HP 46087/88A Digitizers and
HP 46089A Cursor
Installation Procedure
Note
Connecting and disconnecting
HP-HIL
devices while some
language / operating systems or application programs are
running may lead to unpredictable results. When possible,
connect all needed
HP-HIL
devices to your computer before
booting a language/operating system or running an application
program.
1. Find the
HP-HIL
cable that came with the digitizer.
2. Find the end of the cable that is marked with one black dot.
3. Find the
HP-HIL
connector on the digitizer that is marked with one dot.
4. Plug the "one-dot" end of the cable into the "one-dot" connector on the
digitizer.
5. Connect the other, "two-dot" end of the cable into the
HP-HIL
connector on
your computer (marked "KYBD" or "KEYBOARD"), or to the "two-dot"
connector of the last
HP-HIL
device you installed (e.g. keyboard).
6. Plug the stylus or
HP
46089A Cursor into the round connector on the
digitizer.
7. Keep these constraints in mind:
• You cannot have Inore than 7 HP-HIL addressable devices connected to
your computer at one time. The
HP
46080A, 46081A, 46082A and 46082B
Extension modules and the
HP
46089A Four-Button Cursor do not count
as addressable devices, and the
HP
46085A Control Dials Module counts
as
three
addressable devices. All other devices count as one addressable
device.
• The current requirements of all of your devices must not exceed 750
milliamps (rnA). To make sure you do not exceed this requirement, total
up the typical power required by each of your
HP-HIL
devices as given in
the following "Worksheet Entries" sections. If the total exceeds 750 rnA,
you must remove one or more devices.
