SiteWERX User Manual WirelessWerx SiteWERX 1June09 2 2. Description The SiteWERX Location system consists of System Management software residing on a networked PC, a Bluetooth / WIFI Base Station, and one or more SiteWERX Location Nodes (SLN’s). The SBS-W and SLN’s form a communication chain (scatternet) using Bluetooth radios. The SBS-W uses an 802.11 WIFI module to maintain a communication link with a local area network, allowing the system to be managed by a PC with access to this LAN. Mobile devices, such as cell phones and PDAs, running the SiteWERX Mobile Client (SMC) are able to communicate with an SLN to receive location and real-time messages, reference Figure 1.

One for the transmission and reception of Bluetooth Radio-Frequency (RF) Signals, and one for the transmission and reception of WI-FI Radio-Frequency (RF) Signals. The antennas are 4 inch dipoles with a 50 ohm impedance, and a max gain of 2.89 dBi, Figure 3. The SBS antennas are capable of transmitting a constant 1.0 watt. The SBS antennas have a right angle, reverse polarity SMA connector. The SBS antennas are adjustable and normally operate with the primary axis aligned with the local vertical.

SiteWERX User Manual WirelessWerx SiteWERX 1June09 6 2.2.5 Power Supply The SBS-W module operates from an external AC/DC power supply to provide a regulated DC voltage of 3.3 VDC at 2.18 Amps, and consumes a maximum power of 7.2 Watts. 2.2.6 Power-On Indicator The SBS has a RED LED indicator that is illuminated when power is enabled. 2.2.7 Development/Programming Interface The SBS is programmed using a 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. The development / programming interface shall be designed to permit the following connections: PC connect to WI-FI module only PC connect to Bluetooth module only Bluetooth module to WI-FI module, No connection to PC 2.3 Construction and Packaging The Wireless Base Station is shaped similar to a rectangular with the following dimensions 87in length x5.9in width x 2.3in height. The Enclosure is molded for FRABS UL 94-V0 Plastic. The SBS WI-FI- and Bluetooth modules, and related circuit elements are assembled on a single PCB, and enclosed in a rectangular box, with the following (nominal) dimensions: Length 8.7 inches Width 5.9 inches Height 2.3 inches 2.4 Environment The SiteWERX allowable environments for operating and storage shall be 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 1June09 7 3. Constraints 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.
