IV.1 Setting Up the Parameters of the RT961B2S-Mk2
The RT961B2S-Mk2 unit is fully field-programmable. This is achieved by using the MMI
configuration software.
Refer to section VI for the RT961B2S-Mk2 configuration with the MMI software.
IV.2 Testing the RT961B2S-Mk2
A built-in test with the RT961B2S-Mk2 is available. The unit transmits an acoustic pulse
once the unit is switched ON and power-up steps are safely completed.
After a long period of storage, the internal storage capacitor associated to the acoustic
power amplifier can be fully discharged and the acoustic power level transmitted may be
very low and inaudible. If it is the case, switch OFF the unit, wait for 3 s and repeat the
switch ON operation.
End of
Storage
Responder mode can be tested by switching on the unit and sending a 10 ms wide and
positive 5 V pulse on the responder input. The RT961B2S-Mk2 transmits then a CRF
acoustic pulse.
Responder
Mode Test
Test the transponder mode by interrogating the unit at one of the interrogation
frequencies. One can use a frequency generator to send an interrogation signal (acoustic
or electrical with a wire loop around the transducer using capacitance coupling).
Transponder
Mode Test
RT961B2S-Mk2 should transmit an acoustic pulse if the frequency of the interrogation
pulse matches the receiving channel set for the RT961B2S-Mk2 unit.
Test also the emergency power supply mode. If external power supply is switched OFF,
the RT961B2S-Mk2 should revert to the internal battery supply and continue to reply
either in responder mode or transponder mode.
Emergency
Power Supply
It is possible to test several functions of the RT961B2S-Mk2 with the MMI software. Refer
to section 0.
