The CDF9928A-16 Navigation Light Controller is a new type of navigation light controller specially designed for yachts. The controller has functions such as test light, dimming, silencing, filament break flashing alarm, independent alarm indicator light, independent alarm silencing and RS485 communication, and can directly control no more than 16路DC24V-60W navigation lights (signal lights) on/off.
This Chinese manual describes the CDF9928A-16 navigation light controller, a controller designed for yachts and also intended for installation on ships with control consoles. It covers the controller's test lamp, dimming, silence, broken-filament flashing alarm, independent alarm indication, and RS485 communication functions.
The controller uses a microcontroller and bus control, with a mounting base, receiver board, and control display board. The manual provides main performance data, operating instructions, installation and testing notes, maintenance precautions, and a wiring diagram. This manual is written in Chinese.

The manual lists a DC24/12V ±10% supply with power greater than 180 W.
The main performance section lists 11 control channels, with each 24 V lamp rated at no more than 60 W.
The corresponding indicator changes from steady on to flashing, and the buzzer gives an audible and visual filament-break alarm; pressing the silence button stops the buzzer while the indicator keeps flashing.
The manual says the microcontroller may have hung due to strong interference; turn the power off and then on again.
