This section shows steps to connect the 82357B 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. Figure 1- 5 shows a 4- port self- powered USB hub
with two 82357B USB/GPIB Interfaces 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 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.
