Note *:

Bluetooth v2.0 supports improved AFH function. AFH function is to mitigate the interference
between WiFi and Bluetooth radios by automatically avoiding the active WiFi channel from
Bluetooth link. However, AFH does not provide a complete solution making WiFi and Bluetooth
work together in harmony. It is highly recommended for users to test their wireless system
enough before deployment since the overall system performance is affected by various
environmental factors such as distance between them.

Figure 2-4 USB Serial Port

3. Configuration

3.1. Operation Modes

In addition to the serial port configurations the Parani-SD1000U also requires some settings for
Bluetooth. For getting the most out of Parani-SD1000U, 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 devices, and slave is waiting to be connected from other Bluetooth devices. A Bluetooth
connection is always made by a pair of master and slave devices. A slave can be in two modes,
Inquiry Scan or Page Scan mode. Inquiry Scan mode is waiting for a packet of inquiry from other
Bluetooth device and Page Scan mode is waiting for a packet of connection from other Bluetooth
device. Every Bluetooth device has its unique address, called BD (Bluetooth Device) address, which is
composed of 12 hexa-decimal numbers.

Parani-SD1000U has 4 operation modes as follows. Each mode can be identified with LED indicators
as illustrated in next section.

Table 3-1 The Parani-SD1000U Operation Modes

Mode

Description

Mode0

In this mode, there is no response when usb port connect or software reset, and Parani­SD1000U is just waiting forAT command input. Neither master nor slave is assigned to
Parani-SD1000U in mode0. User can change the configuration parameters of Parani­SD1000U in this mode.

Parani-SD1000U must be in Mode0, when it is directly controlled by AT commands.
The factory default is set to Mode0.

Mode1

Parani-SD1000U tries to connect the last connected Bluetooth device.
Parani-SD1000U in Mode1 is to be a master and tries to connect the last connected Bluetooth
device. Parani-SD1000U always stores the BD address of the Bluetooth device to which
Parani-SD1000U has connected last. When Parani-SD1000U is initially used or after hardware
reset, there is no BD address stored in Parani-SD1000U. In this case, Mode1 will not be able
to work properly. The mode change to Mode1 can be made after Parani-SD1000U succeeds
to connect to one other Bluetooth device. Once changed to Mode1, Parani-SD1000U will try to
connect automatically the last connected Bluetooth device whenever the unit is connect to usb
port or software reset.
Parani-SD1000U in Mode1 cannot be discovered or connected by other Bluetooth devices.

Mode2

Parani-SD1000U is waits for a connection from the last connected Bluetooth device.
Parani-SD1000U 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 Parani­SD1000U, the mode change from other operation modes to Mode2 is not work properly. Once
changed to Mode2, Parani-SD1000U will wait for the connection from the last connected
Bluetooth device whenever the unit is connect to usb port or software reset.
Parani-SD1000U in Mode2 cannot be discovered or connected to Bluetooth devices other
than the last connected device.

Mode3

Parani-SD1000U is waiting for the connection from any other Bluetooth devices. In Mode 3 the
Parani-SD1000U is discoverable and can be connected to by other Bluetooth devices.

3.2. LED Indicators

Serial-Tx and Serial-Rx LED will flash accordingly when data is transmitted. For small data
transmissions, it may be hard to recognize the quick flashing action of the LED.

The values in box are the factory defaults. The flow control setting is configurable only through dip

3.4. Data Bit

Parani-SD1000U supports only 8 data bit. In the case of 7 data bit and even/odd parity, use SD 8 data
bit and none parity. At this time, master and slave are Parani-SD, Parani-ESD or Parani-MSP series.
But 7 data bit and none parity is not support.

3.5. Hardware Flow Control

Parani-SD1000U plugged into its host system transmits data from host to the other side Bluetooth
device. This data is saved temporarily in the internal buffer of Parani-SD1000U 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 a transmission delay. If the host sends more data
when the buffer is full, buffer overflow will make Parani-SD1000U malfunction consequently. In order
to prevent this buffer overflow, Parani-SD1000U works as follows.

When using hardware flow control, Parani-SD1000U disables RTS so that it stops receiving any
further data from the host when the buffer becomes full. RTS will be re-enabled again to begin
receiving data from the host when the buffer has created more room for more data.

When hardware flow control is not being used, the Parani-SD1000U clears the buffer to secure room
for the next data when the buffer becomes full. This can mean a loss of data may occur. As the
transmission data becomes large, the possibility of data loss becomes greater.

