Adder CAB-9M/9F-2M – 2m RS232 Serial Cable, Straight Through

Product Overview

The Adder CAB-9M/9F-2M is a 2m RS232 serial cable with a 9-pin D-sub male connector at one end and a 9-pin D-sub female connector at the other, wired with all lines straight through. This DB9 male-to-female serial cable is the Adder-specified lead for serial connections to Adder KVM equipment, including firmware upgrade and serial control tasks. For installers who need a known-good RS232 extension cable for KVM switches, it removes any wiring guesswork: every pin is carried straight through.

Product Description

Serial connectivity still does quiet, essential work in KVM installations: flash upgrades, configuration access, and RS232 device control alongside keyboard, video, and mouse signals. The catch with serial cabling is that not all DB9 leads are wired alike — null-modem and partially-wired cables look identical from the outside and fail in non-obvious ways. The CAB-9M/9F-2M settles this by carrying all lines straight through, pin for pin, so the cable behaves as a transparent 2m extension of the serial port.

The male-to-female configuration connects a computer's DB9 serial port directly to Adder hardware or extends an existing serial lead by 2m. In practice, this is the cable technicians reach for when applying firmware updates to Adder switch and extender products from a service laptop, or when routing a serial control line from a rack to a nearby console. Keeping a genuine Adder serial upgrade cable in the spares kit avoids troubleshooting sessions caused by mystery-wired DB9 leads. It belongs in the accessory order alongside the switches and extenders it services — see the full Adder Technology collection at Creation Networks.
