3.2.3 Example 3
To synchronize two readers see the following instructions.
On Reader 1:
DECLARE cursor_one CURSOR FOR SELECT id FROM tag_id WHERE protocol_id='EPC1' SET
time_out=300;
SET auto_time cursor_one = '2005-02-01T13:00:00Z', repeat=1000;
The first reader will start reading for no less than 300 ms at just 13 o’clock, and it will repeat the command
1000ms.
On Reader 2:
DECLARE cursor_two CURSOR FOR SELECT id FROM tag_id WHERE protocol_id='GEN2' AND
read_count>1 SET time_out=300;
SET auto_time cursor_two = '2005-02-01T13:00:00.5Z', repeat = 1000;
The second reader will start reading for no less than 300ms starting at time 0.5 second after 13 o’clock, and it
will repeat the command every 1000ms.
The effect will be that each reader will have a almost 50% duty cycle with each one only active when the other
one is off.
