FCC AND IC STATEMENTS
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
The CAT5 ClassWork Plus system gives the instructor control over every student’s
monitor, mouse, and keyboard in the classroom.
The CAT5 ClassWork Plus comes in two versions: an internal PCI card version and
an external box version.
This guide describes the installation of both versions.
NOTE
The two CAT5 ClassWork Plus versions are fully compatible with each
other.
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 PCs in a loop without Multiloop; Up to 63 Student PCs with
Multiloop.
• A transmission range of 360 ft. (110 m) without Multiloop; Up to 980 ft.
(299 m) with Multiloop.

CHAPTER 3: Overview
3. Overview
The basic computer equipment for the Instructor and each Student is a CPU, a
keyboard, a monitor, and a mouse.
The specialized CAT5 ClassWork Plus equipment for the Instructor Unit Kit
(AC840A-R2 or AC840AE-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 loop,
• (1) power supply,
• monitor, keyboard, and mouse cables, and
• this users’ manual.
The specialized CAT5 ClassWork Plus equipment for the Student Unit Kit
(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 loop,
• monitor, keyboard, and mouse cables (all necessary cables are included), and
• this users’ manual.
NOTE
The Student Interface Card and the Student Interface Standalone Unit
are fully compatible with each other.
The CAT5 ClassWork 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 first
student’s computer in a loop,
• (1) power supply,
• monitor, keyboard, and mouse cables for Instructor and Student units,

10
CAT5 CLASSWORK PLUS
• (3) Student Interface Cards to link one student’s computer to the next
student’s computer in a loop, and
• this users’ manual.
You can also order the Instructor and Student Unit Standalone boxes separately:
• For the CAT5 ClassWork Plus Instructor Unit, order part number AC845A
(includes monitor, keyboard, and mouse cables; power cord; power supply;
and this users’ manual).
• For the CAT5 ClassWork Plus Student Unit, order part number AC846A
(includes monitor, keyboard, and mouse cables; power cord; power supply;
and this users’ manual).
3.1 Multiloop
There are three things to consider when deciding whether to include the
Multiloop (part number AC844A or AC844AE; these are covered in a separate
manual) in your system.
• The number of CAT5 ClassWork Plus Student Interface Cards or Student
Interface Standalone Units you’ll be connecting.
• The length of the system cable.
• The screen resolutions and refresh rates.
With Multiloop, you can:
• Connect up to 63 CAT5 ClassWork Plus Student Interface Cards or Standalone
Units to the CAT5 ClassWork Plus system.
• Increase the overall system cable distance up to 980 ft. (299 m).
We recommend installing Multiloop when:
• There are more than 15 Student Interface Cards or Standalone Units.
• The overall cable length exceeds 360 ft. (110 m).
This recommendation is dependent upon the screen resolution and refresh rates
of the computers. You can still install the CAT5 ClassWork Plus system for more
than 15 Student Interface Cards or Standalone Units without the Multiloop and
still achieve acceptable screen transfer results. However, if you use high screen
resolutions and refresh rates, then consider using Multiloop.

Components
4.1 About the CAT5 ClassWork Plus
Each CAT5 ClassWork Plus system uses:
• An Instructor Control Unit (described in Chapter 9).
• An Instructor Interface Unit, which is a closed box that you connect to the
Instructor’s position (see Section 4.2).
• A Student unit, which is a PCI card (you insert it in the Student’s computer) or
a standalone unit. (See Sections 4.3 and 4.4.)
CAT5 ClassWork Plus supports up to 31 student units connected in a loop (without
Multiloop).

5. Pre-Installation Guidelines
Please note the following:
• A certified electrician should prepare sufficient electrical wall sockets. Each
outlet should have the same phase and a common ground.
• Place cables away from fluorescent lights, air conditioners, and machines that
generate electrical noise.
• All the computers must be PS/2 type.
• All mice, keyboards, and monitors must be PS/2 type.
• Make sure that the total system cable length does not exceed the transmission
distance.
• A raised floor in the classroom can significantly reduce the system cable
length.
• Run cables through a conduit in the floor or wall where available.
• Check whether Power Poles are used.
5.1 The System Cable
For the system cable, use the FTP shielded 4 x 2 x 24 AWG CAT5 or CAT5e data
cable. We strongly advise against using patch cable because of its higher resistance
and capacitance.
NOTE
Run the system cable as short as possible to ensure better screen
transfer quality.
5.2 Ground Loop Problems
Before installing the CAT5 ClassWork Plus, check for ground loop problems.
These are caused by having equipment connected to different ground points via
interconnected cables. If the difference in ground potentials (voltage) is great
enough, it can create a current sufficient to cause the problem. It can also weaken
electronic components and be a safety hazard.
CHAPTER 5: Pre-Installation Guidelines

18
CAT5 CLASSWORK PLUS
5.3 Ground Loop Solutions
• Have a qualified professional measure the AC and DC voltages between the
ground points. Ground potential differences greater than 2 volts will affect the
ClassWork Plus system.
WARNING
Risk of electric shock! Electrical measurements and modifications
should only be attempted by qualified personnel.
• The most important element in reducing ground loops is good wiring
throughout the building. Faulty wiring can be lethal, as well as hazardous to
equipment. Use full-size ground conductors to reduce the ground impedance.
Use ground grids to equalize the ground potential. Refer to the National
Electrical Code®(NEC®). The online version can be found at
http://www.necdirect.org.
• The simplest method of controlling ground loops is to connect all equipment
to the same building ground point. This is not always possible because of the
physical placement of system components and the distances between them.
• Cable routing is also important. Keep cable runs as short as possible. This will
keep cable resistance to a minimum. The less cable, the less ground loop
voltage created.
NOTE
Cables and equipment placed in close proximity to light dimmers,
motorized electronics, and electronics generating RF emissions can
create noise in the system.
• If ground loop origination points are difficult to pinpoint, connect equipment
chassis grounds using 8- or 10-gauge ground wire.
NOTE
Do not open equipment. External ground points should be present on
most equipment.
