Block Diagram
The module contains a communication controller with embedded proprietary protocol software, a
narrow band high performance RF transceiver and three internal voltage regulators.
The communication controller handles the radio packet protocol. Data to be sent by the host is
received at the DATA_RX pin and buffered in the communication controller. The data packet is
then assembled with preamble, synchronization word and data with CRC check sum before it is
transmitted on RF.
The asynchronous UART interface consists of DATA_TX, DATA_RX and CTS/RXTX/RXEN_RADIO
signals and it is used for hardware handshake flow control.
The RF transceiver modulates the data to be transmitted on RF frequency, and demodulates data
that are received. Narrow band technology is used to enhance sensitivity and selectivity.
The supply voltage is connected to the VAccu pin. The module contains three internal voltage
regulators and can therefore operate over a wide supply voltage range.

External antenna installation requirements
The external antenna must be installed at a distance from the class 3 cables and power
components (power supply, motor, variable speed drives …) while remaining in an area which is
favourable to radio reception.
It must be located at a certain height.
No metal object which could form a screen should be located in front of the external antenna (risk
of communication cut-out).

Labelling
!! Warning !!
“This transmitter module is authorized to be used in other devices only by OEM integrators
under the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 20cm is
maintained between the radiator (antenna) & user’s/nearby person’s body at all times.
2. The transmitter module must not be co-located with any other antenna or transmitter.”
Moreover, the host equipment must be labelled as follows:
“Contains Transmitter Module FCC ID: OQMSA”
Finally, the host equipment must precise the following warning:
“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.”
Information Note
This modular is used exclusively by Jay Electronique.
The OEM integrators are responsible for ensuring that the end-user has no manual instructions to
remove or install module.
This module and the antennas must be professionally installed.
A specific ferrite must be attached to the AC line; here its characteristics below:
 Brand name: Laird Technologies
 Product reference: 28B0686-200
 Number of turns: 2
“THE GRANTEE IS NOT RESPONSIBLE FOR ANY CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY
THE PARTY RESPONSIBLE FOR COMPLIANCE. SUCH MODIFICATIONS COULD VOID THE USER’S AUTHORITY
TO OPERATE THE EQUIPMENT.” According to FCC Part 15.21
