HP 46081 A Speaker Module
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. Select a suitable mounting location for the Speaker Module. Remove the
paper backing from the back of the fastener pad. Place the pad at the
location and press down firmly for a few seconds. Attach the Speaker
Module to the fastener pad.
2. Turn the computer off and check whether there is an existing HP-HIL cable
connected to the "KYBD" (or "KEYBOARD") connector on the back of the
computer. If so, disconnect it.
3. Find the end of the HP-HIL cable that is marked with one black dot.
4. Find the connector on the back of the Speaker Module that is marked with
one dot.
5. Plug the "one-dot" end of the cable into the "one-dot" connector on the
Speaker Module.
6. Connect the other, "two-dot" end of the cable into the HP -HIL connector on
your computer (marked "KYBD" or "KEYBOARD").
7. Plug either end of the furnished audio cable into the audio jack on the
Speaker Module. Plug the other end of the audio cable into the audio jack
near the HP-HIL connector on your computer.
S. If you disconnected an HP-HIL device from the computer in step 2,
reconnect it to the "two-dot" jack on the speaker module.
9. Keep these constraints in mind:
• You cannot have more than 7 HP-HIL addressable devices connected to
your computer at one time. The HP 460S0A, 460S1A, 460S2A and 460S2B
Extension modules and the HP 460S9A Four-Button Cursor do not count
as addressable devices, and the HP 460S5A Control Dials Module counts
