* Actual RF range performance is subject to a number of installation-specific variables including, but not restricted to ambient temperature, relative humidity, presence of active interference sources, line-of-sight obstacles, near-presence of objects (for example, trees, walls, signage, and so on) that may induce multipath fading. As a result, actual performance varies for each instance. Antenna Specifications 4.2 The antenna must meet specifications in Table 8. Table 8 Antenna Specifications Parameter Value 2.42.4835 GHz Frequency range Impedance Maximum VSWR Antenna Connector When the RM2510 is placed inside an enclosure, the antenna should be mounted such that the radiating portion of the antenna protrudes from the enclosure, and connected using a coaxial cable. For optimum performance, allow the antenna to be positioned vertically when installed. 5.0 The following is the pinout for the RM2510 module.
