EC954 Quick Start Guide

Part 1: Quick Installation (Step-by-Step)

You need to: Unbox → Mount the device → Connect power and Ethernet → (If using cellular) Power off to install SIM and connect antennas → Power on → Set PC to same subnet → Open Web in browser. Then: Scroll down to Part 2 for packing list, LED meanings, mounting details, pinouts, and more.

Must-Read Summary (Before wiring and powering on)

Item	Requirement
Power Supply	12 to 48 V DC, two-pin terminal V+ / V− (or supplied adapter); PWR solid on means powered.
SIM / Micro SD	Must power off to install or remove; no hot-swap.
USB Storage	Supports hot-plug; enter sync before disconnecting to prevent data loss.
Cellular / Wi-Fi / GNSS Antennas	Screw into matching silkscreen SMA connectors; quantity varies by model (see Product Specification Ordering Information).
Factory Restore	Do not power off during the 30-second restoration state (WARN and ERR blinking, STATUS off), or files may be lost.

Step 1: Check the device against the physical unit and identify panel and interface areas

Take the EC954 out of the box and compare it with the front and rear panels below. Locate the Ethernet ports, power terminal, serial ports, SIM slots, antenna connectors, and Micro SD slot.

For the full panel layout, see §2.2.

Step 2: Mount the device to a DIN rail or cabinet

Align the DIN rail mounting plate on the bottom of the EC954 with a standard DIN rail and snap it into place. If you prefer wall mounting, attach the wall mounting kit (purchased separately) to the bottom panel first, then fix the device to the wall.

For detailed DIN rail and wall mounting steps, see §2.4.

Step 3: Connect power and Ethernet

Strip the power cable and insert the V+ and V− wires into the DC terminal block. Tighten the screws. Connect the other end of the power cable to a 12–48 V DC source. Insert an Ethernet cable into any of the four RJ45 ports.

For Ethernet pinouts and serial port wiring, see §2.5.1 and §2.5.2.

Step 4: (If using cellular) Power off to install SIM and connect antennas

Make sure the device is powered off. Use the detachable pin from the accessory box to eject the SIM tray. Place the SIM card into the tray and push it back into the slot. Screw the required antennas into the SMA connectors according to the silkscreen labels.

For SIM slot details and the antenna name table, see §2.5.6.

Step 5: Power on and confirm the device is ready

Apply power. The PWR LED should light up solid. After the system starts normally, the STATUS LED begins blinking.

If STATUS stays off for a long time, a startup abnormality or incomplete factory restore may be occurring. See §2.3 for full LED meanings.

Step 6: Log in via PC and browser

1. Connect your PC to one of the EC954 Ethernet ports with a cable.

1. Set your PC's IP address to the same subnet as the connected port:

Port	Default IP
ETH 1	192.168.3.100
ETH 2	192.168.4.100
ETH 3	192.168.5.100
ETH 4	192.168.6.100

1. Open a browser and enter the corresponding HTTPS URL (for example, https://192.168.4.100:9100 when connected to ETH 2).
2. When the certificate warning appears, accept it and continue.
3. Log in with the default account:
4. Username: adm
5. Password: 123456

Note: Not all EC954 models support the WEB interface management function. Refer to the Ordering Information section in the EC954 Series Edge Computer Datasheet for details.

For SSH login and troubleshooting, see §2.7.

Installation Self-Check

• ☐ Device is securely mounted (DIN rail or wall).
• ☐ Power and Ethernet are connected; if using cellular, SIM and antennas are in place.
• ☐ PWR is solid on and STATUS is blinking.
• ☐ Browser opens the Web login page and login is successful.

If STATUS stays off or WARN/ERR are blinking unexpectedly, check the LED table in §2.3. For a factory restore, see §2.7.

Front Panel

Rear Panel

The EC954 provides an API interface that users can call to detect the state of programmable keys and then implement their own key logic.

