CLASSVIEW INSTALLATION AND OPERATIONS MANUAL
GETTING STARTED
To acquaint you with your ClassView unit, this manual first describes
ClassView's front and rear panels. Installation and operation instructions
begin with the Quick setup system wiring guide. This easy-to-understand
diagram illustrates how to connect ClassView to your CPUs, monitor,
keyboard, and mouse.
Package Contents
Your Class View package includes the ClassView unit, a power transformer,
this manual, and a keyboard template. Cables are generally ordered and
shipped separately.
Cable requirements
ClassView connects to a CPU with a CPU adapter cable and to the
keyboard, monitor, and mouse with a Keyboard-Monitor-Mouse ada pter
cable. These cables are most commonly purchased with the ClassView and
will provide quick and trouble-free operation. If you wish to build your own
cables, refer to the pin out information in Appendices A, B, and C. Appendix
F Describes the cable part number based on the type of equipment you wish
to connect. Appendix F lists the most common cables.
To interconnect the units together you use coax bus cables between each
box and terminators at the first unit on the bus and the last unit on the bus.
Cables and accessories are available from where you purchased your
ClassView.
Most installations use a cable for the CPU and monitor, keyboard, and
mouse which are no longer than 20 feet in length. Cable length will affect the
quality of the video, depending upon which resolution you will be using. You
can improve the video resolution and distance by ordering coax cables for
your CPU and monitor connections, see Appendix F and G and Table 6
Video Distance Capability.
Locating the unit
The ClassView unit is best located near the CPU and associated keyboard,
monitor, and mouse. This will reduce the length of the cables and provide a
more cost-effective and neater installation. The total length of bus cable
should not exceed 200 feet, depending upon the resolution of video used.
Typically you should leave the front panel accessible in order to view the
status and send signals, though once all is installed you will probably not
need to see these LEDs.

Warning: Avoid routing cable near fluorescent lights, air
Installing the ClassView
Please refer to the safety section prior to installing ClassView. This section
provides instructions for the setup or your ClassView. For an illustrated
example, see the Quick setup system wiring guide on the previous page.
ClassView will support the monitor, keyboard, and mouse you
plan to use.
Step 1. Connecting the keyboard, monitor, and mouse
The Keyboard-Monitor-Mouse adapter cable connects your keyboard,
monitor, and mouse equipment to the ClassView. Various styles of electrical
connectors are used by different classes of equipment, so you should have
the correct cable to match your equipment's connectors. Adapter cables are
available where you purchased your ClassView. Should you prefer to build
your own cables, however, pin out information is shown in Appendices A & B.
1.1 Plug the DB-25 male connector of the adapter cable into the connector
labeled "Keyboard/Monitor/Mouse" on the ClassView front panel.
1.2 Plug the adapter cable's keyboard, monitor, and mouse connectors into
your equipment's corresponding connectors.
Step 2. Connecting the CPU
A CPU adapter cable connects your computer to the ClassView. CPU
adapter cables are available where you purchased your ClassView. Should
you prefer to build your own cable, pin out information is shown in
Appendices A and B.
2.1 Plug the DB-25 male connector of the CPU adapter cable into the
connector labeled "Computer" on the ClassView front panel.
2.2 Plug the CPU adapter cable's monitor, keyboard, and mouse connectors
into the CPU's corresponding ports.
conditioning compressors, or machines that may create electrical
noise. For best qual it y video, when exc ee di ng 20 feet use coax
cable. See Table 6 Video Distance Capability and Appendix F
and G for further cable information.
CLASSVIEW INSTALLATION AND OPERATINS MANUAL

