1 Optional add-on

The AAZ-0914A SWR Analyzer hosts a FRC16 connector designed to expand the Analyzer’s features.

2 FD-AAZ-0914-BT2 Bluetooth module

This add-on board (FD-AAZ-0914-BT2) allows AAZ-0914 SWR Analyzer to connect a portable Android terminal

or a Windows Laptop via a Bluetooth link instead of the USB port.

The Bluetooth Module can be powered from AAZ-0914A and it is automatically recognized by the firmware

that disables the USB port and activates the Bluetooth communication channel.

While using Bluetooth function, it is assumed that the USB power is not available and external power will be

required to power AAZ-0914A and BT module. This is achieved by providing Battery Connection on this

board. DC 6 to 12V may be applied to power AAZ and BT

module.

Do not forget to properly positioning the SWRA

“POWER” jumper, refer to the “AAZ-0914A Tech info

document”.


2.1 Testing the Bluetooth Adapter

A “loop-back” test is used to verify that the Bluetooth module is working correctly.

This test connects the BT Adapter transmit pin to its receive pin, so that the terminal software sees an echo

of every character that is sent. The test requires a laptop or a desktop with a BT or using a USB BT adapter,

or Smart phone or tablet using terminal emulation software.

1. On the FoxDelta BT adapter AAZ-0914A-BT2 a header

labeled “LB” is available for this test. Short the header.

2. Connect and pair the BT Adapter to your

PC/Smartphone using the 4-digit code specific for the BT

module version. The most common code is 1234 for

pairing code and HC-05 or HC- 06 for ID modules.

However, refer to datasheet of the module that is used.

2.1.1 Desktop / Laptop

Run a terminal program and connect the “virtual port” created by the BT pairing process. Windows

XP users can run “HyperTerminal”, Windows 7 users can choose any one of the many dumb terminal

programs available from the web.

Parameters to initialize the COM port are:

9.600 Baud, 8 bits, no parity, 1 stop (9600-8N1)

When the BT Device connects, verify that all the characters you key on the terminal program are

echoed back by the BT Adapter.

Loop test jumper


2.1.2 Smartphone / Tablet

Run any “Bluetooth terminal” application. Google Play, Amazon Store and similar websites offer

many free “Terminal Emulator for Bluetooth” Apps.

A good choice is “Bluetooth Terminal” it’s simple and easy to install and use.

Connect the BT Adapter and verify that all the characters you enter from the terminal keyboard are

transmitted and echoed back on the Android device’s screen.

Notice that all characters are shown

twice i.e. echoed.

The first character is what is sent form

the terminal keyboard and the second

is the BT echoed character.


2.2 Bluetooth port on PC

If a laptop/netbook is used, usually these devices have an already integrated Bluetooth port, so no further action is required, go to next paragraph. For a desktop or an old laptop without BT port, an additional USB Bluetooth adapter (dongle key) works fine.

The very old Digicom Palladio USB

adapter, used to test the project, is an

example of this kind of devices.

Download drivers from the producer web site, plugin the dongle key into a USB port, wait until Windows

install it:

A new BT icon is added and port is ready to work.


Verify, this way, the installation from Windows “START”

2.2.1 Initialize the PC – SWRA+BT communication

Connect the Bluetooth adapter to the SWRA unit, power ON the board and, if not yet done, pair it to the PC

Bluetooth port:

2.2.2 Identify the COM port associated to SWRA+BT

Take a note of the port

number

COM30 in this example


2.2.3 Configure SWR Analyzer.exe program

Power on the SWRA+BT and launch “SWR Analyzer.exe”.

You should get the “SWRA unit not found” warning message because now the SWRA+BT is connected to the Bluetooth adapter not to the PC USB port.

Click “Continue” and

navigate to SetUp/Comm,

select “BT0” driver

Save and restart.

Selected driver is USB HID

If the COM port associated to

SWRA+BT is properly listed

(COM30 in the example) next

start SWRA+BT will be

automatically detected,

recognized and linked.

Select BT0


Starting, “SWR Analyzer.exe” searches the port list and detects the SWRA+BT, it memorizes the port number

so next time it will be able to direct access to the port without exploring again the list.


2.2.4 PC troubleshooting - A.

It could happen that removing from the PC and plug-in again the PC USB BT Adapter (dongle key) or just

moving it to a different USB port, Windows loses the link or changes the associated COM port number.

This is caused by the enumeration process executed by Windows to discover the available USB ports and, in

our case, this could impact over the COM port number associated to the SWR BT Adapter and already

memorized by the program.

Try to fix removing the

device and pairing it again.

“SWR Analyzer.exe” restarting won’t find anymore the SWRA unit and it will search the port list for the new

SWRA COM port number.


2.2.5 PC troubleshooting - B.

If for any reason the COM port associated to the SWRA+BT board is not listed or the port name is affected

by spurious / unreadable characters check the field “Force to Connect” and enter the correct port name

(COM8 in the example) on the next field.

“SWR Analyzer.exe” won’t search

anymore the port list, it looks instead

directly to the forced port.


2.3 Android working with SWRA and Bluetooth

Please refer to “SWR Analyzer - Android User Guide” for details about the procedure to pair and

communicate with the SWR Analyzer AAZ0914.


3 GLCD for stand-alone operations

This small breakout board kit is needed if you want to analyze the antenna without using the PC, the GCPU

unit displays the resonance curve on a Graphic Stand-Alone LCD.

Please refer to www.foxdelta.com for the

detailed description of this unit.

Please refer also to the paragraph

“Import Data from SWRA board” and

to the document “SWRA GLCD:

measuring without PC” for more

details.
