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.
•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
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 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.

Introduction
The HUB7M is a high speed 7-port USB 2.0 hub that is ideal for adding USB ports to a SeaI/O data acquisition
“stack” or a Relio R1000 embedded solid-state industrial computer. The HUB7M includes an industrial grade wall-
mount power supply that outputs 12VDC @ 2.5A, providing a full 500mA to each attached USB peripheral.
Supported in all USB aware operating systems, the HUB7M requires no separate software drivers and is easy to
install.
The HUB7M integrates SeaLATCH™ USB ports, which are fully compatible with standard USB cables. When used
with the included USB cable with a SeaLATCH type B USB 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 connectors can secure USB peripherals to the hub in the same way. Additionally, a highly retentive
type B USB connector helps prevent unintentional separation from a standard USB cable.
Features
•Includes 7 USB downstream ports with 500mA available per port
•SeaLATCH USB connectors provide locking connection
•Status LEDs indicate external power, connection to host, and fault condition
•High-retention USB type “B” connector prevents accidental disconnection of standard USB cable
•USB 2.0 compliant and backwards compatible with USB 1.1 and 1.0 devices
•No drives required for Windows 98SE/ME/2000/XP/Vista/7™ and Linux kernel v2.4 operating
systems

Installation
Windows 98/ME/2000/XP/Vista™ Operating Systems
1. The HUB7M is fully supported as a generic USB hub device in Windows 98/ME/2000/XP/Vista/7™
operating systems and requires no separate driver.
2. Simply connect the included wall-mount power supply to the HUB7M and connect to an AC outlet.
When the unit is successfully powered, the green LED will light.
3. Using the included SeaLATCH USB device cable, plug the HUB7M into an available USB port on your
host system.
4. The ‘Found New Hardware’ screen will appear, and the hub will be automatically recognized as a
generic USB hub device. When the unit is successfully recognized by the operating system, the
yellow LED will light. During data transfers, this light will blink.
5. The hub is ready to use when you see the screen ‘Your USB hub is installed and ready to use.’
Windows NT is not USB aware and thus cannot support this device.
LINUX SUPPORT
USB devices are supported in Linux kernel v2.4 or better. Refer to the help files included with your Linux
distribution for specific instructions on adding generic USB hub devices.

Hardware Description
USB Ports
The HUB7M integrates SeaLATCH USB ports, which are fully compatible with standard USB cables. When used
with the included USB cable with a SeaLATCH type B USB connector, the metal thumbscrew provides a secure
metal-to-metal connection to the hub and prevents accidental cable disconnection.
Additionally, a highly retentive type B USB connector helps prevent unintentional separation from a standard
USB cable. The SeaLATCH type B locking connector and high retention type B port are shown below.
The hub’s seven SeaLATCH type A locking USB connectors can secure USB peripherals to the hub in the same
way. Two of the SeaLATCH type A USB ports are shown below. Each of the seven downstream type A USB ports
provides a full 500mA to USB peripherals.

HARDWARE DESCRIPTION, CONTINUED
Status LEDs
Status LEDs are also included on the front of the HUB7M module to indicate the following information:
•ENABLE (Yellow) –Lights when the USB hub is enumerated by the host system.
•FAULT (Red) –Lights when there is a problem with a downstream USB port. Disconnect the
downstream devices one at a time until the status returns to normal.
•EXT POWER (Green) –Indicates the external power supply is properly connected to the hub and an
AC power source.
External Power
The HUB7M includes an industrial grade wall-mount power supply (Item# TR123) that outputs 12VDC @ 2.5A.
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.

SeaLATCH® USB
The HUB7M integrates SeaLATCH USB ports, which are fully compatible with standard USB cables. When used
with the included USB cable (Item# CA356) 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 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 HUB7M with SeaLATCH equipped Sealevel I/O devices are shown below:
