TeleServ Communication with computer via COM port Small LCD and 4 buttons
TeleServ® - is a hardware-software device that realizes an RS232-terminal that allows to communicate via COM-port with computer. There are 4 buttons and 16x2 LCD (16 chars, 2 lines) in the controller to communicate with user software and to have dialog with the user. As well the controller includes a WatchDog to supervise the computer; controller provides temperature monitoring, voltages monitoring and fans revolution control. The controller uses pre-charted matrix to make slide control of fans. Fans revolution varies depending on measured temperature of airflow according to matrix response (without external control). The controller assures early diagnostic of fans failures, prolongs fans service life period, diminishes power consuption and fan-made noise and increases reliability of hardware functioning due to the total monitoring of cooling system and signalling in case of failures. The use of controller combined with the system with redundant cooling facilities allows to create fault-tolerant system with long-life performance.The controller also emulates power on/off button and «reset» button for computer. These buttons are protected by PIN-code to prevent a unauthorized access to computer control. You can set IP address, netmask, gateway address, shutdown the computer, readout statistics, basically anything you want because most of the logic is implemented with a Perl script and it can be changed easily.

Remote monitoring

Example of using of remote monitoring with web interface. Information about current values of fan rotation speed, values of voltage and temperature of remote host could be obtained in your computer browser window. To get it, both web server and script monitoring.cgi that provides such service should be installed and run   detailed info>>

WatchDog timer

Example of using of WatchDog timer. The WatchDog timer is designed to overpass a computer hanging up. Script watchdog.cgi is created to learn the WatchDog timer facilities in interactive mode. This script is CGI program with web interface and you can use it for remote host as well    detailed info>>
