62. Note that it is recommended that the battery is charged and THEN the device schedule is set
rather than the other way round.
Charging the basestation
63. The basestation can be recharged via the PC or solar. If recharging via the PC the progress of
this operation can be observed using the battery monitor in the top right of the software.
Deploying device and basestation
64. During the first ten GPS attempts the LED on the device (if visible) will flash to indicate GPS
success or failure. If the device obtains sufficient satellites to obtain a location then the LED
will flash five times, if not it will flash twice.
65. After the first GPS attempt, the tag will attempt to offload its first GPS data point to the
basestation so that the operation of the system can be verified at the earliest possible
opportunity during the deployment. It is recommended that the basestation is enabled at this
time and it is within the coverage area of the tag so that this verification can take place.
66. When the basestation is enabled, it will listen for transmissions from the tags that have been
configured to transmit to that basestation. Each time the basestation begins a new listening
window its red LED will light briefly. The duration of each listening windows is fixed, but the
frequency of these listening windows is governed by the basestation’s battery voltage.
Whenever possible, when the basestation is active, it should be positioned so that the solar
cells are able to recharge the battery.
67. When the basestation receives a transmission from a tag and begins a data download, the
“UHF Data” LED on the front of the basestation, which is yellow in colour, will light. This yellow
LED will remain lit whilst the download is taking place. If the download completes successfully,
the yellow LED will go off, followed swiftly by two fast flashes of the red LED and third flash
after a brief pause.
68. If a basestation is to be left enabled in the field in order to regularly download data, then it is
essential to adhere to the following instructions, in order to maximise your chances of
downloading data:
• Ensure the basestation is placed within a reasonable range of where you expect your
target animal to be. In perfectly clear line of site, it is possible for downloads to occur
up to 2km away, but, for normal conditions, we recommend no more than 200m.
• Elevating the basestation will increase the range in which it is able to communicate
with tags. We would recommend you do this using a non-metallic post.
• Orientating the solar panel on the basestation to the direction in which it will receive
the most sun is important for keeping the battery charged and increasing the length
of a given deployment.
• Try to ensure that the basestation is placed in a relatively clear location, away from
trees buildings, and other potential obstructions.
• Do NOT deploy a basestation near masts, pylons, or similar electrical installations.
