3.Installation
Precautions:
Power supply requirements: 24 V DC (12–48 V DC). Pay attention to the voltage
class. The rated current is 0.6 A (1.2–0.3 A).
Environment requirements: operating temperature –25°C to 75°C; storage temperature
–40°C to 85°C; relative humidity 5% to 95% (non-condensing). The temperature on the
device surface may be high. Install the device in a restricted area and assess the
surrounding environment.
Avoid direct sunlight and keep away from thermal sources or areas with strong
electromagnetic interferences.
Install the gateway product on an industrial DIN-rail.
Check whether the required cables and connectors are installed.
3.1.Installing and Uninstalling the Device on a DIN-Rail
3.1.1.Installing with a DIN-Rail
Procedure:
Step 1: Select an installation place and reserve enough space for installation.
Step 2: Insert the upper part of the DIN rail seat onto the DIN rail. Grab the lower end of
the device and revolve it upward in the direction indicated by arrow 2 with gentle force, to
insert the DIN rail seat onto the DIN rail. Check that the device is installed reliably on the
DIN rail, as shown in Figure 3-1 on the right.
Figure 3-1 DIN rail installation schematic diagram
3.1.2.Uninstalling with a DIN-Rail
Procedure:
Step 1: Press the device downward in the direction indicated by arrow 1 in Figure 3-2 to
create a gap near the lower end of the device so that the device isolates from the DIN rail.

Step 2: Revolve the device in the direction indicated by arrow 2, and grab the lower end
of the device and move the device outward. Lift the device when its lower end isolates from
the DIN rail. Then, take off the device from the DIN rail.

3.2.Installing and Uninstalling the Device in Wall-mounted
Mode
3.2.1.Installing in Wall-mounted Mode
Procedure:
Step 1: Select an installation place and reserve enough space for installation.
Step 2: Install the wall mounting bracket on the back of the device by using a screwdriver,
as shown in Figure 3-3.

Step 3: Take out the screws (packaged with the wall mounting bracket), fasten the screws
in the installation positions by using the screwdriver, and pull down the device to make it
secure, as shown in Figure 3-4.
Figure 3-4 Wall mounted installation diagram
3.2.2.Uninstalling in Wall-mounted Mode
Procedure:
Hold the device with one hand and unfasten the screws that fix the upper end of the
device with the other hand, to remove the device from the installation place.
3.3.Installing a SIM Card
IG902 supports Dual SIM card. Unfasten the screws on the cover of the SIM card holder
by using a screwdriver and insert a SIM card.
Figure 3-5 Install SIM card

3.4.Installing an Antenna
Revolve the movable part of the metal SMAJ interface with gentle force until it cannot be
revolved, in which state the outer thread of the antenna connection cable is invisible. Do not
wring the antenna with force by grabbing the black plastic cover.
Figure 3-6 Installing an Antenna
Note
IG900 supports dual antenna: ANT antenna and AUX antenna. The ANT antenna sends and
receives data. The AUX antenna only increases the antenna signal strength and cannot be
used independently for data transmission.
Only the ANT antenna is used in normal cases. It is used with the AUX antenna only when
signal is poor and signal strength must be improved.

3.5.Installing the Power Supply
Procedure:
Step 1: Remove the terminal from the gateway.
Step 2: Unfasten the locking screw on the terminal.
Step 3: Connect the power cable to the terminal and fasten the locking screw.
Figure 3-7 Installing the Power Supply
3.6.Installing the Ground Protection
Procedure:
Step 1: Unfasten the ground screw cap.
Step 2: Put the ground loop of the cabinet ground cable onto the ground post.
Step 3: Fasten the ground screw cap.
Caution
Ground the gateway to improve its interference resistance. Connect the ground
cable to the ground post of the gateway based on the operation environment.
3.7.Connecting the Network Cable
Connect the gateway to a PC directly by using the Ethernet cable.

3.8.Connecting Terminals
Terminals provide the RS232 and RS485 interface modes. Connect cables to the
corresponding terminals before using the interfaces. During installation, remove the
terminals from the device, unfasten the locking screws on the terminals, connect cables to
the corresponding terminals, and fasten the screws. Sort the cables in order.

4.Configuring Network Connection for a
Wireless Gateway
4.1.Connecting to the Gateway
Set the IP address of the management PC and the IP addresses of the GE interfaces of the
gateway to be in the same network segment. The gateway has two GE interfaces: GE0/1 and
GE0/2. The initial IP address of GE0/1 is 192.168.1.1, and that of GE0/2 is 192.168.2.1.
Both interfaces have the same subnet mask 255.255.255.0. The following describes how to
connect GE0/2 to the management PC in the Windows operating system.
( >Network and Sharing Center>Local
Connections>Property>TCP/IPv4>Advanced>IP Address>Add)
Figure 4-1 Gateway Settings
4.2.Logging in to the Gateway
Connect the PC to the gateway directly by using the network cable, start the web browser,
enter https://192.168.2.1 in the address bar, and press Enter to jump to the web login page.
Enter the user name (default: adm) and password (default: 123456), and click OK or press
Enter to access the web configuration page.

4.3.Performing Dial-up on the Gateway
4.3.1.Configuring Gateway Dial-up
IG902 supports two dial-up modes: single card and dual card. The single card mode is
used by default, in which only SIM card 1 is used.
To use the dual card mode, you need to set related parameters. On the page shown in the
following figure, choose Show Advanced Options>Dual SIM Enable, select the primary
card, and save the settings.
Figure 4-2 Dial interface advanced options
4.3.2.Verifying the Gateway Dial-up Status
Choose Network>Cellular in the navigation tree to access the Status page. The page
displays the network connection status, that is, the IP address obtained by the gateway. You
can also verify the dial-up status on a web page.

12
Figure 4-4 the Gateway Dial-up Status
Caution
By default, the DNS of the PC connected to GE0/1 cannot use the IP address of
GE0/1; otherwise, public domain names cannot be accessed. You can enable the
DHCP server or configure another DNS for public domain name access.
