DMXking LeDMX2 MAX User Manual

DMXking LeDMX2 MAX

INTRODUCTION

Thanks for purchasing a DMXking product. Our aim is to bring you high quality products with great features we know you’ll appreciate. In many LED pixel installations, especially where the majority of pixels may be running simultaneously at full brightness, it is necessary to inject DC power at various points along the pixel strip/string/array. Although the LeDMX2 MAX can only provide up to 8A per output port terminal block this is not a limitation since currents higher than that will require power injection along the strip anyhow.

HARDWARE AND FIRMWARE VERSIONS

IMPORTANT : In many LED pixel installations, especially where the majority of pixels may be running simultaneously at full brightness, it is necessary to inject DC power at various points along the pixel strip or string. Although the LeDMX4 MAX can only provide up to 8A per output port terminal block this is not a limitation since currents higher than that would require power injection along the strip anyhow. Contact DMXking technical support for additional advice.

eDMX MAX translates Art-Net 00:0:0 to Universe 1 (i.e. offset by 1) so there is an easy mapping between sACN/E1.31 and Art-Net.

CONFIGURATION UTILITY

The eDMX Configuration utility provides a simple interface to all device parameters. Typically, these are set once during initial configuration and left untouched.
eDMX Configuration functions with primary Art-Net UDP 6454 and an alternate UDP 16454 port for device configuration. This is helpful when simultaneously running eDMX Configuration and a lighting control application. Automatic selection of alternate port is performed upon utility startup if the primary Art-Net port is unavailable. It is also possible to lock eDMX Configuration to the alternate port via the Advanced menu. Note that DMXking nodes are always listening on both primary and alternate ports so there is no device configuration required to change.

eDMX Node configuration can be saved/loaded from a simple Key:Value YML file. Select the node and perform Load/Save accessible in the File menu. Configuration files can be loaded from a file named “conf.yml” on the SD card however updates made to configuration are not currently saved by the node back to the conf.yml file. This is intended as a deployment mechanism where complete device configuration and show content can be prepared externally on an SD card.

NETWORK TAB

eDMX Configuration can find and configure eDMX MAX hardware on different IP subnets from the computer network adapter. There are some functions such as the Recorder that require both devices on the same IP subnet range e.g., Computer IP 192.168.0.100 Subnet 255.255.255.0 Gateway 192.168.0.254 when eDMX MAX is on default IP. Upon startup eDMX nodes are automatically detected and displayed by IP address. To poll for new devices or just check the communications is okay by clicking Search. Polling is automatic every 8 seconds but can be disabled through the Advanced |

Auto Device Poll menu option. Mute Responses option prevents any new nodes from being listed regardless of their status on the network. With large node counts this can be helpful. Click on the desired node’s entry and all Settings will be retrieved. Note that if no response is received the settings will be greyed out and no additional tabs visible. An activity box shows both transmitted and received messages to help with diagnosing communication issues. If your network configuration has multiple adapters and or IP addresses you should select the same network range as the eDMX from the Network Adapter IP Address dropdown box and also ensure the subnet mask is appropriate. Settings Broadcast is suppored by eDMX MAX which allows node settings to be updated regardless of the network adapter subnet range. Unicast single node discovery and configuration is possible by selecting Advanced | Unicast Poll and entering the destination IPv4 address then click Search. This will function over routed networks provided a Default Gateway has been specified in the node Network Settings.

eDMX MAX nodes provide IGMPv2 Reports necessary to participate in a multicast environment as necessary for sACN/E1.31 protocol. Sometimes due to network infrastructure issues an IGMP querier is not present and in these situations, you can opt to have the node generate ongoing unsolicited IGMPv2 Reports.

To change the node Network Settings make applicable changes then click Update Network Settings. Selecting Firmware Update will prompt for an appropriate firmware file and upload upon confirmation. A built-in boot loader permits updating of the eDMX firmware. We do not recommend performing firmware updates over routed networks. Note only signed encrypted firmware files from DMXking.com can be successfully loaded to ensure you won’t brick your device by accident. Future firmware releases for this product will be in the form 0128-500-VersionMajor.VersionMinor.enc

Master Level

|

Pixel output master level control for all outputs. Has no effect for Raw Colour Order modes and is overridden by Playback Universe Master Level (see Recorder Manual).

Alternate Master Level

|

Pixel output master level control for all outputs when Alternate Mapping is in effect. Has no effect for Raw Colour Order modes.

