Network Connection and SD Card Details - RF DC Evaluation Tool

This page describes how to customize the network connection between the ZCU216 or ZCU208 RF Evaluation Tool and the host computer.

Table of Contents


The RF DC Evaluation Tool uses the TCP/IP protocol to communicate between the host computer and the ZCU216. The IP address of the ZCU216 is stored in the SD card and must be known by the GUI via the RF_DC_Evaluation_UI.ini file.

By default, the IP address is set to This address is within the range of the Windows OS Automatic Private IP Addressing (APIPA). Hence the steps below are only necessary if the automatic addressing fails, or when specific network settings are required.

GUI setup

First, we need to instruct the GUI to look for a specific IP address with the steps below:

  1. Navigate to \Distribution_RF_DC_Evaluation_UI\Externals

  2. Edit the "RF_DC_Evaluation_UI.ini" such that the IP address is in a valid range for your lab machine setup. For example:

SD Card

The second task is to change the board image IP address:

  1. Navigate to \Distribution_RF_DC_Evaluation_UI\Externals\image\216

  2. Edit the “” to use the correct matching IP address. For example:

Note: The application auto-start function creates an IP connection at address The autostart IP address can be changed to suit your network restrictions. For the computer to connect to this address, a fixed IP address must be setup. The last part of the IP address must be different.

Host computer network settings

Finally, the host computer must be setup so that its IP address is on the same network range:

  1. On Windows open the “Network Status” ->"Network and Sharing Center", click on the Ethernet connection created.

  2. Click “Properties”, double-click on "Internet Protocol Version 4".

  3. An example of the IP address settings is shown below:
