Adding RAM to the
Module
RAM Install Procedure
12 Digitizer Module Set-up
You can increase the size of RAM on your Digitizer module by purchasing
PC SIMM memory and installing it on the module after you remove the
standard 4 Mbyte SIMM shipped with your digitizer. Both FPM (Fast Page
Mode) and EDO (Extended Data Out) are supported.
Note
Although most commercially available PC SIMM RAM will work with
your Digitizer, there are some that are physically too large and will make
contact with the top shield when installed. A standard 72 SIMM specifies
the length (L) or keying but does not specify the depth (D). Certain depths
are too large and not compatible. The E1563/E1564 has about 17.6 mm of
space from the bottom of the SIMM RAM inserted in the socket to the top
module shield (see diagram below). You must verify that the SIMM RAM
you purchase for replacement on the module has a depth (D) that will clear
the top module shield. You can use the 4 Mbyte SIMM RAM you remove
as a guide, as well as the dimensions in the diagram below, when
purchasing your upgrade RAM .
1. Disconnect any field wiring from the module and remove power
from the mainframe before proceeding.
2. Remove the module from the mainframe and remove the top
shield from the module.
3. Remove the 4 Mbyte SIMM from the PC board by first spreading
the tabs at the ends of the SIMM connector. Store this SIMM in
an anti-static bag and save this part.
Note
It is important that you retain the 4 Mbyte SIMM you remove from the
Digitizer. If you return your Digitizer to Hewlett-Packard for repair or
exchange, you must return it in the same configuration as it was shipped to
you. You must remove your large memory SIMM and replace it with the
standard 4 Mbyte SIMM shipped with the product.
4. Add your replacement SIMM to the module's RAM socket.
5. Reinstall the module's top shield.
6. Note the new memory configuration by checking the appropriate