Step 3. Connecting the bus
3.1 Connect the units together with the coax bus cables by connecting either
bus in or out to either bus in or bus out of the next unit.
3.2 Install terminators on the first unit on the bus and the last unit on the bus.
3.3 Set the dip switch address to identify the CPU numbers. The teacher's
station must be set to address 255. The students are usually set to start
with address 1, the next would be 2 and so on. See Appendix D for
further dip switch information.
Step 4. Powering up the system
4.1 Plug in the power transformer's power jack into the power plug located
on the back of the ClassView unit, then plug the transformer into a
power strip or wall outlet.
4.2 Push the On/Off switch on the back of the ClassView to power it up.
4.3 Upon power-up the yellow status light will light briefly and go out. After a
few seconds the status light will flash irregularly as it talks to the
keyboard and mouse attached. Then if other units are on the bus, the
LED will flash at a stead one second interval. Fi it flashes at a faster
rate, about 3/second, this indicates either a hardware error or a duplicate
address. See the troubleshooting section for more information.
4.4 Boot up the CPUs. ClassView emulates all keyboard and mouse
functions for automatic boot-up. You do not have to re-boot a CPU, if it
is inconvenient. In this case you may need to issue the mode command,
see page 15 to have proper keyboard communication.
Step 5. Testing the installation
Your ClassView is now ready for operation using its default settings. To take
full advantage of the ClassView features, refer to the Operation section
beginning on page 10. The Operation section gives detailed information
about each of the ClassView commands, describing its application and giving
the keyboard command sequence. For your convenience, this information is
summarized in the keyboard commands summary on page 19. To begin
switching immediately, however, use the following instructions.
5.1 Locate the keyboard template provided with the unit. Put it on the upper
function keys of your keyboard. The template has commands at the top
and station numbers at the bottom. Commands are carried out by
pressing and releasing the left control key, hitting the function key
corresponding to the command desired, and hitting another function key
corresponding to the station(s) to which the function will apply.

commands from the keyboard. You have two seconds between each
keystroke to enter a valid command, otherwise ClassView aborts the
command.
NOTE: When entering numeric commands from the keyboard, use
only the numeric keys located at the top of your keyboard. Numbers
entered from the numeric keypad on the right of the keyboard will not
be recognized as valid commands.
NOTE: ClassView commands ignore case. All command letters are
shown capitalized for clarity only. Don't use the shift key though.
NOTE: All non-switching commands which require a numeric operand
must use the [Enter] key to complete the command.
NOTE: The CPU number may be entered as a function key or as a
numeric value. The numeric value is required if there are more than
10 ports in the system.
View command
The view command is used to observe a student's screen. The command is
issued b pressing and releasing the control key, hitting the F1 key, and then
hitting a CPU number (see Note). All keyboard and mouse data will be

Share command
The share command is used to interact with a student. The command is
issued by pressing and releasing the control key, hitting the F2 key, and then
hitting a CPU number (See Note). All keyboard and mouse data is shared
according to the keyboard timeout setting. If the student is currently using
the keyboard and mouse when first switched to, the student will retain
control. After two seconds of inactivity the instructor can gain control. The
instructor will retain control until there is no keyboard or mouse activity for the
period of the keyboard timeout setting. Hitting share with an operand of ALL
(F12) will enable the scan mode. Hitting share with an operand of ME (F11)
will restore normal connection of the instructor's keyboard and mouse back
to their own CPU.
Control command
The control command is used to gain full control of a student's computer.
The command is issued by pressing and releasing the control key, hitting the
F3 key, and then hitting a CPU number (See Note). The student's keyboard
and mouse will be locked out and the instructor will have exclusive use of the
student's CPU. Hitting control with an operand of ME (F11) will restore
normal connection of the instructor's keyboard and mouse back to their
own CPU.
Show command
The show command is used to show the instructor's screen to any or all
students. The command is issued by pressing and releasing the control key,
hitting the F4 key, and then hitting a CPU number (See Note). The teacher
will retain control of their own CPU. The student's keyboard and mouse will
be locked out. Hitting show with an operand of All (F12) will send the
teacher's screen to all students. Hitting show with an operand of ME (F11)
will restore normal connection of the instructor's keyboard and mouse back
to their own CPU.
Enable command
The enable command restores any or all student's CPUs to the normal mode
of being connected to their own CPU. The command is issued by pressing
and releasing the control key, hitting the F5 key, and then hitting a CPU
number (See Note). Hitting enable with an operand of All (F12) will restore
all students' CPUs.
Disable command
The disable command blanks any or all student's screens and locks their
keyboard and mouse. The command is issued by pressing and releasing the
control key, hitting the F6 key, and then hitting a CPU number (See Note).

