The Hardware Setup and Software InstallationInstallation Directions
See "The Transmitter" for Detail.
Please see 17: For more information on electrodes, see "Electrode Usage and Checking for Bad Connections".
Application and Mac System Recommendation.IBVA4 application size is about 10 MB. To install everything from the CD-ROM need disk, the total disk size is about 600 MB. IBVA4 works with G3, G4, G5 any Mac with OSX10.3.X to OSX10.4.1. Brain wave Data size: about 90 MB for 2 Channel 7 hour recording. Application display and MIDI and other control function update speed depends on the Mac CPU speed and the IBVA4 setup. Minimum CPU speed is 500 MHz; recommended speed 1 GHz. Use with Quick Time Control, and you can also work with other applications, such as music programs, MAX etc., using DP CPU Mac is a good solution. DP 2.7 GHz with 23" to 30" Apple LCD display is a nice setup for brain wave multimedia control system. Using dual display monitors is a nice way to see brain wave and multimedia control. Monitor brain waves while playing MIDI sound works well with the Mini Mac 1.33 GHz. The Transmitter
The transmitter has one switch, an LED indicator light, a 1/8" mini jack output, a sensor jack, a wire antenna (white) connector, and a battery compartment. The switch must be set to "On" to transmit the brainwave data. The LED will blink when a signal is being sent. Set the switch to "Off" whenever you are not using the IBVA system to record brainwaves; this will save battery power. The antenna should be unobstructed when possible and treated with care. The battery compartment slides open and the + and - positions are marked inside. The mini jack output is for recording your brainwave data to a recordable device, such as a portable cassette recorder, MD or camcorder not directly connected to an A/C power source. Never connect the transmitter to a device that is directly plugged into an A/C plug. Only connect to a device that is powered from dry cell batteries. If you intend on connecting to an A/C power source please consult with a professional electrician to ensure that you will be isolated from the A/C power source. The sensor jack connects to the headband or optional sensor equipment. Coherence modified transmitter is two transmitter connecting together for internal clock synchronization. You can put battery into only one side or two side. In case put battery one side then make switch ON only that side. In case put battery two side then make switch ON both side and need to use same two battery. Do not mistake to put battery polarity. The Receiver
On the front of the receiver there are two switches, one LED indicator light, and one 1/8" mini jack input. The left switch turns the receiver on and off. When you are using the IBVA program to record brainwaves this switch must be set to "On". When this switch is set to "Off" the receiver will act as a pass thru box, allowing you to use whatever device is connected to the Output port, like a modem or network connection that has RS422 port. The LED indicator light blinks fast and continuously when it is receiving a good signal and blips noticeably on and off when receiving a poor signal. The LED will only be lit when the IBVA program is open and the receiver is getting a signal. The right switch selects an input mode. When "Tape" is selected the receiver will look for a signal from the 1/8" mini jack input. When "Ante" is selected the receiver will look for a signal from the wireless transmitter. The 1/8" mini jack input is used for connecting to the playback output of a device such as a portable tape player or camcorder. The top of the receiver is where the antenna is connected. The antenna is removable for easy portability. The back of the receiver is where the two serial port connections are. The Input port connects to the computer. The Output port is for connecting other serial devices such as a modem or printer that has RS422 port. New Mac has no serial port. Need to use USB serial adapter and cable to connect receiver's RS422 port, MIDI 8 DIN connector. USB serial adapter is not included in the IBVA system. Connection cable is included in the IBVA system. Need to install device driver for USB serial adapter. Make sure that USB serial adapter's driver software work with your Mac system. For coherence system need to use two specia USB serial adapter for synchronize two channel.

The Headband
There are two types of headbands. A 1 CH (one channel) version and a 2 CH (two channel) version. They both read the frontal lobe of the head (Fp1 and Fp2). The 1 CH version has one output wire and reads the brainwaves from both the left and right hemispheres (in between Fp1 and Fp2) of the brain but has no ability to distinguish what hemisphere the brainwaves come from. For example, if a high peak occurs at a specific frequency in the left hemisphere of the brain and a low peak occurs at the same frequency in the right hemisphere, only the highest peak will be displayed. The 2 CH version of the headband has two output wires for the left and right channels and reads and separates the left and right hemisphere brain data, around Fp1 and Fp2 . The IBVA program can then record and display this information separately. This map show other way to name location. for this way, One channel headband is in between F1 and F2. body ground is Fz. Two channel headband is F1..F7 (right: look to front face, displays in right) and F2..F8 (left: look to front face, displays in left) body ground is ear by ear clip. General Use The transmitter and receiver should be placed within plain sight of each other and as unobstructed as possible. You have approximately 30 feet of wireless operation space but the range will depend on the electrical environment the IBVA is in. When the transmitter is used with a fresh alkaline 9V battery, eight hours of continuous operation should be obtained. A rechargeable battery will last about two hours. Never bend or twist the headband too sharply. There is a thin film connection between the sensors and the output wire. Bending or twisting the headband too sharply will damage the internal connections. The headband can last a decade at least if given proper care. The electrodes that come with the IBVA are standard medical electrodes. For expert medical use, the electrodes should be replaced for each new session. When the IBVA is not being used for expert medical use, the electrodes eventually will become too worn to give a solid connection to the skin, resulting in inaccurate data. 1 Channel systems
2 Channel systems
2 Channel systems use almost duplicate transmitters and receivers, the difference being that they are tuned to different frequencies so the system can tell the difference between the two channels of data. 2 CH systems can be used for reading the brainwaves of two people at the same time with two 1 CH headbands, or the left and right brain hemispheres of an individual with the 2 CH headband. "2 Channel mode" must be selected under the Edit menu within the IBVA program for the 2 CH display to begin for IBVA V1 to IBVA V3 application. 2 Channel and coherence systems IBVA V4 SOFTWARE (CD-ROM) X1 Modified RECEIVER X 1 White antenna for receiver X 2 BAR ANTENNA X 2 TRANSMITTER X 2 2 CH HEADBAND (RLB-00) X 1 CONNECTOR CABLE (MINI 8 DIN - DB 9) X 2 4 PKG ELECTRODES (6 ELECTRODES PER PKG) 2 Channel and coherence systems use modified transmitters, two transmitters are correcting together for synchronize internal clock. Including one 2 CH headband. Not including 1 CH headband. Use for left, right brain hemispheres and coherence analysis. Order parts The transmitter and receiver must purchased as a each unit. ch 1 and/or ch 2 frequency. electrodes, headbands, Pin Input Pack (3 pin adapter) etc. can be purchased as separately. masahiro kahata
