5.3 Setting the 4-Position DIP Switch in All Non-Micro Remote Units
You’ll also find a four-position DIP switch labeled SW1 on the main circuit board
inside the full-size (non-Micro) Remote Units. The functions of this DIP switch are
different for different Extender models.
5.3.1 ACUREM
AND
ACUSREM
For ACUREM and ACUSREM, position 4 of this switch is usable in all applications,
but do
not
change the settings of positions 1 through 3 of this switch unless you are
using the Remote Unit in a Dual-Access (ACU1006DRA or ACU1006DSRA)
system. Each position controls a configuration setting that will apply to the Remote
Unit’s attached remote user station and (in Dual-Access systems) any
corresponding local user station:
•
Position 1 (Dual-Access systems only):
When position 1 (the topmost jumper,
or the leftmost if you hold the Remote Unit by its left end) is in its factory-
default OFF setting, the remote monitor attached to that Remote Unit is
blanked while the Extender is in Private Mode for the corresponding CPU (see
Section 7.3.4
), so that users at the remote station can’t see what the user at the
local station is doing. However, if you want to prevent the remote monitor
from being blanked during Private Mode—so that users at the remote station
can still see what’s going on—set position 1 to ON.
•
Position 2 (Dual-Access systems only):
When position 2 (the second one from
the top, or second from the left if you hold the Remote Unit by its left end) is
in its factory-default ON setting, the inactivity timeout for the corresponding
CPU (see
Section 7.3.3
) is set to two seconds: Once the local or remote
keyboard and mouse have been idle for two seconds, the user at the other
station can take control of the CPU. If you suspect that the system will be
switched too quickly with that setting, move position 2 to OFF to set the
timeout to 15 seconds instead.
KVM/Serial systems only:
Note that serial activity or inactivity has no effect on
the inactivity timeout; KVM switching will take place without regard for (or
effect on) serial transmissions.
•
Position 3 (Dual-Access systems only):
When position 3 (the third one from
the top) is in its factory-default ON setting, Extender users have to press a key
on their keyboard to take control of their CPU when it becomes idle; see
Section 7.3.3
. If you want users to be able to take control by typing at their
keyboard
or
by moving their mouse, move position 3 to OFF.
KVM/Serial systems only:
The remote user can send or receive serial data
while the local user is in KVM control (active or idle), but this
won’t
cause KVM
control to be switched to the remote user.
