In order to connect the Evaluation Board to the PC through the USB port, it is necessary to install the USB-toRS232 drivers (if it has not already been installed). Please refer to the aforementioned referenced User Guide in
Section 1.2 for complete installation instructions.
3.3 Connecting the CEL ZICM35x Module to the PC
After finishing the installation of the CEL MeshConnect ZICM35x Test Tool and loading any necessary drivers,
connect the CEL ZICM35x module to a PC via a USB port.
4. The CEL MeshConnect ZICM35x Program
The CEL ZICM35x Test Tool starts with the Top-Level Window, which supports the connection of the CEL
ZICM35x module to the PC via serial port. Next is the Operation Mode Selection Window, as the Test Tool
supports two types of testing: Hardware Evaluation and ZigBee® Network. The program then proceeds to the Main
Window where user-interactions occur.
4.1 Top-Level Window
The Top-Level Window allows the user to manually specify the connection parameters or lets the application
automatically choose the suitable target. This application supports CEL ZICM35x modules only and it will not
return a response if another device is connected. The user can also use Flash programming to download a new
firmware image to the internal Flash of the target (see Section 6.2).
Features:
•Connect to the specified target via the Communications Settings or Auto Detect options.
•Download a new firmware image to the target via the Flash
Programming Window.
4.2 Auto Detect
The MeshConnect Test Tool can automatically connect to a target
which is connected to the PC, as shown in Figure 6. It starts from
the first COM Port and stops when it reaches the first valid target or
the last COM Port. Within each COM Port, the application detects the
baud rate from 7,200 ~ 128,000 baud. While running auto detect, the
Figure 6
6
progress bar will be displayed to show the status of detection. If
the application detection is successful, the program will show the
Mode Selection window. Otherwise, the application detection has
failed and an error message will appear.
The user must wait five seconds after powering up or resetting
before attempting to communicate with the MeshConnect Test Tool.
4.3 Communication Settings Window
If auto detection of the COM port is not desired, the COM port can
Figure 7
be manually selected. First, select “Communication Settings” in the menu bar.
After selecting “Communication Settings” in the Top-Level Window the Communication Window shown in
Figure 7 is displayed. In this window, use the COM port identified in Section 6.1 and baud rate to connect to
the target. The default baud rate is 115200 bps.
4.4 Operation Mode Selection Window
After successful target detection, the user can select one
of two operation modes as shown in Figure 8:
ZigBee Mode or Hardware Evaluation Mode.
ZigBee Mode
In this mode, a ZigBee network with two nodes is formed
to test the RF performance of the modules. Modules can
either be configured as the Coordinator of the ZigBee
network (shown by the illumination of LED0), or the End
Node (shown by the illumination of LED1). For more
details on ZigBee Mode, please see Section 4.5.
Figure 8
Hardware Evaluation Mode
This mode is used to evaluate the features of the module, such as: RF performance, Packet Error Rate Test
(PER), Range, ADC, etc. LED3 is illuminated on the evaluation board to indicate the successful entry into this
operation mode. For more details on Hardware Evaluation Mode, please see Section 5.1.
4.5 ZigBee Configuration Window
If the user selects ZigBee Mode as the Operation Mode in Figure 8, the user can form a ZigBee network by
choosing the Coordinator option, or join an available network by choosing the End Node option.

Prior to creating or joining a ZigBee network, the user must
provide network information (see Figure 9); the user can choose
the “Use Default Settings” option to use the default values. When
configuring an End Node, please remember to provide the same
PANID and Channel as the Coordinator before clicking “Submit”.
PAN ID: Personal Area Network Identification Number (valid range
0000 ~ FFFE).
RF Power: Power level in network communication (valid range
Figure 9
Power Step -43 ~ Power Step +8).
RF Channel: The channel for network communication (valid range: 2405 ~ 2480 MHz).
Use Default Settings: Takes effect when the user checks the “Use Default Value” check box. The default mode
values will be set as follows:

