Offline Read Test Function

Communications tests between the Antenna connected to the Controller and
Tags can be performed without any connections to a host. This function can
be used to check the Antenna mounting location before trial operation.
The function is enabled by turning ON DIP switch pin 3-3 on the Controller
before turning ON the power supply.
