GLOSSARY
AC28
A high-speed adapter card that connects the Pamux bus to IBM PC/AT or compatible computers.
The AC28 is compatible with computers that feature a standard 8-MHz ISA bus. Each AC28 can
access up to 512 points of I/O. Four AC28s can be installed in one PC, supporting up to 2,048
points of I/O.
AC36
An adapter card that provides a Pamux bus interface for a TTL parallel port. It is compatible with
parallel-port devices for MULTIBUS, STD bus, and VME bus products. Each AC36 can access up to
512 points of I/O.
adapter card
A printed circuit board, often installed within a computer, used to transfer data between a bus
and a device.
analog
Describes data that can assume a continuous range of values, such as current, voltage, or
pressure readings. Opposite of digital.
analog point
An input or output with an analog value representing, for example, a value of 0 to 5 volts or a
temperature. Pamux analog modules feature 12-bit resolution.
API
Application program interface, a function in a programming library. The Pamux driver provides
APIs that allow easy access to the Pamux bus. Microsoft Windows also provides APIs for various
purposes, such as accessing serial ports and displaying message boxes.
B4
An addressable digital brain board that can control up to 32 input or output points in distributed I/
O applications. Any combination of Pamux B4 brain boards may be linked on a single Pamux bus
to control up to 512 points of analog and digital I/O.
B5
An addressable digital brain board that can control up to 16 input or output points in distributed I/
O applications. Any combination of Pamux B5 brain boards may be linked on a single Pamux bus
to control up to 512 points of analog and digital I/O.
