Note
Connecting and disconnecting
HP-HIL
devices while some

booting a language/operating system or running an application
program.
1.
Find the
HP-HIL
cable that came with the rotary control knob.
2. Find the end of the cable that is marked with one black dot.
3. Find the
HP-HIL
connector on the rotary control knob that is marked with
one dot.
4. Plug the "one-dot" end of the cable into the "one-dot" connector on the
rotary control knob.
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. 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
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.