Freeze command
The freeze command keeps the students screen active but locks their
keyboard and mouse. The command is issued by pressing and releasing the
control key, hitting the F7 key, and then hitting a CPU number (See NOTE).
Hitting freeze with an operand of All (F12) will freeze all students' CPUs.
Hitting freeze with an operand of Me (f11) will have no effect.
Entering station numbers by numeric value
When entering a numeric value of a station number there are certain rules on
how to properly do it. After you press and release you keyboard's left control
key ([Ctrl]), and then enter the command desired, type in the port number as
described below. Remember to use the numbers located at the top of our
keyboard. Do not use the numeric keypad. The maximum scan port is also
used to determine the number of keys required to enter a port number. If the
maximum scan port is set to 99 or less, then only two digits are required to
enter the port number. If the maximum scan port is set to 100 or greater,
then three digits are required to enter the port number to select.
16 – 99 Ports: ClassView will execute the command on the desired station
when you enter the two-digit number. For single-digit ports, you can enter
the number with a leading zero (such as 01) or enter the single-digit number
and press [Enter]. If you enter only one digit, and do not follow it with
[Enter], ClassView will wait two seconds for you to enter another digit, then,
if no additional number is entered, will execute the command on the singledigit port.
100 – 256 Ports: ClassView will execute the command on the desired station
when you enter the three-digit number. For single-and-double-digit ports,
you can enter the number with one or two leading zeros (such as 027 or
001), or enter the single-or-double-digit number and press [Enter]. As noted
above, ClassView will wait two seconds for a second or third number to be
entered, then will execute the command on the port number entered.
Going to the next highest or lowest port
From the keyboard you can switch forward or backward through the CPUs by
using the + and – keys. To go to the numerically next higher port, press and
release the left control key ([Ctrl]), then press the "+ /-" (plus) key. To go to
the next numerically lower port, press and release ([Ctrl]), then press the '+/" (minus) key. The command is not case sensitive. Use the keys at the top
of your keyboard, not those on the numeric pad.
The count wraps around. If follows the ports as defined by the scan
minimum and maximum settings, described later.
12
CLASSVIEW INSTALLATION AND OPERATIONS MANUAL
Keyboard timeout command
This is a very powerful feature that controls when two or more keyboards are
sharing a CPU. The setting of this interval value determines after what
amount of time a CPU becomes available for use by another keyboard.
This value is loaded upon connecting to a CPU and when any keyboard or
mouse activity occurs. If there is no keyboard or mouse activity for this time
interval the CPU is available for connection by another port. Each ClassView
unit can have a different timeout value set. If another keyboard connects to a
CPU on a particular unit, the timeout is set by that remote keyboard and not
the local one.
If the timeout is set for zero this is an instant timeout. Two keyboards each
set for a zero timeout and connected to the same CPU will appear to both be
connected to the CPU. If the timeout is set for 255 this is an infinite timeout.
A CPU will not be released, until another port is switched to from the
keyboard with the infinite timeout or the timeout is changed.
The default setting is 2 seconds. To set another interval, press and release
the left Control Key, type "H", enter the new keyboard timeout interval (in
seconds), and press [Enter]. Remember to use the upper numeric keys, not
the numeric keypad to the right. Follow with the Keep command to save the
setting. All student stations have a timeout of 2 seconds.
Previous port command
This setting is intended to provide a convenient method to alternate between
two CPUs. You can rapidly and easily switch to the previous port that you
were on. This especially useful when you have many CPUs and entering the
multi-digit-port number can be tedious. To set another interval, press and
release the left Control Key and then press the "Backspace" key.
Scan mode commands
To enable scanning from the keyboard, press and release the left Control
Key, then type "S". ClassView will begin scanning sequentially from its
current port through the remaining ports up to the maximum scan port and
begin again at the minimum scan port. The time between switching to the
next higher port is the scan time interval (see below) and is programmable
from 1 – 15 seconds.
To stop scanning, press and release the left Control Key, then type "X".
Scanning is also disabled by entering a port selection command. You can
program the unit to start scanning upon power-up by enabling the scan mode
and issuing the keep command.
Scan time interval command
The scan time interval command sets the time, in seconds, that ClassView
will pause at each of the ports when scanning. The allowable scan time is
from 1 to 15 seconds. The default setting is 5 seconds. To set another time
interval, press and release the left Control Key, type "I", enter the new scan
time interval (in seconds), and press [Enter].
CLASSVIEW INSTALLATION AND OPERATINS MANUAL
13
Minimum / maximum scan port commands
The scan minimum and maximum port commands set the range of ports for
which scanning occurs. The default minimum port is 1, the default maximum
port is 16. To set the minimum scan port, press and release the left Control
Key, type "<", enter the new minimum scan port and press [Enter]. To set
the maximum scan port, press and release the left Control Key, type ">",
enter the new maximum scan port and press [Enter].
The maximum scan port is also used to determine the number of keys
required to enter a port number. If the maximum scan port is set to 99 or
less, then only two digits are required to enter the port number. If the
maximum scan port is set to 100 or greater, then three digits are required to
enter the port number to select.
Screen blanking command
This feature reduces the wear on your screen and provides security for your
system by blanking the screen when there has been no keyboard or mouse
activity for a specified length of time. To set the screen blank interval time,
press and release the left Control key, type "V", enter the interval time in
seconds (0 – 999), and press [Enter] (an interval time of 0 disables this
screen blank feature). Follow with the Keep command to save the new
setting in the unit's non-volatile memory.
When in the Screen Blank state, all ClassView select LEDs will be off. To
restore the video screen, press any key or move the mouse. To disable the
screen blank feature, press and release the left Control Key, type "V", enter
"0" as the interval time, and press [Enter]. Follow with the Keep command if
desired to save it.
Mode command
ClassView supports keyboard modes 1, 2, and 3. the keyboard mode is set
by commands from the CPU. Mode 2 is the most common mode and is also
the power-up state of all 101 type and PS/2 keyboards. Mode 1 is used
primarily by most models of the latest PS/2s. Mode 3 is used by certain
specialized servers.
ClassView automatically detects a CPU's keyboard mode upon CPU boot-up
and thus learns which mode the CPU uses. If the CPU has already booted
and is then connected, ClassView cannot detect the CPU's keyboard mode
and uses the setting stored in the ClassView's non-volatile memory. The
mode command can be issued to change the keyboard mode for any port
and can be saved in non-volatile memory with the Keep command. If a port
was previously set to mode 1 and you connect a mode 2 CPU to that port, it
probably will not communicate correctly and you will need to issue the mode
command.
To issue the Mode command, press and release the left Control Key, type
"M", and enter the mode number "1", "2", or "3" followed by [Enter]. Follow
with the Keep command. To change the mode on another port, you must
first switch to that port and then issue the mode command.