For large data transmissions, the use of hardware flow control is highly recommended.

3.6. Reset to Factory Defaults

To set to its factory default parameters, press the reset button, depicted in Fig. 3-1. Press and hold (for
at least 1 sec) the reset button with a narrow pointed tool like paper clip. Reset works only when
SD1000U is connect to usb port.

3.7. Dipswitch

With the combination of 4 slot dipswitches, baud rate and hardware flow control can be set.

Figure 3-1 The Parani-SD1000U Dipswitch

Upper 3 dipswitches are used for setting the baud rate, and bottom dipswitch is used for setting
hardware flow control option. If the baud rate needs to a baud rate not shown below, ParaniWIN or
terminal program should be used to set these speeds. To set a baud rate not shown below the
dipswitches should be in the S/W Config setting. When in the S/W Config setting the baud rate will go
back to 9600 as default.

3.8. Pairing Button

Parani-SD1000U provides Pairing Button for instant configuration without a PC to make an automatic
connection between two Parani-SD1000Us. In this example we will refer to the two Parani-SD1000Us
as SD1 and SD2. (Only single connection mode)

Step 1. Turn on SD1 and SD2 and reset both of them by pressing Factory Reset Button.
Step 2. Press the Pairing Button of SD1 for 2 seconds until Mode LED blinks 3 times every 3 seconds.

Keep connect to usb port.

Step 3. Press the Pairing Button of SD2 for 2 seconds until Mode LED blinks 3 times every 3 seconds.

Now press again the Pairing Button for 2 seconds until Mode LED blinks every second.

Step 4. Wait for SD1 & SD2 to connect to each other until the Connect LED’s of SD1 and SD2 blink

every 1 second. It takes about 10 seconds to make a connection. If there are many Bluetooth

devices nearby, it may take longer.
Step 5. SD1 disconnect to usb port and connect to usb port. Mode LED blinks twice in green every 3
seconds.

Step 6. SD2 disconnect to usb port and connect to usb port. Mode LED blinks in green every second.
Step 7. Now SD1 and SD2 are configured to make automatic connection to each other, whenever they

are connected to usb port.
Using a pair of Parani-SD1000U in this fashion is similar to that of using a wireless serial cable.
* Note: When using the pairing buttons, the Command Response option will be deactivated

automatically. The Parani-SD1000U will not send the response messages such as OK, Connect and
Disconnect.

When the ParaniWin software is able to access the Parani-SD1000U properly, the icons in the left side
window come will become available for use.

In device configuration window, hardware reset can be executed or operation mode. Security option
also can be configured in this window.

Figure 3-6 Device Setting Window

Parani-SD1000U supports Authentication and Encryption. If you enable the Authentication option, you
must also enter a Pin Code value. If the authentication is enabled, the connection, between the Master
and Slave device must share the same Pin Code. In case that Parani-SD1000U connects to another
Bluetooth device, that requires authentication, you must know the other device’s Pin Code. In general,
most Bluetooth devices have a pincode of 1234 or 0000. If you check Encryption option, the Parani­SD1000U will encrypt packets and sent to the device. The Encryption options works well in case that
only one of the devices between Master and Slave use the Encryption option.

Parani-SD1000U 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-SD1000U, hardware flow control can be configured only by dip switch. And parity, stop bit
can be configured only SW config mode. Thus H/W Flow Control option will not work in this case.
When the dipswitch value isn’t ATcommand mode, the Baud Rate menu will be disabled.

Click [Apply] button to apply any changes made to the Parani-SD1000U.
Connection(out) icon will show the following window to search and connect other Bluetooth devices.

Figure 3-7 Connection (out) Window

Click [Search] button to search nearby Bluetooth devices. Once several Bluetooth devices has been
found, select one of the devices and click the [Connect] button. The selected Bluetooth device must be
discoverable and connectable. Click [Disconnect] button to cancel the connection.

After the connection has been established, you will be able to test signal strength by pushing the
START button.

Figure 3-8 Signal Strength Test

The signal strength test shows LInkQuality and RSSI values. The closer LinkQuality is to 255 and
RSSI is to 0, this means the Parani-SD1000U has a good connection to the connected Bluetooth
device. In general, the wireless connectivity is at its best within 10 meters. You can push the STOP
button at anytime in order to terminate the signal strength test. The signal strength test will continue
until the STOP button is pushed. If you close the ParaniWIN Window without pushing the STOPbutton,
you must restart Parani-SD1000U to terminate the test.