Alternate     mapping                     priority threshold

|

sACN Priority below which Alternate Mapping parameters are used if no higher Priority sACN stream is present. Threshold is assessed on the Start Universe only.

Alternate mapping priority threshold. When incoming stream priority is > threshold then Primary mapping applies. Priority <= threshold Alternate mapping applies. For Primary source 100 Priority and Alternate source 50 set threshold between 50 and 99 for example. Note only first universe mapped to pixel port is used to determine priority.

Usage

---|---

Pixel Type

|

Must match your connected Pixel type. There are clock speed options for many pixel types and we recommended slower rates for longer cable runs.

Pixel Count

|

Number of physical pixels in the string. Maximum depends on number of channels per pixel which depends on the Color Order setting. RGB = 680, RGBW = 512, 2ch = 1024, 1ch = 2048,

Raw I+3ch = 512, RGB 16bit = 340, RGBW 16bit = 256.

---|---

Null Pixels

|

Number of pixels to ignore at the start of the pixel strip. Minimum 0. Maximum 16. Commonly used to extend the drive distance from source to the first active pixel.

Color Order

|

DMX channel mapping to pixel elements. RGB, RBG, GRB, GBR, BRG, BGR, raw 1/2/3/4/5ch, 2ch swapped, RGBW, WRGB, WRBG, GRBW, Raw I+3ch, Raw 3ch 16bit, Raw 4ch 16bit, RGB 16bit, RGBW 16bit.

Primary Start Universe

|

sACN/Art-Net Universe number pixels are mapped to.

Primary Start Channel

|

DMX512 channel number pixel data starts from.

Primary Pixel Group Size

|

Multiple sequential pixels can be mapped to a channel group. Set to 255 for ALL pixels regardless of actual Pixel Count.

Primary Zig Zag

|

Reverses pixel direction every N pixels.

Primary Direction

|

Reverse makes pixel 1 appear at the far end of the strip.

Alternate Start Universe

|

Alternate sACN/Art-Net Universe number pixels are mapped to.

Alternate Start Channel

|

Alternate DMX512 channel number pixel data starts from.

Alternate Pixel Group Size

|

Alternate map. Multiple sequential pixels can be mapped to a channel group. Set to 255 for ALL pixels regardless of actual Pixel Count.

Alternate Zig Zag

|

Alternate Reverses pixel direction every N pixels.

Alternate Direction

|

Alternate map. Reverse makes pixel 1 appear at the far end of the strip.

Some examples of Full Mapping from source DMX512 data ch1 = Full (Pixel 1 Red), ch14 = Full (Pixel 5 Green). Port 1 configured with Pixel Count = 12, Null Pixels = 0, Start Universe = 1, Start Channel = 0.

PORT TAB – DMX512 PORT

Port Operation Mode: DMX-OUT

Port Operation Mode: DMX-IN sACN with sACN Priority 100
DMX512 ports can be individually configured as either DMX-OUT, with automatic dual sACN/Art-Net protocol support, or DMX-IN, with manually selected sACN or Art-Net protocol. When configured as DMX-IN a single Unicast IP address destination may be specified but in the majority of applications leaving this field at 0.0.0.0 is appropriate. Timeout all sources can be used to override default ArtNet defined behavior of holding the last sent or received frame forever.

• DMX-OUT mode : Whenever 2 sources are present and being merged together a 2nd source will always timeout when the stream stops. In DMX-OUT mode if Timeout all sources is unchecked and Hold Last mode selected the output will hold last frame forever. Timeout all sources checked and Failsafe Mode other than Hold Last selected will cause the output to change to Zero, Full or Snapshot Scene.
• DMX-IN mode : An ArtNet or sACN stream is generated upon receiving DMX512 on the port. Timeout all sources checked will cause this stream to end a few seconds after the DMX512 signal stops.

Channel Offset provides simple re-mapping for both DMX-OUT and DMX-IN port configurations. Set to 0 for no re-mapping.

• DMX-OUT mode : Incoming ArtNet or sACN stream(s) are re-mapped so channel 1 is pushed up to channel 1+N. When channel 1+N exceeds 512 the incoming stream channels are ignored/lost.
• DMX-IN mode : Incoming DMX512 is re-mapped so channel 1 is pushed up to channel 1+N on the outgoing ArtNet or sACN stream. When incoming DMX512 channel 1+N exceeds 512 to channels are ignored/lost.

Make changes to the applicable Port settings then click Update. Changes on all port tabs are updated regardless of which tab the Update button is clicked.

