2 Operation Method
Figure 2 Application Circuit
2.1 Power Supply
DC power to operate RED4 is separated by 2 kinds. VCC36 is to supply for PR9200 which power range is 3.3
to 3.6 volts, VCC36P is to supply for power amp which power range is 3.3 to 4.2 volts. Total current consumption
of RED4 is typically 450mA at 25dBm 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 RED4 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 and synchronize parameters with REDx module automatically. If the GUI cannot find
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.

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 equipment
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 manual, may cause harmful 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
This device 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 technical for help.
End Product Labeling
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 must also display a label
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-RED4”
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
ismaintained between the radiator (antenna) and all persons at all times.
- The module is limited to installation in mobile or fixed applications.
- The transmitter module must not be co-located or operating in conjunction with any other antenna
ortransmitter except in accordance with FCC multi-transmitter product procedures.
- Separate approval will be required for all other operating configurations, including
portableconfigurations with respect to Part 2.1093 and different antenna configurations other than
suppliedantennas.
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.).

RED4 User’s Manuals - Preliminary Version
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.
This module has to install the input the 3.3V, cause there is no regulator in the device.
This device may only operate using an antenna of a type and maximum (or lesser) gain approved by
Phychips. Antenna types not included in the list, having a gain greater than the maximum gain indicated
for that type, are strictly prohibited for use with this transmitter.
