Figure 3 – 3 Customer I/O Interface Pin-outs
The customer I/O interface connector contains the lock, main power, RF solid state outputs,
the trigger signals (solid state), and RS422 (
Figure 3 – 3 ).
Tag Lock Output
The transistor-transistor-logic (TTL) lock signal shows the presence of a tag. The lock signal
goes active high when a valid tag is in the RF field of the antenna and may be connected to
an LED for monitoring purposes.
The tag lock relay is referenced to 5Viso and I/O Ground.
Main Power Output
The TTL main power signal goes active high when the ON/OFF switch on the front panel
is switched to on. The main power signal may be connected to an LED for monitoring
purposes.
The main power relay is referenced to 5Viso and I/O Ground.
