A2500R24x – User’s Manual Release Date 09/05/12 Page 5 of 35 1. Overview The A2500R24C and A2500R24A are surface mount modules with an integrated crystal, internal voltage regulator, matching circuitry and filtering. The A2500R24A has an integral antenna, whereas the A2500R24C utilizes an external antenna through a U.FL connector (see Table 1). The modules operate in the global non-licensed 2.

To receive data, a receive command is given, which enables the unit to “listen” for a transmission and when one occurs put the received frame in the FIFO. When neither transmit nor receive is required, the device can enter either an Idle mode, from which it can quickly reenter receive/transmit mode, or a low power sleep mode, from which a crystal startup is also required prior to a receive/transmit operation.

Typical Flow Figure 4 shows the normal operation flow diagram after initial setup of the registers for desired operation. In applications of infrequent data transmissions the transceiver would be in “sleep” mode to save power. From there, it would awaken and then enter “idle” mode.

A2500R24x – User’s Manual Release Date 09/05/12 Page 19 of 35 Some of the most common interferences are listed below. 2.2.1. WLAN Wireless Local Area Networks (WLANs) are divided into a number of overlapping channels. Figure 5 below shows the channels used by WLAN; for the US and Canada, only channels 1-13 may be used. Predominantly, channels 1, 6 and 11 are used to achieve non-overlapping channels.
Page 20 of 35 o A2500R24x – User’s Manual Release Date 09/05/12 These are typically operated on a fixed channel, determined at installation time and can be avoided by using clear channel assessment. It may be useful to change the channel used by the video surveillance equipment also, if possible. 2.2.5.
A2500R24x – User’s Manual Release Date 09/05/12 Page 21 of 35 Table 5 shows available power levels from the device along with the corresponding PA_Table register settings. Users are encouraged to use minimum power required to establish a link, thus minimizing interference and current consumption. Table 5 Output Power vs.

Page 30 of 35 4.3. A2500R24x – User’s Manual Release Date 09/05/12 Soldering AIR Modules may be mounted either manually (for prototyping or low volume production), or automatically for high-volume production. A no-clean tin/silver/copper (SAC) solder is recommended, however lead based no-clean pastes may also be used. CAUTION: AIR Modules are designed for no-clean fluxes only. DO NOT use waterbased fluxes that require aqueous cleaning after solder.
