Product Overview
The Adder VSC40 upgrade cable connects the serial port of a computer to the Options port of an Adder AV4PRO family KVM switch or CCS4-USB command and control switch for firmware upgrades and serial control. This Adder flash upgrade cable combines a 9-way D-type female adapter with an RJ45 (8P8C) patch lead, giving administrators a 3-meter reach between the service laptop and the rack. For AV teams maintaining AdderView PRO switches, keeping a VSC40 serial upgrade cable on hand is the simplest way to apply firmware updates and configure units in the field.
Product Description
Firmware maintenance is part of the lifecycle of every professional KVM deployment, and Adder designs its AV4PRO and CCS4-USB switches to be upgraded through a dedicated Options port rather than requiring the unit to be pulled from the rack. The VSC40 is the manufacturer-specified cable for that task: a flash upgrade adapter with a 9-way D female connector for the computer's serial port, paired with a standard 3-meter RJ45 patch lead that plugs into the switch's Options port.

Beyond firmware flashing, the same connection is used for serial configuration tasks on supported Adder switches, such as programming options on CCS4-USB installations per the Adder user guides. The 3-meter length provides comfortable working distance in equipment rooms where the service laptop sits on a cart or bench away from the rack. Integrators who deploy AdderView PRO multi-port KVM switches typically order one VSC40 per site so upgrades never wait on a missing cable. It is a low-cost insurance item that belongs in every Adder maintenance kit. Browse the full range of Adder accessories in our Adder Technology collection.
