The recommended schematic configuration for all of the interfaces and GPIOs are shown as
figure 4. The connection block diagram of the PCI-e interface is shown in figure 5. However,
the connection block diagram of UART and PCN interfaces is shown in figure 6. The PCI-e
differential pair signals impedance target is 100 ohms impedance. The length difference of
each pair of differential signals does not exceed 10 mil, and the integrity of a ground plane
should be maintained, as far as possible.

Federal Communication Commission Interference Statement:
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.
Any changes or modifications not expressly approved by the party responsible for compliance
could void your authority to operate the equipment.
RF exposure statements
This Transmitter must not be co‐located or operating in conjunction with any other antenna or
transmitter.
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body or nearby persons.
CFR 47 FCC PART 15 SUBPART C (15.247) and SUBPART E (15.407) has been investigated. It
is applicable to the modular transmitter.
The devices must be installed and used in strict accordance with the manufacturer's instructions
as described in the user documentation that comes with the product.
This radio transmitter RYK-WNFB265AXIBT has been approved by Federal Communications

Commission to operate with the antenna types listed below, with the maximum permissible gain
indicated. Antenna types not included in this list that have a gain greater than the maximum gain
indicated for any type listed are strictly prohibited for use with this device.
Unique antenna connector (RP-SMA) must be used on the Part 15 authorized transmitters used in
the host product.

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
to the enclosed module. This exterior label can use wording such as the following: “Contains
Transmitter Module FCC ID: RYK-WNFB265AXIBT” Or “Contains FCC ID: RYK-WNFB265AXIBT”
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter
rules) listed on the grant, and the host product manufacturer is responsible for compliance to any
other FCC rules that apply to the host not covered by the modular transmitter grant of certification.
The final host product still requires Part 15 Subpart B compliance testing with the modular
transmitter installed.
