NED200 Parking LED Display Controller with TCP/IP RS485 MQTT Wiegand Relay HUB75 HUB08 for Parking Guidance and Access Control Systems

The NED200 is a comprehensive LED display and system integration controller designed for smart parking, parking guidance, vehicle access control, LPR entrance systems, LED information displays, and customized parking terminals.

Unlike basic LED display drivers, NED200 combines LED display control, Ethernet communication, serial communication, Wiegand input, digital I/O, relay control, and voice broadcasting on a single controller board.

Supports TCP, RS485, and MQTT protocol integration, enabling parking system integrators and software developers to connect the controller to their PMS, parking guidance, access control, or cloud software platforms.

NED200 provides dedicated interfaces for LED display applications:

• 1 × HUB75 interface
• 1 × HUB08 interface
• External expansion for up to 4 × HUB12 interfaces
• HUB75 supports 32-scan display modules

Ideal for parking entrance LED displays, parking guidance signs, access information screens, and customized LED terminals.

Multiple communication interfaces for comprehensive system integration:

• 1 × 10/100M Ethernet
• 2 × RS232
• 1 × RS485
• 1 × TTL

RS232 and RS485 baud rates adjustable from 4800 to 115200bps.

Supports MQTT, TCP, and RS485 protocol docking. System software can use commands to control:

• LED screen content
• Relay outputs
• I/O functions
• Voice broadcasting
• Other controller outputs

Enables integration into customer's own parking or access control software without requiring fixed proprietary platforms.

Provides 1 × Wiegand interface supporting Wiegand 26/34 adaptive, allowing integration with compatible access control readers and related devices.

Comprehensive control capabilities:

• 2 × I/O inputs
• 2 × OC outputs
• 2 × relay dry-contact outputs
• Independent COM / NO / NC relay contacts
• Relay capacity up to 250VAC 10A / 30VDC 10A

Enables interaction with external parking and access-control equipment.

Supports display of more than 100 languages. Built-in font library includes:

English, Simplified Chinese, Traditional Chinese, Thai, Korean, and Arabic.

Supported integration encodings include GBK, UTF8, or UNICODE depending on configuration.

Built-in voice decoding function allows preloaded voice files to be called by ID:

• Up to 8MB voice storage
• Supports up to 256 voice files
• Voice files can be updated on site

Supports remote IAP upgrades through TCP upgrade tool or browser, allowing functions to be added or optimized after deployment. Cloud-based upgrade functions can also be implemented with customer integration.
