A sudden electrostatic discharge can destroy sensitive components. Proper packaging and earthing
rules must therefore be observed. Always take the following precautions.
•Transport boards and cards in electrostatically secure containers or bags.
•Keep electrostatically sensitive components in their containers until they arrive at an
electrostatically protected workplace.
•Only touch electrostatically sensitive components when you are properly earthed.
•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:
•Cover workstations with approved antistatic material. Always wear a wrist strap connected to
the workplace as well as properly grounded tools and equipment.
•Use antistatic mats, heel straps, or air ionizers for more protection.
•Always handle electrostatically sensitive components by their edge or by their casing.
•Avoid contact with pins, leads, or circuitry.
•Turn off power and input signals before inserting and removing connectors or connecting
test equipment.
•Keep the work area free of non-conductive materials such as ordinary plastic assembly aids
and Styrofoam.
•Use field service tools such as cutters, screwdrivers, and vacuum cleaners which are
conductive.
•Always place drives and boards PCB-assembly-side down on the foam.

Hardware Description
USB Ports
The HUB4SSBA integrates SeaLATCH USB 3.1 Gen 1 ports, which are fully compatible with standard USB
cables. When used with the optional USB cable with a SeaLATCH USB 3.1 Gen 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 Gen 1 type B locking connector and standard USB 3.1 Gen 1 type B port is shown
below:
The HUB4SSBA’s four SeaLATCH USB 3.1 Gen 1 type A locking USB connectors can secure USB peripherals
to the hub in the same way. Two of the SeaLATCH USB 3.1 Gen 1 type A ports are shown below. Each of
the four downstream type A USB ports provides up to 1500mA to USB peripherals with port four providing
up to 2400mA.
Each downstream port of the HUB4SSBA has its own transaction translator to provide the best USB
performance no matter what class of USB device is connected to it.
1500mA Ports:
Each HUB4SSBA has three 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 HUB4SSBA 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).

12
© Sealevel Systems, Inc. HUB4SSBA Manual | SL9184 10/2023
Status LEDs
Each downstream port has a status LED that is visible from the front of the HUB4SSBA 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 Gen 1 Connection with Host (Green) – Lights when a USB 3.1 Gen 1 connection is
established with the upstream host.
Hub Power Modes
External Power
The HUB4SSBA can be ordered with a desktop power supply (Item# TR152) that outputs 24VDC @
2.71A, providing up to 1500mA to each downstream USB port and up to 2400mA to downstream port
4. 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 the
hub. The HUB4SSBA accepts a wide input voltage range from 9VDC to 30VDC for use with alternative
power supplies.
When the HUB4SSBA is powered via external power, the hub is configured as a self-powered device
that consumes less than 1 mA of upstream VBUS current. In this self-powered mode, each downstream
port is configured as a Charging Downstream Port (CDP) capable of delivering up to 1500mA with port
4 capable of delivering up to 2400mA.
When external power is used to supply the hub, the HUB4SSBA will automatically reset and
switch to a bus-powered configuration if the external power supply drops below 9VDC (8.75v
typical) or if it rises above 30VDC (33v typical). If either of these two power supply conditions
occur, the HUB4SSBA will perform a reset and re-enumerate as a bus-powered device. When
the external power supply returns to a nominal voltage, the HUB4SSBA will reset back into
external-powered mode.

13
© Sealevel Systems, Inc. HUB4SSBA Manual | SL9184 10/2023
Bus Power
The HUB4SSBA can also be powered via the upstream USB connection to the host. In this mode, the
HUB4SSBA draws all its power from the host computer's USB interface. It does not need a separate
power connection.
When the HUB4SSBA is powered via bus power, the hub is configured as a bus-powered device. In this
mode, each downstream port has its current limit reduced and is configured as a Standard Downstream
Port (SDP). After configuration, the bus-powered hub must consume no more than 900mA of the
upstream VBUS current (500mA if the hub is connected to the host through a legacy USB 2.0/1.1 port).
Many devices may require more power than the bus-powered hub can provide and may not work while
the hub is in the bus-powered mode. This is especially true of USB 3.0/3.1/3.2 devices. If a device fails
to enumerate in bus-powered mode, it may be attempting to draw too much current out of the upstream
USB connection. If this happens, remove the device, apply external power, and reconnect the device.
The bus-powered mode is ideal for situations where external power cannot be applied, (or is
inconvenient to do so).
To configure the HUB4SSBA as a bus-powered device, the upstream host must be connected
to the host port of the HUB4SSBA.

SeaLATCH® USB 3.1 Gen 1
The HUB4SSBA integrates SeaLATCH USB 3.1 Gen 1 ports, which are fully compatible with standard USB
cables. When used with the optional USB cable (Item# CA748) with a SeaLATCH USB 3.1 Gen 1 type B
connector, the metal thumbscrew provides a secure metal-to-metal connection to the hub and prevents
accidental cable disconnection.
The hub’s four SeaLATCH type A USB 3.1 Gen 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 HUB4SSBA with SeaLATCH equipped Sealevel I/O devices are shown below:

SeaLATCH Locking USB 3.1 Gen 1 Cables
SeaLATCH locking USB 3.1 Gen 1 cables integrate a small thumbscrew into each USB connector.
SeaLATCH USB 3.1 Gen 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 Gen
1 cables are available in three configurations.

Appendix A – Troubleshooting
The HUB4SSBA 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 and Windows 11.
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 and Windows 11, 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:

18
© Sealevel Systems, Inc. HUB4SSBA Manual | SL9184 10/2023
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.
