CHAPTER 7: Operation
• In a Dual-Access non-serial or KVM/Serial Extender link with a full-size or
Micro Remote (ACU1006DRA to ACUREM, ACUMREM, or ACU1006MRA;
ACU1006DSRA to ACUSREM), press and release the [Scroll Lock] key
once at
the Remote or
twice
at the Local Unit.
• In a Single-Access non-serial Extender link with a Switching Remote Unit
(ACU1006RA or ACU1012RA to ACUREMSW) or a KVM/Serial/Audio link
(ACU1006VRA to ACUVREM, ACUWREM, or ACU1006MRVA), press and
release the hotkey, then press and release the up-arrow (number 8) key on the
keyboard’s numeric keypad (
not the number 8 on the top row of the
keyboard).
Note that the Extender will automatically reinitialize the keyboard and mouse
whenever you attach them. If a reset doesn’t help your remote keyboard or mouse,
try cycling power to the Remote.
Very few applications today make extensive or important use of the [Scroll Lock]
key. But if you are using such an application on a PC attached to a non-audio
Extender system that doesn’t include a Switching Remote Unit, you can force the
Extender to pass [Scroll Lock] through to the PC, disabling both the reset function
and Private Mode (see
Section 7.3.4 ) by setting DIP-switch position 2 for that link
on a Micro Remote to ON (see Section 5.1 ) or position 4 of DIP-switch SW1 on a
non-Micro Remote Unit to OFF (see Section 5.3.1 ).

On rare occasions, you might notice that, instead of behaving normally, your
mouse pointer is moving and jumping erratically all over the screen (and possibly
selecting things at random). This is usually a sign that the PS/2 mouse you’re using
has gotten “out of sync” with the Rackmount Extender, or that the Rackmount
Extender has gotten out of sync with the CPU’s PS/2 mouse port.
Explanation: PS/2 mice send mouse data in 3- or 4-byte packets. As long as the
CPU knows which bytes mark the start and end of each packet—which it virtually
always does as long as the mouse is directly connected to it—it can correctly
interpret the mouse signals. But when mice are disconnected and reconnected, or
when mouse signals pass through other devices on their way to the CPU, it is
sometimes possible for the CPU or the intervening devices to lose track of where
the mouse-data packets begin and end, with the result that the cursor/pointer
begins behaving bizarrely.
