LAN Enable/Disable

Change the setting of jumper JPL1 or JPL2 to enable or disable the onboard Ethernet (RJ45) ports LAN1 and LAN2, respectively. See the table on the right for jumper settings. The default setting is enabled

Watch Dog Enable/Disable

JWD controls the Watch Dog function. Watch Dog is a system monitor that can reboot the system when a software application is “hung up”. Pins 1-2 will cause WD to reset the system if an application is hung up. Pins 2-3 will generate a non-maskable interrupt sig- nal for the application that is hung up. See the table on the right for jumper settings. Watch Dog must also be en- abled in BIOS.

Note: When enabled, the user needs to write their own application software to disable the Watch Dog Timer.
