FAQ
What devices is this RS-232 extension cable compatible with?
This cable is specifically designed for desktop computers with DB-25 serial ports. It extends connections to compatible peripherals including serial printers, scientific instruments, industrial control devices, point-of-sale systems, and other equipment utilizing standard RS-232 DB-25 interfaces.
How does the shielding benefit data transfer?
The cable's shielding protects against electromagnetic interference (EMI) and radio frequency interference (RFI) that can disrupt serial data signals. This ensures reliable data transmission over the 20-foot length, particularly important in electrically noisy environments like industrial floors, labs, or offices with multiple electronic devices.
What is the significance of the 28 AWG wire gauge?
The 28 American Wire Gauge (AWG) specification indicates the thickness of the copper conductors inside the cable. This gauge provides an optimal balance between flexibility for routing and sufficient conductivity to maintain signal integrity over the 20-foot extension distance without significant signal degradation.
Can this cable be used with devices other than desktop computers?
While specifically noted as compatible with desktop computers, this RS-232 extension cable works with any equipment featuring standard DB-25 RS-232 serial ports. This includes some industrial controllers, legacy servers, scientific instruments, and specialized peripherals that utilize DB-25 serial interfaces for data transfer.
What does 'extension cable' mean in this context?
As an extension cable, this product adds 20 feet of length to an existing RS-232 connection. It features a male DB-25 connector on one end that plugs into a computer's serial port, and a female DB-25 connector on the other end that accepts the plug from a peripheral device, effectively extending the reach between them.
What warranty coverage does this cable include?
This Black Box cable comes with a lifetime limited warranty, providing long-term assurance of quality and reliability. The warranty covers defects in materials and workmanship for the product's usable life, supporting its deployment in professional environments where continuous operation is essential.
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-25 RS-232 Serial - Male, helping the product integrate into common office or home setups.
