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
With industrial and OEM applications increasingly adding USB devices, the need for more USB ports becomes a
necessity. The HUB4PH is a powered USB 2.0 4-port hub that is perfect for adding high-speed USB ports to
industrial computing platforms.
The HUB4PH adds support for the USB 2.0 Battery Charging Specification version BC1.2 by the addition of a single
Charging Downstream Port (CDP). The remaining three ports are Standard Downstream Ports (SDP).
USB 2.0 Standard Downstream Port (SDP)
An SDP is a traditional USB 2.0 port that provides for data communications as well as a minimum of 500mA of
power. The host controller must be active to allow charging and the attached device will charge at a slower rate
due to the limited power available.
USB 2.0 Charging Downstream Port (CDP)
A CDP is a USB 2.0 port that provides for data communications and has the enhanced capability to provide up to
1.5A to the attached downstream device. For devices compatible with the USB Battery Charging BC1.2
specification a handshaking process occurs during attachment that allows the device to determine the amount
of power available. Once a CDP port is detected the device is then aware that extra power is available and can be
used to charge the device faster and at a higher rate.
The HUB4PH is USB 2.0 compliant, providing a full 480M bps data rate to the host, and is backwards compatible
with USB 1.1 and 1.0 devices. Additionally, port one is configured as a USB Battery Charging Specification BC1.2
Compliant Charging Downstream Port (CDP) supplying up to 1.5A of current. The powered hub includes a wall-
mount AC adapter that supplies 1.5A to port 1 and a full 500mA to ports 2 through 4. The hub is housed in a
rugged plastic enclosure and a status LED indicates proper connection to the host.
Additionally, the HUB4PH-KT and HUB4PH-OEM versions both include a power cable that sources +5VDC power
from a standard hard drive connector. For the –KT and –OEM versions all four ports are configured as USB Battery
Charging Specification BC1.2 Compliant Charging Downstream Ports (CDP) and supplies a full 1.5A to each
attached USB peripheral. The standard operating temperature range is 0°C to 70°C and extended temperature
range (-40°C to +85°C) is optional.

SeaLATCH® USB
The HUB4PH and HUB4PH-KT integrate Sealevel’s SeaLATCH locking USB ports, which are fully compatible with
standard USB cables. When used with SeaLATCH locking USB cables, the metal thumbscrew provides a secure
metal-to-metal connection to the hub and prevents accidental cable disconnection.
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 HUB4PH with SeaLATCH equipped Sealevel I/O devices are shown below.
