- | | VA2 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. That is the center tap of the Ethernet coil between RJ45 pins 3 and 6. | | ||
- | | VB2 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. This pin is directly connected to the network jack of Netzer (RJ45 pins 7 and 8). | | ||

- | | RST | Use this pin to reset Netzer. The signal is low active (this means 0 resets Netzer). The Reset signal can also be used for waking up Netzer from sleep mode (after shut down). The pin is optional and can be left open.| | ||
- | | 3V3 | Pin for power supply. Minimum voltage is 3.1\ V. Maximum voltage is 3.6\ V.| | ||
- | | GND | Ground potential.| | ||

- | | VA1 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. That is the center tap of the ethernet coil between RJ45 pins 1 and 2. | | ||
- | | VB1 | Connection for [[pins#Power-over-Ethernet (PoE)|Power-over-Ethernet]]. This pin is directly connected to the network jack of Netzer (RJ45 pins 4 and 5). | | ||

- | ===== Power-over-Ethernet (PoE) ===== | ||
- | |||
- | The four connections VA1, VA2, VB1 and VB2 are connections from the network socket where a Power-over-Ethernet supply can be connected to. | ||
