Three controllers are for sale, each was pulled from a different ACS and can be used with a number of ACS systems with a simple firmware flash.  Each controller was logged into via default communication paths to verify functionality.  All sales on electronic devices are final.
The EP1501 is an edge-capable intelligent controller that is
expandable up to 8 downstream SIO controllers and up to
16 MR51e network ready door controllers (for a total of 17
doors/openings).
Built on the Authentic Mercury platform, the feature-rich
EP1501 provides OEMs with a small footprint, cost effective dual card reader panel for controlling a single
opening. Easy installation with Power over Ethernet (PoE)
makes the high performance, Ethernet ready EP1501 a top
choice for a single-door controller.
Once configured, the intelligent controller functions
independently of the host and can control access and
manage sophisticated device processes (such as anti-passback and point linking) both onboard and downstream
of the EP1501 without host intervention.
Offering powerful flexibility, the Mercury EP1501 can
interface with an array of reader technologies for a single
opening. The controller supports separate in/out readers
and technologies: Wiegand, clock and data, RS-485,
OSDP, magnetic stripe, F/2F, Supervised F/2F Readers,
keypads, LCD, and biometrics.
The EP1501 provides the versatility and reliability needed
to deliver powerful innovation for system success and at the
system’s edge when needed.
Application Notes
The EP1501 seamlessly interfaces a single opening to
a larger system (up to 17 openings) for easy expansion.
Providing all of the intelligence and functionality of the
Mercury family of controllers, the EP1501 is PoE capable
and sets the standard for powerful, reliable performance, all
at an economical price point for OEMs.
