Trigger Input

There is one trigger input for each Antenna (two total) which can be used to tell the ID Controller when
to start Tag processing. Once the ID Controller has received a command, it will wait for the rising edge
of the trigger input and then communicate with the Tag.

If auto commands are used, the ID Controller will wait from the rising edge of the Trigger input for a Tag
to enter the communications area. This means that read/write processing will not start after a com-
mand is received until the rising edge of the trigger input, even if a Tag approaches.
