Hardware Installation
1. Fasten the antenna to the Adapter.
2. Connect the Adapter to the serial port of
your PC or serial device.
3. Follow one method below to connect to
an external power source:
A- Use the included USB cable to connect
the Adapter's mini USB connector to a
USB port of your PC.
B- Use a Powered DB9 connector (Pin 9) as
the power supply. This is often used in
POS system.
C- Connect the included battery
power line to the Adapter's Power Line
Connector, and connect the other end
of the power line to batteries (three A /
AA / AAA batteries, or one 3~3.7VDC Li-
Polymer battery). See Figure 5.

4. Switch the Power Source Switch to
"USB/Battery" when powering up the
Adapter through USB or Battery.
Switch the Power Source Switch to
"DB9-Pin9 (5V)" when powering up the
Adapter through powered DB9.
5. The Power LED shows steady red light
indicating the power is on. Once power
is conrmed, go to the next section for
COM port conguration and connection.
COM Port Conguration
1. Congure the parameters of the COM port
through HyperTerminal or other terminal
software. To configure the adapter,
initiate HyperTerminal from the Start Menu.
Note: The conguration windows below
come from software HyperTerminal. For
other terminal software, the windows
may be slightly dierent.
2. Type in "Name", then click OK. See
Figure 6.

4. Follow the instructions in the next
section: "Master/Slave Mode Setup" to
set the Adapter mode.
5. Enable the bluetooth function of the PC,
search the Serial Adapter and make a
connection to it.
Master/Slave Mode Setup
Set the Adapter to be in "Master" mode or
"Slave" mode through terminal software-
ROLE command or DIP command.
Note: Slave mode is the default setting.

11
ROLE Command
1. Type ROLE=M to set the Adapter to the
master role. (Type ROLE=S to set back to
the default.)
Figure9
Figure10
2. Press Enter to see "OK". This means the
setup is successful.
DIP Command
1. The default is DIP=N. Type DIP=Y to turn
on the function of the DIP switch, then
you can manually adjust the S/M switch
to change it to master or slave mode.
Figure 11

12
Group Mode Setup
The adapter is in N/G mode by default. The
adapter can be set to G mode if you have
more than two RS-232 Serial to Bluetooth
Adapters, meaning this adapter is able to
perform single to multiple transmission.
Follow the steps to set the adapter to Group
mode by terminal software:
Type DIP=Y to turn on the function of the DIP
switch.
After the function of DIP switch has turned on,
you can adjust the switch to "G".
