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-SD100, 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-SD100 has 4 operation modes as follows. Each mode can be identified with LED indicators as illustrated in next
section.
Ì
Mode0
Parani-SD100 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-SD100 is just waiting for AT command
input. Neither master nor slave is assigned to Parani-SD100 in mode0. User can change the configurations of ParaniSD100 in this mode.
The factory default is set to Mode0.
Ì
Mode1
Parani-SD100 tries to connect the last connected Bluetooth device.
Parani-SD100 in Mode1 is to be a master and tries to connect the last connected Bluetooth device. Parani-SD100
always stores the BD address of the Bluetooth device to which Parani-SD100 has connected last time. When ParaniSD100 is initially used or after hardware reset, there is no BD address stored in Parani-SD100. 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-SD100 succeeds to connect to other Bluetooth device in Mode0. Once changed to
Mode1, Parani-SD100 will try to connect automatically the last connected Bluetooth device whenever power on or
software reset.
Parani-SD100 in Mode1 cannot be discovered or connected by other Bluetooth devices.
Ì
Mode2
Parani-SD100 is waiting for the connection from the last connected Bluetooth device.
Parani-SD100 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-SD100, the mode change from other operation modes to
Mode2 is not allowed. Once changed to Mode2, Parani-SD100 will wait for the connection from the last connected
Bluetooth device whenever power on or software reset.
Parani-SD100 in Mode2 cannot be discovered or connected to Bluetooth devices other than the last connected
device.
Ì
Mode3
Parani-SD100 is waiting for the connection from any other Bluetooth devices.
Parani-SD100 in Mode3 acts like in Mode2, but allows any connection from other Bluetooth device. Most of general
Bluetooth device is set to Mode3.
Parani-SD100 in Mode3 can be discovered and connected from any other Bluetooth devices.

Data Bit
Parani-SD100 supports only 8 data bit. In the case of 7 data bit, please contact the technical support.
Ì
Hardware Flow Control
Parani-SD100 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-SD100 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-SD100
malfunction consequently. In order to prevent this buffer overflow, Parani-SD100 works as follows.
In case of using hardware flow control, Parani-SD100 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-SD100 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.
For large data transmission, use of hardware flow control is highly recommended.
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.

Terminal Program
A terminal program is an application that will enable a PC to communicate directly with a modem. If you are using
Windows 98SE or higher version of Windows, HyperTerminal program as it is included as part of the operating system.
Parani-SD100 provides some extended AT commands for its configurations on terminal program.
This manual will explain the method using HyperTerminal. If you need to install HyperTerminal, click start>setting>control
panel>add/remove programs. For more precise information, please refer to Help of Microsoft Windows.
Attach Parani-SD100 to serial port of host computer and power on. Standby LED is lit in green.
Launch HyperTerminal. It can be found in start >programs >accessories >communication >HyperTerminal. Select the
Serial port that Parani-SD100 will be connected to.
Input the same settings into Serial port configuration window as Parani-SD100 settings.
The settings need to be set correctly, otherwise, error message may be shown up on the screen or cause
malfunctioning of Parani-SD100.
Choose the settings in File->Properties->Settings->ASCII setup that let you turn echo on in HyperTerminal; this will show
the response Parani-SD100 sends on the screen.
You now get the HyperTerminal window where you are able to control Parani-SD100 with AT commands. For expanded
AT commands that Parani-SD100 provides, please refer to Appendix A. AT commands.

about 10 seconds to make a connection. If there are many Bluetooth devices nearby, it will take a little bit
more.
6.
Turn SD1 off and on. Connect LED blinks twice in green every 3 seconds.
7.
Turn SD2 off and on. Connect LED blinks once in green every 1 second.
8.
Now a pair of Parani-SD100 is configured to make automatic connection, whenever power off and on.

If the full EIA232 standard is implemented as defined, the equipment at the far end of the connection is named the DTE
device (Data Terminal Equipment, usually a computer or terminal), has a male DB9 connector. Equipment at the near
end of the connection (the telephone line interface) is named the DCE device (Data Circuit-terminating Equipment,
usually a modem), has a female DB9 connector. The cable linking DTE and DCE devices is a parallel straight-through
cable with no cross-overs or self-connects in the connector hoods. If all devices exactly followed this standard, all
cables would be identical, and there would be no chance that an incorrectly wired cable could be used.

Description
In ‘Connect’ status, data from host is transmitted to the other side Bluetooth device,
and any AT command is not accepted but this command, which is not echoed on the
screen.
When Parani-SD100 encounters a character ‘+’ from host, it stops the data transmission
and waits for next 2 characters. If the next 2 characters aren’t both ‘+’, it restart to
transmit data including the first ‘+’ as well. If not, it converts the operation status to
‘Standby’.
If the data from host includes ‘+++’, it will convert the operation status to ‘Standby’
unexpectedly. Notice that Parani-SD100 holds data transmission when it encounters ‘+’,
until receiving next character.
‘+’ is an escape sequence character by default, which is changeable by AT+SETESC.
