Installation & Configuration

Installation

Step 1: Make sure to take full anti-static measures, such as wearing anti-static wrist straps and grounding the workbench.
Step 2: Select the GNSS antenna with appropriate gain (the GNSS systems and frequencies supported by the antenna should be in line with the module), fix it in the non-blocking area, and connect the antenna to the ANT port on the EVK.
Step 3: Connect the EVK to the PC using the Micro-B USB cable.
Step 4: Open the UPrecise software on the PC.
Step 5: Configure the receiver through UPrecise to display the constellation view, data stream, tracking status, etc. For more information, please refer to UPrecise_User Manual.

SD Card Instructions

There is an SD card slot on the UM220-IV N EVK, which is used for data storage and firmware upgrade.
You can also use UPrecise to store data and upgrade the firmware. For more information, see UPrecise_User Manual.

Contents of the SD Card Folder

Before using the SD card, you need to copy the zipped folder “UM220-IVN_
EVK_Suite_V2.0_sdcard” to the card. The folder contains the following items:

fig-4

The “bootloader” folder contains the loader file for the firmware upgrade.
- Unicore has already provided the loader file, which can be used directly.
The “firmware” folder is used to store the firmware file.
The “Log” folder is used for data storage.
The “config.ini” is the configuration file, of which the contents are as follows:

Table 4-1 Description of the config.ini File

Contents	Description
[config]	/

SingleFileSize = 512000000

| The size of a single file.

If the file size exceeds the specified number, a new file will be created. (Hexadecimal format is not supported; please convert the size to a decimal number.)

StartRecordStyle = new

| The recording style after starting up (new or append): Append = log data in the existing file;

New = log data in a new file

WorkBaudrate = 115200| The working baud rate of the UM220-IV N module
LogFileName = log| The name of the log file

update = 0

| 1 = Upgrade the firmware;

0 = Do not upgrade the firmware

Data Storage Instructions

Step 1: Insert the SD card into the PC, and copy the zipped folder “UM220-IVN_ EVK_Suite_V2.0_sdcard” to the card.
Step 2: Unzip the folder and open the “config.ini” file, then set the “update” value to 0, set the “WorkBaudrate” the same as that of the UM220-IV N module and set other parameters as needed (see Table 4-1 for more information).
Step 3: Remove the SD card from the PC, insert it into the EVK, and power on the EVK1.
Step 4: Wait for a while and you can get the logged data in the SD card. During the process, you may use the Micro-B USB cable to connect the EVK to PC in order to check the status of data transmission with a port monitor tool.

Firmware Upgrade Instructions

Step 1: Insert the SD card into the PC, and copy the zipped folder “UM220-IVN_ EVK_Suite_V2.0_sdcard” to the card. Unzip the folder and open “bootloader” to make sure that it contains the loader file. Then, put the firmware file2 in the “firmware” folder.
- For the bootloader and firmware folders, only one file can be stored in each folder.
Step 2: Open the “config.ini” file, and set the “update” value to 1.
Step 3: Remove the SD card from the PC, insert it into the EVK, and power on the EVK.
Step 4: During upgrade, the indicator L1 is off. After the upgrade is finished, the light turns on. You may also use the Micro-B USB cable to connect the EVK to PC in order to check the status of upgrade with a port monitor tool.

If the antenna is not connected, the EVK will output debug information; if you need the positioning information, please connect the antenna before powering on.
Please contact Unicore to get the latest firmware.
