- Howdy,
-
- I have a HP plotter, model 9872C which I would like to connect to
- an IBM PC compatible.
-
- The problem is the interfacing.
- The HP has a connector for a HPIB aka GPIB aka IEEE-448 aka IEC-625 bus.
- This is a bus system, whereas my PC has a simple IO port, being
- the Centronics parallel port.
-
- I was wondering if there is any chance that I can interface my
- computer and plotter.
- I was thinking along this kinda line:
- Suppose I make a conversion cable between the centronics and the
- HPIB pin layout.
- Then I write a simple piece of code that sends data to the parallel port
- which will setup my system such that the computer is the only talker,
- and the plotter is the only listener (listen-only).
- Then, I hope, I should be able to use regular plotter drivers from
- standard PC software to drive my plotter.
-
- There are several things that may screw up my plan, as outlined above.
- First of all, some pins on GPIB may have no centronics counterpart,
- or visa versa.
- Second, it may be that every now and then GPIB bus commands must be
- xmitted, so that a pre configuring the system before using DOS applications
- won't do.
- Third, it may be the case that the HP9872C does not use the common
- plotter language HP-GL, as I was hoping.
- This will mean that regular DOS drivers won't be able to cope with
- the plotter.
-
- If you know how to connect GPIB devices to a centronics port,
- or, maybe, you know for a fact that the thing I want is unviable,
- please drop me line,
-
- Thanx in advance,
-
- Bram Stolk