RECORDER TAB

Please refer to the eDMX MAX Recorder manual for more information. This functionality is common to all eDMX MAX and LeDMX MAX that include an SD card socket. Backup battery replacement procedure can also be located in that document.

DMX DISPLAY FUNCTION
Select View | DMX Display for a simple DMX512 test utility. To generate an Art-Net output stream click Transmit then select one of the 10 Transmit Options and change Art-Net Universe as applicable. When in Manual mode you can click on any of the channels (represented by small boxes with hexadecimal channel level inside) to set ON level and double click to set zero. The mouse scroll wheel adjusts a channel by a defined increment. Channel number increases left to right, top to bottom and the roaming tool tip provides information about a specific channel. Both the ON level and mouse wheel step can be set by right clicking anywhere within the black display area. Number of channels transmitted and the refresh rate can be adjusted using the applicable sliders adjacent to transmit options.

The DMX Display utility works with any manufacturers Art-Net hardware and can be useful for diagnostics and simple testing of DMX512 fixtures. In Receive mode only Art-Net I broadcast traffic is supported. To display channel data from an eDMX/LeDMX DMX-In port you must configure Broadcast Threshold to 0 otherwise Art-Net messages will be unicast.

NODE REPORT

Node provides a brief status report indicating DMX frame rates, PIXel output rate, SYNC status, SHOW playback selection and RECorder status. Above an LeDMX2 MAX reports Port A at 0fps, Pixel output at 30fps with no synchronization present (Async mode) and the recorder state Idle.

In the example above the recorder status indicates there is No SD card present.

ART-NET NODE NAME
The Art-Net protocol supports device naming which can make larger installations more manageable. Both Short Name (17 characters) and Long Name (63 characters) for an eDMX Device can be edited in the Node Information box.

FACTORY RESET
Factory Reset should only be used when all communication is lost over network and that is typically caused by incorrect network setup rather than a problem with the LeDMX MAX node.

• Level 1 : Factory Reset LeDMX MAX configuration. With the device powered on press and hold FACTORY RESET button for 10 seconds.
• Level 2 : Factory Reset to Bootloader and no firmware. With the device powered off press and hold FACTORY RESET button whilst powering on. Follow procedure to manually load firmware to default IP address or use Find My eDMX application.
• Level 3 : Force ROM Bootloader. Contact support.

eDMX Configuration Factory Reset (Legacy devices) menu is not relevant to LeDMX MAX devices and will not have any effect.

PORTS, MERGING, PRIORITY AND DMX INPUT

DMX512 PORT A AND MERGING
eDMX Products are capable of several advanced merging and stream selection functions. Support for both HTP (Highest Takes Precedence) and LTP (Latest Takes Precedence) merging of 2 sources producing a single DMX512/pixel universe output thus permitting 2 controllers to co-exist for 1 lighting rig. To achieve DMX stream merging simply send 2 Art-Net or sACN streams with the same Universe ID and configure the applicable merge scheme HTP or LTP. If the number of sources exceeds 2 only the first 2 will be processed and all others are dropped. Possible merging sources are:

sACN / E1.31

|

Only sACN sources of the same Priority will be HTP or LTP merged.

PIXEL PORTS AND MERGING
LeDMX MAX supports HTP merging of 2 sources producing a single pixel universe output thus permitting 2 controllers to co-exist for 1 lighting rig. To achieve DMX stream merging simply send 2 Art-Net or sACN streams with the same Universe ID. If the number of sources exceeds 2 only the first 2 will be processed and all others are dropped. Possible merging sources are:

DMX-IN

|

sACN / E1.31

|

Merge external DMX512 source with incoming sACN stream.

SACN / E1.31 PRIORITY
At any time if a higher priority sACN stream is received it will take over control a DMX Out channel / Pixel Universe regardless of other incoming streams or merging. When an sACN stream is stopped gracefully via a stream terminate message the eDMX port / Pixel Universe will immediately revert to whatever other sources are present, otherwise the default stream timeout of 3 seconds applies. If you want to merge 2 sACN streams together they must be of the same priority.

SACN / E1.31 PRIORITY – DMX RECEIVE
When a port is configured for DMX-IN sACN operation the sACN Priority can be set. This permits DMX Inputs to generate sACN multicast or unicast streams with a specific priority.

