Y0 command), the read time with the Z command is set to ‘Indefinitely’ and reading
continues until a Y command is received. For timeout limited reading, use the Yx commands.
For more information, see “Read Timing” on page 48.
