Product Description P/N: 1769-ASCII
Description
The Allen-Bradley 1769-ASCII is a CompactLogix/MicroLogix specialty communication module designed to interface ASCII-compatible devices—such as barcode readers, scales, printers, and sensors—directly into a Logix-based control system. Featuring two fully independent and isolated serial channels, each configurable for RS-232, RS-422, or RS-485, this module offers flexible communication options for industrial environments requiring reliable ASCII data exchange.

Information About 1769-ASCII
The Allen-Bradley 1769-ASCII module enables CompactLogix and MicroLogix 1500 controllers to communicate with devices that use the ASCII protocol. The module includes two isolated DB-9 serial ports, each functioning independently and supporting a variety of serial standards: RS-232/RS-422 (Port 1) and RS-485 (Port 2). Each channel can be configured with unique baud rates, parity settings, and communication modes, allowing simultaneous communication with different ASCII devices. Ideal for barcode systems, data entry terminals, weigh scales, printers, and serial sensors, the 1769-ASCII supports both full-duplex and half-duplex modes. It offers hardware RTS/CTS handshaking and robust diagnostics—such as FIFO overflow indication, parity error detection, handshake errors, and data-ready indicators—making troubleshooting simple and efficient.
Key Features:
- Two independent and isolated serial channels
- Supports RS-232, RS-422, and RS-485 interfaces
- Alternating mode or dual simultaneous channel operation
- Full-duplex and half-duplex communication
- Hardware handshaking (RTS/CTS)
- Extensive diagnostics: FIFO overflow, parity errors, handshake errors
- Backplane-powered—no external supply required
- CompactLogix and MicroLogix 1500 compatible
- Supports ASCII devices such as barcode readers, printers, and scales
- Wide operating temperature and industrial-grade durability
The 1769-ASCII expands a CompactLogix or MicroLogix 1500 system with robust ASCII communication capabilities. With two flexible serial ports and comprehensive configuration options, this module connects a wide variety of legacy and specialty devices directly to a Logix controller. Its rugged design, diagnostic features, and ease of integration make it suitable for packaging lines, labeling systems, data acquisition, and industrial automation requiring serial ASCII communication.
