Bluetooth Module - Serial Adapter from Sena Technologies replaces RS-232 Serial Cables

July 21, 2006

The Parani-SD is a Bluetooth Serial Adapter product line that is designed to replace RS-232 serial cables with wireless connectivity. Options include a Bluetooth 1.2 Protocol Stack that includes Adaptive Frequency-hopping spread spectrum (AFH), software-free configuration support via an external dip-switch, Pairing button for instant configuration of an automatic connection between two Parani-SD devices, and flexible power options.

It enables a serial device to communicate with another serial port adapter or other Bluetooth enabled devices such as mobile phones, handheld computers and laptops. The Parani-SD product line has a 9 pin female DB-9 connector, uses a stub antenna, and supports the General access and Serial port profiles. The Parani-SD100 is a Class 1 type and Parani-SD200 is a Class 2 type adapters. Both are Bluetooth 1.2 compliant devices.

Software-free configuration support
The Parani-SD series has Software-free configuration support via an external dip-switch. Using this switch, serial port parameters can be easily configured without host computer. In addition, the unit has a Pairing button that facilitates instant configuration of an automatic connection between two Parani-SD devices without a host computer. Once the
pair is established, communication between the two Parani-SD devices should be relatively seamless.

Battery pack case
The Parani-SD200 has support for a Battery pack case that can carry two AA type batteries. This facilitates the Parani-SD200 to be used in situations where power is a problem. In addition, the Parani-SD200 can be powered using a Power Adaptor, DC power cable, or USB power cable.

Bluetooth 1.2 Protocol Stack
The Parani-SD series has the strength of Bluetooth 1.2 Protocol Stack that includes Adaptive Frequency-hopping spread spectrum (AFH), which improves resistance to radio frequency interference by avoiding using crowded frequencies in the hopping sequence. In addition, the Parani-SD series probes and connects to serial devices at a faster rate.

Wireless transmit range
With no drivers required, the Parani-SD Bluetooth serial adapter is developed for long-range wireless serial communications. Transmit range can be extended up to 1 kilometer when using the optional patch antenna.

Application Areas
Supporting data transfer speeds up to 230Kbit/s, the Parani-SD Bluetooth serial adapter is suitable for industrial applications that require data logging, wireless sensor control and monitoring in production facilities. Also in medical applications, physicians with hand held devices are able to view and update medical databases and patient's charts instantly, reducing redundant paper work, increasing efficiency and lowering hospital costs.

Other applications include retail POS, bar code scanners and credit card readers, restaurant order and receipt printers, security systems, gas pumps, and outdoor sign boards.

Package
Included in the package with the Parani-SD is a stub antenna, USB power cable, DC power cable, Power adaptor, Battery pack case (for Parani-SD200) and a CD-ROM. Further, a configuration utility is included, which allows custom configuration of settings such as serial port parameters, flow control, baud rate, connectable mode, discoverable mode and security.
