If your Tube is receiving poor signal or frequently misses transmissions, you can check
the following to help determine the cause.
∙ The well casing may prevent the Tube from sending or receiving transmissions.
Consider using an external antenna (PN 0062240) that can be mounted on the top of
the well to prevent casing interference.
∙ Check the cellular provider's coverage area map. Your deployment area may be in a
non-coverage area.
∙ Check the area surrounding your equipment. Objects like trees, electrical wires, and
cement walls can affect cell reception. Consider moving the Tube to a different area to
test reception.
∙ If your system cannot be moved, consider using a different type of antenna that can be
mounted away from potential interference.
Troubleshooting
SIM Card
Tube 300 units require a SIM (subscriber identity module) card for communication over
the wireless network.
If you are managing your data plan through In-Situ Inc., a SIM card is installed in the
equipment prior to shipment.
If you are managing a data plan through a third party, you must obtain a SIM card from
their service provider and install it yourself. Consider if your application requires a static
IP address when purchasing the SIM card.
Once a SIM card is obtained, install it in the Tube as shown below.
The SIM card slot is located between the two circuit boards, next to the circular cutout
closest to the battery terminal.
