Black Box EGM12D-0005-FF Extended-Distance/Quiet Cable with Nonremovable EMI/RFI Hood - Stranded, DB9, Straight-Wired, 9 (4 1/2 Pairs)—All Pins, 5-ft. (1.5-m), FF. New in wrap.
Made for short runs in extra-noisy environments.
100% foil shield plus a tinned copper-braid.
24 AWG stranded copper conductors.
Guaranteed for life!
Protect your data from end to end with a 100% foil shield plus an 85% tinned copper-braided shield.
Ideal for industrial environments. EMI/RFI-resistant hoods stop damaging noise where cables are most vulnerable—at the connection.
In extra-quiet environments, use these cables for long runs—up to 500 feet (152.4 m) at 9600 bps.
In extra-quiet environments, use it for long runs up to 500 feet (152.4 m) at 9600 bps.
Also available with removable hoods.
Noise bursts can come from just about anywhere—fluorescent lighting, radio or cellular transmitters, electrical wiring, and other data cables. Electrical energy from any one of them can scramble your data.
If you have long cable runs or you work in a noisy area, you need the cable that ensures every bit of your document will be accounted for when it arrives at the printer, the modem, or your PC. Convenient thumbscrews ensure tight, solid connections. No more twisting screwdrivers. These cables are built for quick connect/disconnect.

Black Box Explains...RS-232..
RS-232, also known as RS-232C and TIA/EIA-232-E, is a group of electrical, functional, and mechanical specifications for interfaces between computers, terminals, and modems. The RS-232 standard was developed by the Electrical Industries Association (EIA), and it defines requirements for connecting data communications equipment (DCE)—modems, converters, etc.—and data terminal equipment (DTE)—computers, controllers, etc.) devices.
The standard, which is functionally equivalent to ITU V.24/V.28, specifies the workings of the interface, circuitry, and connector pinning. Both sync and async binary data transmission fall under RS-232. Most PCs use the RS-232 interface to transmit data to modems, and some printers even use it.
Although RS-232 is a “standard,” you cannot necessarily expect seamless communication between two RS-232 devices. Why? Because different devices have different circuitry or pinning, and different wires may be designated to perform different functions.
The typical RS-232 connector is DB25, but some PCs and other data communication devices have DB9 connectors. To connect 9-pin PC ports to devices with 25-pin connectors, you need a simple adapter cable. The most commonly used interface, RS-232 is ideal for transmitting data at speeds up to 20 kbps and over distances up to 50 feet (15.2 m).
