Installation Instructions
See Chapter 2
Power supply and Grounding
The amount of power device consumes depends on the operational mode it functions. Even higher
power is drawn from the power supply in a moment when the modem is being connected to a

Page 6of 56
power supply. This so-called inrush current can be several times higher than normal current
consumption but will last only few ten milliseconds. For proper operation it is crucial to assure
that the power supply has output power rated to higher than the maximum power consumption of
the device and that the power supply can handle short inrush currents properly. Device can be
grounded using its housing with its DIN RAIL mount. Grounding point is eventually marked to
the housing with Ground – label.
Grounding the antenna is recommended when antenna is located outside on a mast or long pole
where it is prone to lightning strikes or other high energy disturbances.
Grounding is best to locate as near as possible to the expected disturbance to occur, in practice at
the point where the antenna is fixed to a structure. Wiring the antenna ground and/or cable shield
should be done to a ground rail or other reliable common ground with shortest possible cable
length to avoid high resistance ground loops. If grounding cable is needed to be longer thicker
cable should be used accordingly.
It is not recommended to use the mast only as a grounding conductor as its conductivity can’t be
always guaranteed
Safe Installation check list
Electronic devices are sensitive to external influences which should be taken into consideration
while taking the device into operation. Proper place for assembling is necessary for good
performance and long life span. Even though device is built to withstand external vibrations,
shocks, temperature fluctuations and high/low temperatures still those occurrences should be
avoided as much as possible to maximize the durability and longevity of the product. High
temperature decreases the lifespan of the components whereas vibration and shocks weaken the
mechanical structure and can drastically affect the performance in use.
The following points must be taken into account when installing and configuring a device:
All operating voltages of all the equipment concerned must always be switched OFF before
connecting the serial interface cable.
voltage output of the power supply must be stable and with sufficient current capability
check correspondence of Serial interface settings between device (DTE) and the terminal unit
(DCE)
Check placement of device and its antenna:
oantenna should be installed in open space as far as possible from any possible sources of
interference and humans;
onot onto a strongly vibrating surface
ominimize exposure to direct sunlight or excessive humidity.
Check Interference.
This equipment generates, uses and radiates RF and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation; if equipment
causes harmful interference, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following
measures:
oReorient or relocate the receiving antenna

Page 7of 56
oIncrease the separation between the equipment and receiver
oConnect the equipment into an outlet on a circuit different from that to which the
receiver is connected
oConsult the dealer or an experienced radio technician for help
Check settings (APN, SSID) and SIM cards
Accessories
Device is supplied to customers either in bulk packages or in a cardboard box with following
content
Device itself
User manual which includes users' safety and installation instructions
No specific approved accessory is necessary for operating the device for its intended use;
Manufacturer does not provide any such specific approved accessory included.
Dealers will provide a selection of accessories; these might include:
Antennas
Serial data
Power cables and adapters

Figure1-2 IP Modem principle chart
F2x16 consists of the following major components:
- A controlling unit made of a CPU (industrial 32-bit processor)
- WDT module
- Cellular module
- RS232/RS485 serial module
and the following physical Interfaces
- 1 x Power supply (+/-)
- 3 x LED indicators (ACT/Online/Power)
- 1 x RS232 port (RX, TX, GND) and 1xRS485 port(A,B)
-2 x DI/DO + 1 x ADC (DI/DO can be customized to pulse c ounting)
The working principle is the following
After power on, the CPU controlling system functions will communicate with serial modules, it
will send AT commands to cellular wireless module and the wireless module will dial up to
connect to public internet. After device Dial up, online led will turn on, and F2x16 will provide
data transmission for serial devices connected to the switch module and the devices conected to
GPIO interface.
Any configuration is set using the user interface module which can also access to the power
module powering the unit. Power Interface has a standard 3.5mm terminal block interface and
built in phase reversal and over voltage protection, while SIM/UIM standard SIM card slots
support 1.8V/3V SIM/UIM cards and have built in 15KV ESD. This together with its casing
grants good immunity to power spikes, installation mistakes and e.m. discharge, for the safety of
users.
Modems can be set either using AT command or configuration software provided with the modem.

Page 12 of 56
Manufacture will provide specific configure tool to set the parameters of F2X16,user need connect
modem with pc via serial to USB cable,and run the configure tool to set the following
parameters:Data center,Serial port,Work mode,IO port,Dial,Global parameters,Device
management.the proper way of setting those is stated in following paragraphs.
At the same time configure tool interface allow to diaplay the modems logs,it is available to debug
device when user facing some issue; corresponding "logs files" are accessible via the configure
tool. they can send the logs file to manufacture and get techncal support timely.
An internal completely configurable Watch Dog Timer (WDT) can detect if router programs are
running, in order to keep modem always working.
The operating system can be updated both using its configure tool, either locally send AT
command via serial port, or remotely send SMS to configure modem via the cellular network
(require specific SMS format),Backup of complete configuration (settings parameters) of each
modem is possible by saving a proper files on a PC. Restoration of the configuration from one
device to another (e.g. to change a broken unit with a new one) is possible using these files;
customer should not re-enter the configuration parameters in the (new) device itself even if the
two units (the new and the broken one) have different firmware versions. Configuration can be
loaded from one device to another.
Configuration files and methods are compatible when the firmware version is changed; Firmware
upgrade or downgrade will not change nor erase the stored configurations.
Modem can support rich features,include TCP server/client、DDNS、APN、WDT、Data center
backup and Multi-center，and also many common protocol,include Modbus、Http、MQTT.
All the above grants the modem to be secure and reliable quite above its essential requirements.
