Mercury MRDT Reader

MRDT

The MRDT display terminal provides an interactive link to an access system. In addition to improving the system’s general usability, it can bring display and control functions historically limited to the system console to anywhere in the facility. The MRDT displays text as sent by the controller, providing access and alarm status feedback or other freeform messaging or instructions that the system generates.

The MRDT combines a 32-character LCD display, a multiposition keypad and a reader port, all in a single package. Even in challenging settings, the back-lit LCD yields clear information displays. The keypad features standard numerics and 4 function keys to select display options. Deployed with the Mercury family of access platforms, the MRDT is capable of creating custom tasks with any of the functions keys, which mimic system command console functionality at the doorway. The reader port supports Wiegand, magnetic stripe and proximity devices. The unit connects to the system via either a 2-wire RS-485 link or a TTL connection. Menu-driven configuration is easily conducted at the keypad.

Application Notes

The MRDT display terminal is a core component that provides robust communications functionality within Mercury’s building block approach to system design. When combined with Mercury’s EP or AP series of intelligent access platforms, the unit brings an interactive link and truly integrated functionality to the terminal, a major plus for end-user convenience and satisfaction. The MRDT’s flexible messaging also allows for easy expansion of system benefits functionality beyond access control.
