pin connector on the back of the M400 Keyboard. The Keyboard Control Board will need to be replaced with KBCNTRL2
020829. The older KBCNTRL2 981202 will not work correctly with the Aaeon PCM-6893.
11. After all cables are installed you will carefully need to route all the cables so that they do not obstruct the CPU7. The
LCD cable can be routed by the fan as shown in Picture 2. Extra care must be taken with the ATX power connector so
that is does not interfere with the bottom of the CPU7 card. A picture of an Aaeon installed in an M400, with the cables
routed as suggested can be seen in picture 3.
12. If the M400 was not fitted with an ATX style power supply, then you will have to drill new mounting holes for the new
ATX power supply. When you mount it be sure that it will not obstruct any fans or vents on the back, and that the back
panel will mount up squarely.
13. Use the 3/4" standoffs instead of the 1" standoffs on the side of the motherboard closest to the bottom of the console.
Then mount the bracket and fan on these standoffs with the fan pointing down towards the front panel of the console.
Now place a set of 1/16" spacers on top of the bracket and secure the bracket by installing the ¼" standoffs. (See Picture
2)
14. Re-install the CPU7; you may need to use 1/16" spacers on the top and bottom of the 1" standoffs used at the
topside of the motherboard.
15. After powering on the M400, you may need to go into the CMOS setup to change some settings. To do this, hit the
DEL key on the keyboard when the control does the Memory check. Go into STANDARD CMOS SETUP. Change the
Screen Resolution to 640x480 TT1. You must change the HALT option to ALL, BUT KEYBOARD. Go in to the Power
Management Setup and change PWRON after PWR-Fail to ON.
Note: If the motherboard was not setup at Centroid you may need to momentarily jumper pins 1 & 2 on CN9 while power
is applied to the motherboard. The motherboard will turn on and allow you to enter the BIOS. You must change the
power management as described above.
