3System Description
3.1 Overview
The Adnacom AUS324 is a USB 3.2 Gen 2 extender that supports USB 3.2 Gen 2 (10 Gb/s) and Gen
1 (5 Gb/s), 2.0, and 1.1 devices. The system consists of an Adnacom PCIe host adapter and a
USB324 remote unit connected by a fiber optic cable. The system uses a PCIe bus extension over
a fiber-optic cable and standard USB host controllers located in the remote unit. The remote unit
contains 2 AsMedia ASM3142 USB 3.2 Gen 2 host controllers and a PCIe fiber-optic interface. The
system is intended for high-performance USB applications and utilizes the full bandwidth of 2
ASM3142 controllers. The system can operate with QSFP transceivers or active optical cables
(AOCs). The H14 host adapter interfaces one USB324 unit. The H18 host adapter can interface
one or two USB324 units. The system diagrams are shown in Figure 3-1 and Figure 3-2.

Some cables may not work reliably. Other cables must be
tested before using them in the production environment.
3.2.2 Optical Transceivers
The AUS324 can operate with standard multimode and single mode QSFP transceivers. The
transceivers should consume less than 1.5 W to keep their temperature within recommended
operating conditions. If transceivers consume more than 1.5 W, heatsinks should be installed on
the QSFP cages. The transceiver’s power consumption and case temperature can be verified using
the web interface described in section 9.

3.2.3 LC-LC Cables
Multimode and single mode LC-LC duplex cables can be used with single mode QSFP transceivers
with LC connectors. The QSFP transceivers multiplex and demultiplex 4 PCIe Gen 3 lanes into a
single LC-LC duplex cable using Coarse Wavelength Division Multiplexing (CWDM). A single LC-LC
duplex cable supports a 32 Gb/s data rate. The recommended multimode cable types are OM3
and OM4. The recommended maximum cable lengths for different cable types are shown in Table
3-3. System performance depends on the cable length. For further information, visit
https://adnacom.com/aus324/.

4System Operation
4.1 USB Bandwidth Allocation
To achieve the maximum USB data rate, the required device bandwidth must be allocated
between USB ports and host controllers, as described in this section. The USB324 unit contains
two independent ASM3142 USB host controllers, as shown in Figure 3-1. USB ports 1 and 2 are
connected to host controller 1, and USB ports 3 and 4 are connected to host controller 2. Each
controller is connected to the computer over a PCIe Gen 3 x2 link supporting 16 Gb/s bandwidth.
Thus, each host controller operates at full throughput. The 16 Gb/s PCIe link bandwidth is shared
between 2 USB ports of each host controller. Therefore, each USB controller can interface
simultaneously one USB 3.2 Gen 2 device at a full USB 3.2 Gen 2 signaling data rate of 10 Gb/s
and one USB 3.2 Gen 1 device at a full signaling data rate of 5 Gb/s. If two USB 3.2 Gen 2 devices
are connected to the same host controller, the available 16 Gb/s bandwidth is shared between 2
connected devices using standard arbitration rules. The PCIe bandwidth is not shared between 2
host controllers.

5System Installation
5.1 Installation Recommendations
ESD Warning: The electronic parts are sensitive to electrostatic discharges. Please
use an electrostatic wrist strap and/or conductive mat when executing the steps
below.
5.2 Preparing Your Computer
•The H14 and H18 cards do not support overclocking. Please make sure that the PCI Express
clock frequency is set to either the default value or 100 MHz in the BIOS.
•The optical transceivers used in the system do not support PCI Express link power
management. Therefore, disabling all power management features on the computer is
recommended. The step-by-step instructions for Windows 7, 8, and 10 can be found at
https://adnacom.com/aus324. For other OSs, please consult your OS documentation, and if
you need additional assistance, please contact the OS vendor.
5.3 Installing the H14 or H18 Host Adapter Card
•Power off the host computer and unplug its power cord.
•Remove the computer’s cover.
•Identify a PCIe slot on the motherboard that can accommodate x4 or x8 cards.
•Configure the H14 or H18 card using the DIP switch settings described in Table 7-2 or Table
8-2.
•Remove the metal bracket for the slot you have selected.
•Insert the H14 or H18 card into the identified PCIe slot by pushing on it gently. Secure the
card to the computer chassis using a screw.
•There should be sufficient airflow to keep the PCIe card temperature below the maximum
limit.
•Connect the power cord and verify that the red standby LED is ON when the computer is
OFF. If the standby LED is OFF, there is no +3.3Vaux voltage on the PCI slots. Check the BIOS
settings to enable the voltage or reset the BIOS settings to the default values. In Dell
computers, +3.3Vaux is enabled by selecting BIOS Settings->Power Management->Deep
Sleep Control->Disabled.
5.4 Installing the USB324 Unit
•Place the USB324 unit near the USB devices.
•Connect the power supply cable.
•Set the required power control mode described in section 4.2.
5.5 Installing QSFP Transceivers and Connecting Fiber Optic Cables
•Install QSFP transceivers or an AOC.
•If QSFP transceivers are used, connect the host adapter and USB324 with a fiber optic cable.
5.6 Turning on the System for the First Time
•Power on the computer and verify the installation, as indicated in section 6. All drivers are

AUS324 User’s Guide
Rev. 1.0
Adnacom Inc.
10 of 34
https://adnacom.com/
included in the Windows 10 and Linux operating systems. If the drivers are not installed
when the system is powered for the first time, the computer requires one or two restarts.
5.7 Connecting USB Devices
•Install software required to operate the USB devices.
•The USB devices can be connected or disconnected at any time as with any USB port.
•Check that the device is detected and installed correctly in the operating system.

To see if your installation is successful, click on the arrow to the left of the ACPI to open it, then
within PCI Bus, check the lines containing the words “PCI Express Root” or “PCI standard PCI-to-
PCI bridge.” Under one of the lines, you should see three PCI-to-PCI bridges and two AsMedia USB
3.1 Host Controllers, as shown in Figure 6-2.
