HP 98287 A Graphics Display Station Interface
a. Finel the set of eight switches labeled SW2 on the Graphics Display
Station Interface (see Figure 5-1). Switch
:~
in this group determines the
addressing mode.
b. Set switch 3 as follows:
• If you want to use the Graphics Display Station as the system console,
or if it is your only bit-mapped system display, set switch 3 to 0, as
shown in Figure 5-1(see Important! note below). This places the
Graphics Display Station at internal address $560000 (in hexadecimal).
If you have two Graphics Display Stations, only one of theln may be
set to internal addressing mode.
NOTE!
If you use internal addressing mode (switch 3
=
0), you cannot
also use a Series 300 bit-mapped display connected to an
HP 9S542/43/44/45A video card. (You can use a monitor
connected to an HP 9S546A Display Compatibility Interface,
however.)
You must remove your HP 9S542/43/44/45A video card. See
your Installation Reference manual for details.
To use both a Graphics Display Station and a Series 300
bit-mapped display, you must use external addressing lnode
(switch 3
=
1) as indicated below .
• To use the Graphics Display Station as a graphics output device only,
set switch 3 to 1, which is opposite the setting shown in Figure 5-1.
This places the Graphics Display Station at the external address (i.e.,
select code) specified in the next step.
5. Set the Graphics Display Station Select Code.
SKIP?
If this is the first (or only) Graphics Display Station you are
installing, you can skip to step 6. The select code is preset to
25 and need not be changed.
