3. In the Utility section, turn VS-EXPAND on (p. 60).
4. Switch on the power to the rst OCTA-CAPTURE unit.
5. Specify the same sampling frequency as that of the second unit (p. 67).
6. In order to digitally synchronize the two units, use a coaxial cable to connect the
second unit’s COAXIAL OUT (9/10) to the rst unit’s COAXIAL IN (9/10).
* If the Utility section’s DIGITAL setting is turned o, the sampling frequency will not switch.
Change the rst unit’s DIGITAL setting to “AUTO” (p. 60).
* Make sure that the Utility section’s VS-EXPAND setting is “OFF.”
7. Connect the second OCTA-CAPTURE unit to the computer.
Connect the two USB cables to USB ports that are near each other.
Windows 7/Windows Vista users
The driver will be installed automatically when you connect the OCTA-CAPTURE. Please wait.
Windows XP users
After you’ve made the connection, follow steps 10 through 13 on p. 20 to install the driver.
8. The procedure will dier depending on your system. Proceed as follows.
Windows users
If you’re using Windows, the two OCTA-CAPTURE units
must be connected to the same USB controller. Make sure
that “OK” is shown for the item VS EXPAND in the driver
settings (p. 69) of the OCTA-CAPTURE control panel.
If this does not indicate “OK,” proceed as directed below.
If “USB controller does not match” is shown:
Connect the second OCTA-CAPTURE unit to a dierent
USB port, and keep trying other USB ports until the
indication is “OK” or “Sampling frequency does not
match.”
* Alternatively, you can ensure that the two OCTA-CAP-
TURE units are connected to the same USB controller by
connecting them both to a USB 2.0 compliant hub.
If “Sampling frequency does not match” is shown:
Disconnect both USB cables from the computer, turn o
the power of the rst unit, and start again from step 4.
Connect each OCTA-CAPTURE unit to the same USB port.
If VS EXPAND is grayed out:
Disconnect both USB cables from the computer, turn o the power of both OCTA-CAPTURE units,
and start again from step 1.
