Part 1: Quick Install (Visual Step-by-Step)¶
Must-Read Summary (Before Wiring and Power-On)¶
| Item | Requirement |
|---|---|
| Power Supply | 24 V DC (12–48 V DC), rated current 0.15–0.6 A. Pay attention to the voltage level. |
| SIM Card | Power off the device before inserting or removing the SIM card. |
| Cellular / WLAN Antenna | Tighten according to the silkscreen on the enclosure. |
| Environment | Working temperature: -25 °C ~ 70 °C; storage: -40 °C ~ 85 °C; humidity: 5% ~ 95% (non-condensing). |
Avoid direct sunlight, away from heat source or strong electromagnetic interference. The equipment surface may be high temperature; please consider the surrounding environment before installation. Device should be installed in the restricted area.
Step 1: Check the Panel and Interface Areas Against the Physical Unit¶
Please refer to the physical product for specific panel details. The IR900 series products come in various panel designs, but the installation method is the same for all.
For panel layout and structural dimensions, see §2.2.
Step 2: Mount the Device on a DIN Rail or in a Cabinet¶
Choose an installation location with enough space.
DIN rail (recommended): Slide the upper part of the DIN card holder onto the DIN rail. At the lower end of the device, apply slight upward force and rotate the device to secure the DIN card holder onto the DIN rail. Confirm that the equipment is securely installed.
Wall mount: First attach the wall-mounting bracket to the back of the device with screws, then secure the device to the wall or cabinet with screws.
For detailed installation and removal steps, see §2.4.
Step 3: Connect Power and Ethernet¶
- Remove the terminals from the router.
- Loosen the locking screws on the terminals.
- Insert the power cables into the terminals and tighten the screws.
Connect the router and PC directly using an Ethernet cable.
To enhance the router's overall immunity to interference, it is necessary to ground the router when in use. Depending on the operating environment, connect the ground wire to the router's grounding bolt.
For power specifications, serial port, and grounding details, see §2.5.2. For Ethernet details, see §2.5.1.
Step 4: (If Using Cellular) Power Off to Install SIM and Attach Antennas¶
Make sure the device is powered off.
Push the hole on the left of the SIM card slot to eject it, then insert the micro-SIM card.
Rotate the metal interface clockwise until the movable part cannot be rotated; do not hold the black glue stick to twist the antenna.
The IR900 supports dual antennas: the ANT antenna and the AUX antenna. The ANT antenna is used for both data transmission and reception, while the AUX antenna is solely for enhancing signal strength and cannot be used for data transmission or reception independently. In most cases, using only the ANT antenna is sufficient. You would only use the AUX antenna in conjunction with the ANT antenna when you have poor signal quality and need to boost the signal.
For SIM card slot location and antenna silkscreen details, see §2.5.6.
Step 5: Power On and Confirm the Device Is Ready¶
After confirming all wiring is correct, power on the device. Observe the device LED indicators.
For LED descriptions, see §2.3.
Step 6: Log In via PC and Browser¶
Set the IP address of the management computer within the same network segment as the router's FE port IP address.
| Port Role | Default IP |
|---|---|
| FE 0/1 | 192.168.1.1 |
| FE 0/2 | 192.168.2.1 |
Subnet mask: 255.255.255.0.
Access the default IP address in a browser, enter the username and password (please look at the nameplate at the bottom of the device for login credentials) in the pop-up window, and then access the router's WEB management page. If the browser alarms the connection is not private, show advanced, and proceed to access the address.
For login details and certificate alarm handling, see §2.7.
Post-Install Checklist¶
- ☐ Device is securely mounted (DIN rail or wall).
- ☐ Power and Ethernet cables are connected; if using cellular, SIM and antennas are in place.
- ☐ Device LED indicators appear normal.
- ☐ Browser can open the Web login page and login succeeds.
If you cannot log in, check whether the PC IP settings are correct, or perform a hardware factory reset (see §2.7).
