AXU-SPL4 Mini-LCD Panel
Introduction
The AXU-SPL4 Mini-LCD Panel is a versatile product primarily designed for civic and
commercial voting systems. However, the it can also accommodate a broad range of other
commercial applications. The backlit LCD has a two line by 16-character menu that provides time,
date, user name, menu titles, and control function information. Menus are modified using Axcess
programming software. The bottom menu line can be used to define the functions of the four LED
pushbuttons. For example, a voting menu could provide choices for YES, NO, ABSTAIN or
CANCEL. A meeting menu can have a member's name, time, and date on the top line, and REQ,
CANCEL, and MUTE on the bottom line to control the request-to-speak microphone operation.
