3.4 Standalone mode hardware setup
The MK8000 EVB standalone mode needs two MK8000 EVBs to perform the evaluation. One EVB is
configured as an Anchor Role and connected to a 4-element linear array antenna, the other EVB is
configured as a Tag role and connected to a single element antenna.
Both EVBs communicate with each other and perform the range and azimuth angle measurement
continuously. The results are sent through the serial port and displayed in a command line terminal of
the Windows PC.
EVB standalone mode has been pre-set and configured with proper configuration and does not need
additional tools or software to control the EVB. It only needs serial port to display the ranging and
angle measurement results at Anchor side.
3.4.1 Anchor hardware setup in standalone mode
Table 3 provides the detail of the Anchor side hardware connection in standalone mode and Figure 3
shows the Anchor after connection.

Operation
J105 (+) VCC Use flat ribbon wires to connect J105 (+) to VCC
J105 (-) GND Use flat ribbon wires to connect J105 (-) to GND
IO_05 RXD Use flat ribbon wires to connect IO_05 to RXD
IO_06 TXD Use flat ribbon wires to connect IO_06 to TXD
IO_02 --
Use flat ribbon wires to connect IO_02 to GND. With this setting, the
EVB will be configured as Anchor (only the EVB with 4-element linear
array antenna should use this setting)
