3. Configuration
3.1. Operation Modes
In addition to the serial port configurations such as bit/second, data bit, parity, stop bit, flow control,
Parani-SD has some configurations for Bluetooth. For getting the most out of Parani-SD, user should
understand the following Bluetooth connection schemes.
A Bluetooth device can play a role as a master or slave. Master tries to connect itself to other
Bluetooth device, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth
connection is always made by a pair of master and slave. A slave can be in two modes, Inquiry Scan
or Page Scan mode. Inquiry Scan mode is waiting the packet of inquiry from other Bluetooth devices
and Page Scan mode is waiting the packet of connection from other Bluetooth devices. Every
Bluetooth device has its unique address, called BD (Bluetooth Device) address, which is composed of
12 hexa-decimal numbers.
Parani-SD has 4 operation modes as follows. Each mode can be identified with LED indicators as
illustrated in next section.
Table 3-1 The Parani-SD Operation Modes
Mode Description
Mode0 Parani-SD must be in Mode0, when it is directly controlled by AT commands.
In this mode, there is no response when power on or software reset, and Parani-SD is just
waiting for AT command input. Neither master nor slave is assigned to Parani-SD in mode0.
User can change the configurations of Parani-SD in this mode.
The factory default is set to Mode0.
Mode1 Parani-SD tries to connect the last connected Bluetooth device.
Parani-SD in Mode1 is to be a master and tries to connect the last connected Bluetooth
device. Parani-SD always stores the BD address of the Bluetooth device to which Parani-SD
has connected last time. When Parani-SD is initially used or after hardware reset, there is no
BD address stored in Parani-SD. In this case, Mode1 does not make any sense and mode
change from other operation modes to Mode1 is not allowed. The mode change to Mode1 can
be made after Parani-SD succeeds to connect to other Bluetooth device in Mode0. Once
changed to Mode1, Parani-SD will try to connect automatically the last connected Bluetooth
device whenever power on or software reset.
Parani-SD in Mode1 cannot be discovered or connected by other Bluetooth devices.
Mode2 Parani-SD is waiting for the connection from the last connected Bluetooth device.
Parani-SD in Mode2 is to be a slave and waiting for the connection only from the last
connected Bluetooth device. Just like Mode1, if there is no BD address stored in Parani-SD,
the mode change from other operation modes to Mode2 is not allowed. Once changed to
Mode2, Parani-SD will wait for the connection from the last connected Bluetooth device
whenever power on or software reset.
Parani-SD in Mode2 cannot be discovered or connected to Bluetooth devices other than the
last connected device.
Mode3 Parani-SD is waiting for the connection from any other Bluetooth devices.
Parani-SD in Mode3 acts like in Mode2, but allows any connection from other Bluetooth
device. Most of general Bluetooth device is set to Mode3.
Parani-SD in Mode3 can be discovered and connected from any other Bluetooth devices.

12
3.2. LED Indicators
RS232-Tx and RS232-Rx LED are blinking accordingly when data is transmitted. For small data
transmission, it may be hard to recognize the quick blinking.

Data bite 8
Parity No parity, Even parity, Odd parity
Stop bit 1, 2
Hardware Flow Control Use, No Use
The values in box are the factory defaults. The flow control setting is configurable only through dip
switch.
3.3.1. Data Bit
Parani-SD supports only 8 data bit. In the case of 7 data bit, please contact the technical support.
3.3.2. Hardware Flow Control
Parani-SD plugged into its host system transmits data from host to the other side Bluetooth device.
These data is saved temporarily in the internal buffer of Parani-SD and sent repeatedly until the
transmission is completed packet by packet. When the radio transmission condition is not good
enough to send data promptly, it can cause the transmission delay. If the host sends more data when
the buffer is full, buffer overflow will make Parani-SD malfunction consequently. In order to prevent this
buffer overflow, Parani-SD works as follows.
In case of using hardware flow control, Parani-SD makes RTS be ‘disable’ to stop receiving further
data from the host when the buffer becomes full. RTS will be ‘able’ to begin receiving data again from
the host when the buffer has some room for more data.
In case of not using hardware flow control, Parani-SD clears the buffer to secure the room for next
data when the buffer becomes full. This means the loss of data. As the transmission data becomes
large, the possibility of data loss goes higher.

13
For large data transmission, use of hardware flow control is highly recommended.
3.3.3. Reset to Factory Defaults
To turn back all the configurations to its factory settings, press the reset button depicted in Fig. 1-3.
Press the reset button with a narrow pointed tool like paper clip longer than 1 second. Reset works
only when power is on.
3.3.4. Dipswitch
This feature is only on Parani-SD205. With the combination of 4 slot dipswitches, baud rate and
hardware flow control can be set simply without host computer.
Figure 3-1 The Parani-SD Dipswitch
Upper 3 dipswitches are used for setting baud rate, and bottom dipswitch is used for setting hardware
flow control option. If the baud rate needs to be set out of the range given below, ParaniWIN or
terminal program should be used for extended AT commands. At this time combination of dipswitches
must be complied withAT cmd. Then baud rate will go back to 9600 as default.

blinks 3 times every 2 seconds. Now press again the Pairing Button for 2 seconds until Connect
LED blinks every 0.5 second.
Step 5. Wait for SD1 & SD2 to be connected for a while until Connect LED’s of SD1 and SD2 is lit in
green. It takes about 10 seconds to make a connection. If there are many Bluetooth devices nearby,
it will take a little bit more.
Step 6. Turn SD1 off and on. Connect LED blinks twice in green every 3 seconds.
Step 7. Turn SD2 off and on. Connect LED blinks once in green every 1 second.
Step 8. Now a pair of Parani-SD is configured to make automatic connection, whenever power off and
on.
Just use this pair of Parani-SD like virtual serial cable.
* Note: While pairing is progressing by the pairing buttons, the Command Response will be inactivated
automatically. Then, Parani-SD will not send the response messages such as OK, Connect and
Disconnect.

The icons in the left side window come to the corresponding windows.
In device configuration window, hardware reset can be executed or operation mode and RS232 can
be configured as well. Security option also can be configured in this window.

17
Figure 3-7 Device Setting Window
Parani-SD supports two security options, Authentication and Encryption. If you check the
Authentication option, you must also enter the Pin Code value. If the authentication is activated, the
connection, only between the Master and Slave device that share the same Pin Code, is established.
In case that Parani-SD connects to other Bluetooth device that enables authentication, you must know
the other device’s Pin Code. In general Bluetooth devices, 1234 or 0000 is used as a default value. If
you check Encryption option, the Parani-SD encrypts packets and sends them. The Encryption options
works well in case that only one between Master and Slave uses this option.
Parani-SD has 4 response messages, ‘OK’, ‘ERROR’, ‘CONNECT’, and ‘DISCONNECT’. In some
cases, these responses can affect the host system unexpectedly. To prevent this, user can set the
Command response to ON or OFF.
For Parani-SD100/200, hardware flow control can be configured only by dip switch. Thus H/W Flow
Control option will not work in this case. When the dipswitch value isn’t ATcommand mode, the RS-232
menu will be disabled.
Click [Apply] button to reflect the given options to Parani-SD actually.
Connect(out) icon will show the following window to search and connect other Bluetooth devices.
