Configuration and Monitoring
Match the module driver and connector pin assignment before installing a replacement card. The listed 96K capacity is a total pixel rating; confirm the supported width, height and scan configuration for the cabinet.
Monitoring functions depend on the corresponding sensors and cabinet connections. The product description also lists power pins at each port for supply from the LED panel; check the specified wiring before using this arrangement.
Frequently Asked Questions
How many RGB data groups does the D90-A4S output?
It provides 24 RGB output groups. This is a data-group count, not a claim of 24 physical connectors.
What is the listed pixel capacity per D90-A4S?
The product lists 96K pixels per receiving card. Confirm the required cabinet dimensions and scan mode before configuration.
Can I read the receiving-card configuration back?
Yes. Parameter readback is a listed function and can help retain the existing configuration during maintenance.
