Host interfaces for ITC-16
and EPC 9
The ITC-16 is an external
rack-mountable data acquisition unit that is attached to the computer using
a dedicated host interface. A major advantage of this design is the
capability to use the analog front end (ITC-16 or EPC-9) with a variety of
available host interfaces. Most data acquisition devices are printed
circuit boards installed directly into the computer. These devices
become obsolete with the computer platform that they are attached to.
Moving the ITC-16 from one computer platform to another
is a simple matter of using the appropriate host interface, and installing
compatible software. Utilizing the same hardware when changing
computer platforms provides a cost effective upgrade path to newer computer
technologies without sacrificing your initial investment
In keeping with this design philosophy
InstruTECH host interfaces are available for the discontinued ITC-16 and EPC-9.
A
note about Macintosh G5 computers
Apple has once again
changed the PCI bus on their Power Mac G5 desktop computers. The
latest release, as of November 2005, use’s a PCI Express bus architecture.
The PCI Express bus IS NOT compatible with either the PCI-16 or the
PCI-16V3 host interface. The only host interface choice would be the
USB-16. This would also be true for iMAC G5, MAC mini and laptop
computers. The new Intel based Mac computers will also use the PCI
Express bus architecture.
Power Mac G5 computers
before November 2005, used a 3.3 Volt PCI /PCI-X bus architecture.
For these systems either the PCI-16V3 or the USB-16 host interface would be
required.
A
note about PC computers
There are many PC computers
manufactures, which makes it impossible for us to know the exact bus
architecture that is currently available. Many as still supporting
the original PCI bus, some are using a mixed PCI bus scheme and others have
adopted the new PCI Express standard all together. Please check the
exact bus specifications of your particular system before selecting a host
interface.
A
note about USB2.0
USB 2.0 comes in three speed
settings. The USB-16 requires a high-speed (480 Mbps) connection.
Most newer computer systems are supplied with multiple USB 2.0 ports but
only some of these ports are configured for high-speed operation. The
USB-16 will work on the slower ports but the transfer rates will be greatly
affected.
If your computer system
does not have high-speed USB2.0 ports then a USB2.0 adapter may be
used. These adapters are available in many different bus
configurations (PCI, PC Slot, etc).

The PCI-16 host interface card is a short
form factor, 32-bit, 33 MHz 5 Volt PCI bus plug in card. The PCI-16
is compatible with Apple, PC, and other computer systems that feature a
5 Volt PCI Bus. Please note that the PCI-16 can only be physically
connected to a 5 Volt or Universal PCI bus connector.

The
PCI-16V3 host interface card is a short form factor, 32-bit, 33 MHz
3.3 Volt PCI bus plug in card. The PCI-16V3 is compatible with Apple
G5, PC, and other computer systems that feature a 3.3 Volt PCI Bus.
Please note that the PCI-16V3 can only be physically connected to a
3.3 Volt or Universal PCI bus connector.

The USB-16 host interface
is a USB 2.0 high-speed (480 Mbps) interface for Apple, PC, and other
computer systems that feature USB 2.0 high-speed ports. Since the
USB-16 is an external adapter “box” it can be used with all ITC-16’s and
EPC 9 amplifiers produced.
An extra feature of the
USB-16 is the addition of sixteen asynchronous digital input and output
lines.