2.3 LEDs and Reset Key

The EC954 has 12 LEDs to indicate the power supply and system operating status.

2.3.1 Running Status LEDs

LED	Name	Definition
PWR	Power indicator	Power On and always on
STATUS	System operation status indicator	When the system starts normally, STATUS blinks, and if an abnormality occurs during the system startup phase resulting in a system startup failure; or if the factory restore operation has not yet been completed, STATUS goes out for a long time.
WARN	Warning indicator	The WARN lamp blinks when a warning exception occurs in the system and a system upgrade or factory restore has not been completed.
ERR	Error indicator	The Error light blinks when a serious system error has occurred and a system upgrade or factory restore has not been completed.
SIM1	SIM1 card indicator	Always on when SIM 1 is selected for dialling, long off when SIM 2 is selected for dialling or when dialling is switched off.
SIM2	SIM1 card indicator, always on when selected	Always on when SIM 2 is selected for dialling, long off when SIM 1 is selected for dialling or when dialling is switched off.
USER1	User programmable indicator 1	Default off, user programmable control
USER2	User programmable indicator 2	Default off, user programmable control
4G/5G	Cellular network connection status indicator	Always on after successful dialling

2.3.2 Cellular Signal Strength LEDs

LED	No Signal	Weak Signal (RSSI < -90)	Medium Signal (-90 <= RSSI < -70)	Strong Signal (RSSI >= -70)
L1	OFF	ON	ON	ON
L2	OFF	OFF	ON	ON
L3	OFF	OFF	OFF	ON

2.3.3 Factory Restore LED Indication

In addition to the combination of L1, L2, and L3 signals to indicate cellular signal strength, there is also a set of LED combinations to mark the process of restoring the factory.

LED	State
WARN	Blinking
ERR	Blinking
STATUS	OFF

After the execution of restoring factory settings, the system will perform a reboot. After the reboot is completed, the restoration of the factory is not completed; at this time, the WARN light and ERROR blinking, STATUS off. In this state, the device cannot be powered off, otherwise it may lead to the loss of some files and affect the system function. This state will last for 30 seconds. When the restoration of factory is completed, WARN and ERROR are off and STATUS is blinking.

2.5.7 USB and Micro SD

USB Interface

The EC954 provides two USB 2.0 Host ports, which are mainly used for expanding storage devices and connecting a mouse and keyboard.

EC954 supports USB storage device hot-plugging. It will mount all the partitions automatically. EC954 will mount all the USB storage device partitions to the /mnt/ path. The naming format of the mount folder is usb__. Where is the device node name of the partition and can be a number from 0 to 9.

ATTENTION: Before disconnecting the USB mass storage device, remember to enter the sync command to prevent data loss. When you disconnect the storage device, exit from the /media/* directory. If you stay in /media/usb, the automatic uninstallation process will fail. If this happens, type umount /media/usb to uninstall the device manually!

Micro SD Card

The EC954 has a slot for a MircoSD card. SD does not support hot-swap and needs to be operated with power off. It will mount all partitions automatically. EC954 will mount all micro SD memory card partitions under /mnt/ path. The naming format of the mount folder is sd__. Where is the device node name of the partition and is a number from 0 to 9.

To install a Micro SD card, remove the protective case. Install the Micro SD card into the SD card slot located on the left panel of the EC954.

Attention: Micro SD cards must be installed or removed with the device powered off. Hot-swap is not supported.

2.5.8 mSATA Hard Drive Interface

EC954 supports mSATA hard drive. Factory default does not come with mSATA hard drive. If users have large capacity storage needs, they need to purchase their own mSATA hard drive. You can also consult with InHand for mSATA purchase.

The installation procedure is shown below:

Step 1: Use a screwdriver to open the protective casing of the hard disc.

Step 2: Align the drive with the slot, push it to the right and snap it into place; remove the screws (M2) to secure the right side of the drive.

Step 3: Reinstall the removed protective housing back into the EC954.