Typematic value command
ClassView can be configured to control the keyboard typematic rate and
delay. This setting is used to adjust the user preference of the way the
keyboard acts when holding a key down to repeat the key, such as when
moving a cursor across a line. The rate is the speed at which the keys are
sent in keys/second. The delay is the wait time in milliseconds after the key
is initially pressed, before additional keystrokes are sent. To issue the
command press and release the left Control Key, then type "A", then enter
the 1-3 digit decimal typematic value followed by {Enter]. The typematic
value is defined as shown in the below table. Use the Keep command to
save the value.
The typematic value to be used is determined by using the equation:
Typematic Value = Rate value + Delay value. Pick the desired rate in
keys/sec. (32 choices) and delay in milliseconds (4 choices) from the below
table. Add the values to the right of the desired settings. For example to use
a Rate of 16.0 keys/sec, and a 500 millisecond delay, the typematic value
would be 7 + 32 =39, so to set this value, type Ctrl A, 39 {Enter}.
Keep command
The Keep command saves the current state of the ClassView's custom
settings. These settings are scan state upon power up, scan time interval,
scan minimum and maximum ports, screen blank time interval, CPU mode,
and keyboard LED state, keyboard timeout interval, and the keyboard
typematic value. These settings are saved in non-volatile memory and
become the power-up settings. To enter the command, press and release
the left Control Key, then press "K",

Null command
This command is used to re-synchronize an out-of-sync PS/2 mouse. Such
a condition can result due to transients, spurious power-up effects, or
plugging and unplugging of cables with live equipment. The command may
need to be entered once or twice, depending if the mouse is out-of-sync by
one or two bytes. Microsoft mouse driver version 9.01 corrects this
inadequacy of previous drivers and renders this command unnecessary. At
publishing time, it is believed this mouse driver is only available for DOS and
Window. To issue the command, press and release the left Control Key,
they type "N".
Rom identification command
This command is used to identify the revision level of ClassView firmware
currently installed. Before entering this command, your currently selected
CPU should be at a command prompt, so that when the ClassView sends the
ROM revision level that the results will be displayed. To issue the command,
press and release the left Control Key, then type "I", ClassView will send
back its current firmware revision level, in the format majorlevel, minorlevel.
Reset command
This command is used to re-boot the mouse and keyboard without removing
power from the ClassView. This is most useful to reset a PS/2 mouse which
has been unplugged and plugged back in. This command is also useful to
enable mouse data to be sent to a CPU which has not enabled the mouse.
This may be the case if the ClassView was not connected or powered off
after a CPU was booted up. To issue the command, press and release the
left Control Key, then type "R". This command should not be issued to a
CPU which has a PS/2 muse connected, but no mouse driver is loaded,
since many CPUs will crash if you send them unexpected mouse data.

