# Connection & Enable

### Device Connection

After confirming the hardware connections, launch the HMI as described in [Launch HMI](/en/docs/wuji-hand-hmi/getting-started). On successful startup, the [Log Panel](/en/docs/wuji-hand-hmi/panels#log-panel) **Operation log** shows the following messages:

```
[INFO] Successfully bound SDO socket to 127.0.0.1:xxxxx
[INFO] Successfully bound PDO socket to 127.0.0.1:xxxxx
[INFO] heart beat timer is enabled
[INFO] connection established
[INFO] Device SN displayed: xxxx.xxxxxx.xxx
[INFO] System Version: x.x.x
```

Click **Connect** in the [Global Panel](/en/docs/wuji-hand-hmi/panels#global-panel). On successful connection:

* The **Spinal board status** in the Global Panel displays: Left/Right hand, system firmware version, online time, e.g. `Left 1.2.0 24m59s`.
* The **STATUS** in the Single-Axis Panel shows `READY`, and data such as motor temperature updates continuously.

### Quick Functional Checks

Click **Run Demo** in the [Global Panel](/en/docs/wuji-hand-hmi/panels#global-panel) to have the hand loop through a preset motion sequence for verifying communication and motion.

<Warning>
  Do not perform other operations while the sequence is running.
