Product Features
Technical Overview
This cable adheres to RS232 serial standards, supporting asynchronous data transmission with 9-pin DB9 connectors that are industry-standard for serial communication. The metal hoods encase the connectors to minimize external interference, which is critical in environments with high electrical noise or adjacent electronic equipment.
The extension cable characteristic allows it to bridge gaps between devices without signal degradation, maintaining data accuracy over its 20-foot span. Each connector is precisely engineered with male and female ends to facilitate direct connections between serial ports, eliminating the need for additional adapters in typical deployment scenarios.
This section brings together practical product details such as Cable Type, Cable Characteristic, Cable Length, Product Color, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment. Buyers often need this context to confirm compatibility with existing devices, expected performance in daily use, and whether installation will be straightforward for IT staff or end users.
Key Product Advantages
The primary advantage of this cable lies in its shielded design with metal hoods, which provides superior protection against EMI and RFI compared to unshielded alternatives. This ensures data integrity in electrically noisy environments, reducing the risk of transmission errors that can disrupt operations in industrial, retail, or laboratory settings.
Reliable Data Transfer
Engineered for accuracy and stability, this cable supports quick and dependable serial communication, essential for legacy systems where modern interfaces are not available.
- Minimizes signal interference
- Maintains connection stability over 20 ft
Durable Build Quality
The metal hoods and robust construction enhance physical durability, resisting wear and tear in frequent plug-and-unplug scenarios common in maintenance or reconfiguration tasks.
Deployment / Use Cases
This RS232 shielded cable is ideal for extending connections between serial devices in scenarios where distance or layout constraints prevent direct linking. Common applications include connecting legacy printers, scanners, or modems to computers in office environments, or interfacing with industrial control systems, CNC machines, and laboratory instruments that rely on serial communication protocols.
In retail and hospitality, it can link point-of-sale terminals to peripheral devices, ensuring reliable transaction processing. The shielding makes it suitable for installations near electrical machinery, networking equipment, or other sources of interference, where maintaining signal clarity is paramount for operational continuity.
Industrial Automation
Use in manufacturing or process control systems to connect PLCs, sensors, or HMIs where EMI from motors or power supplies is prevalent.
Legacy IT Support
Extend the life of older computing hardware by providing reliable serial connections for data transfer or device management in environments upgrading gradually.
Physical Profile
The cable features a beige exterior that offers a neutral, professional appearance suitable for both office and industrial settings. With an approximate weight of 481.7 grams, it is lightweight enough for easy handling and installation, yet sturdy due to its shielded construction. The 20-foot length provides flexibility in routing around obstacles or across workstations without taut stretching that could strain connectors.

FAQ
What is the purpose of the metal hoods on this RS232 cable?
The metal hoods provide electromagnetic interference (EMI) and radio frequency interference (RFI) shielding, protecting the serial signal from external noise that can cause data errors. This is essential in environments with electrical equipment or high interference levels.
What devices can I connect with this DB9 male to female cable?
This cable connects devices with DB9 serial ports, such as legacy computers, industrial machinery, point-of-sale systems, printers, and modems. The male end plugs into a female port, and the female end accepts a male connector, making it ideal for extending existing connections.
How long is the cable, and is it suitable for long-distance setups?
The cable is 20 feet (6.10 meters) long, providing ample reach for most office or industrial applications. As an extension cable, it maintains signal integrity over this distance, but for longer runs, consider signal boosters or repeaters to prevent degradation.
Does this cable support fast data transfer speeds?
As an RS232 serial cable, it supports standard serial communication speeds, which are sufficient for legacy devices but slower than modern interfaces like USB or Ethernet. It ensures accurate and stable data transfer, not high-speed throughput.
What warranty comes with the Black Box EDN12H-0020-MF cable?
This cable includes a lifetime limited warranty from Black Box, covering defects in materials and workmanship. This warranty reflects the product's durability and reliability for long-term use in professional settings.
Can I use this cable in environments with high electrical interference?
Yes, the shielded design with metal hoods makes it suitable for high-interference environments like factories, labs, or server rooms. The shielding minimizes signal disruption, ensuring reliable communication even near motors, power supplies, or networking gear.
What refresh rate or brightness details are available?
Display-oriented products are best judged through screen, connectivity, and installation specifications. Those facts help buyers confirm visual fit, mounting flexibility, and deployment suitability more clearly than generic summary text.
What input or connectivity options are listed?
Connectivity options include DB-9 RS-232 Serial - Male, helping the product integrate into common office or home setups.
