Introduction
Promote RMI is the base for Profoto’s versatile modular communication platform, used
in products such as the flash generator Pro-8a 1200 Air. It utilzes communication in the
2.4GHz ISM- band and has an impressive performance with a range of up to 300 meters.
General Description
The Promote RMI module is powered by an 8-bit micro processor with a radio transceiver
from Chipcon 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.

Interface Description
The interface to the host system is implemented as a 16 pin male connector.
The part used on the Promote RMI module is an AMP Micro-MaTch (P/N: 8-215464-6).
The recommended matching female connector is P/N: 8-215079-6. It is recommended
to connect the module with a female header mounted in through holes. This allows for
optimum space saving and leaves the antenna connector easily accessible.
UART Serial Interface
The UART is using pins 1, 8 and 15. To connect to an RS232 line you must use a TTL
level converter (a dongle from B&B Electronics is recommended) from 3.3V or use the
Promote USB dongle which mates with an RMI module and provides a USB interface to
a computer.
Serial characteristics: 38400. 8, N, 1 (no flow control)
NOTE!
Connecting the module to an RS232 line without a line level converter may
damage the module.
For a list of available commands please refer to the RS Toolbox documentation.
Reset Interface
The following conditions will lead to a reset on the Promote RMI module:
• Poweronreset

Important Integration Notes
Promote RMI has been designed to allow for easy integration with a wide range of devices.
There are some key factors you need to consider when integrating the module.
Mechanical Integration
The module needs at least 10 mm clearance in order to fit. This is the maximum height with
consideration to the connector pins. The module has an RF-shield made of nickel silver which
protects all RF-parts (transceiver, power amplifier and VCO). On the module’s backside
there is a test point underneath the antenna which must be protected from user access.
The module should arrive with a label with the serial number printed on it, which should
cover the test point.

Electrical Integration
The minimum connections needed for operation are:
PIN Function Comment
1 GND Digital ground
2 VCC Transmit mode
5 Trig Active high
7 Sync Active high
In order to update the firmware the following pins is needed in addition to the ones
mentioned above:
8 COM TX Transmit to host
9 Reset
15 COM RX Receive from host
16 +3V CPU CPU power supply
Antenna Integration
The Promote RMI module is available in two configurations, one with an integrated chip
antenna and one with an external antenna connector. Special care has to be taken when
choosing which option to use and should be done in connection with Profoto. The module
has been certified with an external antenna which is orderable as an option. The use of any
other antenna is not approved and will break the modular approval.
The connector part used on the module is an Amphenol U.FL series, type U.FL SMT,
reference no. A-1JB.
Ready made cable sets are available with the Amphenol connectors already mounted.
Please contact Profoto for accessories. Antenna design is a crucial topic during integration
and design of radio systems. The antenna must provide good omni-directional radiation.
Poor antenna integration may lead to significant degradation of system performance
and / or affect the reliability.

Regulatory Information
World-wide Usage of Radio Spectrum
The Promote RMI operates on the license-free 2.4GHz ISM band for SRD (Short Range
Devices). This band may be used in most parts of the world. Regional restrictions may
apply.
All data are to be considered as nominal and Profoto reserves the right to make changes without further notice.
NOTE!
Refer to national regulations for the region where the Promote RMI module
shall be operated and make sure that they are followed.
Europe
Promote RMI has been tested towards ETSI EN 300 328. For each end product- it is required
to perform EMC testing according to ETSI EN 300 489-3. Only limited radio tests will be
required since the modules test report can be applied. Once approved and CE marked,
the system may be sold and used in EU/EEC countries without the need to have country-
specific approval tests. However, a notification procedure is necessary in the member
states of the European Union, this has already been done by Profoto. Please contact Profoto
and we will assist you with conformance testing, approval, and notification procedures.
EU Notification
The Promote RMI has been notified in the EU member states and can be used without
further actions in those countries.
