FCC STATEMENT
FEDERAL COMMUNICATIONS COMMISSION
AND
INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio frequency energy and if not
installed and used properly, that is, in strict accordance with the manufacturer’s
instructions, may cause interference to radio communication. It has been tested
and found to comply with the limits for a Class A computing device in accordance
with the specifications in Subpart J of Part 15 of FCC rules, which are designed to
provide reasonable protection against such interference when the equipment is
operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct
the interference.
Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from d
igital apparatus set out in the Radio Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le
brouillage radioélectrique publié par Industrie Canada.

CAT5 CLASSWORK PLUS
2. Introduction
CAT5 ClassWork Plus uses UTP (Unshielded Twisted Pair) technology.
Replacing the cumbersome coaxial cable with the more aesthetic and thin
single 4-pair 100 BASE-T4 CAT5 UTP cable saves valuable resources—including
time and money.
Using coaxial cabling often meant allowing for extra cabling inside the plastic
duct installed around doorway frames and classroom walls.
With CAT5 ClassWork Plus, you can:
• Use the standard preset network cables commonly arranged in new buildings.
• Prevent hazardous and untidy cable-clutter in the classroom.
• Purchase the exact quantity of Student units for the number of Student
positions that you require, with the opportunity to add new Student units at
your convenience.
CAT5 ClassWork Plus supports:
• IBM compatible computers with PS/2 style keyboard and mouse connectors.
• VGA, SVGA, or XGA video standards.
• Up to 31 Student units in a loop.
• A transmission range of at least 360 ft. (110 m).

CHAPTER 3: Overview
3. Overview
This chapter discusses configuring the CAT5 ClassWork Plus classroom which
involves combining both:
• Basic computer equipment, and
• Specialized ClassWork equipment
The basic computer equipment for the Instructor and each Student is a computer,
a keyboard, a screen, and a mouse, and whatever else is installed
in the computer.
The specialized CAT5 ClassWork Plus equipment for the Instructor Unit Kit
(AC840A-R2) includes:
• (1) keypad/LCD control unit and control cable,
• (1) Instructor Interface Unit that links the instructor’s computer to the first
student’s computer in a daisychain,
• (1) power supply,
• Monitor, keyboard, and mouse cables, and
• this users’ manual.
The specialized CAT5 ClassWork Plus equipment for the Student Unit Card
(AC841C-R2) or Student Interface Standalone Unit (AC841A) includes:
• (1) Student Interface Card or Student Interface Standalone Unit to link
one student’s computer to the next student’s computer in a daisychain,
• Monitor, keyboard, and mouse cables (all necessary cables are included), and
• this users’ manual.
The CAT5 Classworks Plus Starter Kit (AC842A or AC842AE) includes:
• (1) keypad/LCD control unit and control cable,
• (1) Instructor Interface Unit that links the instructor’s computer to the
student’s computer in a daisychain,
• (1) power suppply,

10
CAT5 CLASSWORK PLUS
• Monitor, keyboard, and mouse cables for instructor units,
• (3) Student Interface Cards to link one student’s computer to the next
student’s computer in a daisychain,
• Monitor, keyboard, and mouse cables for student units (all necessary cables
are included), and
• this users’ manual.
3.1 Advance Planning
Thorough planning is the key to successful configuration of your CAT5 ClassWork
Plus classroom. Time spent prior to the actual installation—in preparation and
planning—will prove itself time well invested. You should draw a sketch of your
proposed CAT5 ClassWork Plus classroom taking into account the positioning of
the computers and the Instructor’s position.
Make provision for electrical wall sockets—if necessary, a certified electrician
should prepare enough outlets before you install the CAT5 ClassWork Plus
classroom. Each outlet should have the same phase and a common ground.
3.2 The Stages of the Installation
The order in which you install your CAT5 ClassWork Plus classroom is a question
of common sense and convenience. Every person has his or her way of doing the
same thing. Nevertheless, we do recommend the following guidelines:
• Before the day of the actual installation, check the classroom’s layout: the
positioning of the furniture, the lighting and electrical outlets. This will allow
time for the classroom’s administrators to carry out any rearrangements before
the day of the actual installation.
• On the day of the actual installation, the first stage is to ensure that the basic
computer equipment is installed and operates correctly. To do this, switch on
all the computers to confirm that each workstation functions. Once you’ve
tested them, switch off all the computers.
• Determine where in the classroom you are going to place the Instructor
Position. Usually the Instructor sits at the front of the class, but not always.
•Figure 3-1 illustrates the CAT5 ClassWork Plus configuration in a block
diagram.

Control Unit), see Chapter 8.
4.1 About the CAT5 ClassWork Plus
Each CAT5 ClassWork Plus system uses:
• A Instructor Control Unit (described in Chapter 8).
• An Instructor Interface Unit, which is a closed box that you connect to the
Instructor’s position (as Section 7.2 describes), and
• A Student unit, which is a PCI card that you insert in each of the Student
computers (as Chapter 5 describes).
CAT5 ClassWork Plus supports up to 31 student units connected in a loop.

CHAPTER 5: Installing the Student Units
5. Installing the Student Cards
This chapter deals with installing the Student Units. This involves:
• Opening up each of the Student computers and inserting each Student unit
card in place.
NOTE
You connect the Instructor Interface Unit to the CAT5 ClassWork Plus
system. Section 6.2 describes how to connect the Instructor Interface
Unit.
Before installing CAT5 ClassWork Plus:
• Switch off all the computers.
• Disconnect the power cord from the computer.
• Beware of any sharp edges that may be present inside your computer.
5.1 Setting the Student Number
1. Switch on all the classroom’s computers.
2. Press the PRINT ALL key on the Instructor Control Unit.
3. Press the Shift key twice on the Student keyboard (within 2 seconds). A
temporary loss of mouse control occurs.
4. Press the F1 key on the keyboard.
5. Type the three digits for that Student position (for example, 007 for Student
position #7).
6. Press the Esc key on the keyboard. This saves the ID number and exits.
7. Test the hotkey functions by pressing the keys on the Instructor Control Unit
in this sequence:
<From><*><Mastr><Enter>
* represents that Student ID number in two-digit format (for example, 07 for
Student position #7).
8. Repeat steps 2–7 to set the Student ID number for each of the other Student
positions separately.

18
CAT5 CLASSWORK PLUS
9. Disable the PRINT ALL function on the Instructor Control Unit by typing
<PRINT>.
NOTE
1. Enter a leading zero where necessary. For example, type 011 for
eleven.
2. Set each Student ID number from that Student position.
3. Each Student position requires its own unique ID number.
Before installing each Student unit, set the ID Number on each Student unit as
follows:
