- Yellow, green, and red light colors with flashing, burst-flashing, and steady modes
- Separate audible and visual warning output
- DC 9-30 V supply
- Panel or bracket mounting
5. Integration notes
The supplied parameter table confirms RS485 control, DC 9-30 V supply, three light colors, three light modes, 30 mm mounting-hole diameter, 52 mm light-body diameter, PC lampshade material, a -20°C to 60°C operating temperature, and panel or bracket mounting. It lists both a custom RS485 protocol option and a standard Modbus protocol option. The Modbus reference confirms Modbus RTU at 9600 bit/s and shows a frame containing the device address, function code, start address, data, and CRC-L/CRC-H bytes. Use the protocol and delivered configuration that match the ordered unit.
The extended standard Modbus reference also lists commands for looping all tracks, stopping playback, looping a folder, random playback, looping the current track, setting the device address (0xC0), independently controlling warning lamp D1 (0xC2), and querying the current track, playback status, volume, file count, and sound/light status with function 03H. These commands apply to the standard Modbus profile only; confirm the delivered protocol option and response definition before integration.
Do not apply the Y811-52V or Y811-75AV register map to Y811-52AV without confirmation.
6. Confirmation items
