Adder VSC27 – RS232 Video Cascade Cable, 200mm

Product Overview

The Adder VSC27 is a 200mm RS232 video cascade cable used to synchronize multiple AdderView KVM switches in dual-head and multi-display KVM switching configurations. With a 9-pin D-type male connector on each end, this short Adder KVM cascade cable links the RS232 ports of adjacent switch units so channel changes occur in unison across every connected display. It is a purpose-built interconnect for rack-mounted Adder multi-monitor KVM deployments where a standard serial cable would add unnecessary slack.

Product Description

When a single operator needs to control multiple computers across two or more monitors, integrators typically pair AdderView KVM switches together — one switch per video head. The VSC27 RS232 synchronization cable is the link that keeps those paired switches in step: select a channel on the primary unit and the cascaded unit follows automatically, so keyboard, mouse, and every video head switch together.

At just 200mm, the cable is sized for switches mounted directly above or beside one another in a rack or on a desk, keeping serial interconnects tidy and strain-free. The 9-pin D-type male-to-male format mates directly with the options/serial ports on compatible AdderView units without adapters. For installers standardizing on Adder hardware, the VSC27 is the factory-specified part for multi-display switch synchronization, which removes the guesswork of pinning out a custom DB9 cable.
