Locus OS2401 802.
REGULATORY APPROVALS United States FCC & Industry Canada rules Compliance Statement The following statements must be included in the product documentation for the end device in which the radio module is embedded: This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
Antenna spacing requirements for user safety It is important to keep the radio’s antenna a safe distance from the user. To meet the requirements of FCC part 2.1091 for radio frequency radiation exposure, this radio must be used in such a way as to guarantee at least 20 cm between the antenna and users. Greater distances are required for high-gain antennas; for more details, see the Choosing the Antennas section.

Product Overview The Locus OS2401 is an 802.11b MiniPCI radio that has been approved by the FCC for use with an external amplifier. The MiniPCI radio can be integrated into industrial devices to provide 802.11b wireless connectivity. Module Integration Module Physical Dimensions The diagram below shows the dimensions of a MiniPCI TypeIIIA card.
Module Connections Mini-PCI Port Digital connection is through Mini PCI type III defined by the Mini PCI Specification document published by the PCI Special Interest Group. As a recommendation, the Molex 67315-0011 can be used.

Antennas and Amplifier Use Bi Directional Amplifier A Bi-Directional Amplifier may be needed if an application requires long lengths of coaxial cable to reach the antenna. The amplifier is designed to put maximum transmit power right at the antenna and boost the received signal primarily to overcome the cable loss. Only the RF Linx 2400LX-0.5W approved amplifier may be used. Note: The RF Linx 2400LX-0.
Choosing the Antennas Antenna section is dependent on whether the Bi-Directional amplifier is being used or not. The minimum distance column in the tables below dictates how far the antennas must be separated from users for safe exposure limits according to FCC Part 2.1091. Approved Antennas Antennas Approved for Use without Bi-Directional Amplifier When the module is connected directly to an antenna, the following antennas may be used: Antenna Type ½ Wave ½ Wave, art. Collinear Array Collinear Array, art.
Antenna Descriptions When selecting antennas to install with the OS2400-HSE in the U.S. and Canada, you can only use models that are specifically approved by the U.S. Federal Communications Commission (FCC) and Industry Canada. See Approved antennas for more details.
Antenna polarity Antenna polarization refers to the direction in which the electromagnetic field lines point as energy radiates away from the antenna. In general, the polarization is elliptical. The simplest and most common form of this elliptical polarization is a straight line, or linear polarization. Of the transmitted power that reaches the receiving antenna, only the portion that has the same polarization as the receiving antenna polarization is actually received.
Elements on one side of the fed element are longer and act as reflectors; elements on the other side are shorter and act as directors. This causes the antenna pattern to radiate in a beam pointed along the boom toward the end with the shorter elements. The pattern and beam width depend on the overall antenna geometry, including the number of elements, element spacing, and element length, but they are generally proportional to the length, where longer length produces a narrower beam.
