Lumenradio CRMX Pluggy Radio Module
Introduction
What is CRMX™
CRMX is an acronym for Cognitive Radio MultipleXer – it is the first smart wireless system to automatically and continuously adapt to its surroundings in real time. CRMX was specifically developed to meet the demand for reliable, easy to use, and cost effective wireless lighting controls.
CRMX Pluggy FX and Pluggy RX
Pluggy Radio Module
Building as a pin-compatible replacement of the W-DMX TiNY module, LumenRadio offers CRXM Pluggy – the first plug-in module compatible with CRMX, CRMX2, W-DMX G3, G4S, and G5. Pluggy is tested according to ETSI EN 300 328 (v2.2.2) as well as pending FCC certification with a modular approval up to 50mW. Pluggy allows for a flexible integration where the option to install the module or not can be done late in the manufacturing process, or even post-sales by a certified service technician.

60-80% | Red = 3.3V, Green = 3.3V, Blue = 0V | |
30-60% | Red = 3.3V, Green = 0V, Blue = 0V | |
<30% | Red = 3.3V, Green = 0V, Blue = 0V, 1Hz blink |
Transmitter (FX version only)
In the transmitter mode, the RGB LED indicates the currently used transmission protocol.
Color | Meaning | Comments |

CRMX | Red = 3.3V, Green = 3.3V, Blue = 3.3V |
W-DMX G3 | Red = 0V, Green = 3.3V, Blue = 0V | |
W-DMX G4S | Red = 3.3V, Green = 0V, Blue = 3.3V |
Link switch input
The link switch input (LINK_SW) can be used to interface with a momentary (monostable) closing push button to facilitate a simple user interface. This is an alternative to using the SPI interface to integrate into a host device’s menu system. This signal internally pulled high to 3.3V. The switch input has several functions, please see the table below for details about the functions of the switch input.
Function | Conditions |
Link | Only for transmitters. Pull signal low (button pressed) for 0.1-1 second. |
Unlink | Hold signal low (button pressed) for >3 seconds. |
Change RX/TX mode | See Mode selection for more info |
Change TX protocol | See Mode selection for more info |
Force firmware update mode | Hold signal low (button pressed) during power on, then release the button. |
DMX Interface
- The UART DMX/RDM interface of the Pluggy module consists of 3 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. DE and DI signals shall both be connected to the direction pin (RS485_DIR).
- The DMX interface can also be used for CMOS/TTL level directly interfacing, for instance to a host CPU.
- NOTE: Signal on RXD pin must NOT exceed 3.3V ! If 5V signal is used, a level shifting circuit must be used – for instance a voltage divider.
- DMX and RDM termination and line bias
- DMX and RDM termination and line bias circuitry are not provided as part of Pluggy (since the data is provided at the TTL level).
- This circuit is left to the device manufacturer to provide as required for each particular application and device.
- 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
- Pluggy 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 start of the last frame, will be treated as a loss of DMX. Pluggy modules in receiver mode will set the RS485 driver IC to input mode until another DMX frame is detected. Pluggy in transmitter mode will keep the RS485 driver in input mode.
CRMX will propagate DMX through the system, maintaining the input frame rate and frame sizexceptof frame rates that exceed those allowed by the DMX 512-A standard. Different generations of W-DMX modes have individual behaviour about frame rate and synchronisation. 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 DMX512-A standard.
DMX start code frames
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) are handled 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 AI and may interleave other RDM frames that are needed to manage the proxy functionality.
This may result in RDM frames appearing on the DMX/RDM interface in a different order than on the input of the transmitter. All RDM frames are handled in compliance with the PLASA E1.20 standard. Pluggy FX in transmitter nodes discards all frames with RDM start code (0xCC) and RDM draft start code (0xF0).
Firmware update
The firmware in Pluggy can be updated. All manufacturers must consider the firmware update options to provide future-proof integrations to the end-user.
DMX interface
The preferred way to update firmware in Pluggy RX and Pluggy FX is via the DMX interface and the CRXM Upgrade cable. This requires the DMX interface to be accessible from outside the fixture. See the link switch section for information on how to set Pluggy into firmware update mode. Use the CRMX Update utility to update the firmware.
Over-the-air (OTA)
Pluggy FX and RX can be updated over the air by utilizing a special software tool that can be obtained from LumenRadio together with the CRXM Upgrade cable. For details about updates or for recommendations, please contact support.
Mode selection (FX version only)
This chapter describes the different methods of selecting between the different flex modes, also known as modes of operation. This only applies to Pluggy FX. Pluggy RX can not be configured for this, as it is only a receiver module.
Flex mode (RX/TX)
The Pluggy FX can act either as receiver or a transmitter of wireless DMX. The mode must be selected for the device to operate in the right way.
Selecting via the input signal
Pin 11 on the module controls the flex mode selection behaviour. Note: Voltage on Pin 11 may not exceed 3.3V.
Voltage | Description |
< 0.5V | Transmitter mode |
1.5-1.8V | Software controlled |
> 2.8V | Receiver mode |
Software-controlled mode selection
At power up, holding the link switch input low while powering up the device, and then releasing the input to go high within 3 seconds will toggle the RX/TX mode. During operation By pressing the link switch shortly 5 times, and then pressing and holding the button for at least 3 seconds, enters TX/RX mode selection. The Status LED will blink to indicate the currently selected mode. Pressthe link switch momentarily to toggle mode, press and hold the link switch for at least 3 seconds to store the selection.

The RGB LED will blink fast in different colors to indicate the currently selected protocol. Press link switch momentarily to toggle mode, press-and-hold the link switch for at least 3 seconds to store the selection.
