The 10/100 BaseT LAN is a standard network connection 10/100 BaseT LAN using an RJ-45 connector. There is no auto-sense, meaning it does not recognize straight-through and cross-over cables. 

- For the connection to Ethernet switch **straight-through cable**.
- For the direct PC connection, it is necessary to use a **cross-over cable**.

All touch panel models are equipped with a **PoE **power supply (5”, 7” and 10.1” models) or a **PoE+** power supply (12” models). That means one Cat cable is used for power supply and for data. It keeps the structured cabling safe and does not interfere with concurrent network operation.

> ⚠️ The **length** of the Ethernet cable connecting the touch panel to the network must **not exceed 100 meters**.

> ℹ️ Power over Ethernet is fully compatible with
> ℹ️ 
> ℹ️ - **IEEE 802.3af **(PoE) standard for 5”, 7” and 10.1” models
> ℹ️ - **IEEE 802.3at** (PoE Plus) standard for 12” models.

# Ethernet connection

### Ethernet with PoE Infrastructure

Power over Ethernet needs **compatible PoE or PoE+ Ethernet switches** or injectors currently available by most leading network equipment vendors.

### Ethernet without PoE Infrastructure

Make sure you use:

- **PoE Adapter** for 5”, 7” and 10.1” models
- **PoE+ Adapter** for 12” models.

# Direct PC connection

Make sure you use:

- PoE Adapter for 5”, 7” and 10.1” models
- PoE+ Adapter for 12” models.

Connection steps are as follows:

1. Attach one end of a RJ-45 Ethernet **straight-through cable** to the CUEnet (LAN) port on touch panel and attach the other end of this cable to OUT port of PoE (PoE+) Adapter.
2. Attach one end of a RJ-45 Ethernet **straight-through cable** to the IN port of PoE (PoE+) Adapter and attach the other end of this cable to LAN port of your computer.
3. Attach **power supply** to the PoE (PoE+) adapter.
