 ==Battery (E312 Only)==
 The USRP E312 is equipped with an integrated 3.7V, 3200mAh lithiumion battery cell. After unboxing the USRP E312 , plug in the power adapter to an AC power source and fully charge the battery. This process with take approximately 2 hours. Do not leave the USRP E312 unit plugged in for more than 24 hours.

 When the power button status LED indicates at “Temperature Error” or “Charger Error” (codes 8, 9, 11, or 12), power off the USRP E312 unit and allow it to cool down to room temperature. Then, plug in the USRP E312 to and AC power source and fully charge the battery.

 ==Serial Console Connectivity==
 The easiest way to first communicate with your E312 device is by using the USB Serial Console. Connect a microUSB cable to the Serial Console port on the E312 and connect the other end to a PC. The console will appear as an “FTDI Serial Device”  thus, it will likely appear as a ttyUSB device in Linux or a COM port on Windows. In Windows, you will need to edit the properties of the device in ‘Device Manager’ and ‘Enable VCP’. On the PC, open a serial terminal to the E312 using the following parameters: Baud Rate:115200, Data:8bit, Parity: None, Stop:1bit, Flow Control:None.

 Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges, the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage.

 To avoid damaging the file system and causing any corruption, do not turn the device off with the power button without first shutting down the system. Use this command to cleanly and properly shut the system down:

-The rx_ascii_art_dft utility is a simple consolebased, realtime FFT display tool. It is not graphical in nature, so it can be easily run over an SSH connection within a terminal window, and does not need any graphical capability, such as X Windows, to be installed. It can also be run over a serial console connection, although this is not recommended, as the formatting may not render correctly.
