SiteWERX User Manual WirelessWerx SiteWERX 1June 09 2 2. Description The SiteWERX Location system consists of System Management software residing on a networked PC, a Base Station, and one or more SiteWERX Location Nodes (SLN’s), Figure 1. The Base Station and SLN’s form a communication chain (scatternet) using Bluetooth radios. The Base Station maintains a communication link with the Management Console, allowing the system to be managed by a PC. Mobile devices, such as cell phones and PDAs, running the SiteWERX Mobile Client (SMC) software are able to communicate with an SLN to receive location and real-time messages, reference Figure 1.

The SLN operates with an input of 6 to 15 volts DC, and has a maximum operating current of ≤ 0.070 Amps. A voltage regulator provides 3.3 volts DC to the Bluetooth module t
SiteWERX User Manual WirelessWerx SiteWERX 1June 09 5 2.1.4 Antenna The SLN has an embedded dipole antenna for the transmission and reception of Bluetooth Radio-Frequency (RF) Signals. The antenna is an Antenna Factor chip antenna, ANT-2.45-CHP-x. The antenna physical dimensions are shown in Figure 3. The radiation pattern is shown in Figure 4. The antenna has linear polarization, a 50 ohm input impedance, and is capable of transmitting a continuous output of ≥3 watts.

SiteWERX User Manual WirelessWerx SiteWERX 1June 09 6 2.1.5 Development/Programming Interface The SLN is programmed using a dedicated four-wire serial peripheral interface (SPI). The SPI is also used for real-time debugging / development, and is connected to a PC parallel port via connector and cable assembly made by WirelessWERX. 2.1.6 Status Indicators The SLN has two LED status indicators. One RED LED is illuminated when power is on. A second GREEN LED is illuminated when the Network status is positive. 2.1.7 Enclosure The SLN assembly consists of a PCB mounted in an enclosure 3.0” x 2.5” x 1.5’’. The enclosure material is Polylac-747, an ABS. The enclosure wall thickness is as thin as practical to minimize Radio Frequency signal attenuation and reflections. 2.1.8 Environment The SLN allowable environments for operating and storage are as follows: Operating Temperature -40 to +70 C Storage Temperature -40 to +85 C Operating Humidity 5% to 80% RH, non-condensing
SiteWERX User Manual WirelessWerx SiteWERX 1June 09 7 3. Constraints 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. Instruction to the User This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: * Reorient or relocate the receiving antenna. * Increase the separation between the equipment and receiver. * Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. * Consult the dealer or an experienced radio/TV technician for help. Operation with non-approved equipment is likely to result in interference to radio and TV reception. The user is cautioned that changes and modifications made to the equipment without the approval of manufacturer could void the user's authority to operate this equipment. 4.
