Intel SBC-370 manual Connecting To An Atx Power Supply

The E2KEY.OBJ provides two library functions for you to integrate your application with the E2KEY function. The read_e2key and write_e2key libraries are written and compiled in C language. To implement them, refer to the functions below:

*/unsigned int read_e2key(unsigned int address): This function will return the

E2KEY data to a certain address. The address range is from 0 to 63. Return data is one word, 16 bits.

*/void write_e2key(unsigned int address, unsigned data): This function will write the given data to E2Key to a certain address. The address is from 0 to 63. The data value is from 0 to 0xffff.

To begin using this function, refer to the included EKEYDEMO.C code.

Note: The E2KEY function is based on the parallel port. Therefore, you should enable SBC-370's parallel port or it will not work.

CONNECTING TO AN ATX POWER SUPPLY

To Connect ATX Power Supply to the Backplanes and/or the ISBC Card

1.Disconnect the AC cord from the power supply to prevent sudden electric surge.

2.Connect the ATX power supply switch to the pin 17 (power button) and pin 19 (+5VSB) of CN7 (multi panel) on the board.

Figure 1. SBC-370 (through Power Button and +5VSB).

•To turn off the power supply, push the ATX power switch button for about four seconds.

•To turn the system on, push the button once.
