Introduction
Thank you for your purchase of 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. This adapter 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 RS232/422/485 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 this adapter 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.
System OS requirements as Win 98/Me/2000/XP/XP x64 / VISTA.

DC-In Power Outlet
The 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
Serial I/O Port of RS232&RS422/485
To 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 ).

Terminator
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.
Set Button
The purpose is for synchronizing between this adapter 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 the meaning is successful to active the device.
