Introduction
Overview
The SV831SUN, 8 Port StarView KVM switch, represents another
addition of reliable KVM switches from StarTech.com. It allows one user
to control up to 64 SUN computers with one keyboard, mouse and
monitor.
Each SUN computer is connected to the StarView by only two cables,
one for the keyboard/mouse and the other for the VGA monitor.
Automatic keyboard and mouse simulation technology ensures trouble-
free SUN computer boot-up and seamless switching among SUN
computers. Selecting a SUN computer is as easy as pressing
pushbuttons or hot key commands. Easy-to-use automatic scan ability
catches system failure early.
The SV831SUN builds on StarTech.com’s proven success with the PS/2
StarView line, including hot plug-and-play, hot configurability, reliable
switching and ease of use. This pure SUN KVM switch is the most cost-
effective solution for contemporary server room management. Now,
save space, eliminate extra costly peripherals, enhance control and
improve the manageability of your IT data center with the SV831SUN.

Cascade (Master/Slave) Configuration
You can connect a second level of one or more StarViews to
"PC 1"~”PC 8” ports of a Master unit. Cascade configuration
expands system ability allowing you to select computers connected
to the Master or Slaves. There is only one Master, which has a
mouse, a keyboard and a monitor connected to its CONSOLE port
directly operated by a user.
Once connected, StarViews automatically configure themselves to
either Master or Slave. Slaves of different StarView models can be
mixed in cascade configuration.
Figure 2: A cascade StarView configuration
Throughout this manual, Master is the StarView that has a
physical keyboard, mouse and monitor connected to its
CONSOLE port. Slave is a StarView that has its CONSOLE port
connected to a Master's “PC x” port. Slave only exists in
cascade configuration.
Change Configuration while Running
Devices (computers or StarViews) at any ‘PC x’ port can be changed
at any time after initial power up. If you change any one of the “PC
1” to “PC 8” ports connection from a computer to a Slave or vice
versa, or replace the devices of a port; the new Slave must be turned
off before it is connected to the Master. Before unplugging the cable
from a computer, you should issue a STOP-A command for that
computer, unplug the cables, re-arrange connection, plug the cables
back to the computer, issue a GO command for that computer and
resume normal operation

Hot-key commands
Hot-key command is a short keyboard sequence to select a
computer, to activate computer scan, etc. StarView interprets
keystrokes for hot-keys all the time. A hot-key sequence starts with
two left <CTRL> keystrokes followed by one or two more keystrokes.
A built-in buzzer generates a high-pitch beep for correct hot-key
command; otherwise, one low-pitch beep for error and the bad key
sequence will not be forwarded to the selected computer.
ꢂ To select a computer by hot-key command, you must know its
channel address, which is determined by the StarView connection.
For a computer connected to a Master, its address is represented by
the PC port label (1~8 or A~H). For a computer connected to a
Slave, two characters represent its address. The first character is the
channel address of the Master unit (1~8) and the second one is the
channel address of the Slave (1~8 or A~H). Please note that only
Master's 'PC 1' ~'PC 8' ports can be connected to a Slave.
Left Ctrl + left Ctrl + 7
Selects a computer connected to port 7 of the Master.
Left Ctrl + left Ctrl + 6 + 3
Selects a computer connected to port 3 of a Slave connected to port
6 of the Master.
ꢂ To start Auto Scan, automatically scan power-on computers one
by one at a fixed interval:
left Ctrl + left Ctrl + F 1
When Auto Scan detects any keyboard or mouse activity, it
suspends the scanning till activity stops; it then resumes with the next
computer in sequence. The length of the Auto Scan interval (Scan
Rate) is adjustable, see below. To abort the Auto Scan mode, press
the left Ctrl key twice.
ꢂ To adjust Scan Rate which sets the duration before switching to
the next computer in Auto Scan:
left Ctrl + left Ctrl + F3
The StarView sends one to four beeps indicating scan interval of 3, 8,
15 and 30 seconds respectively.

ꢂ Audio Stick
An optional multimedia module can be LINKed to the back of each
StarView for selecting microphone and stereo speaker signals.
There are two options for Audio Stick: ON and Off. When set to 'On',
audio selection follows computer selection. When set to 'Off', audio
selection stops following computer selection. It is useful if you want
to listen to a particular computer's audio signal while operating
other computers.
left Ctrl + left Ctrl + F5
The StarView generates 1 or 2 beeps corresponding to On and
Off respectively.
ꢂ Return to the previously selected computer
This is used to toggle back and forth between the currently selected
computer and the previously selected one. It is handy if there are two
computers of great interest requiring your attention
Left Ctrl + left Ctrl + F7
Note: If you issue an incorrect hot key command the StarView sends
out a warning with one long beep followed by a short one.
