6.2 Saving the DMX signal
If you want to use the projector without a console is possible to memorize a DMX address
removing the DMX signal when the projector is on, to keep the current values at the time
when the signal is removed
6.1 Control signal connection by XLR5 plugs
The digital control signal is transmitted to the projector via two pole cable screened
according to the International standards for the transmission of DMX 512 data. The
connection must be serial, by connecting the single output cable from the Pixel in the
RegoPixel’s entrance “A”, which will be connected to a console. The connectors provided
with the Pixel are IP rating, ensuring protection against dust and water.
In order to maintain this gradation they may only be connected to other connectors with
IP rating.

7.1 DMX addressing
Every Pixel uses 4 address channels for its complete functioning and it is controlled with a
DMX512 signal. The assignment of the DMX channel is automatically done by the Pixel at
the moment it will be connected to RegoPixel; if you connect more Pixels, the signal will
also be set automatically but with a “cascade” method, then the first to receive the signal
will be the Pixel # 1 then # 2, and so on.
7. Turning on the projector
After having followed the preceding steps described, proceed with the power supply and
turn on the projector connecting it to the mains power.

10. RegoPixel
14
RegoPixel is DMX/RDM system with a power supply of 48 Vdc. It is not neccessary to
polarize the conductors, thanks to this the cabling will be easier. The maximum number
of connectable is 32 and a maximum of 8 byte of datas, while the maximum total charge
allowed is 500W @ 24 Vdc. RegoPixel is compatible with ArtNet systems where it cam be
used as node to a DMX universe, or it can be controlled through DMX remaining compatible
with RDM, allowing all the possible action of setting DMX channels. RegoPixel is seen as a
transparent object, it means that the signal goes directly to the single Pixel. RegoPixel can
be used as a DMX recorder too, thanks to the SD card dadicated slot you can memorize one
or more shows. The RegoPixel comunication is a Time Slot type where RegoPixel is the
master that provides power and DMX to the modules.
10.1 DMX In & Out Mode
RegoPixel can works as DMX receiver (DMX In Mode) or DMX generator (DMX Out Mode).
The modality is selected through Ethernet command using the eSuite or JArtNet software.
The default IP is 10.0.0.190. The status and the modality of functioning are indicated by the
5 LEDs, described after. When RegoPixel is in DMX In Mode, the device respond to all the
standard RDM command (basic DMX address, DMX address of the single RegoPixel, etc. etc.).
If Play of a show registered on the SD card will be started, the device become temporarily a
DMX generator. If the device is in DMX Out Mode and you don’t have an Ethernet connection,
to bring it back in DMX In Mode, apply a DMX signal in the entrance and turn on the device.

10.2 Input description
The device has 4 digital input (IN1 - IN4) whose functionality is described below.
• Input IN1-IN2: Run prerecordered Shows on SD card, in according to table below.
0 = input false 1 = input true:
IN2 IN1 Function
0 0 Stop
0 1 Play show n.1
1 0 Play show n.2
1 1 Play show n.3
• IN3: Reserved for future use
• IN4: Command Play Stop / Play Start / Record Stop / Record Start on single button:
The input IN4 is useful in case you wish to record a show in one of the three available
position. A short press produces the stop of an eventual Play/Record in progress. If the
device is already in Stop, produces the start of the selected show on the inputs IN1 and
IN2. If the inputs are both at rest, will start the show # 1 or the last show activated via
Ethernet (1-999).
To launch a Play is not necessary to act on IN4, because the IN1 and IN2 perform this
automatically when they change their status.
The input’s functions don’t prevent the regular functioning of the commands Play/Record
imparted by eSuite or JArtNet. For this purpose, they act only on change in status.
You can leave unconnected inputs and also achieve operation of the Play/Record remotely
via Ethernet, despite IN1 and IN2 are at 0 (condition which normally corresponds to Stop).
The number of shows selected remotely via ArtNet (Ethernet 1-999) remains operative
and you can run it in Play also through IN4 short activation. It is only lifted by acting on
IN1 and IN2, because they select the show 1-3 according to their state.
The status of the IN1 and IN2 input can be altered in all the combinations; you don’t need
to pass by the Stop to activate the Play in a different show. The device provides to close
preventively the file of an eventual show in progress, before to launch the new one.
In case you start the Play through an Ethernet command, the device remember the
first status in case of the power supply’s shutdown and it performs the show eventually
previously activated; if the IN1 and IN2 entrance are different by 0, it will be activated the
show slected by them.

10.3 Recording a show
To record a show in the SD card, follow the instruction below:
• Select the number of the show that you wish to record (1-3) acting on IN1 and IN2;
• If a show is present (so it is started in Play), stop it activating IN4 briefly;
• Give the signal to record on DMX In or ArtNet;
• Start the recording IN4 activating IN4 for more than 2 seconds;
• To terminate the recording, activate IN4 briefly.
10.4 Signaling LED
The yellow/red LEDs, on the Ethernet connector side, indicate the status of the Ethernet
link (ArtNet):
• Both off = unconnected cable
• Red on/flashing = link at 10mbit LED 9
• Yellow on/flashing = link at 100mbit LED 10
LED status device
LED 3 = Green
LED 6 = Red
LED 7 = Yellow
*see the LED’s table at page 17
At the start you’ll see the LED 6 Red will blink during the bootloader loading, than the
LED 7 Yellow, that indicates the direct DMX In fase, that can revoke an eventual DMX Out
Mode status. At last, LED 3 Green or LED 6 Red will stay ON depending on the operating
condition, described below:
• LED 3 Green ON = DMX Input Mode;
• LED 3 Green blinking = DMX in entrance;
• LED 6 Red ON = DMX Output Mode;
• LED 6 Red blinking = ArtNet in entrance;
If ArtNet is present but the device is in DMX In Mode, you will se the Green ON and Red
blinking.
During the functioning, the Yellow LED will turn ON if the first channel DMX/ArtNet
is≥128(receivingmonitor).
LED signaling logic for the player:
• LED 3 Green slow blink = Play (SC card)
• LED 3 Green very slow blink = automatic Show
• LED 6 Red slow blink = Record; if DMX input is receiving data frames, the Green LED
will flash at 25%.
If Play/Record is in pause, the respective LED will blink with duty 20% (pratically a slow
blink).
If the SD card give mistake, the Red LED will flash slow with a duty of 90% for three
seconds.
