Ͳ8ͲReference design files A complete reference design including PCB layout and PCB design guidelines is available from LumenRadio to make integration easier. Please send your inquiry to LumenRadio for details. PCB mounting Internal or External Antenna? For short distances the modules´ internal antenna will perform well. But if the design is to be placed inside a metal enclosure, or if there is a need to cover large distances, an external antenna is necessary. An external antenna MUST at least be designed for operation between 2.4 – 2.48GHz Always use external antennas with a 50ς characteristic impedance. Internal Antenna If the internal antenna is considered, the product case needs to be of a RF transparent plastic material. The circuit board that will hold TiMo needs to be designed so that the internal chip antenna radiates efficiently. Avoid any ground planes near the antenna chip. When placing TiMo on a circuit board: xPlace the module as close to the host circuit board edge as possible with the antenna pointing outward. xNote the absence of ground plane near the chip antenna on the modules´ circuit board. xRemove any copper from the main board as specified in section “LayoutExampleLayout Examples” xAvoid using metal structures such as mounting hardware close to the antenna chip. Layout considerations for the main (Customer) board. TiMo has been specifically designed in order to achieve good RF performance. In order to maintain this, there are some guidelines that we would like to stress: The use of ground planes also on the main board cannot be overemphasized. Good decoupling of any high speed digital circuitry is a must. Many embedded type microprocessors today has clock frequencies with clocks or over tones that reaches well into the GHz range. It is perfectly possible for an embedded design to pass any EMC certification and still cause disturbances that will block the RF reception of the TiMo module. The sensitivity of the TiMo receiver is -96dBm therefore it is recommended to keep disturbances below -100dBm in the frequency range of operation ᑖṬᔿⲴ

Ͳ9ͲA near field probe connected to a spectrum analyzer will show if there are any disturbances present on the 2.45 GHz band generated by the microprocessor or any other device that is placed on the main board. Pay special attention to readymade LAN-products "Server in a RJ connector". They pass EMC certifications, but some of them radiates badly on 2.45 GHz. If disturbances can be seen on a spectrum analyzer - then the TiMo module will have impaired reception. TiMo has a supply voltage decoupling on the circuit board. The supply voltage still needs to be adequately filtered. If any disturbance or intermittent communication failures occur, as one of the trouble shooting steps - check the supply voltage for drop-outs, switch supply ripple etc. Layout Example 1. The TOP layer inside the footprint must be free from copper. There is a ground plane on TiMo, but there are also supply lines. It is an unnecessary risk to rely on solder mask lacquer for isolation. 2. The area around the antenna must be kept clear from copper on all layers. This is shown in the picture below. This shows inner layer 1 (next to TOP)

Ͳ11ͲTiMo reflow soldering specification TiMo is a surface mount device (SMD) designed to be easily manufactured including reflow soldering to a PCB.It isultimately theresponsibility of the customer to choose the appropriate solder paste and to ensure oventemperatures during reflow meet the requirements of the solder paste. TiMo surface mount module conforms to JSTD-020D1 standards for reflow temperatures. Temperatures should not exceed the minimums or maximums presented in table below: SpecificationValueUnitTemperatureInc./Dec.Rate(max)1~3°C/secTemperatureDecreaserate(goal)2Ǧ4°C/secSoakTempIncreaserate(goal).5Ǧ1°C/secFluxSoakPeriod(min)70secFluxSoakPeriod(max)120secFluxSoakTemp(min)150°CFluxSoakTemp(max)190°CTimeAboveLiquidous(max)70secTimeAboveLiquidous(min)50secTimeInTargetReflowRange(goal)30secTimeAtAbsolutePeak(max)5secLiquidousTemperature(SAC305)218°CLowerTargetReflowTemperature225°CUpperTargetReflowTemperature250°CAbsolutePeakTemperature260°C

Ͳ12ͲLED outputs StatusThe status LED (STATUS_LED) indicates the status of the TiMo RX RDM. The LED indicator pin is an output pin capable of sourcing 5mA at the VDD voltage. An appropriate current limiting resistor must be connected in series with the LED. Constant off (0V): Not linked to any transmitter Flashing: off (0V) 100 ms / on (VDD) 100 ms: linked to a transmitter, but no active radio link Flashing: off (0V) 900 ms / on (VDD) 100 ms: Active radio link, no DMX present Constant on (VDD): Active radio link, DMX data present Linked The Linked LED (LINKED) indicates whether the TiMo RX RDM is linked to a transmitter or if it’s available to be linked. High level (VDD) on this pin indicates a linked state; low level (0V) indicates that the TiMo RX RDM is not linked. RF Link A high level (VDD) on the RF Link LED output (RF_LINK) indicates that the TiMo RX RDM is within range from the transmitter it is linked to and that an active radio link from the transmitter is present. DMXThe DMX LED (DMX_LED) indicates if a valid DMX stream is received from the transmitter. A high level (VDD) indicates that DMX is present, a low level (0V) indicates that no valid DMX is present. RDM LED A high level (VDD) on the RDM LED output (RDM_LED) indicates that the TiMo RX RDM is performing RDM activity.