Video distance capability
The limitation on driving distance is usually due to the quality of the video.
The table below shows the distances, resolution, and quality of video that
can be expected. The table uses a letter which shows the cable type and a
number which refers to the quality of the video, as described below. This
table applies to the base unit without chaining. There will be some
degradation when ClassViews are chained together. Rose Electronics does
not support systems where the video quality is 1 or 2. There are further
capabilities not listed here in order to send the higher resolution video longer
distances. Please contact Rose Electronics technical support for more
details.
N – Normal cabling
C – Coax cabling
4 – Perfect or near perfect; unable to easily detect defects in screen
3 – Very acceptable; images clear, small reflections around lettering
depending upon color; if you examine the screen closely you will
find defects
2- Acceptable; slightly fuzzy images; readable text, acceptable for casual
use, but not for prolonged viewing as this will cause eye fatigue
1- Unusable; images smeared, text not easily readable

CLASSVIEW INSTALLATION AND OPERATINS MANUAL

Power interruption to the ClassView
Certain keyboards are sensitive to rapid cycling of the power. Since power to
the keyboard is provided from the ClassView, you should not interrupt power
to the ClassView for less than three seconds. The ClassView is immune to
such transients, but the keyboard may not reset correctly.
Rackmount kit
The Rackmount kit is an optional item that can be ordered at any time. Your
ClassView unit is pre-drilled to accept the rack-mounting screws. There are
two sized available, 19" x 5.25" and 24" by 5.25".
Keyboard commands
To enter a keyboard command, first press and release the left Control Key,
represented by [Ctrl]. Then enter the command followed by ay parameters
you wish to specify, for example the port number. Letter/symbol commands
are not case sensitive, and are shown in upper case for clarity only. Do not
use the shift key when entering a command. Do not use the numeric keypad
to enter any commands.
All ClassView commands use a two second time-out between characters, to
abort the command. This is a feature that restores the keyboard to normal
operation, so the keyboard is not put into a command mode which might lock
it up from normal operation. The [Ctrl] character is not passed through to the
CPU when it is pressed and released. The command characters and
command operands are absorbed by the ClassView and not sent to the CPU.
All non-switching commands which require a numeric operand must use the
[Enter] key to complete the command.
Refer to Table 7 for a complete list of all available keyboard commands.

c. Cable is defective, try using cable from another CPU. If problem goes
away cable is defective
d. Port on ClassView is defective, try using another port on ClassView.
If problem goes away port is defective
e. Port on CPU is defective, try plugging in keyboard or mouse directly
if problem remains CPU port is defective. If CPU power status LED
not lit, fuse on motherboard ma be blown
2. Mouse drives does not load
a. If PS/2 type mouse, CPU must be connected to ClassView or mouse
at boo-up time in order for muse to be recognized by CPU. Reboot
computer with ClassView powered on and cable attached
b. If RS-232 type mouse, make sure right COM port is being used and
syntax of mouse driver is correct to search for the correct port
c. Incompatible or old mouse driver being used, try latest driver. At
time of this publishing Microsoft 9.01 driver is best one available
3. Can't switch ports from keyboard
a. Power to ClassView was removed for less than three seconds
possibly causing keyboard to lock up. Disconnect keyboard and plug
it back in
b. The mode of the keyboard does not match that of the CPU. Issue
the mode command, usually 1 for IBM PS/2's and 2 for all others.
The default setting of the ClassView is mode 2. Sometimes an
incorrect mode will confuse the CPU or keyboard and require re-
booting the CPU or resetting the keyboard by unplugging and
plugging it back in
c. If try to reach a remote port, that port is busy. Try again later
d. If trying to reach a remote port, the bus cable is disconnected, or the
remote box is powered off. Check status LED on local unit, if it is not
flashing at a one-second interval then bus cable has been
disconnected or no other units are attached to the network. Check
remote unit for activity also.
e. KB port or CPU port cable disconnected. Typing in characters to the
KB should cause the status LED to flash more rapidly. Use this to
test if you have a good KB or mouse connection to the unit

POSITION
DIP SWITCH
VALUE
A Unit's address is determined from the settings of the dip switch upon power
up. The dip switch forms a standard binary number with up being a "one"
and down being a "zero". Each position has a value corresponding to it.
From left to right the values are 128, 64, 32, 16, 8, 4, 2, and 1. When the dip
switch is up add the values of the position to form the address value.
The most common values and positions are:
1 (8 up – shown above)
2 (7 up)
3 (7, 8 up)
