The CN9000/CN9600/CN9900/CN9950 needs to be
started before the KVM switch
1. If the CN9000/CN9600/CN9900/CN9950 is connected
to a KVM switch, make sure to power it on before pow-
ering on the switch.
2. If the KVM switch was started before the CN9000/
CN9600/CN9900/CN9950, reset or restart the KVM
switch.
The CN9000/CN9600/CN9900/CN9950 needs to be reset
(see Upgrade Main Firmware, page 34, point 1).
If the CN9000/CN9600/CN9900/CN9950 is behind a
router, the router's Port Forwarding (also referred to as
Virtual Server) feature must be configured. See Port
Forwarding, page 140, for details.
If you find the display of two mouse pointers (local and
remote) to be confusing or annoying, you can use the
Toggle Mouse Display function to shrink the non-
functioning pointer. See page 86 for details.
If you find the mouse pointer movement of a connected
PC/server using PS/2 control (CN9000) is not in sync with
your remote mouse operation, you can do the following:
1. On the connected PC/server, turn off "Enhance pointer
precision" in its mouse settings. If the problem persists,
go to Step 2.
2. On the web browser of the CN9000, execute terminal
command "setportatt 1 <n>" to set mouse delay time
by 'n' milliseconds. You can start with n = 10, and then
adjust as needed. See Terminal, page 44.
1. This problem may also occur on connected PC/
server using USB mouse control without
absolute coordinate support (CN9600/CN9900/
CN9950).
2. To reset the mouse delay time back to default,
execute terminal command "setportatt 1 0"
There is too much data being transferred for your
connection to keep up with. Lower the video quality (see
Video Settings, page 93) so that less video data is
transmitted.
