The TRANSIT Ultimate reader operates in the 2.45GHz ISM frequency band.
When two or more readers are within a range of 15 meters (50 feet), these readers should be set on a different
operating frequency.
It may also be required to select a different frequency to avoid disturbance between the TRANSIT Ultimate and other
2.45GHz equipment, such as Wi-Fi access points.
Please also read chapter 6.6 when experiencing interference.
The frequency channel is selected on the transceiver board which is located in the front cover of the reader. Select the
frequency channel using a display & push-buttons (see chapter 6.4.1) or using dip-switches (see chapter 6.4.2).
The TAB board operates at 433 MHz. It uses 2 fixed frequency channels. This cannot be changed.
