Software House USTAR-GCM iSTAR Ultra Access Control Board

The Software House USTAR-GCM iSTAR Ultra Access Control Board is a network-ready general controller module designed for enterprise access control installations. It serves as the central processing unit of a compatible iSTAR Ultra system, coordinating access control modules, reader communications, door security functions, and system events. The board supports up to four Access Control Modules (ACMs) and manages up to 500,000 cardholders in local memory. Security features include a hardened embedded Linux operating system, 256-bit AES network encryption, and support for OSDP Secure Channel for encrypted reader communications. Additional capabilities include global anti-passback, peer-to-peer clustering, native intrusion zone functionality, and a dedicated fire alarm input for door-lock override integration. An onboard LCD provides controller status and diagnostic information. The board measures approximately 6.5 x 10.5 x 1.02 inches and requires a 12 VDC power input. It is designed for integration with compatible Software House iSTAR Ultra access control systems.
