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.

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.