4.7.4 PER Test (Packet Error Rate Test)
The “PER” Test (Packet Error Rate Test) Tab (shown in Figure 40) can be used to evaluate RF performance in the
user’s own environment. For this demonstration, the Mode C configuration (described in Section 4.7.2.2) is used
in order to allow the separation of the Coordinator evaluation board from the End Node evaluation board. This
makes it possible to measure the Packet Error Rate of the communications link in less-than-ideal circumstances. To
simplify this demo, default settings in the firmware are used. This procedure explains how to configure the board
connected to the PC as the End Node, how to configure the standalone board as the Coordinator, and how to send
a number of packets (from 1 to 65535) from the Coordinator to the End Node. Statistics are then provided showing
the number of “error-free” packets received. From that the Packet Error Rate (PER) can be computed.

5.2.2 PERT Tab
The Packet Error Rate Test tab shown in Figure 46 allows the user to perform the Packet Error Rate Test. The Packet
Error Rate Test is conducted using two evaluation boards, one configured as a Coordinator and the other as the End
Node. The Coordinator sends a defined number of packets with payload data, packet size and packet space. The End
Node counts the number of packets received with the same message code and displays the statistics.
Figure 46
• Payload Data: The message to be sent (minimum 06 bytes, each byte is represented in hexidecimal).
• # of Packets: The number of packets will be transmitted, limited from 1 to 65535 packets.
• Data Payload Source: Defines the message in the data fields.
oPredefined: Fills the Data fields with predefined data, which was generated automatically by the board.
oRandom: Fills the Data fields with random data, which was generated randomly by the board.
oUser Defined: Allows the user to change any of the data values (0x00 ~ 0xFF) in the “Payload” field (minimum: 06 bytes & maximum 121 bytes).
• Start PERT TX: Starts the broadcasting of the specified number of packets. At the target, LED0 will blink.
• PERT Receiver: Number of successfully received packets (data received matches the criteria).
• Clear Stats: Clear the information in target.

5.2.7 External Flash Tab
The flash memory is included for non-volatile data storage (see Figure 52).
Figure 52
• Hex Address: the start offset address of the external flash memory, which allows the write/read operation. This value is in hexidecimal, range from 0 to 0xFFFFFF. (Note: Max address the user should set is 0x200000).
• Length (in decimal): the number of bytes that the user wants to read or write from/to the external flash memory.
(Note: the Min value of the length field is 1, the max value is 256).
• Hex Data to Fill (in hexidecimal): The value that the user wants to program starts from the address which the user specified in the hex address field. This field is represented in 1 byte each.
o If the length is larger than 1, for example: length=10.
o Hex data = 0A.
o Then 10 bytes “0A” will be written to the external flash memory from the start valid hex address.
• Read External Flash: This button allows the user to read the data from the start address. The length of the External Flash is filled in the GUI. The payload (read bytes) are shown in the hyper-
terminal (see Figure 19).
• Write External Flash: This button allows the user to write the hex data with the information specified in the following fields: hex address, length and hex data. If the hex address is larger than 0x200000 or the sum of hex address (in hex) + the length (in hex) > 0x200000, the write operation should not be successful.
• Read ID: The ”Read ID” button allows the user to read the device identification data:
o Manufacture identification (one bytes).
o Device identification (2 bytes).
o A Unique ID code (UID) (1 bytes).
• Erase: The page program instruction allows bits to be reset from 1 to 0. Before this can be applied, the bytes of memory need to have been erased to all 1s (FF h).
o Chip Erase: This function will erase all data on the chip (all values are reset to 1s).
o Sector Erase: With this option, the user can choose the sector number to erase. There are 15
sectors to choose.

6.1 Manually Identifying the COM Port (UEVB Only)
It is necessary to determine the COM port number assigned to the evaluation board so one can
communicate with the module. Using Windows Device Manager on the PC, check that the hardware and
associated drivers have been properly installed (see Figure 54).
Under the “Ports (COM & LPT)” heading a “Silicon Labs
(CP210x USB to UART Bridge (COMx)” entry will be listed.
Take note of the COM port that has been assigned, as it
may be needed later.
