Advantech PPC-140, PPC-120 manual Installing the Sdram Memory Module

4.5 Installing the SDRAM Memory Module

You can install from 16 MB to 128 MB of SDRAM memory. The panel PC system provides one 168-pin DIMM (Double Inline Memory Module) socket and supports 3.3 V SDRAM with a minimum speed of 12 ns.

Note: The module can fit into the socket only one way. Pin 1 of the DIMM module must line up with the small arrowhead printed on the motherboard next to the DIMM socket.

The golden pins of the module must point down into the DIMM socket.

1.Detach and remove the rear cover and CPU cover.

2.Push the two white eject levers on each side of the DIMM outward until they are separated from the black vertical posts. (See Fig. 4-4.)

3.Insert the memory module into the socket at an angle of 90 degrees.

4.Push the two eject levers towards the vertical posts at each end of the socket until the module is upright.
