Product Features
Technical Overview
This serial cable features 28 AWG wiring with full shielding to prevent electromagnetic interference (EMI), ensuring data integrity in electrically noisy environments. The connectors are molded with strain relief to protect against physical stress and cable pull-out, extending the cable's lifespan in frequent-use scenarios. The nickel plating on the DB9 connectors resists corrosion and maintains reliable electrical contact over time.
The cable supports RS-232 signaling standards, compatible with devices requiring serial communication at typical baud rates. Its 1-meter length provides flexibility for close-proximity connections, while the black color blends discreetly into office or rack setups. The construction meets environmental standards, including RoHS 2, REACH, and WEEE, reflecting a commitment to reduced hazardous substances.
This section brings together practical product details such as Cable Type, Cable Length, Connector Type on First End, Color Family, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.

User Manual
FAQ
What is a null modem cable, and when should I use it?
A null modem cable crosses the transmit and receive lines, allowing two DTE devices (like computers) to communicate directly without a modem. Use it for tasks such as file transfers between PCs, configuring network equipment via serial console, or connecting legacy devices that require direct serial links.
What devices are compatible with this DB9 RS232 cable?
This cable is compatible with any device featuring a female DB9 RS-232 serial port, including older computers, routers, switches, modems, industrial controllers, and point-of-sale systems. It supports standard RS-232 signaling for data communication.
How does the shielding protect against interference?
The cable includes full shielding that blocks electromagnetic interference (EMI) from nearby power cables, motors, or other electronic devices. This prevents signal degradation and data errors, ensuring reliable transmission in environments with electrical noise.
What are the benefits of molded connectors and strain relief?
Molded connectors and strain relief reinforce the cable ends, preventing wire breakage from bending or pulling. This durability extends the cable's lifespan, especially in frequent-use or industrial settings where physical stress is common.
What environmental standards does this cable meet?
This cable complies with EU RoHS 2, REACH, and WEEE standards, meaning it restricts hazardous substances like lead and mercury. This makes it suitable for environmentally conscious deployments and aligns with global regulatory requirements.
