Figure 2 Application Circuit
2.1 Power Supply
DC power for RED5 is VCC IN ( pin2 1,2 2,25 ,26) . T her e ar e 2 LDO insid e module. One is to suppl y for PR92 0 0
which DC voltage is 3.3 volts ( typ.). The other is to supply for VBIAS f or power am p which is 3. 0V. VCCIN is
connected to input of LD Os. Total current consumption of RED5 is typically 1.37A at 30dBm Tx CW output
power.
2.2 UART
The serial interface is assigned with two wires. RXD0, which pin is assigned to pin 35, is for receiving
command from host and TXD0, which pin is assigned to pin 34, is for transmitting response to host. Pin
connection is shown as below figure.

Always use Extended View Mode for measurement.
2.4.2 RED5 Connection
If hardware connection is valid, RED utility connect module REDx automatically.
If utility cannot connect hardware, please follow below step
Click “Connection->Connect” to connect to REDx-DK through USB-to-UART at main window
GUI will find the Device an d synchronize par ameters with REDx m odule automatical ly. If the GUI cannot f ind
the device automatically, Click “Connection->Port Setting” and select other Device. Default Baud rate is
115200 bit/s.
If the Device connected successfully, status bar will display “OPEN” state and device number and so on.

converted to DC 3.3V constant voltage through a regulator to operate the product.
FCC Information to User
This equipment has been tested and found to comply with the limits for a digital device, pursuant to part 15 of
the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipmen t
is operated in a commercial environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manua l, may cause ha r mful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user
will be required to correct the interference at his own expense.
This device complies with Part 15 of FCC Rules. Operation is subject to the following two conditions:
(1) the device may not cause interference, and
(2) the device must accept any interference, including interference that may cause undesired operation of this
device.
Caution : Any changes or modifications in construction of this device which are not expressly approved by the
party responsible for compliance could void the user's authority to operate the equipment
End Product Labeling

Preliminary Version
RED5 User’s Manuals -
The module is labeled with its own FCC. If the FCC ID is not visible when the module is installed inside
another device, then the outside of the device into which the module is installed mus t also disp lay a labe l
referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the
following:
“
Contains FCC ID: Y3D-RED5”
OEM Responsibilities to comply with FCC and Industry Canada Regulations
The module has been certified for integration into products only by OEM integrators under the following
condition:
- The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is
maintained between the radiator (antenna) and all persons at all times.
- The module is limited to installation in mobile or fixed applications.
- The transmitter module mu st not be co-located or operating in conjunc tion with any other a ntenna or
transmitter except in accordance with FCC multi-transmitter product procedures.
- Separate approval will be required for all other operating configurations, including portable
configurations wit h respect to Part 2.1093 and different antenna configur ations other than supplied
antennas.
As long as the two condition above is met, further transmitter testing will not be required. However, the OEM
integrator is still responsible for testing their end-product for any additional compliance requirements required
with this module installed (for example, digital device emissions, PC peripheral requirements, etc.).
In the event that these conditions cannot be met, then the FCC authorizations are no longer considered valid
and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator will be
responsible for re-evaluating the end product including this module and obtaining separate FCC authorizations.
- This device is intended only for OEM integrators
- For OEM integration only – device cannot be sold to general public.
- Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how
to install or remove this RF module in the user’s manual of the end product which integrates
this module.
The antenna matching circuit is a Pi as shown below, and th e m inimum loss is 0dB. The antenna connec tor is
CMJ type, and the distance to the connector is Max 100mm.
