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

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.
