Setting Custom Properties (CalComp)
Plot Color Merge Control
Specifies the connection type.
CalComp stores plot data as records. Each record starts with one or two specific characters called SYNC codes, and each record ends with one specific character called an EOB/EOM code. You can use a checksum character to validate the plot record. You must set up the plotter to expect SYNC codes, EOB/EOB codes, and checksumming in the plot data. If the plotter setup does not match the driver, the plotter ignores the plot. If you use the CalComp Device Control Language commands, this driver will set up the plotter automatically.
Connection Fields
| Dialog Box Field | Description |
|---|---|
| Number of SYNC Codes | Sets the number of SYNC codes. |
| SYNC Code | Precedes each CalComp plot record. This code can have a value ranging from 2 through 127, inclusive. These codes directly relate to an ASCII character. If you are not using CDCL, the plotter SYNC code settings must match the driver SYNC codes. |
| EOB/EOM Code | Indicates the end of a CalComp plot record. The End of Buffer (EOB) or End of Message (EOM) codes directly relate to an ASCII character and can have a value ranging from 2 through 31 inclusive. |
| Timeout | Defines an amount of time the plotter waits for data. If the plot data sent to a plotter stops, the plotter will wait for the timeout period set here. After that time is reached, it terminates the plot and force plots the data it received. |
| Enable Checksumming | Adds a checksum character in front of the EOB/EOM code to verify a plot record. The plotter driver calculates the character and the plotter uses it to validate the plot record. Using serial XON-XOFF protocol or Centronics parallel protocol, the plotter can detect a checksum error but cannot recover from it. In these two physical connection modes, checksumming has no value. |
| Add Pad Characters | Adds padding characters to the plot record in the event the plotter encounters a buffer overflow error. |
