16 Bit Parallel I/O Expansion Card
This product has been discontinued.
For a wide range of parallel input/output applications.
The 16 Bit Parallel I/O Expansion Card provides two separate 16 bit input/output ports for a RISC OS based computer with an expansion backplane and RISC OS 3.1 or later.
Each port can be configured as either one 16 bit input or output port with two handshake lines, or as two separate 8 bit input or output ports each with two handshake lines. All the data and handshake lines are fully buffered.
Other facilities include four 16 bit counter/timers, two 8 bit shift registers and eight interrupt inputs.
Two standard 40 pin ribbon cable connectors are provided on the rear panel. Each 8 bit port has the same pin assignments as the User Port of the original BBC Microcomputer and subsequent Single and Acorn Double Width I/O Expansion Cards. The IM92 26/32 Bit Neutral (IYONIX pc compatible) Version of the UserPort Module enables them to be software compatible.
The maximum number of 16 Bit Parallel I/O Expansion Cards that can be fitted in a RISC OS based computer is limited only by the number of unused expansion card slots.
Areas of application in science and industry are almost infinite and include measurement and control and high speed data input and output (greater than 200,000 16 bit values per second).
A RISC OS based computer fitted with two 16 bit Parallel I/O Expansion Cards has been used to control an optical (0.4m Newtonian/ Cassegrain) telescope at the University of Birmingham.
Full software support is provided by the Intelligent Interfaces 16BitPIO Module and BASIC and Fortran libaries.
