TEKBOX TBSL1 TELEMETRY UNIT

TBSL1

 

The Tekbox TBSL1 represents a new milestone in telemetry unit design. Rather than being locked to a particular communications technology,  the TBSL1 puts the modem components on a separate daughter board. Customers can purchase a bare TBSL1 and then fit the module for the required communications method: LoRa WAN, 3G, 4G etc.. The RTU will automatically detect which type of modem is fitted and adjust accordingly.

The TBSL1 is built into a powder coated aluminium case. A breather vent is fitted to the top of the case to prevent moisture build-up. Waterproof connectors are used for the solar panel (5pin) and sensor (7pin( inputs. The antenna mounts to a TNC connector on top of the case. A bracket is fitted to the rear of the case to allow the unit to be fixed to a post or mast..

 

Inputs and Outputs

 

The primary purpose for the TBSL1 is as an SDI-12 RTU. But for added flexibility it also carries two analogue inputs and two pulse counter inputs (for connection to rain gauges and flow meters - please note that only one of each is supported in the current firmware). The relay output on the TBSL1 can be turned on in response to an alarm condition.

 

Rechargeable Battery

 

Power for the TBSL1 comes from an 18650 size rechargeable battery. Depending on sensor load and transmission interval, the unit may be charged via either a 12V 2watt or 12V 5 watt solar panel
 

 

Configuration

 

The TBSL1 is configured using the Tekbox TBSL1 GUI. This program allows you to nominate what sensors are attached and the interval at which they will be read. You can also specify sensor warm up times.
The GUI gives access to all of the communications parameters. In a 3G/4G environment, this includes details such as the server type and login credentials. ON a LoRa WAN unit it includes the network join type, encryption keys and transmission interval.
With the GUI you can send commands to the attached SDI-12 sensors, for configuration and testing and can also send commands to the modem .

 

Alarms

 

Alarms may be set on the value of any of the internal or external sensor channel, or on the value of a calculated channel . When an alarm is triggered the units may send an SMS to one or more recipients (3G/4G units) or send a message via the server (LoRa WAN units) . Further alarms may be generated from  within n the server  software once the data reaches it

 

TBSL1-LO

 

The TBSL1-LO is the designation given to the unit when it is fitted with a LoRa WAN modem module. This module utilises a LoRa WAN modem manufactured by Rising HF..
 The TBSL1-LO is normally supplied with a 900 MHz radio module allowing it to be used on the Australian, US and Asian channel plans: AS915, US915 and AS923.  An 868 MHz module for use in Europe may also be supplied on request.
For more details, see the TBSL1-LO brochure.

 

TBSL1-3G

 

The TBSL1-3G is the designation for the unit when fitted with a 3G mobile phone (cellular) modem. Modem boards can be supplied to suit the frequencies in use in most countries. Watch this site for more details on the release of the TBSL1-3G and TBSL1-4G

 

TBSL1-4G

 

Whilst 3G has been the main stay of cellular communications for some time, many countries are now moving their networks to 4G. This allows for faster communication and more flexibility. An LTE-M1 modem will be added in the  near future  to provide an option for those who wish to build their LP WAN (low power wide area networks) on the back of the carrier’s investment.