DMX512 IN – UNICAST / BROADCAST / MULTICAST
When you feed a DMX512 signal into an eDMX Port configured as DMX-IN Art-Net the following will determine Art-Net unicast or broadcast:

1. If Broadcast Threshold = 0 the frame is always broadcast on the IP subnet.
2. If Broadcast Threshold > 0 and number of detected Art-Net II/3/4 devices “subscribed” to that universe is less than the threshold the frame is unicast to each device.
3. If Broadcast Threshold > 0 and the number of detected Art-Net II/3/4 devices “subscribed” to that universe is greater than the threshold the frame is broadcast on the subnet.
4. If Broadcast Threshold > 0 and zero Art-Net II/3/4 devices are “subscribed” to that universe the frame is broadcast on the subnet.
5. If Fixed IP is not 0.0.0.0 the frame is only unicast to the specified IPv4 address.

As you can see there are multiple ways broadcast could occur. The implementation is done like this to ensure compatibility with mixed Art-Net I/II/3/4 device networks but still permit unicast when Art-Net II/3/4 devices are used exclusively. For DMX-IN sACN multicast frames will be generated when Fixed IP is 0.0.0.0 otherwise frames are unicast to the specified destination.

COMPATIBLE SOFTWARE

Art-Net/sACN and DMX512 are the most commonly used lighting control protocols with roots in simple theatrical light dimming. These days almost any lighting or stage effect equipment may be controlled using DMX512 including LED pixels. The DMXking LeDMX2 MAX unit is a 2 Pixel Output + 1 DMX512 sACN/Art-Net device designed for use with computer-based show control and effect software.  Check the following page for a short list of compatible software: http://dmxking.com/control-software

WHERE DO I BUY LED PIXELS

There are many sources for LED pixels in strip and other formats. Pretty much all of it comes out of China and it can be more cost effective to source through sites such as Aliexpress which provide individual item sales without much effort. Try these Aliexpress stores or direct from a manufacturer:

• https://kinggreen.aliexpress.com/store/713947
• https://www.aliexpress.com/store/701799

• Q: Does DMXking recommend any particular type of pixels or control ICs?
  A: We highly recommend APA102/SK9822 pixels because they have a higher clocking rate and an additional 5bit master current control. This really helps with smooth fades at reduced Master Level.

• Q: What is DMX512P? Is this DMX512?
  A: Yes and No. Actually, more No than Yes. Someone thought it would be a good idea to use DMX512 signaling for pixel control but it really makes no sense and creates confusion because it’s not a differential signal like real DMX512. Connect DMX512P pixels to the Pixel Ports only so the signal levels are appropriate.

• Q: How big should my power supply be?
  A: It depends on the pixel count, output intensity, and how many pixels will be lit simultaneously. Often power supplies are over sized when calculations are done assuming all pixels might be on at full intensity. There is no straight answer and per pixel current consumption should be ascertained from the product datasheet.

• Q: Why do my pixels start going pink instead of white further along the strip?
  A: What’s happening is the power supply voltage is dropping and generally blue LEDs will drop in current first since they have the highest forward voltage. This is simply V=IR and different strips will exhibit different results because their conductor resistance might be higher/lower. By injecting power again (from the same power supply or another power supply) along the strip at intervals it is possible to mitigate the voltage drop effects. Higher voltage strips/pixels (12V or 24V) are usually less susceptible to color fade issues.

• Q: What happened to the 5V and 12-24V LeDMX4 PRO versions?
  A: These have been merged together in the new eDMX MAX product so there is no longer a supply option that works from 5V up to 24Vdc.

• Q: Is it possible to control pixel outputs from DMX512 rather than Art-Net/sACN over the network?
  A: Yes but there’s only 1 DMX512 port and thus 1 DMX Universe available so you’re constrained in how many pixels can be controlled. Of course using Full Mapping mode with >1 Pixel Group size it’s possible to stretch that 1 universe a little further. Just configure Port A as DMX-In sACN on the same universe you’ve configured a pixel output.

• Q: I’m use WS2813 pixels with dual signal wires. What should I connect to the LeDMX4 PRO pixel port?
  A: Only the DATA IN wire from the pixel strip should be connect to DA on the LeDMX4 PRO. Do not connect the DATA OUT return wire to anything.

• Q: The power supply I purchased has exposed AC input terminals. Is this safe?
  A: No. Unless you are suitably qualified please defer all AC mains wiring to applicable professionals. Safety first.

• Q: My question doesn’t appear here.
  A: Ask your distributor for technical support. Maybe it’ll appear in the next user manual too.
