    v27 v28  
    3131 * Turn on the node: {{{omf tell -a on -t node11-10}}}
    3232 * Login into the node: {{{ssh root@node11-10}}}
    33 
    34 After login into the node, there is a {{{flexicon_orbit}}} folder under the home directory of {{{node11-10}}} which contains the source code of this example. You can always retrieve the most recently updated code from [https://github.com/Wimnet/flexicon_orbit here].
     33 After login into the node, a {{{flexicon_orbit}}} folder should exist under the home directory of {{{node11-10:~/}}} which contains the source code of this example. You can always retrieve the most recently updated code from [https://github.com/Wimnet/flexicon_orbit here].

    3837You will need to login into the full-duplex node (by {{{ssh root@node11-10}}}) in two separate terminal windows lo for running the experiment: one for the main full-duplex transceiver UHD program and one for controlling the RF canceller

    40  1. In window 1 (UHD):
     39==== In Terminal 1 (UHD) ====
    4140 * Build the example:
    4241{{{
    43 cd ~/flexicon_orbit/fd_transceiver_simple/uhd
     42cd ~/flexicon_orbit/fd_transceiver_simple/uhd/
    4443mkdir build
    4544cd build
     
    4746make
    4847}}}
    49 
    50  * Check the serial number of the USRP N210 (it should be {{{F331D4}}}): {{{uhd_find_devices}}}
    51 
     48 * Check the conection and serial number of the USRP N210 at {{{node11-10}}}: {{{uhd_find_devices}}}. The serial number should be {{{F331D4}}}.
    5249 * Run the example with IQ rate {{{rate}}}, carrier frequency {{{freq}}}, TX gain {{{tx-gain}}}, and RX gain {{{rx-gain}}}:
    5350{{{
    5451./fd_transceiver_simple --tx-args="serial=F331D4" --rx-args="serial=F331D4" --rate 1e6 --freq 900e6 --tx-gain 10 --rx-gain 10
    5552}}}
    56 The default sine wave has an amplitude {{{ampl = 0.3}}} and wave frequency {{{wave-freq = 100e3}}} (100kHz).
     53 The default sine wave has an amplitude {{{ampl = 0.3}}} and wave frequency {{{wave-freq = 100e3}}} (100kHz). This terminal window will show the power level at RX baseband, after RF cancellation (before digital) and after digital cancellation, respetively.
    5754
    58  2. In window 2 (SUB-20):
     55==== In Terminal 2 (SUB-20) ====
     56 * Build the RF canceller configuration code:
     57{{{
     58cd ~/flexicon_orbit/fd_transceiver_simple/sub20/
     59make
     60}}}
     61 * Check the connection to the SUB-20 device: {{{lbusb}}}. You should see a XDIMAX devices connected to the USB hub.
