Application overview

TS-7200 Designed and developed by Tecnologic System (TS). ARM9 based CPU.(200 MHz) PC/104 expansion slot. Serial Interface. Ethernet Interface. USB Interface. Digital IO’s Debian Linux is an OS(Operating System) runs on compact flash card and provides some additional features more than TSLinux kernel. TSLinux is a basic version of Linux for this embedded system. TS affirm that this basic Linux makes the system RTOS(Real Time Operating System)… ??? Software development process is mostly performed on any other Linux version. In this application RHEL(RetHat Enterprise Linux) have been used for software development for embedded side.

LANTRONIX XPort® Minimal engineering effort required to web-enable virtually any electronic device. Remote command and control of edge devices. Real-time edge device status via e-mail alerts. 256-bit AES encryption for secure communications. EMC/EMI-compliant; RoHS-compliant. Everything you need — all in a single RJ45 package. Management: SNMP, Telnet, serial, internal web server, and Microsoft Windows®-based utility for configuration. Security: Password protection, Optional 256-bit AES Rijndael encryption.

Benefits & used areas of application Accessing any router through its serial port interface.. Accessing any digitizer through its serial port interface..

Development Stages As mentioned before, PC basis Linux version can be used for software development on this platform. … And you can also use Microsoft Windows based Linux emulators such as WinArm…

Multi-Threading

Multi-Threading

Summary Serial2Ethernet or Ethernet2Serial converters are used frequently in many different application. Converters made easy to control devices from remote control areas. Real time applications requires two or more thread for processing I/O data. Multithreading supplies this features to many real time software project. In this application, embedded system based converter has been implemented on TS7200 platform. This platform is too complex for this application. But source code is compatible with Linux kernel. So this system can be moved to any other platform at any time..
