Any modifications will break the modular certification and require the module to be re-certified. Introduction RMIX is the base for the next generation of Profotos versatile modular communication platform. It is based on the communication in the 2.4GHz ISM- band and has impressive performance with a range of up to 300 meters. General Description The RMIX module is powered by an 8-bit micro processor with a radio transceiver from Texas Instrument and features a complete feature set for wireless interaction with the Profoto Air range of professional studio equipment. The module has a 3V UART for interaction with a wide range of devices including computers and other microcontrollers.

UART Serial Interface The UART is using pins 1, 15 and 16. To connect to a RS232 line you must use a TTL converter (a dongle from B&B Electronics is recommended) from 3V to 12V. Serial characteristics: 38400. 8, N, 1 (no flow control) For a list of available commands see the software documentation. NOTE!
Connecting the module to a UART port without a line level converter may damage the module. Reset interface The following conditions will lead to a reset on the RMIX module:

There are some key factors you need to consider when integrating the module. Mechanical Integration The module needs at least 3 mm clearance in order to fit.. The module should arrive with a 4x4 mm Data Matrix label which holds the model number, serial number and firmware information. Electrical Integration The minimum connections needed for operation is:
PIN Function 1 2 5 6 8 9 12 15 GND
+3V GND
+3V COM TX Reset TTL COM RX Comment Radio ground Radio power CPU ground CPU power UART output Active low Active low UART input Antenna Integration The RMIX module is available in one configuration with an integrated chip antenna. The antenna should not be modified in any way, doing so will void the approvals for the module. Certification information The module has successfully undergone testing according to EN 300 328 V2.1.1, FCC 47 CFR Part 15, IC RSS -
247 Issue 2 and Japanese Ordinance concerning Technical Regulations Conformity Certification etc. of Specified Radio Equipment Article 2, Clause 1, Item 19. For end products using the RMIX module (as the only radio module), the following applies:
CE (EU/EES) The RMIX module is in conformity with the essential requirements and other relevant requirements of the Radio Equipment Directive (2014/53/EU). Please note that every end product using the RMIX module will need to undergo EMC testing according to EN 301 489-17 V3.1.1 (or later). For RF, conduced test results can be inherited from the RMIX test report to the end product using RMIX. Limited EN 300 328 V2.1.1 (or later) testing for radiated spurious emission is necessary and the test must be repeated with the end product using the RMIX module. FCC (USA) FCC Compliance Statement (Part 15.19) This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference, and 2. This device must accept any interference received, including interference that may cause undesired operation. Warning (Part 15.21) Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01 2.2 List of applicable FCC rules 15C 2.3 Specific operational use conditions This module is approved for use in portable and mobile applications. Integrators must supply operating instructions for end users and installers to satisfy RF exposure compliance requirements are met. Integrators and installers must also make sure that compliance with Part 15B are ensured. 2.4 Limited module procedures This module is not shielded and therefore requires radiated emissions tests in each new host product. 2.5 Trace antenna designs N/A, the module does not use a trace antenna, it uses a SMT chip antenna. 2.6 RF exposure considerations WARNING: The RMIX device radiates radio frequency energy at a level below the United States FCC radio frequency exposure limits. Nevertheless, this device should be used in such a manner that the potential for human contact during normal operation is minimized. For hand held operation, this device has been tested and meets FCC RF exposure guidelines when the device is positioned a minimum of 1.0 cm from the body. For on camera mounted operation, this device has been tested and meets FCC RF exposure guidelines when the device is positioned a minimum of 2.0 cm from the head and must not be co-located or operating in conjunction with any other antenna or transmitter. As long as the two conditions above are 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.). 2.7 Antennas Antenna is Fractus Compact Reach Xtend, P/N: FR05-
S1-N-0-102. 2.8 Label and compliance information The RMIX module is labelled with its own FCC and IC ID. If the FCC and IC ID:s 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 physical label or eLabel referring to the enclosed module. In that case the end product must be labelled in a visible area with the following: Contains FCC ID: W4G-RMIX and IC: 8167A-RMIX IMPORTANT NOTE:
In the event that these conditions cannot be met (for certain configurations or co-location with another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and the FCC ID and IC Certification Number cannot be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC and Industry Canada authorization. IC Compliance Statement (Canada) This Device complies with Industry Canada License-
exempt RSS standard(s). Operation is subject to the following two conditions:
1) this device may not cause interference, and 2) this device must accept any interference, including interference that may cause undesired operation of the device. Le prsent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes:
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. IC RF Exposure limits The RMIX device complies with the IC RSS-102 radiation exposure limits set forth for an uncontrolled environment. For hand held operation, this device has been tested and meets IC RF exposure limits when the device is positioned a minimum of 1.0 cm from the body. For on camera mounted operation, this device has been tested and meets IC RF exposure limits when the device is position a minimum of 2.0 cm from the head Limites dexposition RF IC Le dispositif RMIX est conforme aux limites sur lexposition aux rayonnements IC RSS-102 dfinies pour un environnement non contrl. En mode manuel, ce dispositif a t test et respecte les limites dexposition IC RF lorsque ce dernier est plac au moins 1 cm du corps.
