Adaptive Micro Systems Alpha 220C LED Message Display Sign

The Adaptive Micro Systems Alpha 220C LED Message Display Sign is an indoor, single‑line tri‑color (red, green, amber) LED display built for bold, programmable announcements across a long horizontal strip. It measures about 38 inches long by 4 inches high and uses 2.1‑inch tall characters, typically showing up to 20 characters per line (24 in condensed rotate mode). Each pixel is 0.2 inches in diameter with 0.3 inches center‑to‑center spacing, delivering clear text from a distance. Memory holds up to 28,000 bytes, supporting as many as 96 distinct messages and up to 128 message files with scheduling. The sign offers 26 display modes and 9 built‑in animations, plus a real‑time clock and counters to timestamp events. For control and integration, it supports RS232, RS485, and Ethernet (optional), and can be programmed via a remote control keyboard with about a 30‑foot range. The Alpha 220C also provides multi‑language messaging with International Character Set support and retains messages during power outages for up to a month with battery backup. Networking across multiple displays is feasible through RS‑485 wiring and optional Ethernet, making it suitable for call centers, movie theatres, schools, and other environments where safety alerts, promotions, or real‑time updates must be visible in large spaces. Its slim, open‑back/flush‑mount design facilitates wall installation while maintaining legibility at distance.
