WDT-01 CR信息

产品详细说明:

The WDT-01/WDT-02 are watchdog card that provides watchdog timer, temperature monitor and power monitor functions. It also provides many signals and mechanism such as relay control, reset signal, power-good signal that allow the user to control their system as soon as the errors are occurred. There are also many signals, such as IRQ, I/O status RS-232, LED, Buzzer, will tell the user or operator that some errors are occurred. Once the WDT-01 has been power on, it will monitor the power and the temperature of PC automatically. After the software enable the watchdog timer, the WDT-01 will monitor the operations of software and hardware in the most inexpensive cost with the excellent protections. The WDT-02 is an economical version of WDT-01.Refer to the following comparison table. back •Toolkit for Windows DOS •Toolkit for Windows 95/98 •Toolkit for Windows NT •Toolkit for Windows 2000/XP •Driver for LINUX back •Watchdog Timer:Software programmable from 0.01 second to 167772.15 seconds. •Temperature Monitor:Temperature:0°C-75°C;Precision:+-1°C;onbord 2 digital LED display; Warming temperature Setting:50°C,60°C,70°C or none. •Computer Power Monitor:PC Power +5V,External Power +12V •Transmit Message Includes: watchdog timer state,Temperature status,Current Temperature scale, External & PC power status...etc. •Power Required:1.External power:+12V,3W or 2.Internal power:+12V,3W •Printer-like I/O Interface:LPT0(3bch),LPT1(378h),LPT(278h)or User Define, only need 3 I/O ports •Output Signals:Signal/Function WDT timeout Over Temperature Power failure Reset Yes No No IRQ Yes Yes No I/O status Yes Yes Yes RELAY Yes Yes No　 TTL Yes Yes No LED Yes Yes Yes RS232 Yes Yes Yes Buzzer Yes Yes Yes •WDT <=> Watchdog Power failure LED display only on terminal board.
