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.

4.2 USB324 Power Control Modes

Table 4-1. USB324 Power Control Modes.

Mode

Description

OFF

The USB324 is turned ON and OFF automatically when the computer is

turned ON and OFF

The USB324 is always ON

Note: Disconnection of the fiber optic cable or cycling the USB324 power supply during operation

requires a computer restart.

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.
