3. Apply power to the board by connecting the power supply to an electrical outlet.

When the board is powered up, LED CR8 (at location H-5 in Figure 2-1 on

page 2-3) comes on for one second and then goes off. This indicates that the U

transceiver (T7237A at location H-5 in Figure 2-1 on page 2-3) has powered

up. The same thing happens when you reset the board.

If all of the LEDs are not illuminated, remove the power supply immediately

and contact AMD technical support. See “Technical Support” on page iii for

contact information.

CAUTION: If using your own power supply, be sure it is a

12V

supply and is capable of providing at least 2 A.

4. Invoke the terminal emulation program at 19200 baud, no parity, 8 data bits,

and 1 stop bit; enable the software flow control (Xon/Xoff), if supported.

5. Reset the board by depressing and releasing the RESET switch (see SW1 at

location E-9 in Figure 2-1 on page 2-3).

Type an a in the terminal window to ensure that the E86MON software uses

the correct baud rate. When the E86MON software receives an a, it adjusts its

baud rate (if necessary) and displays the welcome message and prompt.

NOTE: If you type a character other than an a, or type no character at all, the

E86MON software still displays the welcome message and prompt, but may

be using an incorrect baud rate. Depressing and releasing the RESET switch

(SW1 at location E-9) gives you another opportunity to type an a.

6. To display the version of the monitor and the commands available, type ? and

press Enter.

For detailed information about using the E86MON software, refer to the

E86MON

Software User’s Manual included in your kit.
