3Safety and Product Care
This device has been designed in accordance with industrial standards, manufactured with high
quality materials, and thoroughly tested. Nevertheless, its use may constitute a risk to persons or
cause material damage.
The following safety instructions must be followed to ensure the safety of users and of the
device.

LT910-WW User Manual - Telic AG
Pg 13
NOTICE
If these instructions are ignored, Telic AG will not assume responsibility for any damages
that are incurred. Telic AG may refuse warranty claims where evidence of product misuse is
found.
Please read the information in this section and the information in Section 6 Installation of the
modem before starting your integration work!
3.1 Safety instructions
PLEASE READ THESE SAFETY INSTRUCTIONS AND KEEP A COPY OF THEM.
The LT910-WW Terminal contains highly integrated components which can be damaged by
electrostatic discharge.
Therefore, only touch the LT910-WW Terminal on the housing or connectors and avoid
touching the components on the board.
Always ensure that the use of the modem is permitted. The modem may present a
hazard if used in the proximity of personal medical electronic devices. As a rule, the
modem must not be used in hospitals, airports or planes.
Never use the modem at a gas station, refueling point, blasting area or in any other
environment where explosives may be present.
Operating the modem close to other electronic devices, such as antennas, television sets,
and radios may cause electromagnetic interference.
This product is intended to be used with the antenna or other radiating element at least
20 cm away from any part of the human body. In applications where this rule cannot be
applied, the application designer is responsible for providing the SAR measurement test
report and declaration.
You are responsible for observing your country's safety standards, and where applicable,
the relevant wiring rules.
Warning
When using products which are exposed to electric voltage the valid regulations
must be observed.
Always make sure that the device is disconnected from the power supply before opening it.
You should only use tools on components, modules or devices if they are disconnected from the
power supply and the electric charge, which may still be stored in some components inside the
device, has been discharged. All cables and wires which are energized and connected to the device,
the module or components must be checked regularly for any damage of the isolation shield or

LT910-WW User Manual - Telic AG
Pg 14
fractures of the cables. If the supply cables are visibly damaged the device must be taken out of
commission immediately.
When using components or modules, the specification given in the corresponding description of
these components must strictly be observed. The device shall be operated only by appropriately
qualified personnel.
This device shall only be used for its intended purpose.
Please note that the quality and availibility of the WWAN network is depending on the network
coverage in the area of deployment and the performance of the network provider. We are not
responsible for any wireless connection errors or data loss caused by these external factors.
General precautions
The LT910-WW Terminal is designed for indoor use only. To use it in an outdoor application it
must be integrated into a weatherproof enclosure. Do not exceed the environmental and
electrical limits as specified in section “2.4 Product Features and Technical Data”.
Avoid exposing the modem to open flames or to extreme hot or cold temperatures.
Never try to dismantle the modem yourself. There are no components inside the modem
that can be serviced by the user. If you attempt to dismantle the modem, you will
invalidate the warranty.
The LT910-WW Terminal must not be installed or located where the surface temperature
of the plastics case may exceed 80°C.
All cables connected to the LT910-WW Terminal must be secured or clamped,
immediately adjacent to the modem's connectors, to provide strain relief and to avoid
transmitting excessive vibration to the modem in the installation.
Ensure the cables, supplying power, and input cable to the LT910-WW Terminal do not
exceed 3 meters.
To protect power supply cables and meet the fire safety requirements when the unit is
powered from a battery or a high current supply, connect a fast 2A/32V fuse in line with
the positive supply.
Do not connect any incompatible components or products to the LT910-WW Terminal.
3.2 SIM card precautions
Before handling the SIM card in your application, ensure that you are not charged with static
electricity. Use proper precautions to avoid electrostatic discharges.
When the SIM card hatch is opened, the SIM card connectors lies exposed under the SIM card
holder.
Caution! Do not touch these connectors! If you do, you may release an electrical
discharge that could damage the modem or the SIM card.

LT910-WW User Manual - Telic AG
Pg 15
When designing your application, the SIM card’s accessibility should be considered. We always
recommend that you have the SIM card protected by a PIN code. This will ensure that the SIM
card cannot be used by an unauthorized person.
3.3 Antenna precautions
Consider the risk of lightning in case the antenna is to be mounted outside. Follow the
instructions provided by the antenna manufacturer.
NOTICE
Please note that this LTE device is designed for use with one single antenna only. It does not
support antenna diversity.
Never connect more than one modem to a single antenna. The modem can be damaged
by radio frequency energy from the transmitter of another modem.
Like any mobile station, the antenna of the modem emits radio frequency energy. To
avoid EMI (electromagnetic interference), you must determine whether the application
itself, or equipment in the application’s proximity, needs further protection against radio
emission and the disturbances it might cause. Protection is secured either by shielding
the surrounding electronics or by moving the antenna away from the electronics and the
external signals cable.
The modem and antenna may be damaged if it encounters ground potentials other than
the one in your application.
3.4 Storage Conditions
It is recommended to store the unit within a temperature range from +15°C to +35°C and an
average annual relative humidity of max. 60% without condensation.

LT910-WW User Manual - Telic AG
Pg 16
4Electrical Description
The modem uses the following connectors:
RJ11 6 way (power)
Mini USB (for data)
SIM card reader
FME male coaxial jack (antenna connector)
D-SUB9 female, 9 pins (RS232 serial port)
4.1 Power Connector
An RJ11 six-way connector, as shown and described below, serves as a means of supplying and
controlling DC power to the modem. The use of an external power supply is necessary as the USB
port is not intended to be used as power source.
The supply voltage VCC required by the modem is 7V - 32V DC. Please note that applying the
supply voltage does not switch the modem on. To do so an additional active high control signal,
TO_IN, must be applied for > 1 second.
Please see chapter 5.1 Switch ON the modem for further important details about TO_IN and
power supply requirements, especially if TO_IN is applied in parallel to VCC.
VCC and GND are reverse polarity and overvoltage protected if the antenna interface
and the user’s application are not used or connected to separate grounds. Excessive
reverse voltage or overvoltage can destroy the device.

The modem supports a standard RS232 serial interface via its 9 pin D-sub connector, shown
below. In line with serial communication terminology the Terminal should be considered as the
data circuit terminating equipment (DCE) and the external application or computer as the data

Figure 5 shows gives an overview about the pin assignment of the mini USB connector from the
standard LT910-WW Terminal. The pin assignment of the two versions is the same.
The modem supports a standard USB 2.0 full speed slave interface to receive AT-commands as
well as data transmissions.
Drivers for Windows Desktop and instructions for Linux are available for download from the Telic
AG website (for registered users only).
