NovaStar receiving cards & firmware that support the Decode595 scan/decode chip
The Decode595 is a row/scan decode chip, not a pixel driver IC — it handles the panel's multiplexed scan addressing. Each NovaStar receiving-card firmware version bundles support for a specific group of pixel driver ICs and a specific group of decode/scan chips. Your panel needs a compatible chip from both groups, so flash the version that lists the Decode595 below and your panel's driver IC.
⚠️ Don't upgrade unless you have a reason to. Receiving-card firmware is not like a controller update that adds features — a higher number just means a different driver-IC group. If your screen works, leave it alone; only re-flash to match a different driver IC.

Frequently asked questions
What is the Decode595 chip?
The Decode595 is a row/scan decode chip used on LED display modules. It is not a pixel driver IC — instead of setting pixel grayscale, it handles the panel's multiplexed scan addressing (selecting which row group is lit). A scan LED panel uses a decode/scan chip like this together with a pixel driver IC.
Does NovaStar support the Decode595?
Yes — the Decode595 is in NovaStar's recognized decode/scan-chip library. Because a firmware version supports a specific group of driver ICs paired with a specific group of decode chips, exact support depends on your receiving card and firmware version. Upload your config to our RCFGX viewer to confirm, or call 321-747-3220.
How do I find out which driver IC and decode chip my LED panel uses?
Open your receiving card configuration file (.rcfgx) — it records both the pixel driver IC and the scan/decode chip plus the firmware version. Our free online RCFGX viewer reads this for you without installing NovaLCT.
