Interrupts
The IRQ pin is used to indicate that there is one (or more) pending interrupt that have
been enabled through the IRQ_MASK register. The IRQ pin is also used to indicate that
the SPI slave is ready to receive the second transaction of an ongoing SPI command
sequence.
The IRQ pin will always go high (inactive) after a successful SPI transaction. If any
interrupts are pending, or when the chip is ready for the second transaction in a SPI
command sequence it will be indicated through a high-to-low transition on the IRQ pin.
RX_DMX_IRQ
Asserted when a complete DMX frame has been received. Cleared by issuing a
READ_DMX command sequence.
LOST_DMX_IRQ
Asserted when DMX stream is lost. This may be an effect of losing radio link, or if DMX
stream in to the transmitter is terminated (for instance the DMX cable to the transmitter
is unplugged). Cleared by reading the STATUS register.
DMX_CHANGED_IRQ
Asserted when a complete DMX frame has been received and any slot within the DMX
window has changed value. Cleared by issuing a READ_DMX command sequence.
RF_LINK_IRQ
Asserted whenever the state of the radio link has changed. This may be:
x radio link is lost
x radio link is established
x receiver got paired to transmitter
x receiver got unpaired from transmitter
Cleared by reading the STATUS register.
ASC_IRQ
Asserted when a complete ASC frame has been received. Cleared by reading the
ASC_FRAME register.
DMX Window register
The DMX_WINDOW register is used for setting up the DMX window filtering function.
Please refer to the section about DMX window on page 19 for more details.
Antenna selection
This register allows for controlling if the on-board chip antenna or an external antenna
connected to the IPEX/u.FL connector is being used. This register overrides the selection
made via the ANT_SEL pin. ANT_SEL pin is internally pulled high to default to IPEX/u.FL
connector.
Ͳ17Ͳ
Version register
This section describes the data that can be read from the VERSION register.
Hardware revision
Hardware revision is a 32bit number that shall be translated into a string. It indicates
the revision number of the TiMo module. For instance the 32 bit value in hexadecimal
form 0x000A0001 corresponds to module revision “000A0001”.
Driver version
The driver version is a 32bit value that shall be translated into a string on the form
X.Y.Z.Y where X is the most significant byte of the 32 bit version number and Y is the
least significant byte. For instance the 32 bit value 0x01000103 shall be presented as
1.0.1.3 on any UI or in any written representation.
Binding UID
The binding UID register can be written by the host processor to match the fixture’s RDM
UID. This will result in SuperNova combing the devices together in the UI representation,
resulting in a better user experience with a more user-friendly interface.
Ͳ18Ͳ
DMX Interface
SPI
DMX data is available to be read over SPI. This applies to both Null Start Code (NSC)
data and Alternate Start Code (ASC) data.
DMX window
The DMX window feature allows a host CPU to set up a span of DMX slots (aka. a DMX
window) that the host is interested of. This will reduce the load of the host since it does
not need to buffer and parse the entire DMX frame.
Instead the host can get an interrupt request (DMX_CHANGED_IRQ) from TiMo RX RDM
whenever data has changed inside the DMX window.
RX_DMX_IRQ is not affected by the settings of the DMX window.
Relevant data
SC
Reading DMX data over SPI
When reading DMX data over SPI, the longest block of data possible to read is 128 bytes.
If it is required to read more than 128 bytes this must be done by performing multiple
consecutive READ_DMX command sequences.
The internal data block counter is reset when the end of the DMX window is reached, or
if any other command is being sent to the SPI slave.
Please note that RDM start code messages are not currently supported over the SPI
interface, so RDM communications shall be carried out over the UART DMX/RDM
interface (pins 8, 10, 11 and 12).
UART DMX/RDM interface
The UART DMX/RDM interface of the TiMo RX RDM consist of 4 digital signals that can be
used to interface an RS485 driver IC compliant with the ANSI E1.11 DMX512-A standard
to facilitate a DMX512-A compatible interface. Please refer to the example schematic for
details on how to connect an RS485 driver IC.
The DMX interface can also be used for CMOS/TTL level directly interfacing for instance a
host CPU.
NOTE: Signal on RXD pin must NOTexceedV
circuit must be used. Please see example schematics on page 7for details on how to use
a 5V IC.
! If 5V signal is used, a level shifting
DD
DMX and RDM termination and line bias
DMX and RDM termination and line bias circuitry is not provided as part of TiMo (since
the data is provided at TTL level). This circuit is left to the device manufacturer to
provide as required for each particular application and device.
Ͳ19Ͳ
Termination and line bias circuitry requirements shall follow ”ANSI E1.20 - 2006 /
Entertainment Technology-RDM-Remote Device Management over USITT DMX512
Networks”or later revisions.
IMPORTANT: Biasing is mandatory for all RDM implementations.
DMX frame rate and size
TiMo RX RDM will auto sense the DMX frame rate and frame size and accept all
variations that are within the USITT DMX-512 (1986 & 1990) and DMX-512-A standards.
Minimum DMX frame size is 1 slot and maximum is 512 slots.
Minimum DMX frame rate for normal operation is 0.8 frames per second and maximum
is 830 frames per second.
Input frame rates below 0.8 frames per second, i.e. more than 1.25s has elapsed since
the last frame, will be treated as a loss of DMX and the RS485 driverIC will be set in a
high-impedance/tri-state mode until another DMX frame is detected.
CRMX will propagate DMX through the system maintaining the input frame rate and
frame size with the exception of frame rates that exceed those allowed by the DMX 512A standard.
Input DMX frame rates above 830 frames per second will propagate through the system
at 830 frames per second to ensure that the DMX output is compliant with the DMX512A standard.
DMX start codes
DMX packets with start codes other than the DMX default 0x00 (also known as the Null
Start Code, or NSC) and the RDM start code (0xCC) will be propagated through the
system, and are subject to the same rules and limitations as the null start code packets.
Such frames are called Alternate Start Code, or ASC, frames.
RDM start code frames
Frames with RDM start code (0xCC) arehandled separately by transmitters in CRMX
systems, as part of the proxy functionality. Transmitters manage the interleaving of RDM
frames with null start code packets across the air, and may interleave other RDM frames
that are needed to manage the proxy functionality. This may result in RDM frames can
appear on the DMX/RDM interface in a different order than on the input of the
transmitter.
All RDM frames are handling in compliance with the PLASA E1.20 standard.
Alternate start code frames
ASC (Alternate Start Code) frames can be read separately from the SPI interface or the
DMX/RDM interface. Over SPI, the ASC_FRAME register contains basic information about
the last received ASC frame. The information available in this register is start code and
length (number of slots).
Ͳ20Ͳ
Reading ASC data over SPI
When reading ASC data over SPI, the longest block of data possible to read is 128 bytes.
If it is required to read more than 128 bytes this must be done by performing multiple
consecutive READ_ASC command sequences.
The internal data block counter is reset when the end of the ASC frame is reached, or if
any other command is being sent to the SPI slave.
Ͳ21Ͳ
Output Power
The radio output power of the TiMo module can not be directly controlled. Instead the
radio output power is automatically adjusted to match the output power from the
transmitter.
Radio driver update
The radio drivers in TiMo RX RDM can be updated. This can be performed via SPI from a
host processor in a fixture, or over the air or via the DMX/RDM interface.
For details about updates, please contact LumenRadio.
