The reject gate is on OP2 and pulses high to reject the product. Products
take 10 seconds to travel from the sensor to the reject gate, and take 1
second to move past the reject gate. The configuration details for this are
shown below:

10 seconds after a trigger, OP2 is set to pulse for 1 second to reject a
product.
The camera trigger has the 'Send trigger message' flag set. So that when
the product is detected, a message is send to the image processing
software. The image processing software must use the GT command to
receive these messages.
The image procesing software has to send a pass/fail message before the
reject gate is reached by the product. As well as 'Resync mode', the
'default to pulse' flag is set. This means that if the image processing
software does not send a pass/fail message, OP2 is pulsed anyway. The
timing diagram for this is shown below:
In this example, three product triggers were received. The camera was
triggered using OP1.
An Ethernet message with tag number 10 was sent to the host computer
when the first trigger was received, but a reply was not received, so the
product was rejected for fail-safe operation.
