RS485 Double Door Access Control Panel
Product Overview
The DO-WEG02 RS485 Double Door Access Control Panel is a TCP/IP networkable controller designed for commercial and industrial access management applications. This panel supports Wiegand 26 and Wiegand 34 protocols, enabling integration with a wide range of RFID card readers, biometric readers, and keypad entry devices. System integrators, security contractors, and facility managers select this panel when they need reliable two-door control with offline event buffering, remote unlocking capability, and flexible door scheduling. The controller accepts up to 20,000 users and stores 100,000 transaction records, making it suitable for office buildings, factory floors, warehouse zones, gated communities, and multi-tenant facilities where uninterrupted access logging is required even when network connectivity is temporarily lost.
As a do rfid reader manufacturer, we produce this control panel for distributors, wholesale buyers, and project deployment teams who require consistent hardware behavior across large-scale installations. The RS485 and TCP/IP dual communication channels allow existing sites to migrate from legacy serial wiring to modern IP infrastructure without replacing the entire access control infrastructure. Bulk procurement is supported with stable production capacity, ensuring that multi-site rollouts receive identical hardware revisions and firmware behavior.
Key Features
- Dual Door Control — Manages two independent doors with entry and exit read capability or entry card swipe with exit button configuration for each door.
- Wiegand 26 & 34 Compatibility — Works with HID, EM, Mifare, and Motorola protocol readers, giving integrators flexibility when sourcing reader hardware for specific client budgets or security levels.
- TCP/IP and RS485 Communication — Supports both local serial control and remote IP-based management. System administrators can configure, monitor, and unlock doors from a central workstation or mobile management interface.
- 20,000 User Capacity — Suitable for facilities with rotating staff, multiple work shifts, or seasonal workforce changes without requiring frequent database uploads.
- 100,000 Event Buffer — Offline transaction storage ensures that door events, alarm triggers, and card swipes are recorded even when the network is down. Data is automatically uploaded once connectivity is restored.
- Alarm Functions — Supports door forced open alarm, door open too long alarm, and tamper alert. When connected to the DO-EA05 expansion board, hardware alarm outputs can drive sirens, strobes, or notification panels.
- Interlock and Anti-Passback — Prevents tailgating by enforcing entry and exit card rules. Interlock logic ensures that one door must close before the other can open, which is required for high-security zones, vault rooms, and cleanroom airlocks.
- Multi-Card Open and First Card Unlock — Supports multi-person authentication for sensitive areas. First card unlock feature allows the first valid credential to disarm the alarm and activate normal operation mode at the start of a work shift.
- Remote Door Control — Authorized personnel can force unlock, force lock, or momentary unlock doors from the management software. This reduces the need for physical key access during emergencies or maintenance events.
- Door Open Time Adjustment — Configurable from 1 to 600 seconds per door, accommodating magnetic locks, electric strikes, and automatic sliding doors with different release durations.

Industrial Applications
The DO-WEG02 access control panel is deployed in commercial office buildings, manufacturing plants, warehouse logistics centers, data centers, research laboratories, educational campuses, and gated residential communities. System integrators choose this panel when project requirements demand two-door control with the ability to expand to multi-door configurations using the same software platform. Distributors and wholesalers stock this model because it supports both standalone and networked deployment, reducing inventory complexity.
For industrial environments, the wide operating temperature range (−40 °C to 70 °C) allows installation in unheated storage facilities, cold chain warehouses, and outdoor security kiosks. The anti-passback and interlock features are critical for cleanrooms, pharmaceutical production zones, and high-security government facilities where personnel movement must be strictly tracked and controlled.
OEM / ODM Manufacturing Support
As a do rfid reader manufacturer with over 20 years of production experience, we offer OEM and ODM customization for the DO-WEG02 control panel. Customization options include:
- PCB layout modification for integration into existing enclosure designs or custom housing requirements.
- Firmware customization for proprietary communication protocols, specific Wiegand formats, or custom alarm logic sequences.
- Brand labeling and packaging for distributor partners who require private labeling on both the PCB board and the packaging materials.
- Interface adjustments to support alternative reader voltage levels, dry contact inputs, or specialized lock types used in regional markets.
OEM buyers benefit from batch consistency across production runs, with each panel undergoing functional testing before packing. This ensures that large-scale deployments receive identical hardware behavior, reducing on-site configuration time and technical support overhead.
