Glossary: Product Features Explained
Universal PCI
Universal products allow compatibility with both 3.3 Volt and 5 Volt PCI systems. This ensures that Brainboxes
universal card range is backward compatible with older systems and works with all new PCI systems.

Autogating
When the device is set to half duplex mode, transmitted and received data is sent across the same signal lines.
Autogating means the Brainboxes card knows when to 'listen' for data and when to transmit data, with a quick
and automatic hardware switch between the 2 modes. This is much faster than software switching and ensures
no data loss due to turnaround delay.

Opto Isolation
Optical isolation provides greater protection from electrical current surges to both the card itself and the PC. It
improves noise immunity by isolating the PC from the card’s transmit ground.
Opto-Isolation: ±1500Volt DC/ 1000Volts AC

PCI Compliant
All Brainboxes Universal PCI cards are fully PCI version 3.0 compliant, in accordance with the PCI-Special Interest
Group (PCI-SIG).
Group (PCI-SIG).
Large FIFO
FIFO means First In First Out, a FIFO is memory space on the Brainboxes card. A larger FIFO allows more memory
space for buffering data, so calls to the computer processor are less frequent. This significantly increases data
throughput and improves CPU availability for other applications.

4 Layer PCB
Printed Circuit Board with 4 layers of circuitry complies with the PCI SIG best practice guideline and ensures a more
reliable card. 1 layer is for power and 1 for ground which leads to greater EMC shielding for the signals. This
ultimately gives greater signal integrity for sensitive timing applications.

Surface Mount Components
Most components on a Brainboxes card are placed by a surface mount machine. The surface mount machine
allows for highly accurate and fast production of Brainboxes cards. Orders can be met quickly, reliably and with
outstanding quality.

Capacitors
As required by the PCI-SIG all Brainboxes cards have capacitors connected to all the power pins on the PCI
connector, near to the connector. This ensures that the electrical power rails on the Brainboxes card stay at the
right voltage, regardless of the power demands placed on them. Data signals keep their integrity.
