Testing
Before deploying a VR2Tx, it is wise to test it with a tag to verify that it is
operating properly. This test also creates a VRL file containing all the
configuration information for this receiver – handy to keep as a record of
the receiver’s configuration.
Tests can, and should, be done in both air and water.
2.4.1
In-Air Test
The VR2Tx can detect coded pingers in air, but at a much reduced range compared to their range capabilities
in water. Perform air tests away from electrical noise sources such as motors, PC screens, or fluorescent
lights.
To perform an in-air test, follow the steps below.
1.
Use Bluetooth to setup receiver for test:
a.
Activate the
Bluetooth
feature on the VR2Tx (section 3.3).
b.
Establish communication between the VR2Tx and VUE software (section 3.4).
c.
Select the VR2Tx’s transmit mode (section 3.5).
d.
Begin a Study. Section 3.8.1 has the details of how to begin a study, also known as
initializing the receiver.
e.
Disconnect the wireless communication with the VR2Tx (click the red box with the “X” in
the receiver ribbon).
2.
Activate at least one 69 kHz tag and place it less than 30 cm (12”) away
from the hydrophone so the side of the tag is facing the side of the
hydrophone.
3.
Wait while the VR2Tx records the tag(s) near it. You can watch the red
flash patterns as the tag is detected and the data is stored in memory.
Each faint red flash of the Status Light is a received ping and a long,
bright red flash is a stored detection. If the flash pattern is different,
compare it to the Status Light Meanings chart (section 6.2).
4.
Communicate using the transponding hydrophone and VR100-200
(details about using the VR100-200 are found in the VR100 related user
manuals).
a.
Connect the transponding hydrophone to the
hydrophone connector on the VR100-200
b.
Place the caged end of the hydrophone within 15 cm
(6”) of the hydrophone on the VR2Tx.
c.
Turn on the VR100-200.
d.
Select “Transpond” in the main screen.
e.
Select “Scan” and wait for the VR2Tx’s serial number
to appear on the screen. You must wait until the
count-down is finished before you can proceed.
f.
Select the VR2Tx.
Perform air tests away from
electrical noise sources such
as motors, PC screens, or
fluorescent lights.
