WLS-RS300 is a 2.4GHz wireless receiver, it is mainly installed in fixed position to receive the 2.4GHz wireless location data of WLS-T01, WLS-T02 and WLS-T11 broadcast. In the other hand, WLS-RS300 is also a wireless converter (called Router) from 2.4GHz to 400MHz. it can effectively use 400MHz high transmittance characteristics to extend the wireless transmission distance, and don’t need add wire between the communication paths. The WLS software in the PC can use transparent function of RFU-400 to poll the wireless location data of WLS-RS300, and then calculate the relative position by the algorithm. The user can simply use the DIP switch and rotation switch to configure the parameter, and don’t need to add wire between the communication paths. It very suitable for use in item tracking, personnel movements, factory regional management and other applications.
