APPENDIX A
Programming the LD100
Command Line
The LD100 is programmed by means of a “Command Line”, which is an ASCII string of up to 255 characters that contains one or more individual instructions to the LD100. The Command Line offers the best compromise between manual opera- tion via a data terminal and automatic control via a controller.
Command Line Entry
Variable Adjustment Commands:
B or b Adjust Brightness Level
This command is follow by an integer between 0(minimum) and 255(maximum). Example B1 or B12 or B123, ect.
C or c Adjust Contrast Level
This command is follow by an integer between 0(minimum) and 255(maximum). Example C1 or C12 or C123, ect.
A Command Line can be entered in either upper or lower case by means of a data terminal or other controller. The Echo Mode determines the response of the LD100 to the incoming data stream. If the Echo Mode is ON (E1 command), the entered char- acters are echoed back to the host, and any mes- sage are sent in its entirety. IF Echo Mode is OFF (E0 command), no characters are sent to host.
Command Syntax
Commands consist of a header followed by a key- word followed by additional parameters if needed. The header is used to identify the product, in the case the header is: LD100, . Keywords are single characters followed by integers (if needed). All com- mands must be separated by a comma ‘,’. White spaces are ignored and may be used. All com- mands strings are terminated by a CARRIAGE RETURN (0x0d). Commands may in entered in any order as the user see fit.
