Allen-Bradley 1788-MCHKR Handheld Network MediaChecker for Industrial Cables

Product Overview

The AB 1788-MCHKR is a portable handheld Network MediaChecker designed for diagnosing wiring faults, verifying cable integrity, and measuring lengths across industrial communication media. It provides accurate and reliable diagnostics for Ethernet, ControlNet, DeviceNet, and DH+/RIO systems.

This device identifies shorts, opens, miswires, and split pairs while generating detailed wire maps for twisted-pair cables. Its high-resolution length measurements allow precise cable verification from 1 m up to 650 m depending on the protocol. Equipped with a rotary switch, the 1788-MCHKR enables intuitive mode selection for quick testing in various environments.

The MediaChecker includes a built-in cable library and supports cable-specific calibration to maintain measurement accuracy. Audible alerts indicate pass/fail results and active cable detection, improving efficiency during on-site diagnostics. Compact dimensions (18.4 × 9.8 × 4.6 cm) and lightweight design (354.4 g) ensure portability and easy handling.

Powered by 2 × 1.5 V AA alkaline batteries, it offers up to 50 hours of continuous operation, suitable for extended field use. The LCD displays test results clearly, while input connectors (RJ45, DB9, BNC) support multiple cable types for versatile industrial applications.
