DIS-300 Ethernet Port Distributor
The NovaStar DIS-300 distributes LED display control signals across multiple small or medium-sized screens. Its two Gigabit Ethernet inputs and eight outputs support rental and fixed installations in locations such as shops, banks and securities offices.
| Parameter | Specification |
|---|---|
| Ethernet connections | 2 × Gigabit inputs; 8 × Gigabit outputs |
| 1 in 8 out mode | Input A routes to outputs A1–A8 |
| 2 in 4 out mode | Input A routes to A1–A4; input B routes to B1–B4 |
| Input capacity | Up to 650,000 pixels per input; up to 1,300,000 total in 2 in 4 out mode |
| Output capacity | Up to 650,000 pixels per output |
| Receiving-card data | Readback supported |
| Power input | AC 100–240 V, 50/60 Hz, 0.6 A |
| Rated power consumption | 20 W |
| Dimensions / net weight | 356.5 × 173.2 × 47.5 mm / 1.05 kg |
| Operating environment | −20°C to +60°C; 0–90% RH, non-condensing |
Choosing the Distribution Mode
Use 1 in 8 out mode when the signal entering input A must reach all eight output branches. Use 2 in 4 out mode for two input signals, each feeding its own group of four outputs. In the second mode, the input limit is 1,300,000 pixels across both inputs.
Eight output connectors do not increase the source signal capacity eightfold. Plan the screen arrangement around the selected mode and the per-input and per-output limits. The device distributes LED control data; the specification does not describe ordinary computer-network switching.
| Parameter | Specification |
|---|---|
| Green running indicator: two flashes per second | The input port is connected to the system |
| Green running indicator: continuously on | The input port is not connected to the system |
| Red power indicator: continuously on | Power supply is normal |
Receiving-card data readback is supported for system checks. If the green indicator remains continuously on, check the input connection rather than assuming that a steady light confirms normal signal access.
Frequently Asked Questions
What is the difference between the two DIS-300 modes?
In 1 in 8 out mode, input A feeds A1–A8. In 2 in 4 out mode, input A feeds A1–A4 and input B feeds B1–B4.
How many pixels can DIS-300 accept?
Each input supports up to 650,000 pixels. Total input capacity reaches 1,300,000 pixels in 2 in 4 out mode.
Do eight outputs provide eight times the input capacity?
No. The output ports distribute the input signals according to the selected routing mode. Each output is rated for up to 650,000 pixels, while input capacity remains subject to the stated input limits.
What does a steady green DIS-300 light mean?
The specification says the input port has not connected to the system. Two green flashes per second indicate that the input port has connected; a steady red power light indicates normal power.
Can DIS-300 read data back from a receiving card?
Yes. Receiving-card data readback is a listed feature of the DIS-300.
