4. CHANNEL SELECTION
The FCC has allocated 100 MHz of spectrum in the band in which the TRACER 4205 operates. Figure 1
illustrates the bandwidth division.
Figure 1. Bandwidth Division
To designate the utilization of the ISM bandwidth, there are two different channel plans, labeled A and B.
The letter of each channel plan setting is preset by the factory and refers to the physical configuration of
the diplexer filter inside the environmental housing. The transmitter at one end of the link will transmit in
the lower portion of the spectrum and receive in the upper portion. Consequently, the receiver at the other
end should receive in the lower portion and transmit in the upper portion. There is one rule for successful
TRACER 4205 configuration.
1. The letter of the channel plan must be different on both ends. Shipment of a link will consist of one
Plan A and Plan B unit.
5. GROUNDING INSTRUCTIONS
The following provides grounding instruction information from the Underwriters’ Laboratory UL 60950
Standard for Safety of Information Technology Equipment Including Electrical Business Equipment, of
December, 2000.
An equipment grounding conductor that is not smaller in size than the ungrounded branch-circuit supply
conductors is to be installed as part of the circuit that supplies the product or system. Bare, covered, or
insulated grounding conductors are acceptable. Individually covered or insulated equipment grounding
conductors shall have a continuous outer finish that is either green, or green with one or more yellow
stripes. The equipment grounding conductor is to be connected to ground at the service equipment.
The attachment-plug receptacles in the vicinity of the product or system are all to be of a grounding type,
and the equipment grounding conductors serving these receptacles are to be connected to earth ground at
the service equipment.
A supplementary equipment grounding conductor shall be installed between the product or system and
ground that is in addition to the equipment grounding conductor in the power supply cord.
A
5747 MHz
B
5827 MHz
Channel Plan describes which lobe is transmitted upon.
Example: A will transmit at A lobe and receive at B.
