Configuring the Digitizers

Adding RAM to the Module

This section gives guidelines to configure the digitizers, including:

Adding RAM to the Module

Setting the Logical Address Switch

Setting the Interrupt Line

Installing the Digitizer in a Mainframe

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.

Selecting a RAM Although most commercially available PC SIMM RAM will work with the 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 Figure 1-3). 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 Figure 1-3, when purchasing your upgrade RAM .

L = 1.25in (31.77mm) max for D = 0.18, where D is from PC board lower side where it rests on the bracket. D does not include the height of chips mounted on the lower side of the board.