Connection(in) icon will show the following window, which enables the Parani-SD1000U to wait for a
connection from another Bluetooth device. If the waiting time is set to 0, Parani-SD1000U will
continually wait for connection until [Cancel] button is clicked.

4. Multiple Connection Mode

4.1. Overview

Parani-SD1000U supports multiple connections up to 4 slave units. There are two types of multiple
connection modes: Multi-Drop Mode and Node Switching Mode.

Figure 4-1 Multi-Drop Mode

In Multi-Drop Mode a master unit can connect to maximum 4 slave units at the same time and they
transfer data bi-directionally as in Figure 4-1.

Figure 4-2 Node Switching Mode

In Node Switching Mode, the master unit maintains multiple connections with maximum 4 slave units
but only one connection with one slave unit is active and data is transferred as shown in Figure 4-2.
After connected to slave, master acts command mode. Active slave is selected by AT commands.

4.4. Notes

When large data exchange occurs in Multi-drop mode without flow-control enabled, the master unit
may experience data loss. It may also experience occasional disconnections and/or system rebooting
especially when bi-directional communication happens. It is strongly recommended to perform
extensive performance test before any real world field applications.
The master unit would try to connect all slave units specified by S-register 46, 54, 55 and 56. If non­existing or inactive slave addresses are entered in these S-registers, the overall performance will
degrade due to frequent connection trials to non-existing/inactive slaves. It may also force
disconnections for overall performance and outputs disconnect messages repeatedly.

Node-switching mode provides nearly equivalent performance as single connection mode. It is always
recommended to use flow-control for both of Multi-Drop Mode and Node Switching Mode.

Appendix B: S-Register

S-registers contain 52 parameters for the Parani-SD Series. These are stored in flash memory and the
values will be saved unless hardware reset is executed. The value of S-register can be accessed and
changed with ATS command. Some S-registers not shown below are set to maximize the performance
of Parani-SD Series. Thus it is not recommended to change these S-registers.
Changing the values of S-register can only be done in the Standby mode. Turn Parani-SD off and on.

B.1. S1: Force to Reconnect (default 1)

S1=0, Parani-SD in Mode1 does not try to reconnect when disconnected.
S1=1, Parani-SD in Mode1 keeps trying to reconnect when disconnected.

B.2. S3: Stream UART Policy (default 0)

S3=0, the priority of UART streaming is throughput.
S3=1, the priority is latency, which minimizes the delay of data transmission. This is useful in case of

transmitting very small data quickly.
When this value is 1, in order to minimize latency, Parani-SD sends the received data immediately.
When this value is 0, the Parani-SD maximizes throughput, the Parani-SD stores received data for a
short time and sends a large data packet. If the packet length is less than 100 bytes, having latency
being the priority is recommended. If the packet length is more than 100 bytes, having throughput as
the priority is recommended. Also, if you want to use high baud rate, throughput priority will be more
effective. Just for reference, the buffer length for receiving data is 2 Kbytes.

B.3. S4: Enable Remote Name Query (default 1)

S4=0, Parani-SD will query only the BD address. This speeds up the inquiry process.
S4=1, Parani-SD will query the BD address, device name and class of device.
When this value is 1, Parani-SD finds not only BD address but also friendly name. When this value is
0, Parani-SD finds only BD address. When set to 0 this will make queries much faster. When using the
pairing button, finding friendly name will be omitted automatically.

B.4. S6: Enable Low Power Mode (default 0)

S6=0, deactivate Low Power Mode.
S6=1, activate Low Power Mode.
This value decides whether Parani-SD works in Low Power Mode or not. When this value is 0, Parani­SD works only in active power mode. When Parani-SD works in Low Power mode, delay in
transferring data may occur.

B.5. S10: Enable Response Message (default 1)

S10=0, Parani-SD does not send response messages to the host system.
S10=1, Parani-SD sends response messages to host system.
This value decides whether Parani-SD sends response messages such as OK, ERROR, CONNECT,
DISCONNECT or not. When this value is 0, Parani-SD will not send any response messages. If the
response messages conflicts with your host programs or devices that is connected to Parani-SD,
change this value to 0.

