This virtual HP-IL device emulates a HP7470A plotter.
HP-IL configuration:
Accessory ID | 0x60 |
Default Address | 5 |
Device ID | HP7470A |
This virtual HP-IL device emulates a HP7470A plotter. All HP-GL commands of the HP7470A plotter (HP-IL version) are supported. In addition the HP-GL commands AA, AR and CI are supported which were only available on the RS232C version of the HP7470A.
Note:The plotter tab requires the program emu7470 which is part of version 1.7.7 or later of the . The default configuration of pyILPER does not contain a plotter tab. You have to add this device in the Virtual HP-IL device configuration.
The paper size settings in the pyILPER configuration controls the papsersize setting of the plotter as well as the page size of the PDF output.
The plotter tab has the following controls:
A yellow error led indicates a HPGL-Error. Use the status button to obtain information about the error code and additional diagnostics. If the error led is red then the external plotter emulator program emu7470 could not be started or had crashed.
Digitizing is initiated by a HP-GL DI command. This puts the GUI into digitizing mode. A cross-hair cursor appears and you can digitize coordinates. The Enter button registers the coordinates of the last clicked location. They are now available for the HP-GL OD command.
The Clear button cancels digitizing mode. No coordinate is registered.
In digitizing mode the coordinates of the clicked locations are shown at the right side of the tab. In addition numeric values of the coordinates can be entered as well.
The location of both scaling points are displayed and the GUI enters digitizing mode (see above). You may digitize now a new position for P1. Register the location of P1 with the ENTER button and digitize the location of P2. After registration of P2 the digitizing mode is finished and the new positions of the scaling points are applied. The digitizing mode can be cancelled with the Clear button at any time.
The plotter emulator should provide reasonable results for proper HP-GL commands. A compatible behavior in error conditions needs improvements.
