BASICA, BASIC compiler and Quick-BASIC are supported as standard languages. C
and Pascal language support packages can be ordered separately as PCL-748-C and
PCL-748-P.
The software can change the PC printer port to an IEEE-488 device. The PrtSc (print
screen) key, all print statements, word processing and spreadsheet programs that use
printer driver in BIOS can use IEEE-488 printers.
* High speed direct memory access (DMA) with the ability to handle 64K byte
arrays.
* Programmable system controller, active controller or device functions.
* All device functions, addresses, interrupt conditions, and parallel poll responses are
programmable.
* Automatic initialization. Interface parameters are set to default when starting using
the interface. Parameters can still be changed by calling the initialization routine.
* DIP switch selectable wait states (0/2/4/6 wait states) to ensure the compatibility to
very high speed PC's.
* PCL-848A offers the connectors of the IEEE-488 standard while PCL-848B uses
the 25 pin D type connectors for the IEC-625 standard.
* Each device on the IEEE-488 bus can be assigned with its own terminator.
Information in this manual is given at several levels of detail and is organized to allow
you to work through the TUTORIAL, PROGRAHMING REFERENCE and
PROGRAMMING TECHNIQUES sections.
If you have no IEEE-488 experience, go to Section 9. after this section.
The IEEE-488 TUTORIAL in Section 9. is designed to give you a thorough under-
standing of how the IEEE-488 General Purpose Interface Bus (GP-IB) works. Topics
in the TUTORIAL should be read in sequence if you have no IEEE-488 background
and intend to write application programs. With a solid understanding of the basic
IEEE-488 concepts, followed by returning to the PROGRAMMING REFERENCE,
and the PROGRAMMING TECHNIQUES, you should be able to program almost
any IEEE-488 bus system without interface problems.
