1. Overview
FCC ID: 2A7T8MK8000UWBA
This document provides a quick start guide on testing and evaluation of the MK8000 chipset [1] features
and performance using the MK8000 evaluation kit.
MK8000 evaluation kit has two operation modes --- standalone and MKTool mode.
Standalone mode
oThe EVB starts to work automatically once powered on. The measurement result is
updated periodically in a Windows console through the serial port.
MKTool mode
oThe EVB is controlled by the MKTool [2], and the test result will be shown in the GUI.
MK8000 evaluation kit has one firmware update mode --- ISP (In System Programming) mode.
ISP mode
oWhen EVB is in ISP mode, the firmware of MK8000 chipset can be updated using
ISPTool[3].
2. What’s in the box
The MK8000 evaluation kit includes the following items, as shown in Figure 1.
Two MK8000 EVBs
One 4-element linear array antenna with Anchor EVB
One single element antenna with Tag EVB
Four-wire flat ribbon cables
Two USB-to-serial port adaptors

3. MKSemi EVB Hardware Setup
This chapter provides step-by-step instructions for setting up the evaluation kit.
3.1 Power supply connection
Figure 2 shows the front and back sides of the MK8000 EVB. J105 is the jumper for power supply.
J105(+) connects to VCC and J105(-) connects to GND.
3.2 Power supply configuration
MK8000 EVB supports 1.8~3.6V and 3.6~5.5V power supplies. The default configuration is 1.8~3.6V.

3.3 Function Description of Jumper Pins
The MK8000 EVB has two rows of jumpers that are connected to the I/Os of the chip to offer the
flexibility of configuration and programming. Table 2 describes the functionality of the jumper pins on
the MK8000 EVB.

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.
Table 3 Anchor side hardware connection in standalone mode

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)

3.4.2 Tag hardware setup in standalone mode
Table 4 shows the detail of the Tag hardware connection in standalone mode and Figure 4 shows the
tag after connection. In standalone mode, the USB adapter at the tag side is used for power supply
only.

3.5 MKTool mode hardware setup
The MK8000 EVB MKTool mode needs two MK8000 EVBs and Windows laptops with MKTool
software installed. MKTool is a Windows application program developed by MKSEMI and used to
configure the chip and the EVB, perform and control the MK8000 chipset evaluation. It has a GUI
interface for configuration and results display. Both EVBs need to download the MKTool firmware to
perform the test.
MKTool application sends commands and receives responses and measurement results of MK8000
EVB through the serial port. Table 5 listed the details of the hardware connection in MKTool mode for
both Anchor and Tag sides.
