Installing the 82357A

Step 3: Connecting the 82357A

2

Observe the LEDs.

 Observe the LEDs on the 82357A for at least 10 

seconds. See 

Chapter 2 - Using the 82357A 

for a description of the 

normal LED sequence with an initial installation of an 82357A.

a

Initially, only the red FAIL LED should be ON. After a few seconds, 
all three LEDs should be ON. All three LEDs ON shows the 
82357A has been successfully installed, but is not yet configured 
for use with the Agilent IO Libraries Suite. 

b

If 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 82357A 

for diagnostics information.

c

If all three LEDs are 

still

 ON after 10 seconds, go to “Observing 

Windows Plug and Play Manager Sequence (Windows XP Only)”. 

Connecting the 82357A to a USB Hub

This section shows steps to connect the 82357A to a USB port on your PC 
via a standard USB hub. 

1

Plug the power adapter into the hub and into an electrical outlet. 
Make sure the hub is operating in self-powered mode. For example, 
the following figure shows a 4-port self-powered USB hub with two 
82357A USB/GPIB Interface Converters connected.

2

Make sure your PC is ON. Connect the USB cable of the USB hub 
to any available USB port on your PC.

3

Plug at least one 82357A USB/GPIB Interface Converter into the 
port(s) on the USB hub. It is not necessary to connect GPIB 
instruments to any 82357A at this time.

NOTE

Any USB hub used with the 82357A 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.
