Safety Instructions

Electrostatic Discharges (ESD)
A sudden electrostatic discharge can destroy sensitive components. Proper packaging and earthing rules must therefore be observed. Always take the following precautions.
1. Transport boards and cards in electrostatically secure containers or bags.
2. Keep electrostatically sensitive components in their containers, until they arrive at an electrostatically protected workplace.
3. Only touch electrostatically sensitive components when you are properly earthed.
4. Store electrostatically sensitive components in protective packaging or on anti-static mats.

Grounding Methods

The following measures help to avoid electrostatic damages to the device:

5. Cover workstations with approved antistatic material. Always wear a wrist strap connected to workplace as well as properly grounded tools and equipment.
6. Use antistatic mats, heel straps, or air ionizers for more protection.
7. Always handle electrostatically sensitive components by their edge or by their casing.
8. Avoid contact with pins, leads, or circuitry.
9. Turn off power and input signals before inserting and removing connectors or connecting test equipment.
10. Keep work area free of non-conductive materials such as ordinary plastic assembly aids and Styrofoam.
11. Use field service tools such as cutters, screwdrivers, and vacuum cleaners which are conductive.
12. Always place drives and boards PCB-assembly-side down on the foam.

Introduction

Hardware Description

USB Ports
The HUB7SSBA integrates SeaLATCH USB 3.1 ports, which are fully compatible with standard USB cables. When used with the optional USB cable with a SeaLATCH USB 3.1 type B connector (CA746/CA748), the metal thumbscrew provides a secure metal-to-metal connection to the hub and prevents accidental cable disconnection.

The SeaLATCH USB 3.1 type B locking connector and standard USB 3.1 type B port is shown below:

The HUB7SSBA’s seven SeaLATCH USB 3.1 type A locking connectors can secure USB peripherals to the hub in the same way. Two of the SeaLATCH USB 3.1 type A ports are shown below. Each of the seven downstream type A USB ports provides up to1500mA to USB peripherals with port seven providing up to 2400mA.

Each downstream port of the HUB7SSBA has its own transaction translator to provide the best USB performance no matter what class of USB device is connected it.

1500mA Ports :
Each HUB7SSBA has six CDP ports that can supply up to 1500mA. When there is no upstream host connection, these ports are dedicated charging ports, supporting vendor specific charging (RapidCharge; Apple® 2.0A).

2400mA Port:
Each HUB7SSBA has a single, high-power port that can supply up to 2400mA. When there is no upstream host connection, the high-power port is a dedicated charging port, supporting vendor specific charging (RapidCharge; Apple® 2.4A).

Status LEDs
Each downstream port has a status LED that is visible from the front of the HUB7SSBA module to indicate the following information:

• USB 2.0/1.1/1.0 Connection with Host (Yellow) – Lights when a USB 2.0, 1.1, or 1.0 connection is established with the upstream host.
• USB 3.1 Connection with Host (Green) – Lights when a USB 3.1 connection is established with the upstream host.

External Power

The HUB7SSBA can be ordered with an optional industrial grade desktop power supply (Item# TR152) that outputs 24VDC @ 2.71A. Power is input via a 5mm 2-position removable screw terminal block (shown below). To prevent accidental disruption of power, the terminal block includes captive mounting screws for securing to the hub. The HUB7SSBA accepts a wide input voltage range from 9VDC to 30VDC for use with alternative power supplies.

The HUB7SSBA is powered via 2-pin terminal-block and is configured as a self- powered device that consumes less than 1 mA of upstream VBUS current. Each downstream port is configured as a Charging Downstream Port (CDP) capable of delivering up to 1500mA with port 7 capable of delivering up to 2400mA.

SeaLATCH® USB 3.1

The HUB7SSBA integrates SeaLATCH USB 3.1 ports, which are fully compatible with standard USB cables. When used with the optional USB cable (Item# CA748) with a SeaLATCH USB type B connector, the metal thumbscrew provides a secure metal-to-metal connection to the hub and prevents accidental cable disconnection.
The hub’s seven SeaLATCH type A USB 3.1 connectors can secure USB peripherals to the hub in the same way. Sealevel incorporates SeaLATCH locking USB ports on many USB I/O devices. Accidental cable disconnection is the most common point of failure with USB industrial I/O devices and SeaLATCH cables and connectors prevents that while being fully compatible with standard USB cables.

Examples of the HUB7SSBA with SeaLATCH equipped Sealevel I/O devices are shown below:

SeaLATCH Locking USB 3.1 Cables

SeaLATCH locking USB 3.1 cables integrate a small thumbscrew into each USB connector. SeaLATCH USB 3.1 cables are fully interchangeable with standard USB cables. The thumbscrew provides a secure metal-to-metal connection preventing accidental disconnection. SeaLATCH USB 3.1 cables are available in three configurations.

Mounting Options

DIN Rail Mounting
The HUB7SSBA is available with a factory-installed DIN-rail mounting clip. Alternatively, DIN-rail mounting clips can be ordered as a field upgrade kit (Item# DR106). The bracket with clip is easily attached using two included

4-40 Phillips head machine screws.

Appendix A – Troubleshooting

The HUB7SSBA is a generic SuperSpeed USB hub and should provide years of trouble-free service. Should the device appear to not be functioning correctly, the following tips can eliminate most common problems without the need to call Technical Support.

1. Make sure the power supply is connected to the hub and to a live AC power outlet.

2. Make sure the hub is connected to a USB port using the included USB cable or quality replacement USB cable.

3. The hub is fully supported as a USB 3.1 hub device in any operating system that supports SuperSpeed USB hub devices, including Windows 8 & Windows 10.

4. The hub is supported as a USB 2.0 hub device in any USB-aware operating system including Windows XP/7, Linux (kernel v2.4 or better), Apple (Apple OS X 10.4+), and other USB-aware operating systems. Check to make sure that USB support is enabled in the System BIOS and it is functioning properly in the operating system. This can be done by using Device Manager in Windows.

5. When a portable device (PD) is connected to a downstream port of the HUB7SSBA, the PD enumerates with either a SuperSpeed connection or a legacy USB connection (High-Speed, Full-Speed, or Low-Speed).
   a. If a SuperSpeed USB connection is established, the corresponding LED for that port will illuminate green.
   b. If a non-SuperSpeed USB connection is established, the corresponding LED for that port will illuminate yellow.
   c. The LEDs should remain unlit until a USB connection is detected.

6. When a downstream USB peripheral pulls more than 1500mA of power from ports 1,2,3,4,5, or 6, the overcurrent protection will shut down the port until the problem is resolved.

7. When a downstream USB peripheral pulls more than 2400mA of power from port 7, the overcurrent protection will shut down the port until the problem is removed.

8. On Windows 10, If the problem device is not removed from the HUB7SSBA within 3 seconds, the overcurrent event will be reported to the host as shown below:

9. Click on the “Power surge on the USB port” notification to open the prompt shown below:

10. The LED associated with the downstream port will turn off when in overcurrent shutdown; use the state of the LEDs to determine which port incurred the overcurrent shutdown. Disconnect your USB peripheral attached to the port in overcurrent shutdown. If the port remains unpowered, reset the HUB7SSBA by disconnecting the upstream host & external power and then reconnect them. Inspect the problem USB peripheral and replace, if necessary. Try connecting a different USB peripheral to the problem port. If the port remains unpowered after following the steps above, contact technical support for further assistance.

If these steps do not solve your problem, please call Sealevel’s Technical Support at +1 864-843-4343. Our technical support is free and available from 8:00 AM to 5:00 PM Eastern Time Monday through Friday. For email support, contact support@sealevel.com.
