Expected result
After quick start, the gateway should open in a browser, use the selected language, have an operating mode, see at least one Modbus line, and show live values for at least one device on the Control page.
Before connecting
Prepare a laptop with Ethernet or a USB-Ethernet adapter, an Ethernet cable, gateway power, and, for RS-485 checks, at least one known Modbus device with known serial parameters. Wired access is the best first step because it does not depend on the site's Wi-Fi profile.
| Parameter | First-access value | Comment |
|---|---|---|
| Gateway Ethernet IP | 192.168.4.2 |
Deterministic Ethernet static profile when no saved configuration exists. |
| Netmask | 255.255.255.0 |
Set the laptop to the same subnet, for example 192.168.4.10. |
| Browser address | http://192.168.4.2 |
If the device is already configured for DHCP or another static IP, use the actual site address. |
| Username | admin |
The current repository bench materials use the local admin account. |
| Password | admin |
Factory local access is normally admin/admin unless delivery notes or the integrator define another password. Change it after login. |
First Ethernet connection
192.168.4.10 with mask 255.255.255.0.
http://192.168.4.2. If it does not open, check laptop IP, cable, power, and VPN/proxy settings.
192.168.4.2. Record the actual site address.
First-start sequence
Three completion paths after local proof
Prove local operation first: the device exists in Setup, appears in Control, values update, and commands return an understandable result. Only then choose the final integration path.
| Mode | Use when | Check after local Control |
|---|---|---|
MQTT_DISABLED |
The gateway remains local with no outside broker or cloud. | Dashboards, local scenarios, Storage, Modbus Log, and clear line statuses. |
UMEC_SPACE |
The recommended high-impact path: dashboards, mobile app, alerts, notifications, and remote control through UMEC Space. | Cloud runtime, MQTT connection, correct provisioning; BLE pairing is available only in this mode. Check the gateway in Dashboard, mobile access through UMEC Home or UMEC Business. |
MQTT_GENERIC |
Data must be published to a third-party MQTT broker. | Broker URL, auth/TLS, redacted password, publish/subscribe topic preview, and actual message publishing. |
Final check after adding a device
Minimum settings by area
| Area | Action | Healthy signal |
|---|---|---|
| Login | Choose language and sign in with an operator or administrator account. | The protected shell opens with runtime status pills and navigation. |
| Settings | Set operating mode, network, time, and line modes. | The section shows success or a clear reason why saving was rejected. |
| Setup | Create line/device data, channels, and commands. | The device appears on the selected line and is not mixed with another line. |
| Control | Select the device, check values, and mark channels for charts. | Values are fresh, errors are visible, and charts update without page jumps. |
| Storage and logs | Confirm that configuration files and logs are available for service work. | The file tree opens and the selected file can be viewed or downloaded. |
What not to do in the first hour
- Do not enable external integration before local polling is verified.
- Do not edit JSON in Storage when the same task can be done through Setup.
- Do not use factory reset for a normal communication issue with one device.
- Do not confuse RTU transparent mode and TCP mode: TCP is a separate integration channel.

Where to go next
If first start is successful, continue with Commissioning. For regular use, read Operations. For operator screens, move to Dashboards.
