Introduction
Thank you for investing in the Focusrite RedNet system.
RedNet is a powerful, low-latency, digital audio networking system designed specifically for music, recording
studio, live, and broadcast applications. RedNet is based on Audinate’s Dante, a well-established audio
networking technology known for its extreme robustness. Dante – and the RedNet system – is capable of
transporting up to 512 channels of bidirectional audio (at 48 kHz sample rate) over a single gigabit Ethernet
link.
The RedNet PCIeNX card provides the hardware interface between the host computer and the Ethernet
network, interconnecting the various I/O units in a RedNet system.
Key Features
• Standard PCI Express installation
• Compatible with standard network switches
• 128 × 128 redundant channels at up to 192KHz
• Seamless operation with other RedNet and Dante devices
• Support for macOS and Windows
• Supports AES67, Dante Domain Manager, and is SMPTE ST 2110 compliant, which makes it perfect for
broadcast deployment
When installed in a 4-lane (minimum) PCIe card slot in either a PC, Mac or Thunderbolt chassis, the RedNet
PCIeNX card allows up to 128 channels to be sent to/from the DAW through its on-board Ethernet ports.
Note
To achieve the best performance, we recommend using a 16-lane PCIe card slot.

System Requirements
OS Version
The easiest way to check if your computer’s operating system (OS) is compatible with the RedNet PCIeNXis to
use our Help Centre’s compatibility articles:
focusritepro.zendesk.com/hc/categories/360000105489-Compatibility
As new OS versions become available over time, you can continue to check for further compatibility
information by searching our Help Centre at:
focusritepro.zendesk.com
PCIe Expansion Slot
A full-height, half-length, 4x to 16x lane PCIe slot, supporting PCIe 2.1.
Network
The Audinate Dante protocol, on which RedNet is based, uses standard Ethernet technology for the network.
Whilst Dante traic can be mixed with other network data, we recommend that for maximum performance, the
RedNet audio network should be self-contained and should not also be used for other IT purposes.
RedNet is compatible with Cat 5e and above cabling; Cat 6 STP is preferred. Standard RJ45 connectors with
metal screens should be used, with the cable screen bonded to the connector screen.
Important
This product Satisfies FCC regulations when high-quality shielded cables are used to connect with
other equipment. Failure to use high-quality shielded cables or to follow the installation instructions
within this manual, may cause magnetic interference with appliances such as radios and televisions
and void your FCC authorisation to use this product in the USA.
Network Switches
• Gigabit (1000 Mbps) capable – switches below this rating are not supported
• Quality of Service (QoS) with 4 queues
•Diserv (DSCP) QoS, with strict priority
• Should be of the ‘managed’ type to provide detailed information about the operation of each network
link: port speed, error counters, bandwidth used, etc.
• ‘Non-blocking’ to allow full bandwidth of all ports simultaneously
• An internal mains power supply is recommended – the external “plug-top” PSUs supplied with some
units can be prone to interference which could generate audible artefacts

RedNet PCIeNX Installation
Hardware Installation
You must switch o and disconnect the mains supply for your computer before beginning the installation of
the RedNet PCIeNX card. Hot-plugging is NOT supported.
Allow the computer to cool down before you begin installing.
Refer to your computer’s technical manual for instructions on how to install the PCIe card.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can irreversibly damage the product. You must observe the following ESD
precautions when installing the card:
• Wear an ESD wrist strap connected to an unpainted surface of the computer’s chassis. The strap should
fit snugly against the skin to ensure a reliable connection.
• Keep the PCIeNX card in its ESD bag until you need it.
• Only grip the card by its edges or front panel; avoid touching any of the component parts.

Connecting your RedNet Audio Network
We recommend all Ethernet connections in your Dante system are made using CAT 6 STP cables.
Note
The RedNet PCIeNX includes a ‘virtual’ Ethernet port to enable control data to be passed through to
remote RedNet I/O devices. There is therefore no need to connect any other network ports on your
computer to your Dante network.
Standard Network
This setup requires only one gigabit network switch:
• Connect the Primary RedNet PCIeNX card port to the gigabit switch
• Connect the Ethernet ports on each RedNet I/O interface in your system to ports on the gigabit switch.
Daisy-chain to additional RedNet device. ‘Switched’ mode

Redundant Network
You can use a redundant network for RedNet devices with both Primary and Secondary network ports. If the
primary network fails, audio transmission seamlessly switches to use the secondary network. This redundant
setup is oen found in Live and Broadcast applications.
A redundant network requires a minimum of two network switches:
• Connect the Primary port of the RedNet PCIeNX card to the primary network switch
• Connect the Secondary port of the RedNet PCIeNX card to the secondary network switch
• Connect your other Dante device(s) Primary and Secondary ports to the primary and secondary
network switches respectively for each device
Note
Do not make any connections between the primary and secondary network switches.

Operation
Audio Routing in your DAW with RedNet Control 2
Your DAW allows you to select which RedNet audio channel feeds each track. Please refer to your DAW’s
documentation or Help files if you are unsure about this.
The RedNet PCIeNX card will be detected by your DAW and added to the list of available audio sources. Select
PCIeNX (macOS) or Focusrite Thunderbolt ASIO (Windows).
RedNet PCIeNX User Guide

Using Dante Controller
Audinate Dante Controller is installed on your computer as part of the RedNet Control 2 installation. You can
open Dante Controller either by going to its shortcut (in Applications on Macs or in All Programs in Windows),
or by selecting ‘Launch Dante Controller...’ from the right-click Utility menu in RedNet Control 2.
The Routing tab is arranged as a cross-point matrix. Audio inputs are listed horizontally (called Dante
Transmitters) and audio outputs are listed vertically (called Dante Receivers).
You can expand the I/O matrix for each RedNet and Dante device – to reveal its full set of inputs or outputs – or
collapse by clicking the appropriate ‘+’ or ‘-’ symbol against each device’s name. Some devices may have only
inputs or outputs.
The RedNet PCIeNX card appears as a device with Dante Transmitters and Dante Receivers, as it has both
inputs and outputs.
• To create an audio connection (called a subscription), click on the appropriate crosspoint between
the RedNet PCIeNX card and your other Dante I/O device. When the connection is made (a successful
subscription), a green tick icon will appear.
• For incremental 1:1 routing within a single RedNet device, Ctrl-click on the first subscription cross-point
Note

Appendix B. A note about Latency
No digital audio system is “instantaneous”; the term “latency” is used to express the time by which the
audio is delayed in travelling through the system. In practice, latency only becomes a problem when mixing
signals from systems having significantly dierent delays. The Dante protocol used by RedNet exhibits very
low latency, and you should not experience any problems in normal recording practice when using it for
multichannel audio transport between a DAW and sources or monitoring.
The precise latency of any given system will be determined by multiple factors, including the processing speed
of the computer, the number of switches in the network, or make/model of switch used and the network
topology.
If you are using Dante Virtual Soundcard instead of the RedNet PCIeNX card, the computer requires additional
processing time.
