Robust solution for connecting asynchronous RS 232 devices in an error free manner over synchronous 64 kbps leased lines. Operates in pairs.
Converts between asynchronous RS232 and synchronous V.35 interfaces; provides automatic detection and correction of data transmission errors.
1500 VAC isolation protection on RS232 Ports.
Console port for configuration and diagnostics.
Status display indicators. 230 VAC operation. Use the CYGNUS 421 ECC (JTBS Linker) to achieve error-free communication between asynchronous RS232 devices over a 64 kbps leased line. The CYGNUS 421 operates in pairs across the leased line and connects to external 64 kbps modems through a synchronous V.35 interface. It supports up to two asynchronous RS232 user devices. Isolation protection of 1500 VAC is standard for these two RS 232 ports (although the product is optionally also available without this isolation protection). The unit operates from standard 230 VAC power supply and has a built-in SMPS to ensure reliability. Configuration and diagnostics can be carried out through a console port provided for the purpose.

GSM Modem can be used for developing applications that require to sendreceive SMS in English as well as applications that require to send receive SMS in local languages (Unicode). CRR SMS Server 8 GSM Modem is a easy-to-use on Windows NTXP20002003 based bulk mobile messaging software that can be used to send SMS and WAP Push to a list of phone numbers from your PC using any GSM Modem or Phone. The list of phone numbers can be either manually entered or imported from a text file, Excel worksheet or Access database.

With our expertise in the industry, we are engaged in offering the best range of gprs modems at very affordable rates. For our buyers in Bangalore(India) and other markets, we provide a vast array of the product at competitive prices.

The project is aimed to design a system using which we can send the messages to the mobile by using PC and a GSM modem, without internet connection to the PC. GSM Modem can accept any GSM network operator SIM card and act just like a mobile phone with its own unique phone number. Advantage of using this modem will be that you can use its RS232 port to communicate and develop embedded applications. Applications like SMS Control, data transfer, remote control and logging can be developed easily. The modem can either be connected to PC serial port directly or to any microcontroller. The project is designed in such a way that the controller will be interfaced to the PC, as well as to the GSM modem through a line driver IC max232 for serial communication. Serial communication is often used either to control or to receive data from an embedded microprocessor. Serial communication is a form of I/O in which the bits of a byte being transferred appear one after the other in a timed sequence on a single wire. The front end application will be developed on C# .NET platform for the visual effects so that the application can be easily accessed. The application will be designed in such a way that it contains a text box in which we can enter the required text and as the application always interact with the serial port it sends that text to the PC serially and then the controller sends it to the GSM modem in an SMS format as per the code logic. So that the mobile with the preprogrammed number will receive that particular message through GSM modem. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.   Micro Controller : AT89S52 Crystal : 11.0592 MHz Lcd : HD44780 Gsm Modem Max232 Pc Software Requirements Keil Proteus Uc Flash C# Embedded C
