Operating Information
CRT GRAPHICS
INTRODUCTION
The HP 8756A CRT Graphics are also controlled by the 8756
SYSTEM INTERFACE. The Graphics commands are mostly a subset of
the Hewlett-Packard Graphics Language (HP-GL), shown in Table
3-4. This HP-GL subset allows the HP 8756A to understand most
HP desktop computer plotter output commands. The HP 8756A CRT
Graphics characters used for labeling are shown in Table 3-5,
HP 8756A Modified ASCII Code Conversion Table. These modified
ASCII characters are available only when using the "LB" command
explicitly: most desktop computer plotter commands use the
Standard ASCII Code character set.
The address of the CRT Graphics is the HP 8756A address minus
1: since the default address of the HP 8756A is 16 decimal, the
default address of the CRT is 15 decimal. An example of
addressing the CRT Graphics using the default addresses is:
1. Address device 16 (the HP-IB of the HP 8756A): send the
characters "PT15:" or "PT15 [cr] [lf] ".
2. Address device 17 (the 8756 SYSTEM INTERFACE); send Table 4
commands.
3. Address device 16. This returns the HP 8756A to its normal
HP-IB operation.
4. Subsequent addressing of device 17 will send commands to
the CRT Graphics.
NOTE
All CRT Graphics Commands must be terainated with a
semicolon •;• or a •[lf]•; the character •[cr]• is
ignored. For the syntax examples shown below, [term)
= either of these terminators.
