Quick answer: To install a NovaStar MSD300 LED sending card in a VDWALL LVP615S video processor, disconnect the processor from AC power, remove the rear slot screws and cover plates, secure the sending card to the removable bracket, connect its power cable, reinstall the bracket, and then run a controlled power-on test. The complete procedure is below.
This guide explains the physical installation shown in our video and adds the checks needed before and after assembly. It is intended for LED display technicians working with the VDWALL LVP615S and a compatible LED sending card. The demonstration uses a NovaStar MSD300.
Before You Install the Sending Card
Prepare the processor on a clean, stable, static-safe work surface. You will need the compatible sending card, its internal power cable, and a screwdriver that fits the LVP615S rear-panel screws.
Safety: Shut down the LVP615S, unplug the AC power cable, and wait before opening the chassis. Use appropriate electrostatic-discharge protection and handle the sending card only by its edges. If you are not qualified to service powered electronic equipment, ask a trained technician to perform the installation.
Compatibility checklist
- Confirm that the sending card model is supported by your LED control system.
- Check that the card fits the LVP615S internal sending-card bracket and connector position.
- Inspect the sending card, power lead, slot, and mounting hardware for damage.
- Keep all screws, hexagonal studs, and cover plates together for reassembly.
- Do not connect the processor to power while the chassis is open.
How to Install a NovaStar MSD300 in the VDWALL LVP615S
- Disconnect all power. Turn off the VDWALL LVP615S and remove the AC cable. Disconnect signal cables if they restrict access to the rear panel.
- Remove the two retaining screws. Unscrew the two fasteners that hold the sending-card bracket or rear slot assembly in place.
- Remove the required cover plates. Take out at least two rear slot plates to create enough space for the card and its output connectors. Store the plates and screws safely.
- Remove the hexagonal studs and metal retaining plate. Keep the hardware in its original order so it can be reinstalled correctly.
- Seat the sending card in the bracket. Hold the card by its edges, align it with the card slot, and press it straight into position. Do not force the connector or bend the circuit board.
- Secure the sending card. Reinstall and tighten the hexagonal studs. The card should be firmly supported, with its connectors aligned with the rear opening.
- Connect the card power cable. Attach the internal power lead to the sending card in the correct orientation. Verify that the connector is fully seated and that the cable will not be pinched.
- Return the bracket to the processor. Slide the completed card-slot assembly back into the LVP615S carefully. Keep cables clear of sharp edges and moving parts.
- Tighten the rear screws. Reinstall the two retaining screws and confirm that the assembly sits flush with the rear panel.
- Perform a power-on test. Reconnect power and turn on the processor. Check that the sending-card status lights operate normally, then verify signal output to the LED display.
Post-Installation Checks
| Check | Expected result |
|---|---|
| Mechanical fit | The card and bracket are secure, level, and flush with the rear panel. |
| Power connection | The internal power cable is fully seated and not pinched. |
| Status LEDs | The sending-card indicators show normal power and operating status for the installed model. |
| Signal path | The processor output reaches the sending card and the LED display receives data. |
| Cooling | No cable or removed part blocks airflow inside the processor. |
Troubleshooting After Installation
The sending card does not power on
Turn the processor off and unplug it. Recheck the internal power connector, its orientation, and the cable condition. Confirm that the card is seated evenly and that no mounting hardware is causing a short circuit.
The card powers on but the LED screen has no image
Check the processor output settings, sending-card configuration, Ethernet/data cables, receiving-card mapping, and LED control software. Physical installation alone does not load the correct screen configuration.
The bracket will not slide back into the LVP615S
Do not force it. Remove the assembly and check the card alignment, rear connector position, cable routing, and placement of the metal retaining plate and hexagonal studs.
The status light is abnormal
Power down immediately if you notice overheating, an unusual smell, visible damage, or a persistent fault indication. Recheck the installation and consult the documentation for your exact sending-card model.

Frequently Asked Questions
Can the VDWALL LVP615S hold a NovaStar MSD300 sending card?
Yes. The installation demonstrated here uses a NovaStar MSD300 in the LVP615S internal sending-card slot. Confirm the exact card revision, mounting arrangement, and power connector before installation.
Do I need software after installing the sending card?
Usually, yes. After the hardware is installed, the sending card and receiving cards must use the correct LED display configuration. Back up the existing configuration before making changes.
Can I install a different LED sending card?
Only use a card that is mechanically and electrically compatible with the processor and your LED control system. Card size, connector position, power requirements, and software support must all match.
Should I change the LVP615S settings before opening the chassis?
The physical installation does not normally require a front-panel setting change, but you should record the current processor and LED screen configuration before service.
