•Watchdog Code examples – Ampro has provided source code examples on the CoreModule 420 Doc & SW CD-ROM illustrating how to control the WDT. The code examples can be easily copied to your development environment to compile and test the examples, or make any desired changes before compiling. Refer to the WDT Readme file in the Miscellaneous Source Code Examples subdirectory, under the Support Software menu on the CoreModule 420 Doc & SW CD-ROM.

Power Interface (J7)

The CoreModule 420 requires one +5 volt power source and uses a 10-pin header with 0.1” spacing. When the +5 power drops below ~4.0V, a low voltage reset triggers activating a system interrupt.

The power input connector (J7) supplies the following voltage directly to the module:

•5.0VDC +/- 5% @ 1.35 Amps

Table 3-19 gives the signals for Power supply pin outs.

Table 3-19. Power Interface Pins/Signals (J7)

Pin	Signal	Descriptions
1	GND	Ground
2	+5V	+5 Volts
3	Key/GND	Key Pin on connector/Grounded on board
4	+12V	+12 volts routed to PC/104
5	GND	Ground
6	NC	Not connected
7	GND	Ground
