A.1.1 RS-232 Hardware Interface
The Summagrid III’s interfacing hardware complies with the EIA (Electronic
Industries Association) RS-232C standard. The interface is bidirectional,
asynchronous and serial. It is capable of communicating in full duplex and uses the
ASCII seven-bit data code.

Appendix D GTCO Format Emulation
The Summagrid IV can emulate the GTCO output format. This chapter provides the binary
and ASCII information for the GTCO output format.
D.1 Summagrid IV Interfacing Hardware
D.1.1 Overview
Summagrid IV report formats conform to GTCO 5A standards. To accommodate the
emulation needs, choose the GTCO format to be in ASCII or packed binary.
D.1.2 ASCII BCD Report Format
Within the ASCII BCD report format, select:
Output to be in counts, inches or millimeters.
In units of measure, also choose the format to include a decimal or not.
This does not change the value of the coordinate. For example, 10.123
inches can be reported as either 10123 or 10.123.
Each report to terminate with a <CR><LF> or just a <CR>.
Delimiter to be any ASCII character. (The default is a comma.)

Appendix E CalComp Format Emulation
The Summagrid IV can emulate the CalComp 9100 output format. This chapter provides
the binary and ASCII information for the CalComp output format.
E.1 CalComp Output Format
E.1.1 Overview
Summagrid IV report formats conform to CalComp 9100 standards. To
accommodate the emulation needs, choose from one of four ASCII formats or a
packed binary format.
E.1.2 ASCII BCD Report Formats
Within the ASCII BCD report format, select:
Output to be in counts, inches or millimeters.
In units of measure, also choose the format to include a decimal or not.
This does not change the value of the coordinate. For example, 10.123
inches can be reported as either 10123 or 10.123.
Each report to terminate with a <CR><LF> or just a <CR>.

F.1.1 Overview
Summagrid IV report formats conform to MM/SummaSketch standards. To
accommodate the emulation needs, choose either a binary or an ASCII BCD format.
The reports are in counts of resolution.
NOTE: When configuring the Summagrid IV for the default 500 lpi resolution in
binary format, the active area size will be limited to 32.766 inches. If you wish to
utilize the entire active area, you must set the fixed resolution to 200 lpi.
