Introduction
Thank you for your purchase of RT-132B as the Bluetooth To Serial Adapter.
Featuring Bluetooth wireless technology, It is for replacement of standard RS232
cable perfectly, with standard RS232 interface, so it can be easily adopted for
industrial machines with RS232 interface. RT-132B is compatible with all
Bluetooth V.2.0-certified and is backward compatible with v1.1/1.2 devices. You
can connect between your computers (Master) and RS232 devices (Slave) 100
meters away without cables in your working environments.
Security of Bluetooth wireless communication is very strong because it use 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 RT-132B will try to connect automatically whenever powered on after
finishing the device’s parameters configured. It does not require extra software for
operation. No installation of driver and application software.
System OS requirements as Win 98/Me/2000/XP/XP x64.

Antenna Connector
The connector for antenna is a standard Reverse SMA jack. Simply connect
it to a 2.0dBi dipole antenna and it is 50 Ohms impedance and can support
2.4GHz frequency. (The Antenna is changeable for high gain Antenna)
Serial I/O Port of RS-232
Connect the serial I/O RS-232 port into the device as like computers and
serial devices. ( RS-232 RX/TX has been CROSS OVER )
Set-up Button
The purpose is for synchronizing between RT-132B device and “BT RS232
Config Tool” software. After finishing the parameter setup of “BT RS232
Config Tool” software, when you click the icon of “Connect” in “BT RS232
Config Tool” software and then use any point tip to push this button
immediately on the left side of the device. You will see the icon of “Connect”
turn into “Disconnect” and this is meaning successful to active the device.

RT-132B Hardware Installation
1. Connect RT-132B Bluetooth adapter to COM Port of PC and then to connect
DC power adapter and jack into power outlet and DC-in outlet. You will see
the red LED is going to be on and the green LCD will be blinked.
2. After running the BT RS232 Config Tool and finish configuration. Click the
icon of “Connect” in tool software and press the SET-UP button of RT-132B
Bluetooth adapter immediately.
3. The green LED will be turn on. The E-BT232 Bluetooth adapter is active.
There are two types of RS232 devices in field. One is DTE - Data Terminal
Equipment (such as a PC) and the other one is DCE - Data Communication
Equipment (such as a Modem). You can setup your E-BT232 device as what type
of the RS232 device you are going to connect in DTE or DCE mode to work with
it.
At DCE device side meaning is to connect a DTE E-BT232 to the remote DCE
RS232 device (such as a Modem). On the contrary, DTE device side to connect a
DCE E-BT232 to any DTE device, such as a computer device. For example, you
can connect a remote modem with a DTE E-BT232 and meanwhile at PC side,
you can either connect a DCE E-BT232 to it.
