3.2. Serial Ports
The applicable settings for serial ports are as follows.
Table 3-2 The Parani-ESD Serial Port Settings
Serial Port Settings Values
Baud rate 1200, 2400, 4800, 9600, 19200, 38200, 57600, 115200, 230400
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 default settings.
3.3 Data Bit
Parani-ESD supports only 8 data bit. In the case of 7 data bit and even/odd parity, use Parani-ESD 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.
3.4 Hardware Flow Control
Parani-ESD 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-ESD 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-ESD malfunction consequently. In order to prevent this
buffer overflow, Parani-ESD works as follows.
When using hardware flow control, Parani-ESD 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-ESD 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.
