Ni-Cad, Alkalines, Ni-MH and Li-Ion cells may all be used. Cicada does require 5 AA cells with at least 1500 mAh per cell. BVS supplies 2 bat- tery packs complete with 10 Ni-MH battery cells to get users working right out of the box.

BACKLIGHT ADJUSTMENT At anytime, press 1 key to toggle the backlght off and on. Remember that using the Cicada without the backlight on will increase overall battery life. WEP ENCRYPTION DETECTION A “P” next to its associated AP address and signal strength indicates that WEP (Wireless Equivalent Privacy) is enabled and deteced for that particular AP. -
Page 11: Networking Basics
Networking Basics Packets and traffic Information travels across a network in chunks called “packets.” Each packet has a header that tells where the packet is from and where it’s going, similar to what you write on the envelope when you send a letter. The flow of all these packets on the network is called “traffic.”... - Page 12 TCP/IP (Transport Control Protocol/Internet Protocol) TCP/IP is a collection of protocols that underlies almost every form of communication on the Internet. DHCP (Dynamic Host Control Protocol) DHCP is a method of automatically assigning IP addresses. Instead of assigning addresses to individual users, addresses are assigned by the DHCP server when clients need them.

Page 15: Cicada Serial Interface (Data Logger)
The CICADA Serial Interface software allows complete control of the CICADA IEEE 802 scanner. All data displayed on the CICADA LCD is also displayed on the PC screen. Data received by the PC software can be saved in disk files for later replay and conversion. Each measurement screen of the CICADA is duplicated by the PC software. -

GPS receiver. At least 3 satellites are required for GPS lock. The tool bar GPS Status button indicates lock status with two indicators. These indicators are GREEN if the GPS is locked, RED if not. If the indicators are the same color as the button, the Cicada GPS is off. -
Page 17: Unit Setup Screen
UNIT SETUP SCREEN Clicking the menu View Unit Data button will cause the Cicada connected to the PC serial port to send its unit data which is displayed in a dialog. When using BVS Dolphin plotting software, this information must be available. When making data files that will be replayed for plotting, display this dialog just after turning on Data save. -
Page 18: Menu Selections
3 If connected to the Cicada via PC serial port, get the Cicada Setups by clicking the “View Unit Data ” menu button. If using Dolphin later with replay, make sure to do this just after turning on the data file save so that the Cicada serial number is recorded in the data save file. - Page 19 Pause Replay: Click this button to pause the current disk file replay. The Cicada status bar is used to display current program status using 7 indicators as shown above. 1 -- Displays the current serial connection. It will indicate “Not Connected” if a serial port has not been selected and during file replay.

Page 22: Chameleon Wlan Data Conversion Application
BVS CHAMELEON DATA CONVERSION UTILTTY Introduction The Chameleon application software is the universal data conversion and filtering tool for BVS Receivers. The Chameleon was designed to greatly simplify the transfer of receiver data to many popular post-pro- cessing applications such as MapInfo and MS Excel. The following sections of this document outline the various features of the Chameleon WLAN software. - Page 23 Output Format By selecting the appropriate post-processing application, the correct fields will be selected and placed in the field selection screen in the appropriate order. The user may also choose “none”. Whether or not the field titles are in the output can be selected. Also, the delimiting character of the fields in the output file is chosen in this section.
