LED Display Signal Distribution
The ZDEC A81DS-01 is a signal distribution controller for LED display systems. It copies a transmitting card’s signal to multiple output channels, making it relevant when a display installation needs signal distribution from an existing transmitting card.
Specifications and Input Modes
| Parameter | Specification |
|---|---|
| Model | A81DS-01 |
| Brand | ZDEC |
| Function | Copies the transmitting card signal to multiple output channels |
| Signal technology | Gigahertz technique |
| Power supply | AC power supported |
| A/B independent input | “1 divided into 8” mode |
| A/B synchronous input | “2 divided into 4” mode |
Choosing the A/B Input Mode
The input arrangement determines the distribution mode: independent A/B input supports “1 divided into 8”, while synchronous A/B input supports “2 divided into 4”. Match the intended wiring layout to the required mode before installation.
When replacing an existing distributor, check its model label, transmitting card and connector layout. Confirm the AC input rating from the unit label before connecting power; a numeric voltage range is not specified here.
