===Power over Ethernet=== | ===Power over Ethernet=== | ||
''' | '''Only in PoE-enabled version. Versions with PoE support have the inscription HLJ-6115ANL on the Ethernet-connector. Connecting Power over Ethernet to a Wiren Board without PoE support (labeled HanRun on the Ethernet connector) will damage the device!''' | ||
''' | '''Connecting PoE with the power supply causes damage to the power supply.''' | ||
Power over Ethernet is supported via cable [http://ru.wikipedia.org/wiki/Power_over_Ethernet#Passive_PoE Passive PoE] with voltage from 7 to 24 Volts. | |||
Power is transmitted in unused pairs: "+" ("-") pair 4-5 (blue, white and blue), "-" ("+") on paired 7-8 (brown, white-brown). Polarity doesn't matter. | |||
See [[Power over Ethernet/en]]. | |||
=== | ===Battery=== | ||
Wiren Board | The Wiren Board allows you to connect a Li-Ion (Li-Pol) battery with a maximum voltage of 4.2 V. When you connect the power, the battery is charged with a current of up to 0.5 A (depending on the load). | ||
There is protection against over-discharge of the battery, at a voltage below 2.9 V the battery is disconnected. However, it is recommended to use protected batteries. | |||
In the current version there is no protection against charging at low temperatures. Be careful, the batteries deteriorate from this. | |||
''' | '''It is necessary to meet the battery polarity!''' | ||
=== | === ADC=== | ||
The user can access 7 ADC channels displayed on the terminals (see table). The maximum measured voltage is 5V. | |||
See. [[ADC/en]]. | |||
=== Terminal blocks=== | |||
