Watchdog Control Code

The code for controlling the watchdog/COP timer is the simplest and least-customizable of the included sample

scripts. The code itself is provided on the software DVD, under

\examples\project\WatchDog\, and the

executable file Watchdog.exe is on the software DVD

\examples\TC6000Release. This sample code may

be modified to integrate the watchdog timer with specific applications

Using this code any program may be set up so that the watchdog timer will provide a last-line failsafe against

application crashes. For instance, the TC-6110 may be set up so that whenever a mission-critical application

fails the watchdog timer will send a message to a system administrator and then initiate an automatic reboot.

To test the watchdog executable, follow the steps below.

The Watchdog Control Code Walkthrough

1. If you haven’t yet, create the folder c:\programs\examples, then copy over Watchdog.exe and run

the script.

2. The program will return

*pdwPortVal = 0x80; this means the watchdog function is enabled and counting

down. To keep the system from rebooting, the user will need to press Enter at least once every 10 seconds,

otherwise the system will automatically reboot.

3. To stop the watchdog, press q to exit the program. The watchdog timer control will return

*pdwPortVal

= 0xc0

, indicating that the watchdog timer is now disabled.

T-Sensor Control Code

The TC-6110 computer comes with built-in, independent temperature sensors that may be customized for

automated responses. The temperature sensor sample code may be found on the software DVD under

\examples\project\TempSensor\, and the executable file TempSensor.exe will be under

\examples\TC6000Release.

Follow the steps below for a walkthrough on using TempSensor.exe to return thermometer values.

The sample code for reading temperatures is included in Appendix B of this manual, under

The Temperature

Sensor Control Script.

Walkthrough for Reading Temperature Values

1. If you haven’t yet done so, create the folder c:\programs\examples then copy over

TempSensor.exe.

2. Insert the TC-6110 SATA expansion module into slot 1. Leave slot 2 empty.
