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. In mobile device with battery, VCC36P can be connected to battery power directly. VCC36 pins need to external LDO (or another device). As the Host control the LDO’s enable, user control power down mode of module. If you do not control external LDO, you can control CSE pin to enter power down mode instead. 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.

2 March 2018 13 of 14 RED4S User’s Manuals - Preliminary Version FCC Information to User 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-RED4S” OEM Responsibilities to comply with FCC 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. - The end product must have a power supply regulation circuit. The supply voltage for this module is 3.3~3.6V. Please refer to the installation guide.(on page 5) As long as the 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.
2 March 2018 14 of 14 RED4S User’s Manuals - Preliminary Version 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. Note - Peak Gain Part Name ANT 3.72 dBi KSA – 921A6015B100B
