Table 11: Summagraphics ASCII Formats
Cursor Button Codes in ASCII Formats
When the cursor button code is included in an ASCII format, the character transmitted in
the format depends on the button pressed. Table 7 and Table 8 show which character will
be sent. Instructions in the previous sections show how to include or exclude the cursor
button character in certain of the ASCII formats.
Measurement Scales
You can choose either English or metric scaling for the coordinates you digitize. AccuTab
applies the required conversion factor before constructing a coordinate format for output.
The numbers appearing in coordinate formats depend on resolution. Table 12 shows how
the resolution settings affect the data in coordinate formats.
To set the measurement scale:
Custom Configuration Menu: Select a resolution in the “Resolution” column of Mode
Options.
GTCO Commands:
1. Send command IN for English or command MT for metric measurements.
2. Send command LR for 100 lpi/200 LPI/10 lpmm, command HR for 1000 lpi/40 lpmm
or command H1 for 4000 lpi/150 lpmm resolution.
Metric example: The distance between two points is 2032 counts in the 40 lpmm binary
format. Each count represents 0.025 mm (from Table 12). Then, 2032 counts x 0.025
mm/count = 50.8 mm.
