2. Tarang-P series

Tarang-P series modules are designed with low to medium transmit power and for high reliability wireless networks. The modules require minimal power and provide reliable delivery of data between devices. The interfaces provided with the module help to directly fit into many industrial applications. The modules operate within the ISM 2.4-2.4835 GHz frequency band with IEEE 802.15.4 baseband.

2.1 Features

• ZigBee

• Direct Sequence Spread Spectrum.

• RF Data rate: 250 kbps.

Pro Complaint platform.

4. Interface

The Tarang modules interface to a host device through a logic-level asynchronous serial port. Through its serial port, the module can communicate with any logic and voltage compatible UART or through a level translator to any serial device (For example: RS-232 or USB interface board). Tarang can be interface with a micro controller or a PC using serial port with the help of appropriate level conversion.

Tarang supports serial data with,

• Flow Control : None

• Parity : None

• Baud Rates : 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200

• Data Bits : 8

To establish a successful serial communication with the module, serial parameters need to be configured properly in the module and host side. Both the module and PC settings can be viewed and set using AT command set through popular terminal applications like ‘HyperTerminal’.

6.2 To Hardware Erase of the module

1. Connect the pad below the pin 11 (on the shield side) of the module to 3.3V (preferably on the LM117 output).

2. Plug the module into the interface board and power it ON for few seconds. The RX LED on the interface board should light ON continuously.

3. Power OFF the module.

4. Remove the wire connection between the pad and the 3.3v source. The module is now ready to be loaded with new code.

7. Placement Guidelines

For obtaining the best possible range, the following guidelines must be adhered to while using Tarang modules.

1. It is important to ensure that the antennas (chip or wire) on the modules “see” open space

around them. Hence the modules must be mounted in such a way that there are no blocking obstacles immediately next to the antennas. The modules must never be put inside a metallic enclosure unless an external antenna is being connected to the module. The modules must not be placed too close to a wall, table or metallic surfaces.

2. The modules must be placed as high as possible from the ground.

3. Polarization of the antennas must be the same at both sides of the link. For modules with chip

antennas, the mounting should be such that the axes of the modules are parallel to each other. For wire antenna modules, the modules must be mounted such that the wires are parallel.

4. As far as possible, obstacles should be avoided in the communication path between the

modules. Metallic objects and concrete walls produce a lot of attenuation and these must be avoided to the extent possible.
