KVM for Omega/Ultra Series

Dec 17, 2025

Overview

Just Add Power Omega and Ultra Series systems support KVM (Keyboard, Video, Mouse) over USB, allowing USB peripherals connected at a Decoder to control a source connected to an Encoder.

For a broader explanation of KVM use cases and examples, see: KVM Support Overview

Supported Firmware

USB-based KVM functionality is supported on all Omega / Ultra Series firmware version:

B1.2.1 or greater

KVM Commands

Command: Connect

The KVM (USB) link between a Decoder and an Encoder does not connect automatically. To establish the KVM connection, send the appropriate command to the Decoder.

Firmware B3.0.0 and later: usb connect
Firmware B2.0.0 through B2.3.9: usb start
Note: This may briefly disconnect and reconnect other active KVM sessions.
Firmware B1.0.0 through B1.2.1: video start
Note: This command will cause a brief video interruption.

Command: Disconnect

To break an active KVM link, send the following command to the Decoder:

Firmware B3.0.0 and later: usb stop

Omega and Ultra Series systems support up to five (5) USB devices simultaneously controlling a single Encoder. If five USB devices are already connected and a sixth device attempts to connect, the system will block the new device from connecting (the existing five devices remain connected).

USB Bandwidth and Priority: Omega and Ultra Series devices support a maximum aggregate USB bandwidth of 75.7 Mbps. Audio and video services always take the highest priority and will consume bandwidth as needed. Due to the variable nature of audio and video bandwidth usage, the remaining (surplus) bandwidth available for other USB services—including KVM—is limited and may fluctuate depending on system activity.

Supported USB device types include USB 2.0 Bulk devices, such as:

Keyboard
Mouse
Touchscreen
Gaming controller or joystick
USB flash drive
PTZ camera control devices
