5. Repeat the steps to attach another TEMPpoint, VOLTpoint, or MEASURpoint instrument
to the host computer, if desired.
Connecting to an Expansion Hub
Expansion hubs are powered by their own external power supply. Theoretically, you can
connect up to five expansion hubs to a USB port on the host computer. However, the practical
number of instruments that you can connect to a single USB port depends on the throughput
you want to achieve. Each of the hubs supports up to four instruments.
To connect multiple TEMPpoint, VOLTpoint, or MEASURpoint instruments to an expansion
hub, do the following:
1. Make sure that you have attached a power supply to the instrument.
2. Attach one end of the USB cable to the instrument and the other end of the USB cable to
an expansion hub.
3. Connect the power supply for the expansion hub to an external power supply.
4. Connect the expansion hub to the USB port on the host computer using another USB
cable.
The operating system automatically detects the instrument and starts the Found New Hardware
wizard.
5. Click Next and/or Finish in the wizard. Once the firmware is loaded, the wizard restarts
to initiate the firmware to accept commands. Click Next and/or Finish again.
If the power supply and the instrument are attached correctly, the USB LED, shown in
page
34, turns green.
6. Repeat these steps until you have attached the number of expansion hubs (up to five) and
instruments (up to four per hub) that you require. Refer to
The operating system automatically detects the instruments as they are installed.
