CHANNEL SELECTION
The FCC has allocated 125 MHz of spectrum in the band in which the TRACER 2210/3202 operates.
Figure 2 illustrates the bandwidth division.
Figure 2 illustrates the bandwidth division.
Figure 2. Bandwidth Division
To designate the utilization of the ISM bandwidth, there are four different channel plans, labeled A1, B1,
A2 and B2. 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 second portion or letter of the
channel plan refers to the receive and transmit oscillator frequencies in the radio. Numbering the lobes in
Figure 2 from left to right, a channel plan of A1 or B1 refers to transmitting and receiving on the first and
third lobes. Likewise a channel plan of A2 or B2 refers to the transmitting and receiving of the second and
fourth lobes of Figure 2. There are two rules for successful 3202 configuration.

1. The letter of the channel plan must be different on both ends.
2. The frequency number must match.
An A1 Radio must have a B1 Radio on the other end and a B2 Radio must have an A2 Radio on the other
end.

GROUNDING INSTRUCTIONS
The following provides grounding instruction information from the Underwriters’ Laboratory UL 1950
Standard for Safety of Information Technology Equipment Including Electrical Business Equipment, of
July 28, 1995.

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.
