    1414Sandbox5 consists of two nodes, i.e. node1-1 and node1-2. Each individual node is connected to one Gnuradio motherboard, and each motherboard in turn has two BasicRX and two BasicTX mounted on it, as show in the following picture. The frequency that the BasicTX operates on ranges from 2 MHz to 200 MHz, and the BasicRX can receive from 2 MHz to 300+ MHz. Since there is no way to put a matching antenna on BasicTX/BasicRX, the two BasicTX/BasicRX daughterboard are connected through two wires, which means the waveform transmitted from BasicTX to BasicRX doesn’t go through air but the two wires. For right now, the TX_B port of the BasicTX on node1-1is wired to the RX_B on the BasicRX on node1-2, and the the TX_A of the BasicTX on node1-1 is wired to the RX_B on the BasicRX mounted on node1-2. Therefore, make sure you have node1-1 as the transmitter and have node 1-2 be the receiver.