B.6. S11: Enable Escape (default 1)

S11=0, Parani-SD does not allow escape sequence characters. The operation status of Connect

cannot be changed to Standby. Since the Parani-SD skips the process of detecting escape

sequence characters, more efficient data transmission can be had.

S11=1, Parani-SD allows for the escape sequence character. Whenever it is needed, the Connect

status can be changed to Standby.

B.7. S12: Clear Data Buffer When Disconnected (default 1)

S12=0, Parani-SD does not clear the data buffer received from host system when disconnected.
S12=1, Parani-SD clears the data buffer when disconnected.

B.8. S13: Enable DCD Signal (default 1)

S13=0, DCD signal off
S13=1, DCD signal on

B.9. S14: Enable DTR Transfer (default 1)

S14=0, DTR/DSR signal is transferred in a loop-back fashion.
S14=1, DTR signal is transferred to DSR of remote device.

B.10. S15: Enable Disconnect by DTR (default 0)

S15=0, DTR signal cannot release the connection.
S15=1, The Bluetooth connection can be released when DTR signal is off.
This value decides whether Bluetooth connection is released when DTR signal drops or not. If this
value is 1, you can use DTR signal in order to disconnect Bluetooth connection.

B.11. S22: Faster Connection (default 0)

S22=0, none
S22=1, page scan
S22=2, inquiry scan
S22=3, page/inquiry scan
Connecting time is average 1.5sec faster than normal mode.

B.12. S23: Intercharacter Timeout Setting (default 0)

S23=0 : Not used
S23=1 : 1 x S26
S23=2 : 10 x S26
S23=3 : 100 x S26

B.13. S24: Maximum Number of Inquiry Result (default 15)

The maximum number of inquiry list can be controlled. This value is up to 15.

B.14. S26: Intercharacter Timeout (default 0)

This value describes time interval between characters used to separate the data from serial port. If
there is no more data coming from serial port in this value, data is sent to client.

S23=1 x S26=50 : Timeout-> 50msec
S23=2 x S26=50 : Timeout-> 500msec
S23=3 x S26=3 : Timeout-> 300msec

Intercharacter Timeout * Optimal Value(S23 x S26)

* When 10 bytes data are sent every intercharacter timeout, they are sent separately by 10 bytes at

the optimal value. If the intercharater timeout is set below the optimal value, the date will be put
together and sent by 20, 30, 40 bytes or more.

B.15. S28: Escape Sequence Character (default 43)

The decimal number of the ASCII code of escape sequence character can be controlled. The initial
value is 43, the ASCII code of ‘+’.

B.16. S31: Page Timeout (default 20)

This is the timeout in seconds to attempt connection with the ATD command. After this timeout expires,
the Parani-SD will restart automatically. If this value is 0, Parani-SD will attempt to connect without
restarting. It must set at 5 second units.

B.17. S33: Inquiry Timeout (default 30)

This is the timeout in seconds to execute inquiry scan.

B.18. S37: Supervision Timeout (default 5)

This is the timeout to presume disconnection, which is set to 5 seconds initially. The smaller the value
becomes, the more quickly Parani-SD can detect an abnormal disconnection. But when the
communication is suspended, it may be regarded as disconnection. This value should be greater than
the Slave Disconnect Timeout(S57). (Slave unit depends on the value of master unit.)

B.19. S43: COD (default 001F00)

This value describes the sort of the bluetooth device and is editable.

B.20. S44: COD Filter (default 0)

This value is used to filter the sort of the bluetooth devices on inquiring. All the bluetooth devices are
inquired in case of 0. In case of 3E0100, bluetooth devices with COD 3E0100 are inquired.

B.21. S45: Inquiry Access Code (default 0x9E8B33)

Inquiry access code is used during inquiry state. The reserved IAC addresses are 0x9E8B00 ~
0x9E8B3F. The general inquiry IAC is 0x9E8B33.
Parani-SD is able to find the Bluetooth devices that are configured as the same IAC

B.22. S46: BD Address of Last Connected Device

This saves the BD address of the Bluetooth device connected most recently in single connection
mode. This saves the Task1 BD address of the Bluetooth device connected most recently in a multiple
connection mode.

50ms 180
100ms 235
200ms 340

B.23. S48: Low Power Max Interval (default 5000)

This is the max interval value to use low power mode, which is set to 5000 initially. (5000 x 625μsec =

3125msec)

B.24. S49: Low Power Min Interval (default 4500)

This is the min interval value to use low power mode, which is set to 4500 initially. (4500 x 625μsec =

2812msec)
A small interval increases power consumption, a large interval increases latency.

