2 in 1 Controller Compatible TCP/IP and RS485 Communication Access Control Board
Product Overview
System integrators, security contractors, and facility managers require access control hardware that supports both local and network-based deployment without forcing a choice between communication protocols. The DO-WEG02 2 in 1 controller addresses this need by integrating TCP/IP and RS485 communication on a single access control board, enabling flexible system architecture for small to mid-sized door installations. This controller manages up to two doors with bidirectional card control—entry and exit via card swipe or entry via card and exit via button—making it suitable for office buildings, warehouse zones, laboratory areas, and multi-tenant facilities that require segmented access management.
Purchased by security system distributors, access control installers, and OEM equipment manufacturers, this board solves the common deployment problem of legacy RS485-only panels that cannot scale efficiently over IP networks. By supporting both protocols in one unit, buyers reduce inventory complexity and simplify field configuration. The DO RFID Reader factory builds these boards for high-volume batch consistency, ensuring that long-term supply contracts and multi-site rollouts receive identical hardware revision levels.
Product Advantages
- Dual-protocol onboard – TCP/IP and RS485 coexist on the same PCB, eliminating the need for separate communication modules or protocol converters at each door location.
- Two-door bidirectional control – Each door supports both entry and exit reading, or entry reading with exit button, covering common commercial security patterns without extra controllers.
- 20,000 user capacity – Sufficient for medium-sized organizations where employee turnover and visitor access require stable credential storage without frequent database purges.
- 100,000 event buffer offline – Transactions store locally during network interruption, ensuring audit trail completeness for compliance-driven industries.
- Wide operating temperature range – -40°C to 70°C allows deployment in unconditioned spaces such as parking garages, loading docks, and exterior booths.
- High-speed memory with power protection – Records remain intact after power loss, eliminating manual data recovery procedures on site.
- Remote door control and alarm linkage – Software interface supports forced open/close, interlock, anti-passback, multi-card open, and timed unlock without additional hardware for basic functions.

Industrial Applications
The DO-WEG02 access control board is specified by security system integrators for commercial and industrial environments where dual-protocol flexibility reduces installation labor and future network migration costs. Typical deployment scenarios include:
- Office and corporate buildings – Manage employee access to floors, server rooms, and common areas with per-door control and event logging for internal audit requirements.
- Warehouse and logistics facilities – Restrict entry to inventory zones, loading docks, and maintenance areas where temperature extremes require hardware rated for -40°C to 70°C operation.
- Research and laboratory environments – Enforce multi-card authentication and anti-passback in clean rooms or restricted chemical storage zones where access must be strictly recorded.
- Manufacturing plants – Separate production floor access from administrative areas using interlock and timed unlock schedules aligned with shift patterns.
- Multi-tenant commercial centers – Deploy one controller per tenant space with remote lock/unlock capability managed from a central security office.
