ATS Pinger Dish IV User Guide
R-11-20A

Pros: This method doesn’t require that the tag be held in
position.
Cons: It uses a small amount of water and requires that 3G or 4G tags to be manually positioned
so that their transducers are perpendicular to the transducer of the Pinger Dish.

Using the Pinger Dish to Activate/Deactivate Tags
To turn the Pinger Dish on, press the small
Restart
button on the right side of the top of the unit
(just below the LCD display). When the
Restart
button is pushed, a short “Beep” can be heard
from the speaker.
The Pinger Dish’s title screen will be displayed along with the
two firmware
versions (one for the Pinger Dish processor and a separate one for the DSP decoding processor).
The Pinger Dish looks for a JSATS
tag’s signal to decode
after displaying the message
“
Waiting
for JSATS Tag P
ulses”.
If approximately two minutes have elapsed without a tag being detected
(or a computer command being sent), the system turns off automatically. Pushing the
Restart
button again turns the Pinger Dish back on. It is unlikely that the Pinger Dish will
unintentionally turn off during normal operation since the time between transmitter
’s
pulses
should usually be less than the automatic shut-off time of two minutes.
To activate or deactivate a tag, place it on the surface of the cup. Please refer to section 3 on the
various options.
After the tag is positioned on the top of the cup, use the three-position toggle switch (directly
below the cup with the tag) to activate or deactivate the tag. Moving the switch to the left
activates the tag (the green LED will flash) and moving the switch to the right deactivates the tag
(the red LED with flash). The switch is a monetary switch and does not need to be held in the
activate position or deactivate position for a very long period of time. Additionally, holding the
switch in either position for an extended period of time will not extend the time that the
‘activate’ or ‘deactivate commands are sent
to the tag (this fixed amount of time should be all
that is necessary, for a properly functioning ATS JSATS tag, to detect the activate/deactivate
commands coming from the Pinger Dish).
A tag in the Pinger Dish is confirmed as being active by
an audible “Beep”
from the Pinger Dish
whenever the activated tag transmits a JSATS code. The JSATS tag
’s
pulse specific values are
then displayed
on the Pinger Dish’s LCD display
:
1)
Tag code value (4 digit hexadecimal number: $12DA for example)
2)
CRC value (cyclic redundancy check; used for error detection)
3)
PRI Measured (pulse rate interval, in seconds with 1000
th
of a second precision)
4)
Estimated tag frequency (in kHz)
