The Allen-Bradley 1769-ASCII is a specialized ASCII interface module designed for the CompactLogix and MicroLogix 1500 controller platforms. This module acts as a powerful bridge, enabling seamless communication between the controller and various serial devices that use ASCII protocol, such as barcode scanners, printers, weigh scales, and operator terminals. It features two configurable serial ports that support RS-232, RS-422, and RS-485 communication standards, offering exceptional flexibility for integrating diverse equipment into your automation system. By offloading the task of ASCII string processing from the main CPU, the 1769-ASCII module enhances overall system performance and simplifies application programming.
