Wireless Communications
The Scanner 3100 wireless communications option includes a factory-installed wireless radio module and an explosion-
proof coupler (Figure 1.8) that enables an external antenna to be safely used in a hazardous area.
Explosion-proof Coupler
An explosion-proof coupler is factory-installed in the top left conduit opening of the Scanner 3100 enclosure and the
coupler cable is factory-connected to the radio module inside the Scanner 3100. The coupler is rated for compliance with
CSA (North America) or ATEX certication requirements. See Table 7.2—Wireless Components, page 88 for replace-
ment part numbers.
Direct-Mount Antenna
The Cameron-supplied right-angle antenna (Figure 1.8) connects directly to the threaded coupler connection. When in-
stalling the antenna, ensure that it is in a vertical position well above ground level and positioned away from large struc-
tures that could interfere with signal transmission and reception.
Cameron’s direct-mount antenna is rated for a maximum of 1 watt of power and a maximum antenna gain of 10 dB (in
North America) and has a frequency range of 2.35 to 2.50 GHz. Antennas with equivalent ratings may also be used with
the coupler.

Remote-Mount Antenna
In locations where a physical barrier restricts the use of a direct-mount antenna or where a longer transmission distance
is required, a remote-mount antenna (Figure 1.9, page 14) may be installed up to 30 ft (10 m) away and connected by
cable to the antenna coupler. A remote-mount antenna and connecting cable may be purchased from Cameron (see Sec-
tion 7—Scanner 3100 Parts, page 87). If purchasing cable elsewhere, verify that the cable meets the maximum capaci-
tance and inductance ratings (Figure 2.5, page 32) and that the cable length is adequate to connect to both the antenna
and the coupler. See Specications, page 15 for additional details.
The installation of the antenna coupler, antennas, and antenna cable must meet the requirements shown in Figure 2.4 and
Figure 2.5, page 32. For installation instructions, see:
• Remote-Mount Antenna for Pole Outside Diameters up to 2 Inches, page 34
• Remote-Mount Antenna for Pipe Outside Diameters of 2 3/8 Inches, page 35
