– THE RF EAR
The RF EAR is a very efficient monitoring tool that supplies valuable
information about the communication between the RF MASTER and the
SLAVES of a particular system to which it is tuned.
The RF EAR contains an RF receiver/transmitter, which resembles the RF
MASTER but functions in a totally different way
– it does not transmit anything
but it is continuously open for reception of any transmissions made by the
members of the system. The RF EAR picks up only data transfer using the
communication protocol utilized by Talgil RF systems and only if it is in the
selected frequency. Therefore, the collected information shows the behavior
of the particular system being tested, the information is displayed at a real
time basis on the screen of a mobile PC and it is continuously recorded for
later inspection.
By moving around with the RF EAR and recording the reception quality at the
various RTU locations and at the center, one can identify the weak points of
the system and decide about the solutions.
Usually the receiver/transmitter unit of the RF EAR will be installed on a long
PVC pole that enables raising it high at the places being checked.

HOW TO USE THE RF EAR ?
1. Set the frequency channel of the RF EAR to
the same frequency of the system being
checked.

2. Turn on the power switch of the RF EAR. The unit will start sounding
sequences of short beeps repeated in an interval of the scanning rate.
Each short beep indicates a communication picked up by the unit.
