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.

Serial Port Settings Values
Baud rate 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, 230400, 460800,

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.
3.4. 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.
