The Moxa CBL‑M44M9 is a high-quality breakout cable that converts a single DB44 male connector into four standard DB9 male connectors. Designed for industrial and embedded applications, this cable allows you to connect multiple RS‑232 devices (such as PLCs, sensors, modems, or serial peripherals) to a single multiport serial interface card or embedded module, simplifying wiring and maintaining reliable signal transmission.

Technical Specification

Moxa CBL‑M44M9 / CBL‑M44M9x4‑50 – 4‑Port DB44 to DB9 Serial Cable
