Operation is subject to the following twoconditions: (1) this device may not cause harmful interference, and (2) this device must accept anyinterference received, including interference that may cause undesired operation.Changes or modifications not expressly approved by OCULII LLC could void the user's authority tooperate the equipment.This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject tothe following two conditions: (1) this device may not cause interference, and (2) this device mustaccept any interference, including interference that may cause undesired operation of the deviceLe présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radioexempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doitpas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillageradioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnementModule ManufacturersA note to module manufacturers (responsible parties); module manufacturers are cautioned that all ofthe same labeling requirements apply not only to the module itself, but these statements and labelingrequirements are required to be outlined IN DETAIL such that the OEM or installer has the correctinformation to properly label the final product and place the proper user manual statements in the finalproduct manual.OEMs employing modulesA note to module installers (OEMs, etc.); incorporating a radio module into a final product and beingable to apply the certification numbers (approvals) to the final product means that the product is inadherence to all relevant requirements and restrictions, including antenna-to-user and collocationseparation distances, manual statements and labeling requirements.If the FCC identification number is not visible when the module is installed inside another device,then the outside of the device into which the module is installed must also display a label referring tothe enclosed module. This exterior label can use wording such as the following: ‘‘Contains TransmitterModule FCC ID: RB7-VISDAR-RADAR”.
OCULII LLCThis device is a K-band (24.075GHz - 24.175GHz ) radar unit used for providing analog signals to anend user which can in turn be used to determine the range, range-rate, and angle of arrival of movingobjects within the device’s field of view. The device is comprised of three main components. Thefirst is an OEM K-band transceiver with integrated transmit and receive antennas. The second part isa radar signal conditioning and calibration board which provides the required filtering of the radaroutput signals as well as provides the digital instructions for programming the OEM radar. The lastpart is a single power to dual power supply converter chip which provides the dual supply voltagesneeded for the analog filters and radar power.This device is set to operate in the K-band. The radar unit is an OEM device with a single integratedtransmit antenna and two integrated receive antennas. Antenna patterns for the transmit and receiveantennas can be seen in Figures 1. An attached companion board provides a parallel network ofanalog filters to condition the two sets of raw quadrature-phase and in-phase radar outputs from thetwo receivers. This companion board also provides a microprocessor to program the OEM radar inorder to provide temperature compensation for the device, provide external clocking signals requiredfor an end user’s data acquisition device, provide a serial user interface to provide feedback from thedevice, and to provide the inputs to the digital to analog converters which drive the OEM radar’sVCO. Finally, the device has an external inline single supply to dual supply converter which takes ina 12V source (battery or OEM AC/DC converter) and converts that 12V supply into a ±12V supply,which is required to power both the radar and the parallel conditioning filters. Once powered thedevice will adjust the tuning voltage based on the device temperature to grantee the device will meetthe FCC guidelines. Temperature compensating will continuously be performed every ten seconds inorder to keep the device within the allotted band.OverviewDescription3830 A Space Drive • Beavercreek , Ohio 45434 Phone: (937) 912-9261 • Email: info@oculii.com • Web: www.oculii.com The Industry Canada certification label of a module shall be clearly visible at all times wheninstalled in the host device, otherwise the host device must be labeled to display the IndustryCanada certification number of the module, preceded by the words "Contains transmitter module",or the word "Contains", or similar wording expressing the same meaning, as follows:“Contains transmitter module IC: 10770A- VISDARRADR”.The applicant for equipment certification of the module shall provide with each unit of the moduleeither a label such as described above, or an explanation and instructions to the user as to the hostdevice labeling requirements.

OCULII LLC830 A Space Drive • Beavercreek , Ohio 45434 Phone: (937) 912-9261 • Email: info@oculii.com • Web: www.oculii.com Step 1: Connect the single supply to dual supply adapter and the serial to USB adapter to thecomponent side of the module. The single supply to dual supply connector uses a three pin polarizedJST connector and plugs in on the lower center of the board and labeled “PWR”. The serial to USBadapter plugs into a row of male headers on the lower right side of the module labeled “SERIAL”.The black wire on the cable should be oriented downwards as seen in Figure 2.Figure 2: Power supply and serial to USB adapter installation.Step 2: Connect the other end of the serial to USB adapter into a source PC with the appropriateUSB to serial drivers. From a serial terminal on that PC (eg. hyperterminal, realterm) open the USBto serial port to allow commands to be sent.8Basic Setup Procedure:

Two red power LEDs should illuminate as seen in Figure 3.Figure 3: Device with power LEDs activated.Step 4: From this point, the device can be switched between standby and operating modes using theserial terminal. To move from the standby mode to the operating mode an ‘s’ must be sent over theserial channel and to move from the operating mode to standby mode an ‘x’ over the serial channel.In operating mode an additional LED will activate as seen in Figure 4.Figure 4: Device with power LEDs and operating mode LED activated.9
