14 MVS-8600 Hardware Manual
MVS-8601 and MVS-8602 boards are designed with a 64-bit data path so when you plug
an MVS-8601 or MVS-8602 into a 32-bit PCI slot some of the pins are not used. The
unused pins hang out over the end of the connector. See Figure 2.

PCI Bus Speed
The PCI bus clock speed can be 33 MHz or 66 MHz depending on the PC motherboard
you are using. You cannot tell the bus speed by looking at the card slots. You must read
the motherboard specifications to find this information. MVS-8601 and MVS-8602 frame
grabbers will run at either 33 MHz or 66 MHz. You do not need to make any changes to
the frame grabber board. It adapts automatically to the PCI bus clock speed and runs
faster at 66 MHz that at 33 MHz.
Note For best performance, place the MVS-8601 or MVS-8602 in a
64-bit/66 MHz slot.
