GENERAL
1.1 DESCRIPTION
The LT1 is a battery powered compact data collection platform with a built-in telemetry module,
either cellular or satellite (GOES/EUMETSAT or Iridium).
IMPORTANT:
• The LT1 MUST be mounted in an IP66 weather-proof enclosure that is fitted
with a 35mm x 7.5mm DIN rail.1
• The LT1 must be used in conjunction with FTS360, a secure web-based software
platform and the associated FTS360 Config App2, accessible from a computer
browser or smart device. Details are in Chapter 2.
Most aspects of the installation and operation of all models are the same. This manual will use the
term LT1 when describing all common aspects. Specific models will be identified for information
unique to their operation. Refer to Appendix C for specifications of each model.
The LT1 has a data terminal block which accommodates SDI-12 and NMEA sensors and a counter
specific to a tipping bucket rain gauge. It has a spring clip for mounting the unit on a
35mm x 7.5mm DIN rail. The serial number for the LT1 is found on a sticker under the flexible port
access cover (see Figure 1-2).
1.2 LT1 VERSIONS (LT1-CELL/LT1-GOES)
Each model of LT1-Cell and LT1-GOES have two versions: the original and an updated version (V2).
V2 units have hardware upgrades which offer additional features over the original version. These
upgrades are:
•It can support four SDI-12 sensors (original version supports two)
•It has a larger memory capacity to support more sensor parameters and redundant
message configuration
The indicator V2 will follow the model number on the product label (eg: LT1-GOES V2). Additionally,
the firmware will begin with the number 2 (eg: 2.0.6). The firmware version the LT1 is running is
displayed on the “Edit Station” screen in FTS360and in the FTS360 Config App at the bottom of the
dashboard, when connected to the LT1.
1The LT1 is designed to operate in a dry, protected environment. Exposure to rain greater than 1mm per minute, spraying or
splashing water may cause the unit to fail.
2Details of FTS360 and the FTS360 config App can be found in 700-FTS360-Man( FTS360 and FTS360 Config App User Manual)

1.4.1 SDI-12 VERSION 1.3
The LT1 follows SDI-12 version 1.3 protocols with the exception of cyclic redundancy check (CRC)
commands and continuous measurement commands which it does not support.
1.4.2 SD CARD AND MICRO-B USB PORTS
The SD card and Micro-B USB ports are accessed by opening the rubberized access cover. The SD
card stores data locally (details in section 2.3.2). The USB port is used for connecting to an LT1
station with a computer using the FTS360 Config App for Windows. To close, ensure the cover is
firmly seated by running your thumbs along the side of the LT1 and overlapping the edge of the
access cover.
NOTE: Do not apply direct, localized pressure3to the edge of the cover immediately
over the SD card as this may disengage the SD card.
Figure 1-2: SD card and Micro-B USB port access
The LT1 is shipped with an FTS tested and approved industrial grade SD card inserted in the SD card
port. Detailed information on SD cards and their use can be found in section 1.6.
IMPORTANT!
Only FTS supplied SD cards should be used with the LT1 for logging.
SD cards should only be removed as per instructions in Section 1.6.1
1.4.3 SIM CARD PORT – LT1-CELL
Only LT1-CELL models require a SIM card to operate. The SIM card port is accessed through the FTS
panel located on the side of the device (see Figure 1-3). To open the access panel, insert a small
screwdriver into the slot and gently pry the panel open.
NOTE: Only open the access panel in a protected, dry environment.
Any moisture entering the electronics compartment can cause the
microprocessor to fail.

The SIM card holder will be firmly seated in the locked position. To unlock it, gently slide the black
holder towards the SIM card holder’s hinge. Once it is unlocked, the SIM card holder will spring up
slightly and then it can be swung to its fully open position, from which the SIM card can be
removed/inserted.
When returning the SIM card holder to its seated position, apply slight pressure and slide the back of
the SIM card holder to the locked position.
IMPORTANT! When inserting or removing the SIM card, care must be given to
ensure the SIM card is not bent or damaged in any way as this may result in
transmission failure.

1.5 TELEMETRY AND NETWORK COMMUNICATION
The LT1 can be ordered with either cellular, GOES/Meteosat, or Iridium telemetry. Local
communication with an LT1 is performed using the built-in Bluetooth module and FTS360 Config
App available on iOS and Android devices.
1.5.1 LT1-CELL
The LT1-CELL uses Message Queue Telemetry Transport (MQTT) messaging protocol, a standard
commonly used for Internet of Things (IoT) applications, for remote transmissions. It transmits
sensor and station data and receives commands such as firmware updates over the internet.
Station and data management is handled by FTS360, a secure web-based software platform.
Data from the LT1-CELL is stored locally, and then securely sent to FTS360 which provides real-time,
high-speed access to the LT1-CELL’s data. FTS360 can be accessed from the browser on a computer
or on a smart device.
1.5.2 LT1-GOES
The built-in G6 transmitter of the LT1-GOES is certified by NOAA to operate on the GOES satellite
network, and by EUMETSAT for the Meteosat network. It transmits station and sensor data in
GOES/Meteosat industry standardized formats.
