1Introduction
The RTX2254 Bluetooth RF Tester is a highly-optimized, automated test solution for
calibration and functional test in the production of wireless Bluetooth Low Energy (BLE)
devices.
This quick installation guide will describe the hardware and software installation
procedures for the RTX2254 Bluetooth RF Tester –Stand-alone unit, the configuration
and the first test.
Please note that:
A test DUT must be available to complete this quick installation guide.
The DUT must be setup for production test (DTM) with either HCI or 2-Wire
interface. A “Test DUT”with USB is used as example in this description.

4.2 Software Installation File #2
This is a separate delivery containing a demo project which shows how the API is used in
a production test system. Microsoft Visual Studio C++ must be installed.
Please note that:
This is not required for the RTX2254 Bluetooth RF Tester SW to function. If not needed
you can skip this section.
4.2.1 RTX Demo Software Installation
Locate the file: “TestProj_RTX2254_BT-D0110.zip” and unpack it using your
preferred unzip tool.
Please note that:
The most resent version will have the highest version number in the filename. Please use
the newest one for best experience.
Microsoft Visual Studio C++ will automatically start when selecting the file
“TestProj_RTX2254_BT.sln”.
Please enter the COM port number for your system and recompile the project before
running the example.
Refer to the RTX2254 User Manual for more info about the demo test project.

DUT UART COM 20 and 21
RTX2254 COM port 10,11,12
5Software Configuration
The different USB COM port drivers should be configured as shown in the following:
With a powered RTX2254 Bluetooth RF tester and PC, please connect USB cable between
them.
Now the drivers should automatically be installed. If not, then please use the options:
“No, not this time” and “Install the software automatically (Recommended)”,
when or if prompted.
5.1 Configuration of RTX EAI Server
It is strongly emphasized here that it is crucial to configure the RTX EAI Port
Server correctly. Hence, if an error is encountered when launching the RTX2254
Bluetooth RF tester application it is most likely related to an erroneous configuration of
the port server. Please configure it as described below.
5.1.1 Find the COM Port to use
Open the “Device Manager” by selecting “Control Panel”from the Windows main
menu or type “devmgmt.msc” in Windows search.
Then unfold the “Ports (COM & LPT)” line. The COM port numbers shown are system
specific and vary from PC to PC:

Quick Installation Guide V1.10 RTX2254 –Bluetooth RF tester 18
“Test DUT” on USB COM 22
RTX2254 COM port 10,11,12
The “RTX EAI Port Server” needs the communication port number from: “RTX BLE
Tester (COM10)” line
–please note this no. “10”for later use.
The “RTX2254 Bluetooth RF tester SW” needs the communication port number from:
“RTX BLE generator (COM11)” line for the generator communication
–please note this no. “11”for later use.
The “RTX2254 Bluetooth RF tester SW” needs the communication port number from:
“RTX BLE Analyser (COM12)” line for the analyser communication
–please note this no. “12”for later use.
Please note that:
The 2 UART COM ports are shown (See picture above with DUT 0 and DUT 1 as COM20
and COM21). UART is selected by default.
The 2 USB Ports (here only one “Test DUT” is connected as COM22) are only shown when
USB interface is selected from the program.
A minimum of 4 COM port numbers are required. 3 COM ports (Tester, Generator and
Analyzer) for the RTX2254 Bluetooth RF tester and 1 COM port for a test DUT is required
when configuring the program later.
Please note that:
You must first setup the 3 COM ports (Tester, Generator and Analyzer) to be able to
select USB as DUT interface to get the test DUT COM port.

5.1.2 Setup the RTX EAI Server
Please check that the icon “RTX EAI” is present in the task bar, like below picture:
If not started, then start it manually from Windows start button:
“Start →All programs →RTX Telecom →RTX EAI Port Server”
Now right click on the icon on the task bar and select the Setup window (see below).
When selecting the Setup line, the following window will pop-up.
Please note that:
The Transport Layer will be set to Disabled if communication is not possible. In that
case –go here, correct the HW problem and enable it again.
Now please set the “UART” window as shown below.

Quick Installation Guide V1.10 RTX2254 –Bluetooth RF tester 20
Please enter the COM port number from “Device Manager” page. Here it is 10 and be
sure to check that the other fields are set as shown above.
The same apply for the following 2 pages.
Please note that:
The Tester COM port number can also be setup in the RTX2254 application.
In RTX2254 application, set Tester COM = 255 to use the manually setup COM port in the
RTX Portserver application above.
