Tarang P User Manual Page 8 of 17 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
Tarang P User Manual Page 9 of 17 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’. 4.1 Interfacing with microcontroller
Tarang P User Manual Page 10 of 17 5. Table of AT Commands Tarang module expects numerical values in Hexadecimal. All AT commands used by Tarang modules are sorted by category. Tarang modules can be configured back to factory settings with a single command ‘ATGRD’. 5.1 Table of General AT Commands AT Command Description Parameter and Range Default Value GRD Restore Defaults: Module will be configured to factory settings - - GWR Write: Stores the set parameters to flash - - GER Erase: Software flash erase of the module - - GEX Exit: Exit from command mode - - NCH Channel: Read the channel number used for communication 0x00 - 0x0E - SBD Interface data rate: Read / Set the serial interface data rate for the module 0x00 - 0x07 0 - 1200 0x03 1 - 2400 2 - 4800 3 - 9600 4 - 19200 5 - 38400 6 - 57600 7 - 115200

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.

Tarang P User Manual Page 16 of 17 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.
