Pollution Degree Description
A measure of the contaminants that could occur in the environment
around and within a prod uct. Typically the internal environment inside
a product is considered to be the same as the external. Products should
be used only in the environment for which they are rated.
Pollution Degree 1. No pollution or only dry, nonconductive
pollution occurs. Products in this category are generally
encapsulated, hermetically sealed, or located in clean rooms.
Pollution Degree 2. Normally only dry, no nconductive pollution
occurs. Occasionally a temporary conductivity that is caused
by condensation must be expected. This location is a typical
office/home environment. Temporary condensation occurs only
when the p roduct is out of service.

Pollution Degree 3. Co nductive pollution, or dry, nonco nductive
pollution that becomes conductive due to condensation . These
are sheltered locations w here neither temperature nor humidity
is controlled. The area is protected from direct sunshine, rain, or
direct wind.
Pollution Degree 4. Pollution that generates persistent con ductivity
through conductive dust, rain, or snow. Typical outdoor locations.

Installation
Connecting Power
You can connect power to the adapter in one of two ways:
From a USB host port
From the optional external power supply
Connecting USB Power
To apply power to your adapter from a USB host port, do the following
procedure:
1. Connect the device end of a USB cable to the USB Device port
on the rear panel of the adapter.
2. Connect the host end of the USB cable to a USB Host port on the
equipment that is to provide power (typically the instrument being
controlled or a PC).
3. Verify that the Power LED lights and that the USB and Adapter
Status LEDs turn on and then off. This indicates that the adapter
is initializing correctly.

Connecting the External Power Supply
To apply power to your adapter from the optional AC power unit, do
the following procedure:
1. Connect the output power cable from the power unit to the 5 VDC
connector on the rear panel of the adapter.
2. Connect one end of the optional pow er cord to the external power
supply.

Connecting Cables
NOTE. The following cables can be connected while the instruments are
powered on.
To connect the TEK-USB-488 GPIB to USB Adapter to USB and GPIB
cables, do the f ollowing procedure:
1. Connect a GPIB cable from the GPIB controller to the GPIB po rt
on the adapter.
2. Connect a USB cable from the Device port on the instrument to the
Host port on the adapter.
14 TEK-USB-488 GPIB to USB Adapter User Manual
Setting the GPIB Address
The default GPIB address of the adapter is 1. You have to use the
default GPIB address for the adapter if you use it with instruments that
are not manufactured by Tektronix, or with older Tektronix instruments
that are not designed to support the USB protocol and USB extensions
required for setting the GPIB address of the adapter.
If you connect the Tek-USB-488 GPIB to USB Adapter to a Tektronix
USBTMC-USB488 compliant instrument desig ned to support the
adapter, such as a DPO4000 Series instrument, you can set the address
to a value from 1 through 30 using the menu system of the instrument.
To change the GPIB address from an instrument designed to support the
adapter, do the following procedure:
1. Locate the GPIB control menu on the instrument being attached.
2. Use the appropriate control to select the Talk/Listen address that
you wan t. T he instrument automatically disables and enables the
USB port so that the new address is recog nized .
3. Communicate with the instrument attached to the adapter using the
control program running on your GPIB con troller.

The f ollowing parameter assumptions are made:
GPIB secondary addressing is not supported.
The default GPIB primary address i s 1. The GPIB p rimary
address can only be changed from a connected Tektronix
USBTMC-USB488 compliant instrument designed to support the
TEK-USB-488 GPIB to USB Adap ter, such as a DPO4000 Series
oscilloscope.
The GPIB Program Message Terminator (PM T ) is the GPIB end of
input (EOI) line and is not configurable. Messages that assert EO I
concurrent with a new line (hexadecimal 0a) character as the last
data byte are supported. This means th at both EOI and EOI NL
program message terminations are supported and that the NL-only
termination is not supported.
USB hubs are not supported. You can connect only one
USBTMC-USB488 compliant instrument to the USB Host port of
the adapter at any t im e.
The GPIB on/off state is online when there is an active
USBTMC-USB488 connection. You cannot change the GPIB
on/off state after the conn ection is established.
