Air Acoustic Testing 

CAUTION!

 

Do not exceed -3 PSIG while purging the housing, as an excess vacuum 
can damage the batteries. 

Always perform an air acoustic test of the commands and interrogate the instrument after assembling to 
assure proper working order. Every time the instrument is powered up, repeat the air acoustic test to 
assure proper engagement of the On/Off plug. Place the  deck box transducer  within 1 meter of  the 
underwater unit transducer when sending commands. The position of the transducers relative to one 
another may need to be adjusted to allow commands to get through in air. Ranges will not be accurate in 
air; these systems are designed to operate in water. The speed of sound in air can cause errors in 
command decoding and prevents accurate ranging however the systems can be tested in air. Test all 
functions of the system by sending each command and verifying that the state changed according to the 
command including status reply. 

 

Setup 

The specific acoustic impedance of air is quite different from that of seawater, which renders the 
Transducer a far less efficient receiver when out of water. For this reason, it is necessary to place the 
source (Deck Unit Transducer) within a meter or two of the 8242XS Transducer, with no obstructions to 
the acoustic path. Depending on the environment, some experimentation may be necessary to find a 
suitable location.

 

 

Tests 

For the following tests, it will be necessary to have the proper six digit commands unique to the unit being 
tested. If it appears that commands are not getting through, verify that the serial number of the unit being 
tested matches that on the sheet of command codes. 

Using a deck unit, ascertain whether the 8242XS is enabled or disabled by interrogating it if the unit has 
just been powered up it will be enabled. Unless otherwise specified, the 8242XS will be shipped from 
EdgeTech with the interrogate frequency tuned to 11 kHz and the reply frequency set to 12 kHz.
