NT910G User Manual - Telic AG
Pg 13
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 fractures of the cables. If the
supply cables are visibly damaged the device must be taken out of operation immediately until the
faulty cable has been replaced.

Pg 14
3.4 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 lie 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.
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.
3.5 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 either come into contact with ground potentials
other than the one in your application. Beware, ground potential is not always what it appears
to be.
3.6 Storage Conditions
The following environmental limits must be maintained in order to safely store the terminal and ensure
that it remains functional until a maximum of 12 months:
▪Storage temperature: from 5°C to 35°C
▪Humidity: <75% relative humidity.

NT910G User Manual - Telic AG

4Electrical Description
The modem uses the following standard connectors:
▪RJ11 6-way (power + 1 analogue input + 1 optional output)
▪Mini USB (for data) –Also the power connector for the USB powered variant (optional)
▪SIM card reader
▪FME male coaxial jack (antenna connector)
▪Sub-D female socket, 9 pin (RS232 serial port)
4.1 Power Connector
An RJ11 6-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 5V - 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 over-voltage protected as long as the antenna
interface and the user’s application are not used or connected to separate grounds.

5Operation
5.1 Switch ON the modem
NOTICE
To ensure correct operation of the Terminal, please ensure that a SIM Card has been inserted
into the terminal prior to switching it on.
Do not insert a SIM card into the device while it is switched on. If you find out that the device is
switched on but missing a SIM card, first switch off the modem and then insert the SIM card.
Note that the device does not have a SIM card detect feature.
There are two ways to switch on the modem, once power is applied:
▪assert TO_IN to high level for > 5s
▪activate the RS232 control line DTR for >0.2s

NT910G User Manual - Telic AG
Pg 19
The modem is fully operational after 8 seconds. Logging onto a network may take longer than this and
is outside the control of the modem. The modem can be configured to start up at the time power is
applied by permanently tying power connector signals TO_IN (pin 4) and VCC (pin 1) together.
DTR must be cycled from low to high.
The TO_IN signal requires a positive “edge” (a sharp” signal transition from low to high) to
turn the modem on. This transition should be a rising signal from 0V (GND) to VCC, or at least
a large fraction of that voltage range, and must be applied at the same time as VCC or after it.
Very slow transitions (significantly slower than many milliseconds) or very small transitions
(e.g. only few volts instead of 0V to VCC) will not turn on the module (since they are not
considered to be a “positive edge”).
Although this will not be an issue in almost all typical applications of the modem, there are a few cases
in which the modem might not recognize the power up signal. This is no failure of the modem itself,
the same would apply to almost any electronic device that provides a separate “power on” or “reset”
signal.
Possible cases are the following:
▪Large capacitors in your power supply which will lead to slow leading and falling edges (issue
does not apply with modern stabilized switching regulator power-adaptors) AND TO_IN tied in
parallel to VCC (instead of separate dedicated digital signal)
▪Slow analogue signals used to assert TO_IN
▪TO_IN signal not before VCC
If you are in doubt, please
▪Use the mains power adapter that is provided by your distributor and is known to work
properly with your modem.
▪Make sure that your signal and system design is according to the above.
▪Consult our support team that will be more than happy to assist you.
5.2 Configuration of the bit rate on the serial interface
Please note that the module used in the terminal does not support auto baud. The configured data
rate is 115200 baud.
▪Data bits: 8
▪Stop bits: 1
▪Parity: none
5.3 Power cycle the modem
There are two ways to switch off (power down) the modem as described below:
