Software House GSTAR-ACM-4U iSTAR Ultra G2 ACM in 4U Rack Enclosure

The Software House GSTAR-ACM-4U is an Access Control Module (ACM) for the iSTAR Ultra G2 platform, housed in a 4U rack-mount enclosure for enterprise access control installations. Designed to expand system capacity, the module supports up to eight card readers, making it an ideal solution for organizations requiring scalable, centralized door management.

The GSTAR-ACM-4U integrates seamlessly with the iSTAR Ultra G2 General Controller Module (GCM), providing advanced reader management, supervised inputs, programmable outputs, and secure communications. Built on the cyber-hardened iSTAR Ultra G2 architecture, it supports modern access control technologies, including Wiegand, OSDP Secure Channel, and wireless lock integrations, while delivering enterprise-grade security and reliability.

Features:

• A powerful cyber-hardened network door controller for up to 32 readers
• A hardened Linux embedded OS for improved security and scalability, with up to one million cardholders in local memory
• Advanced controller-to-controller communications for cluster-based anti-passback and I/O logic
• Trusted Execution Environment for advanced hardware-based cybersecurity protection
• Dual GigE network ports with IPv6, DHCP and 802.1X support, and a Power over Ethernet (PoE) module featuring PoE+ to power the GCM
• Supports OSDP Secure Channel for encrypted reader communications, as well as embedded High Assurance FICAM operation without third-party hardware