B.25. S52: Low Power Timeout (default 5)

This is the low power timeout value, which is set to 5 initially.(5sec)
During no data transmission in the timeout, Parani-SD will be in low power mode to save the power.
Therefore, it takes a few seconds to wake the Parani-SD out of low power mode.

B.26. S54: BD Address of Last Connected Device

This saves the Task2 BD address of the Bluetooth device connected most recently in a multiple
connection mode.

B.27. S55: BD Address of Last Connected Device

This saves the Task3 BD address of the Bluetooth device connected most recently in a multiple
connection mode.

B.28. S56: BD Address of Last Connected Device

This saves the Task4 BD address of the Bluetooth device connected most recently in a multiple
connection mode.

B.29. S57: Slave Disconnect Timeout (default 3)

This S57 register value defines the time period in seconds that a master unit waits in case a slave unit
does not receive the data sent from the master. For this time period, the master unit will not send data
to all slave units if any slave unit does not receive the data. If the slave unit does not receive the data
after this time period elapses, the master unit will disconnect the connection with the problematic slave
unit. The value should be greater than 0 and smaller than the Supervision Timeout(S37).

B.30. S58: MAX TX POWER (default 0)

This value describes the peak output power. Setting this causes rebooting and applying. (There can
be a little deviation depending on the each device.)
Parameter dBm
0 Use chip setting.
1 -12
2 -8
3 -4
4 0
5 4
6 8
7 12
8 16

B.31. S59: Current Slave in Communication (default 0)

This value shows the current slave number in communication. The value is automatically stored when
the slave is selected for communication. This value can also be set by user so the master unit
connects to a specific slave to connect first in case the master unit reboots. The value range is 0~4. 0
means the maser unit never connected to a slave. The master will connect to a slave whatever
responses first.

B.32. S60: Reconnect Time Interval (default 5)

This value defines reconnect time interval in case a slave is disconnected in multiple connection mode.
The actual reconnect time interval will be the value multiplied by two in seconds. For example, if the
value is set to 5, the reconnect time interval will be 10 seconds. The value should be greater than or
equal to 5. The master unit will only try to reconnect when its mode is set to Mode1.

Appendix C: Trouble Shooting

C.1. No Data Transmission

C.1.1. COM Port Settings

Check whether the Baud rate of Parani-SD matches that of its host equipment.
Check whether the host equipment has a Data bit setting of 8. Parani-SD supports only 8 Data bit
settings. If your host equipment uses 7 Data bit and even or odd parity, it may work with a 8 Data bit
and No parity setting. This is valid only when both DCE devices are the Parani-SD. In this case, set
both Parani-SDs to 8 Data bit and No parity. If one of DCE devices is another Bluetooth device such
as Bluetooth USB dongle,7 bit data configurations will not work.
Check whether the Parity and Stop bit of Parani-SD match those of your host equipment. Parani-SD
supports No parity, Even parity and Odd parity, 1 and 2 Stop bit configurations.
Check whether the host equipment of Parani-SD uses Hardware Flow Control. Parani-SD is initially
set to Use of Hardware Flow Control. If your host equipment does not use Hardware Flow Control,
please disable the Hardware flow control option by way of the dipswitch.
Parani-SD does not support RS-232 break signal.

C.2. Data Loss or Malfunctioning

C.2.1. Hardware Flow Control

When transmitting large amounts of data with No Hardware Flow Control, Parani-SD may clear the
data buffer unexpectedly. The possibility becomes greater as the RF transmission environment
becomes worse.

C.2.2. Response Message

The messages of Parani-SD response may affect the function of host system. Set ATS10=0 not to send Parani-

SD response to host system and try again. Refer Appendix B. for details.

C.3. Transmission Delay

C.3.1. RF Processing Delay

It takes 30msec approximately for a Parani-SD to complete a data transmission to the other Bluetooth
device. This time delay cannot be reduced and may enlarge as the RF transmission environment
becomes worse. Do not use Parani-SD If your applications cannot allow for this time delay.

C.3.2. RF Transmission Environment

If there are many Bluetooth devices working in a small area and/or the RF communication distance is
too great and/or there are some obstacles affecting RF performance, the Parani-SD repeats the
transmission packet by packet due to interferences and/or low RF performance. This may lead to
increased data transmission time delays.
