2: Functional Description Figure 2-6 Reverse-SMA to U.FL(short) (P/N 500-182-R) Antenna Placement (xPico Wi-Fi only) When designing the xPico Wi-Fi module to a mating board, it is important to consider the final installation of the unit and its location with respect to connecting access points. The antenna should be placed so that it has as clear as possible path to the connecting access point for maximum range. Avoid placing the antenna such that it is blocked by metal walls or ground planes of adjacent circuit boards. Note: Refer to antenna placement instructions located at http://www.lantronix.com/support/downloads/. This document is located under the xPico Wi-Fi product line. Ethernet Interface (xPico wired only) xPico embedded device server integrates an internal 10/100Mbps Ethernet MAC and PHY. An external magnetic module and RJ45 is required in order to connect to a standard 10/100Mbps Ethernet network.
