Microwave time-sharing
The microwave antenna of the TRANSIT Ultimate is continuously on. This will ensure the fastest identification.
However it may cause interference on other 2.45GHz equipment.
Enable the microwave time-share mode to only use the selected frequency periodically (the reader automatically
switches on and off). During the periods that the TRANSIT reader is off, other equipment can use the same frequency
undisturbed.
The reader will be on for 300 milliseconds, which is long enough for a reliable identification of a tag. The off-time is
between 0.5 and 5 seconds. This is configurable with the TX-PER potentiometer.
