What is the NovaStar DH3208 receiving card?
The NovaStar DH3208 is made for LED cabinets that use its eight onboard HUB320 connectors. It receives the image from the controller and sends it straight to the cabinet’s modules, so the cabinet can use one integrated board instead of a separate receiving card and hub board.
It is a good fit when the cabinet already has a DH3208, or when a cabinet maker has designed the module ribbons and mounting around this exact board. For a replacement order, the board layout matters more than a similar pixel number: the wrong connector order can turn a simple spare into a cabinet rework.
For a new cabinet, order the DH3208 only after the cabinet maker confirms a DH3208-specific layout, the driver-IC type and the module data path. It is not a general substitute for every card with HUB320 connectors. If the cabinet expects a separate hub board or another connector map, use the card that matches that cabinet instead of adding adapters or reworking the module ribbons.
DH3208 key features
One integrated board for the matching cabinet
The eight HUB320 connectors link the card directly to the cabinet modules. For a cabinet built around DH3208, that can simplify the internal layout and make a like-for-like spare easier to service later. The benefit depends on the cabinet using this exact connector arrangement.
Less guesswork when one cabinet misbehaves
Mapping can show the receiving-card number and Ethernet port on the cabinet. Temperature, voltage and Ethernet bit-error checks help narrow a problem to one cabinet, cable or power path before a technician starts replacing good parts.
A cleaner result after a module repair
Color Management, 18bit+, pixel-level calibration and seam adjustment can help a compatible cabinet blend back into the wall after a module repair or at low brightness. They work with the right cabinet data; they cannot make a mismatched module look like the original one.
A stored image and backup path when the wall is built for them
A pre-stored image can appear at startup or when video or Ethernet is lost. The DH3208 also supports loop backup when the controller and cabinet are wired with main and backup lines. A replacement card does not create that redundancy in a wall that was never wired for it.
NovaStar DH3208 specifications
These figures identify the board and set the first cabinet-fit limits. The driver-IC condition changes the maximum image area, so read the next capacity section before planning a one-card cabinet.

DH3208 HUB320 connectors and cabinet wiring
The most important DH3208 question is not only how many pixels it can carry. Its eight HUB320 connectors define where the module ribbons go and the output order the cabinet expects. A different receiving card may fit in the cabinet shell yet send data to the wrong module positions.
Before ordering a spare, compare the old board’s DH3208 label, connector positions, module ribbon order and mounting holes. If the old board is unavailable, send clear cabinet-interior photos and the saved configuration so the replacement can be checked before it ships.
DH3208 load capacity for PWM and common driver ICs
Capacity answers a simple order question: can one DH3208 serve this cabinet, or does the cabinet need a different layout? With PWM driver ICs, one card can carry up to 512 × 512 pixels at 60 Hz. With common driver ICs, the limit is 512 × 384. The larger PWM number does not apply to a common-driver cabinet.
| Cabinet electronics | Maximum per DH3208 | What to check next |
|---|---|---|
| PWM driver ICs | 512 × 512 at 60 Hz | Confirm the 32-group data path, scan and exact HUB320 layout. |
| Common driver ICs | 512 × 384 at 60 Hz | A taller 512-wide cabinet needs another card or a different cabinet design. |
Capacity is only the first filter. The module scan, 32 parallel RGB groups, connector order and saved cabinet configuration still need to match the actual cabinet.
Replacing a DH3208 without losing the cabinet map
Before removing a working card, use NovaLCT to save the receiving-card program and cabinet parameters. These two files preserve how this cabinet works: one covers the board program, the other stores the cabinet’s scan, wiring and pixel map.
Then compare the DH3208 label, HUB320 layout, module ribbons and mounting pattern. Test the saved configuration on one cabinet before applying it across the wall. This small check helps avoid a replacement that powers up but shows a scrambled image.
DH3208 datasheet, firmware and NovaLCT
Use the DH3208 datasheet to confirm the board dimensions, connector arrangement and load condition. For a service replacement, save the working program and cabinet parameters in NovaLCT first. Choose firmware only after the board and module electronics have been verified; a newer file is not automatically the right file for a working cabinet.
NovaStar DH3208 FAQ
What does the DH3208 receiving card do?
It receives the controller’s assigned image data and sends it to the LED modules in a compatible cabinet through its eight HUB320 connectors.
Does DH3208 need a separate hub board?
Its onboard HUB320 connectors can eliminate a separate hub board only in a cabinet built around this exact board and connector order.
What is DH3208 loading capacity?
At 60 Hz, it supports up to 512 × 512 with PWM driver ICs or 512 × 384 with common driver ICs. The scan, data groups and wiring must also match.
Can a different DH card replace DH3208?
Not as an automatic swap. Confirm the board dimensions, HUB320 connector layout, module ribbons, driver IC, scan and saved cabinet parameters first.
What should I save before replacing a DH3208?
Save the working receiving-card program and cabinet parameters in NovaLCT. They preserve different parts of the cabinet setup.
Can DH3208 help diagnose a cable fault?
Mapping, temperature and voltage monitoring, and Ethernet bit-error detection can help locate the affected cabinet and signal path in a compatible system.
Does a replacement DH3208 add redundancy?
No. Loop backup works only when the controller and cabinet run have been wired with the main and backup paths.
Can I request DH3208 volume pricing or Net 30 terms?
Yes. Send the cabinet count and spare quantity for volume pricing or eligible Net 30 terms. Include the cabinet model if the order is a replacement.
How is DH3208 warranty coverage handled?
Cards supplied through our authorized US NovaStar channel include three years of serial-tracked manufacturer coverage.