Ͳ13ͲRadio level TiMo RX RDM has 5 output signals for controlling radio level LEDs in the form of a bar graph (RDI_LVL0 - RDI_LVL4). Operation of these, and suggestion of LED colors, can be found in the table below. Signal name Suggested LED color On when signal quality RDI_LVL0 Red below ~10% RDI_LVL1 Amber / Yellow above ~20% RDI_LVL2 Green above ~40% RDI_LVL3 Green above ~60% RDI_LVL4 Green above ~80% Link switch input The link switch input can be used to interface with a momentary closing push button to facilitate a simple user interface when not using the SPI interface to integrate into a host device’s menu system. Please refer to the example schematic for details on how to connect the push button. This signal shall be pulled to VDD using an external 4.7kȍ-10kȍ resistor, when used, to ensure proper function. The switch input has two functions: unlink the receiver from a transmitter or to force driver update mode. Please see the table below for details about the functions of the switch input. Function Conditions Unlink from transmitter Hold signal low (button pressed) for >3 seconds. Force driver update mode Hold signal low (button pressed) during power on. Antenna selection The antenna selection input can be used to select the required RF antenna for use on TiMo RX RDM. This pin is internally pulled high. This pin can be overridden by writing the ANTENNA register. State Conditions High Level (Logical 1) External U.FL/IPEX connector Low Level (Logical 0) Internal Chip Antenna

Ͳ14ͲSPI interface The SPI interface gives access to all features of the TiMo RX RDM. The interface consist of five digital signals (VDD max): xIRQ – Interrupt signal. Active low, configurable through the interrupt mask register. xCS – SPI Chip select, active low. xSCK – SPI clock input xMOSI – SPI data input xMISO – SPI data output Interface description Bit and byte order The data on the SPI bus is clocked with most significant bit first. All multi-byte register data are sent in big-endian byte order. Clock polarity Data is valid in the low-to-high transition of SCK. This is also known as the clock being active high with valid data on the leading clock edge. Maximum clock speed The maximum clock speed supported by TiMo RX RDM is 2MHz. Clock speeds above this limit may result in unexpected behavior. Setup time The SPI slave unit has a setup time of 4 ǋs after the high-to-low transition of the CS signal. SPI operation SPI transactions All SPI transactions start with a high-to-low transition on the CS pin. The CS pin must be held low during the entire SPI transaction. The IRQ_FLAGS register is always shifted out as the first byte of each transaction. Figure 3: Example SPI transaction

Ͳ15ͲSPI commands All SPI command sequences, except for the NOP command, consist of two SPI transactions. The first transaction shall be one byte long, this is the command byte. The second transaction is the payload. The second transaction must not be started until the TiMo RX RDM has confirmed the command by a high-to-low transition on the IRQ pin. The first byte being sent to TiMo RX RDM in the second transaction will be ignored, however it is suggested this byte is being sent as 0xFF. See below for an example full SPI command sequence. NOTE: Bit 7 in the IRQ flags register MUST be observed. A ‘1’ in this bit means that the SPI slave module is unable to process the current transaction, and the full command sequence MUST be restarted – this means sending the command transaction again. Figure 4: Example SPI command sequence with a pending IRQ when sequence started The available SPI commands are listed in the table below. Command Binary value Comment WRITE_REG 01AA AAAA Write to a register. AAAAAA = 6 bit register address READ_REG 00AA AAAA Read from a register. AAAAAA = 6 bit register address READ_DMX 1000 0001 Read the latest received DMX values from the window set up by the DMX_WINDOW register. READ_ASC 1000 0010 Read the latest received ASC frame. NOP 1111 1111 No operation. Can be used as a shortcut to read the IRQ_FLAGS register. RegistermapAll undefined bits in the table below shall be considered reserved for future use - don’t care when read, write as 0. Do not read or write undefined registers – doing so could result in undefined behavior. Address (hex) Mnemonic Bit # Type Reset value Description 00 CONFIG Configuration register UART_EN 0 R/W 1 Enable UART output of DMX frames (required for RDM) Reserved 1-6 - - Reserved for future use RX_ENABLE 7 R/W 1 Enable wireless DMX reception 01 STATUS Status register LINKED 0 R/W - 0 = Not linked, 1 = Linked to TX (or pairing) Write 1 to unlink
