NovaStar DIS-300 is a Gigabit Ethernet port distributor built for LED display systems. It accepts up to 2 Gigabit Ethernet inputs and distributes the signal to 8 Gigabit Ethernet outputs, switching automatically between the 1 in 8 out and 2 in 4 out working modes. Every RJ45 port can be adjusted independently and supports reading back parameters from the receiving card, so one sending device can drive several small and medium-sized LED screens at the same time without extra switches.

Why the DIS-300 Is Used in Multi-Screen LED Projects
- 2× Gigabit Ethernet inputs and 8× Gigabit Ethernet outputs — a single DIS-300 replaces several Ethernet switches in one LED display system.
- Two working modes with automatic switching — 1 in 8 out for one large screen, 2 in 4 out for two independent screens.
- Up to 1,300,000 pixels of total input capacity in 2 in 4 out mode (650,000 pixels per input port).
- 650,000 pixels per output port — enough capacity for a full HD-class LED screen on a single RJ45 cable run.
- Receiving card read-back — parameter read-back from the scan board lets you configure and check the display from the sending end.
- Independent RJ45 port adjustment — each port is configured on its own, which keeps multi-screen and rental setups flexible.
- Fanless, low-power chassis — 20 W rated power consumption, CE and RoHS certified, 1.05 kg metal housing.
NovaStar DIS-300 Working Modes: 1 In 8 Out and 2 In 4 Out
| Working mode | Input ports used | Output ports | Total input capacity | Typical application |
|---|---|---|---|---|
| 1 in 8 out | Port A | A1 – A8 | Up to 650,000 pixels | One large LED screen fed by a single sending port |
| 2 in 4 out | Port A + Port B | A1 – A4 and B1 – B4 | Up to 1,300,000 pixels | Two independent LED screens or one very large display |
The DIS-300 detects the connection automatically and changes function by itself, so there is no mode switch to set. Each RJ45 port supports independent adjustment and data read-back from the receiving card.
Ethernet Port Layout and Capacity

| Connector type | Port name | Description |
|---|---|---|
| Input | A, B | Gigabit Ethernet ports, input capacity of each up to 650,000 pixels. Combined capacity up to 1,300,000 pixels in 2 in 4 out mode. |
| Output | A1 – A8 B1 – B4 | Gigabit Ethernet ports, output capacity of each up to 650,000 pixels. |
Port mapping: in 1 in 8 out mode, port A feeds outputs A1 – A8. In 2 in 4 out mode, port A feeds outputs A1 – A4 and port B feeds outputs B1 – B4.

What’s in the Box
- 1× NovaStar DIS-300 Ethernet Port Distributor
- 1× power cord
- Packing box: 390.0 mm × 250.0 mm × 85.0 mm; accessory box: 295.0 mm × 83.0 mm × 35.0 mm
Typical Applications
- Fixed installations with multiple small and medium-sized LED displays
- Banks, shopping malls and securities company information screens
- Rental and stage projects where one controller must feed several screens
- Super large LED screens that need the signal split across many RJ45 runs
The DIS-300 is normally installed between an LED controller card and the receiving cards of the display. For long-distance runs, pair it with a fibre converter such as the NovaStar CVT310 multi-mode optic fibre converter or the NovaStar CVT320 single-mode optic fibre converter. The ZDEC A81DS-01 distributing controller is a comparable alternative from another brand.
Frequently Asked Questions About the NovaStar DIS-300
What is the NovaStar DIS-300 used for?
The NovaStar DIS-300 is an Ethernet port distributor for LED display systems. It takes the Gigabit Ethernet signal from a sending device and splits it to up to 8 outputs, so one controller can feed several small or medium-sized LED screens, or a very large screen that needs multiple data runs.
How many Ethernet ports does the DIS-300 have?
The DIS-300 has 2 Gigabit Ethernet input ports (A and B) and 8 Gigabit Ethernet output ports (A1 – A8 and B1 – B4), giving 10 RJ45 ports in total. Each port supports up to 650,000 pixels.
What is the difference between 1 in 8 out and 2 in 4 out mode?
In 1 in 8 out mode, input port A is distributed to all eight outputs A1 – A8 and the total input capacity is 650,000 pixels. In 2 in 4 out mode, input A feeds outputs A1 – A4 and input B feeds outputs B1 – B4, raising the total input capacity to 1,300,000 pixels, which is useful for two separate screens or one very large display. The DIS-300 switches between the two modes automatically.
How many pixels can one DIS-300 handle?
Each Gigabit Ethernet port carries up to 650,000 pixels. With both inputs active in 2 in 4 out mode the DIS-300 handles up to 1,300,000 pixels in total.
Does the DIS-300 support receiving card parameter read-back?
Yes. The DIS-300 can read parameters back from the scan board (receiving card), and each RJ45 port can be adjusted independently, which simplifies setup and troubleshooting on multi-screen installations.
What is the price of the NovaStar DIS-300 and is it in stock?
The current price and live stock level are shown at the top of this page. The unit ships worldwide from our warehouse, and bulk pricing is available for distributors and project integrators, so contact us for a quotation.
