The USRP E313 is a fully assembled device that includes an USRP E310.
Make sure that your kit contains all the items listed above. If any items are missing, please contact your sales agent or Ettus Research Technical
support immediately.
A host computer with an available USB 2.0 or 3.0 port
•
All Ettus Research products are individually tested before shipment. The USRP? is guaranteed to be functional at the time it is received by the
customer. Improper use or handling of the USRP? can easily cause the device to become non-functional. Listed below are some examples of actions
which can prevent damage to the unit:
Never allow metal objects to touch the circuit board while powered.
•
Always properly terminate the transmit port with an antenna or 50? load.
•
Always handle the board with proper anti-static methods.
•
Never allow the board to directly or indirectly come into contact with any voltage spikes.
•
Never allow any water, or condensing moisture, to come into contact with the boards.
•
Always use caution with FPGA, firmware, or software modifications.
•
Never apply more than 0 dBm of power into any RF input.
Always use at least 30dB attenuation if operating in loopback configuration
In order to use your Universal Software Radio Peripheral (USRP?), you must have the software tools correctly installed and configured on your host
computer. A step-by-step guide for doing this is available at the Building and Installing the USRP Open-Source Toolchain (UHD and GNU Radio) on
and
section of the USRP Embedded Series Hardware Resources for
additional details on which version of the USRP Hardware Driver, UHD, is required. It is recommended to use the latest stable version of UHD that is
available.
If you have a USB stick with the
installed on it, then you may boot your host computer from that. The LiveUSB SDR Environment
does not require anything to be installed on your host computer, and contains a Linux-based environment with the UHD software and the GNU Radio
framework already installed. More information about the
Live SDR Environment Getting Started Guides
Connecting the USRP power supply to the devices will cause the unit to turn on and boot−up. If this is the first time powering on the device, allow the
battery to fully charge before disconnecting the AC power source. Once the device has completed the boot process, you are ready to start using the
device over your preferred method of connectivity (Serial Console, Network, or USB peripherals)!
You can also power the device on and off by pressing the power button. To power the device off, hold the power button down until the button?s LED
turns off (this will take a couple of seconds). To turn the device on, hold down the power button until the LED turns on.
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:
shutdown −-h now
The easiest way to first communicate with your E31x device is by using the USB Serial Console. Connect a micro−USB cable to the Serial Console port
on the E31x 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 E31x using the following parameters: B?aud Rate:?115200, D?ata:?8−bit, P?arity: None, S?top:?1−bit, F?low
Control:?None.
On Linux, the following command will typically handle the serial connection:
sudo screen /dev/ttyUSB0 115200
You may have to change the device name.
For additional information about using the serial console and instructions for communicating with the device over other methods (such as connecting
with SSH over the network or using and LCD screen, keyboard, and mouse), please refer to the UHD Manual online:
http://files.ettus.com/manual/page_usrp_e3x0.html
By default, the E31x device will run a DHCP client on its 1 Gigabit Ethernet port. Assuming your network resolves hostnames (depends on your routers /
switches), if you connect the device to your network, you should see it appear with the hostname e?ttus−e300.?You can then access the device over
SSH.
