What is Bluetooth?
1. Features of Bluetooth
1) Objectives of Bluetooth : To Realize Wireless Communication for Short Distance with Low
Power Consumption, High Reliability, and Low Cost.
2) Frequency in Use: To Use ISM(Industrial, Scientific, Medical) Band which does not require
any permission to use.
- 2.400 – 2.4835 GHz, 79 channels
- 2.465 – 2.4835 GHz, 23 channels (in France)
3) Transmission Rate : 1Mbps
4) Transmission Output : 1mW(10m, Class2), 100mW(100m Class1)
5) Network Configuration : Configured with Master and Slave relation. A Bluetooth unit shall
allow simultaneous connections up to 7 devices (in case of ACL).
6) Reliability : To Guarantee stable wireless communication even under severe noisy
environment through adopting the technique of FHSS (Frequency Hopping Spread Spectrum).
2. Operation of Bluetooth
1) Once the Master will inquire the Slave, the Slave will respond to the inquiry to the Master.
2) When the information of Slave will agree with that of the Master, the interconnection will be
achieved to transmit the data.

- FB755AC & FB755AS module
- PC Interface Kit
The PC Configuration could be processed with two significant ways.
First one is to use Config tool provided by FIRMTECH Co., Ltd.
Second one is to use serial communication program (Hyper Terminal, minicom) providing OS.
The respective way of setting is as follows.
8-1 PC Configuration using Congfig tool
(1) Connect FB755AC & FB755AS to PC Interface Board, then connect to COM port(Serial port)
of PC.
(2) Set Config Select Switch of PC Interface Board OFF and then turn the power ON.
(3) Execute Config tool.

2 WRITE STATUS Button : To store the value set in the PC configuration window into the product
3 Factory Setup Button : To reset all the PC configuration value to the factory set value.
(7) To summarize the setting up the config tool, follow the procedures as under.
- To strore the set value upon completion, please be sure to click WRITE STATUS button.
- Click READ STATUS to read in the stored configuration value to certify the they are correct or
not.
- If you want to set as the status first received, click Factory Setup to reset the first received
value.
- Since the config tool was made based on AT command of the product, it is possible to
represent the ongoing command language and its status at the form of status value and
message window.

8-2 PC Configuration using Serial Communication(Hyper Terminal) Program
8-2-1 To execute Hyper Terminal
To set up PC configuration using Hyper Terminal, following works will have to be done before
power is authorized to the PC connected with the product.
To accomplish the PC configuration, serial communication program is required. Here Hyper
Terminal will be used for explanation.
(1) Set the Config Select on the PC Interface Board (Jig Board) ON.
(2) Execute in the order of [start]Æ[All Programs]Æ[Accessories]Æ[Communications]Æ
[Hyper Terminal], then connection window will appear on which enter appropriate name and
click.
(3) When the comes up, select the COM port connected to FB755AC & FB755AS,
and clicks the Acknowledge button.
- 22 -
FB755AC & FB755AS Version 1.0.3
(4) When Registration Information Window comes up as on , select Bit per
second : 9600, Data bit : 8, Parity : none, Stop bit : 1, Flow control : none, which will
execute Hyper Terminal.
- 23 -
FB755AC & FB755AS Version 1.0.3
(5) Basically, the Hyper Terminal does not show the entered character.
To make sure of the
entered character, select [File]Æ[Properties] on the Menu, then registration information
window will appear shown as on , click the ASCII Setup button.
(6) As shown on , “Check Echo typed characters locally” and come out
pressing the acknowledge button. Now the Hyper Terminal program setting procedure is
completed to use PC Configuration.
- 24 -
FB755AC & FB755AS Version 1.0.3

8-2-2 How to Use PC Configuration Menu
The user will select the menu want to change. To select the menu, you may just select the
number given on the left side.
For example : To change “DEVICE NAME”, enter : [“0”]Æ[Enter]
Note : At condition, Pressing Reset button for more than 2 seconds will reset
all the configured values to the initial status (factory preset status).
Following is the order to use the menu.
(1) The execution will only be executed by pressing the “Enter” key.
