Installing the Agilent 82357B
This chapter shows a suggested five- step process to install
the 82357B and the Agilent IO Libraries Suite, to connect
the 82357B to your PC and to program GPIB instruments via
the 82357B.

1 Installing the Agilent 82357B
Step 1: Checking Your Shipment
Your 82357B USB/GPIB Interface shipment should include
the items shown in Figure 1- 1. If any item is missing or
damaged, keep the shipping materials and contact Agilent
Technologies. See “Contacting Agilent” on page 37 later in
this guide for addresses and telephone numbers.
As you check the shipment items, verify that the 82357B
serial number at the bottom of the 82357B matches the
serial number shown on the serial number label of the
82357B Kit Box and on the 82357B Certificate of
Calibration. If the Serial Numbers do not match, contact
Agilent. If all Serial Numbers match, you may want to record
the Serial Number for future reference.

Step 2: Installing Agilent IO Libraries Suite
This section describes how to install the Agilent IO Libraries
Suite on your PC. The Agilent IO Libraries Suite is a
collection of libraries and utilities that gives you the ability
to use your instruments from instrument control software.
You should install the Agilent IO Libraries Suite as your first
step before installing the hardware because it installs the
necessary software and drivers to control your instruments.
If possible, always use the most recent version of the Agilent
IO Libraries Suite. This version supports the newest
interfaces and operating systems, and has the most
advanced features.
1Verify that your PC meets the minimum system
requirements. Refer to the IO Libraries Web page at
www.agilent.com/find/iosuite or the IO Libraries
Suite Readme.
2Close all applications on your computer. Insert the Agilent
Automation- Ready CD in your CD- ROM drive or download
and install the IO Libraries software from
www.agilent.com/find/iosuite.
3Follow the instructions as prompted during the
installation. You can select either a Typical or a Custom
installation:
•Typical - In most cases, you can select the Typical
installation which installs the IO Libraries Suite using
the recommended settings.
NOTE
You must have Administrator privileges to install Agilent IO Libraries Suite
Connection Expert.

•Custom - Select the Custom installation to:
aInstall the IO Libraries Suite in another directory
(for 32- bit operating systems only).
bSave disk space by not installing interface manuals.
cUse Agilent 32- bit VISA with another vendor's VISA
on the same PC in side- by- side mode. Details on
side- by- side mode are available at
www.agilent.com/find/side- by- side- install or in the
IO Libraries Suite help.
4After the IO Libraries suite is successfully installed, you
will see the IO icon on the Windows®taskbar
notification area.

Step 3: Connecting the 82357B
After the Agilent IO Libraries Suite software has been
installed, you can connect the 82357B to any USB port on
your PC or you can connect the 82357B via standard USB
hubs.
82357B hardware description
The Agilent 82357B provides a direct interface connection
from your PC USB port to GPIB instruments. The 82357B
includes an attached USB cable that is USB 2.0 compliant.
This cable is shielded and the connector is specified for up
to 1,500 insertions. An 82357B can be directly connected to
a single GPIB instrument or up to 14 GPIB instruments via
GPIB cables. Up to four 82357B converters may be
connected to your PC via standard USB hubs.

NOTE
If the Agilent IO Libraries Suite software have not been installed on your
PC, STOP. Install the libraries (see Step 2: Installing Agilent IO Libraries
Suite).

Connecting the 82357B to your PC
This section shows steps to connect the 82357B to a USB
port on your PC or to your PC via a USB Hub.
1Connect to a USB Port. Make sure the PC is ON and
plug the 82357B USB cable into any available USB port
on your PC. Do not connect the 82357B to GPIB
instruments at this time.
Figure 1-4 Connecting the 82357B to Your PC
2Observe the LEDs. Observe the LEDs on the 82357B for
at least 10 seconds. See Chapter 2, “Using the Agilent
82357B” for a description of the normal LED sequence
during an initial installation of the 82357B.
aInitially, only the red FAIL LED should be ON. After a
few seconds, all three LEDs should be ON. When all
three LEDs are ON, this shows that the 82357B has
been successfully installed.
bIf all three LEDs are not ON after 10 seconds and all
Windows Plug- and- Play Manager activity has ceased,
STOP. See Chapter 3, “Troubleshooting the Agilent
82357B” for diagnostics information.

Connecting the 82357B to a USB hub
This section shows steps to connect the 82357B to a USB
port on your PC via a standard USB hub.
1Plug the power adapter into the hub and into an electrical
outlet. Make sure the hub is operating in self- powered
mode. Figure 1- 5 shows a 4- port self- powered USB hub
with two 82357B USB/GPIB Interfaces connected.
2Make sure your PC is ON. Connect the USB cable of the
USB hub to any available USB port on your PC.
3Plug at least one 82357B USB/GPIB Interface into the
port of the USB hub. It is not necessary to connect GPIB
instruments to any 82357B at this time.
Figure 1-5 Connecting the 82357B to a USB Hub
NOTE
Any USB hub used with the 82357B MUST be self-powered (must not be
bus-powered or powered from the USB bus). Also, be sure to check the
applicable USB hub documentation for hub operating parameters, such as
power requirements and maximum length of USB cables.
