Mdi acu-6
ACU-6 can be configured to control one account or multiple accounts via firmware. Up to eight (8) ACU-6 units can be interfaced to a single RTU. Each ACU-6 communicates with the RTU via a FIM22 using 2-wire twisted pair cable using standard 2-wire RS-485 communications.
The ACU-6 uses an unmarked keypad in combination with a four-line, 80-character Liquid Crystal Display (LCD) for security code entry and data selection. Six unlabeled “soft†keys are located above and six below the LCD. In some modes of operation five of the keys above and below represent the numeric keys (0 – 9). These keys may be labeled in four different methods; horizontal (1,2,3,4,5 on top, and 6,7,8,9,0 on bottom), vertical (1,3,5,7,9 on top and 2,4,6,8,0 on bottom) or, for higher security, Rotational and Rotational-PLUS.
The Rotational method presents a new arrangement of number assignments to the keys for each use. The Rotation-Plus presents a new arrangement of number assignments to the keys after each keystroke. In either Rotational modes the keys are always shown in numerical order, similar to the horizontal method, however the starting point is always different and randomly determined.
This dynamic keypad labeling makes available the following ACU-6 functions:
