1 Introduction
Thank you for your purchase of BS-101 as the Bluetooth To Serial Adapter. Featuring
Bluetooth wireless technology, it is for replacement of standard RS232 or industrial
RS422/485 cable perfectly, with standard RS232 and industrial RS422/485 interfaces,
so can be easily adopted for industrial machines with RS232 or RS422/485 interfaces.
BS-101 is compatible with all Bluetooth V2.1-certified and is backward compatible
with v1.1/1.2 devices. You can connect between your computers (Master) and
RS232/422/485 devices (Slave) 100 meters away without cables in your working
environments.
Security of Bluetooth wireless communication is very strong because it uses the
frequency hopping and 128bit encryption in 2.4Ghz frequency range. Hardware
setting is very easy and simple. The maintenance is very convenience too. One pair
of BS-101 will try to connect automatically whenever powered up after finishing the
device’s parameters configured. It does not require extra software for operation. No
installation of driver and application software.

DC-In Power Outlet
The BS-101 Bluetooth to RS232 / 422 / 485 is powered by a single 9V DC
(Inner positive/outer negative) power supply and 200mA of current. A suitable
power supply adapter is part of the package. Connect the power line to the
power outlet beside of antenna connector and put the adapter into the socket.
If the power is properly supplied, the red color LED (SYS ) will be on.

Antenna Connector
The antenna is a standard SMA jack. Simply connect it to a 2.0dBi dipole
antenna (Standard Rubber Duck) and it is 50 Ohms impedance and can
support 2.4GHz frequency.
Serial I/O Port
Connect the serial data cable between the converter and the serial device.
Follow the parameter setup procedures to configure the converter (see the
following chapters).

Terminal Resistor
The purpose is for compensating signal attenuation in long distance
connection at RS-485/RS-422 I/O. If the switch 1 & 2 are set in “ON” position,
the signal compensation will be activated. To disable the function, just to
push switch 1 & 2 to opposite position.
LED Indicators
SYS (Red)：
It is the power indicator, when the power is on then the LED will blink once
per second.
Pair (Green)：
Before connecting to synchronize between the device and the “BT RS232
Config Tool” software, the green LED will be blinking
After connecting to synchronize between the device and the “BT RS232
Config Tool” software, the green LED (Pair) will be on
RX (Red)：
Data received indicator (When data are received from the network, the LED
will be on.)
TX (Green)：
Data sent indicator (When data are sent out to the network, the LED will be
on.)

6 Config Tool Installation & Setup
When setting up BS-101 adapter for the first time, you have to install and run
“BT1.exe” as “BT RS232 config tool” first in your computer device. The utility CD is
enclosed in the device box. Before you use BS-101 adapter, you have to pair it with
another BS-101 device.
All the BS-101 Bluetooth to RS-232&RS422/485 Adapters must be configured first
before you use it. The purpose of configuration is to pair two BS-101 devices for an
exclusive connection between them, and pairing is done by utilizing Bluetooth
address and PIN code
 Tool Installation
When setting up BS-101 adapter for the first time, you have to install the
utility software of “BT RS232 config tool” in your computer first which is an
executable program in Windows 32 bit environments. BT RS232 config tool
is used to detect and setup the installed.

item of “Role” is chose “Master”. The device will be play like a DTE
mode - Data Terminal Equipment (such as a PC). If the item of “Role” is
chose “Slave” and the device will be play like a DCE - Data
Communication Equipment (such as a Modem)
You can setup your BS-101 device as what type of the RS232 device
you are going to connect in DTE or DCE mode to work with it.
G. Discoverable
The item of discoverable is for allowing (or not ) the device is detected
by other Bluetooth devices.
H. Baud Rate
The item of baud rate is for the pack transmission speed. The baud
rate range is from 120 bps〜115.2K bps and depend on transmission
distance and environments. Normally, the parameter of baud rate is sat
around 9600 bps.
I. Handshake(DSR/DTR)
The item of handshake is set at the “Disable” item.
J. Stop Bit
The item of stop bit is set at the “One Bit” item.
K. Parity
The item of parity is set at the “None” item.

13
Apply “Connect”
After finish the parameters configuration, click the icon of “Connect” in BT
RS232 Config Tool screen and meanwhile press the Synchronous button
immediately on the left side of the device. And then the next screen of
parameters configuration is pop-up. The icon of “Connect” is changed to
“Disconnect” and two icons will be turned into active mode on the bottom of the
BT RS232 Config Tool screen.

14
Apply “Write”
To click the item of “Write”, the meaning is to save all parameters after configuring
into the “BT RS232 Config Tool”.

15
Apply “Read”
To click the item of “Read”, the meaning is to load all parameters as last time
saving from the “BT RS232 Config Tool”. The local address will be updated the
