WDT-02

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 without terminal board, cable, buzzer relay, LED, temperature sensor.

Features:

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 WDT <=> Watchdog Power failure LED display only on terminal board. IRQ:3,4,5,6,7,9,10,11,12,14,15 4 BIT TTL output: logic high:2.4Vdc min,source 400uA. logic low:0.5Vdc max,sink-10mA Two Relay for watchdog or temperature failure Contacts:FoRM c. Max switched current:1A 30V/dc Max switched voltage:120Vac/60Vdc Max carry current:1.25AC/DC Program Example: WDT-01 is assigned to LPT2(278) I/O address. means Hexcode 0d The content of Set.da files:t=4s The content of End.da files:e type Set.da>1pt2 (set the period of the watchdog timeout,and start counting) type End.da>1pt2(stop watchdog counting) Please note:If with DOS command Copy con LPT2 the DOS will sendafter press ENTER key. WDT-01 will not acceptcode.
