TB191 Rev1 Installing An Aaeon PCM 6893 In An M400
Overview
This document describes the procedure for installing the Aaeon PCM 6893 motherboard in an M400 console This
motherboard is a replacement in systems that have an industrial motherboard and an NEC 10 4ΓΓ―ΒΏΒ½ LCD screen If you
have an NEC 9 4" Color LCD screen you will need a different LCD cable Below you will find a list of all the components
that you should have received with the Aaeon motherboard
* Aaeon PCM 6893 Motherboard complete with CPU and memory
* Heat sink fan w/ mounting bracket and 2 sets of ΓΓΒΎΓΓ―ΒΏΒ½ and ΓΓΒΌΓΓ―ΒΏΒ½ standoffs
* LCD Cable
* ATX Power Supply
* Aaeon Hard Drive cable and Floppy cable
* Aaeon Keyboard and mouse cables
* Serial and Parallel cables
* Ethernet Cable
* Misc power extension cables
* SSHDD with Linux installed
* Aaeon PS/2 to M400 keyboard adaptor cable
* Fan/inverter cable
* LCD Cable Mounting Plate
* USB cable with 1 USB extension
* KBCNTRL2 020829
Installation
The first step in the installation process is to remove all of the old components You must remove the old motherboard
assembly complete with CPU memory and heatsink You must also remove the old LCD descrambler card and LCD
cable You will no longer need the existing Ethernet cable keyboard/mouse cable or hard drive cable and floppy cable
If the power supply is not of the ATX type or a Morex PS then you will also need to remove it This document contains
the recommended installation procedure Follow it exactly to avoid any problems If there is any confusion over any of the
instructions please refer to picture 1 pic 1 shows each of the cables and their labels Picture 2 shows proper
installation of fan and bracket and picture 3 shows an Aaeon installed in M400 console
1 Install the Aaeon motherboard in the M400 on the existing motherboard standoffs The standoffs must be 1ΓΓ―ΒΏΒ½ or the fan
assembly will not install correctly
2 Attach the new LCD Cable to CN3 on the motherboard and the other end to the LCD screen using the existing screws
standoffs and LCD Cable Mounting Bracket The cable is keyed so it can only be plugged in one way The mounting
bracket goes over the LCD Connector to hold in place on the LCD
3 Attach the Hard Drive cable to IDE1 on the motherboard and the other end to the new flash card reader This cable
should be keyed If not the red stripe goes to Pin 1 which is towards the CPU Socket Note If using the flash card reader
supplied by Centroid verify JP4 has the two pins closest to the IDE connector jumpered
4 Attach the floppy drive cable to FDC1 on the motherboard pin one closest to the standoff and the other end to the
floppy drive
5 Attach the serial cable to CN6 on the motherboard This socket is keyed and can only go on one way
6 Attach the LPT1 cable to LPT1 on the motherboard This socket is keyed and can only go one way
7 Attach the USB cable to USB2 on the motherboard Pin 1 is labeled with an arrow and is the Red wire on the USB
cable
8 Connect new Ethernet cable to LAN1 on the motherboard
9 Plug ATX power connector into PWR1 It will only plug in one way
10 Connect the new keyboard/mouse cable to CN7 It will only connect one way The keyboard cable plugs into the 4
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 3/4ΓΓ―ΒΏΒ½ standoffs instead of the 1ΓΓ―ΒΏΒ½ 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 1/16ΓΓ―ΒΏΒ½ spacers on top of the bracket and secure the bracket by installing the ΓΓΒΌΓΓ―ΒΏΒ½ standoffs See Picture
2
14 Re install the CPU7; you may need to use 1/16ΓΓ―ΒΏΒ½ spacers on the top and bottom of the 1ΓΓ―ΒΏΒ½ 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

Notes
* Check that the CPU7 has enough clearance above all the cables on the motherboard especially the ATX power cable
* If the CPU7 is not inserted all the way into the socket on the motherboard then you may get a 64180 Timeout not
responding error message
