CHAPTER 5: Configuration
5.2 Setting the Remote Unit’s DIP Switch
You’ll also find a four-position DIP switch labeled SW1 on the circuit board inside
the Extender’s Remote Unit. The functions of this DIP switch are different for
each Extender model. (For directions on opening and closing the Remote Unit’s
case, including the static-electricity precautions you should take, see the start of
Chapter 5.)
5.2.1 O N THE S INGLE -A CCESS (ACU1001A) M ODEL
Only position 4 of this DIP switch is meaningful; don’t change the settings of any
of the other switch positions. (Position 4 is the bottom one, or the rightmost one if
you hold the Remote Unit by its left end.) When position 4 is in its factory-default
ON setting, the Extender resets the keyboard and mouse (see Section 7.3.1) when
you press Scroll Lock. But if you need the Scroll Lock key for some other function,
you can force the Extender to pass Scroll Lock through to the PC (disabling the
reset function) by setting position 4 to OFF.
5.2.2 O N THE D UAL -A CCESS (ACU1009A) M ODEL
Each of the DIP switch’s four positions controls a configuration setting:
• Position 1: 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 is blanked while the Extender is in Private Mode (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: 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 (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. 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.
• Position 3: When position 3 (the third one from the top, or third from the left
if you hold the Remote Unit by its left end) is in its factory-default ON setting,
users have to press a key on their keyboard to take control of the Extender
system 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.
