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

Hardware Features
1. Net P Status LED
Multicolour LED. Illuminates in Switched mode or Redundant mode:
•Green (Solid) – Primary Link active (DHCP)
•Blue (Solid) – Primary Link active (Static IP)
•O – No network connection
2. Sync P Status LED
Multicolour LED. Illuminates in Switched mode or Redundant mode:
•Blue (Solid) – Confirms card is a Dante PTP leader; the card is set (via Dante Controller) to
generate the Dante clock which will be used by other units
•Green (Solid) – Confirms card is a Dante PTP follower; the card will sync to the clock
embedded in the incoming Dante bitstream
•Red (solid) – No PTP sync
3. Net S Status LED
Multicolour LED:
•Green (Solid) – Secondary Link active (DHCP)
•Blue (Solid) – Secondary Link active (Static IP)
•O – No network connection
•Purple (Solid) – Indicates card is in Switched mode
4. Sync S Status LED
Multicolour LED. Illuminates in Redundant mode only:
•Blue (Solid) – Confirms card is a Dante PTP leader; the card is set (via Dante Controller) to
generate the Dante clock which will be used by other units
•Green (Solid) – Confirms card is a Dante PTP follower; the card will sync to the clock
embedded in the incoming Dante bitstream
•O – No network connection
•Purple (Solid) – Indicates card is in Switched mode
5. Reset Switch
Clears current configuration (Name, IP config, etc.). Press and hold for seven seconds to return the
card to its default state with the DHCP setting.
When pressed, the front panel LEDs will illuminate in sequence at one-second intervals. All LEDs will then
flash for a further three seconds, aer which the card will reset.

6. Primary Network Port
RJ45 connector for the Dante network. Use shielded Cat 5e or better network cables to connect the
card to the Ethernet network switch.
Adjacent to both network sockets are LEDs which illuminate to indicate a valid network connection
and network activity.
7. Secondary Network Port
Secondary Dante network connection where two independent Ethernet links are being used
(Redundant mode), or an additional port on an integral network switch on the primary network
(Switched mode). The operating mode is set via Dante Controller.
The Dante network can be viewed or controlled via either port.

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.
• Do not touch the PCIe edge connector contacts.
• If you don't have an ESD wrist strap, always touch an unpainted surface of your computer's chassis
before handling the card.
• Avoid walking across carpeted areas during installation

Soware Installation
You can download all the soware you need for a RedNet system from the Focusrite website aer you register
your RedNet PCIeNX at: focusrite.com/register.
You can control RedNet functions from RedNet Control, and define routing in Dante Controller.
Audinate Dante Controller
To download Dante Controller go to: audinate.com. Aer registering, you can download and install the
application.
RedNet Control 2
The Product Registration Card provided with your RedNet device contains a validation code, which you need to
enter in the Registration area.
Follow the instructions on the card to register your product and download RedNet Control 2 and associated
soware.
Aer it's downloaded, you can install the RedNet Control 2 application. Follow all on-screen instructions from
this point.
RedNet Control is always available for anyone to download from downloads.focusrite.com/focusrite-pro
System Power Up
We recommend you power on the components in a RedNet system as follows:
1. Power up the Gigabit switch(es)
2. Power up all RedNet units on the network
3. Boot the host computer
Once your computer has finished booting, open RedNet Control 2.
RedNet PCIeNX User Guide
9
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
