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
digital apparatus set out in the Radio Interference Regulation of the Canadian
Department of Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les

the ClassWork Junior cards
Prior to installing the card:
• Switch off all computers.
• Disconnect all power cords.
• In order to avoid electrostatic damage to the card; discharge any static electricity
you may be carrying. You can do this by touching any grounded object.
To install the Supervisor and Remote cards:
1. Remove computer covers.
2. Insert the Supervisor card into any available PCI slot of the designated Supervisor
computer.
3. Insert the Remote cards into any available PCI slot of the other computers.
4. Replace computer covers.

3. Connecting the ClassWork Junior
system
Before connecting the system:
• Switch off all computers, and disconnect the power cords
• Place cables away from fluorescent lights, air conditioners, and machines that are
likely to generate electrical noise
• Ensure that the total cable length between the ClassWork Junior Supervisor and the
last Remote does not exceed 110m / 360ft
• Caution: For continued protection against risk of fire, replace with the same type
and rating of fuse only.

2. Connect connector #(2) to the monitor’s connector.
3. Connect connector #(3) to the computer’s Screen port.
3.4 The Supervisor PCI card Power supply
The Supervisor PCI card draws its power via the computer’s motherboard.
3.5 Connecting the ClassWork Junior system
Connect the ClassWork Junior system using Shielded CAT5 FTP System cable. The
Shielded CAT5 FTP System cable consists of a Shielded CAT5 FTP (Foil Shielded
Twisted Pair) Solid Wire 2x4x24 AWG (America Wire Gauge) cable terminated with
RJ-45M connectors.
Recommendation. Before installing the Shielded CAT5 FTP System cable, work out
how to connect all the computers using the shortest possible length of cable. A shorter
cable length increases video quality, and reduces noise.
Note
If the supplied Shielded CAT5 FTP System cable length is not appropriate for your configuration, a
custom length cable can be substituted. If you choose to use a cable with a different length, make
sure to use CAT5 FTP (Foil Shielded Twisted Pair) Solid Wire 2x4x24 AWG cable.
To connect the Shielded CAT5 FTP System cable to the ClassWork Junior Supervisor:
1.Connect one connector to the ClassWork Junior Supervisor’s System Out port.
2.Connect the other connector to a ClassWork Junior Remote’s System In port.
Connect the cables to the ClassWork Junior Supervisor card as illustrated in the figure
below.
