Screw the two down bolts of the DXBS21 to the ground beam GXHGB01 / GXHGB02 throught the back frame DXBSC.

Install the cabinet.

Screw the two top bolts of the DXBS21 to the cabinet.

To mount the cabinets horizontally, use the specific side locks by push and turning the locking lever.

Complete the line for then assemble the next line.

To mount the cabinets vertically, match the pins of the cabinet below with the holes of the cabinet you are mounting.

To lock the cabinets vertically, use the upward lock by push and turning the locking lever.

Install the DXBSC back plate between cabinets in case of complex installations.

Finally, repeat all the previous steps to complete the Video Wall.

FLY BAR HANGING SYSTEM

Fasten the fly GXHGB01 / GXHGB02 fly bars at the structure.

Install the cabinet on the flybars by matching the pins to the holes in the bars.

To lock the cabinets vertically, use the upward lock by push and turning the locking lever.

Pay attention that the cabinets are well aligned and make sure there are no steps between panels horizontally and on the front of the panels.

Use the specific side locks by push and turning the locking lever, to hook the cabinets horizontally

Install the DXXJ back plate between cabinets and Flybar.

Finally, fasten other cabinets sequentially from top to bottom and from middle to both sides (the number of cabinets in vertical direction shall not be more than 10 cabinets, while i in the horizontal direction is not restricted)

CONNECTION TO THE MAINS SUPPLY

Each cabinet has an IN and OUT power connection (powercon true or powercon). It’s possible to connect in chain many cabinets. To design the power cabling, it’s necessary to know the max power con-sumption for each panel. It’s possible to see this info in the specifications of the product
Examples:

WARNING: For protection from electric shock, the panel must be earthed!
The product is equipped with auto-switching power supply that automatically adjusts to any 50-60Hz AC power source from 110-230 Volts.
If you need to install a power plug on the power cable to allow connection to power outlets, install a grounding-type (earthed) plug, following the plug manufacturer’s instructions. If you have any doubts about proper installation, consult a qualified electrician.
The maximum power consumption of single panel is 120W.

START UP

CONNECT AND DISCONNECT POWER FROM THE PRODUCT
To apply and disconnect power to the product:

• Check that the product is installed and secured as indicated in the Safety Information’s, and that personal safety will not be put at risk when the fixture lights up.
• Connect the power connector into the Mains input socket (100-240 VAC-50/60 Hz).
• The product is then ready for its operations and can be controlled through the available input signals on board.
• To disconnect power from the product, disconnect the Mains from the socket.

DATA CONNECTION

DATA CABLING
Each cabinet has an IN and OUT data connection (RJ45). Each data output of a Novastar processor, can manage a max of 650.000 pixels. To design the cabling of data, it’s necessary to know the resolution of each cabinet.
Examples:

Product| Cabinet Total Pixels| Max number of cabinets for a data line
---|---|---
SIGMA X26 series| (192×192 pixels) 36.864| 17
GAMMA X29 series| (168×168 pixels) 28.224| 23
SIGMA X39 series X1| (128×128 pixels) 16.384| 39
SIGMA X39 series X2| (128×256 pixels) 32.768| 19
GAMMA X48 series X1| (104×104 pixels) 10.816| 60
GAMMA X48 series X2| (104×208 pixels) 21.632| 30
KAPPA X26 series| (192×192 pixels) 36.864| 17

NOTE: it’s suggested to distribute the signal as evenly as possible between the various signal lines.
NOTE: it’s necessary to complete a row or a column with a data chain. It’s not possible to connect half of a row or a column on a data chain.

MAIN AND BACKUP DATA LINE
For all Prolights led screen cabinet it’s possible to install a MAIN data line and a BACKUP data line. This allows to see image on led screen in case of MAIN failure. MAIN and BACKUP need to be assigned from the PC software to the outputs of the processor.
MAIN data cable comes from the output of the processor to the last cabinet of the chain.
BACKUP data cable come from the output of the last cabinet of the chain to the output of the processor.
NOTE: it’s always suggested to use different processor for MAIN line and BACKUP line

LED DISPLAY CONTROL SETTING

SYSTEM CONFIGURATION
Novastar processor is the sending card that sends signal to cabinets. Each cabinet has a receiving card mounted in. Novastar processor has a different number of DATA output depending from the product version. Each DATA output can manage a max number of 650.000 pixels.

NOTE: 650.000 it’s only a reference number considered for a settings of 60Hz and 8 bit for color.The max number of pixels is related to different values such as bit rate, cables quality and cables lenght.
The type and the number of Novastar processor need to be selected in relation to:

• total led screen dimensions
• total led screen resolution
• kind of application (fixed or rental)
• scaling needed or not
• input video source

Equipment in need to configure the led screen:

• Windows PC
• USB cable
• Nova LCT software

NOTE: PRO user can utilize the software SMARTLCT to configure more complex led screen. It’s pos-sible to see user manual on Novastar web site download page https://www.novastar.tech/downloads/

RESOLUTION MANAGEMENT
The have the best result in terms of resolution on your led screen is to respect the chain of input and output resolution between video source and led screen.
The more the rate between led screen pixels and sending card resolution is near to 1:1, the more the result is better.
Video resolution need to be defined during led screen design

• PC output resolution can be set in PC settings
• Led screen resolution is the phisical number of pixels in the led screen as shown at page 3
• Sending card resolution can be s et on NOVALCT in Screen Configuration – Sending Card

Example:

Video Resolution

Pc output resolution Sending card resolution

| HD 1920×1080 (2.073.600 pixels)

NOTE: HD resolution can be used in this case because is very similar to the native one

Pixel rate| 1:1,125 (2.073.600/1.843.200)
