Programming RS-232C Remote Commands

There are two types of remote commands for the GB1400:

∙Set commands (commands)

∙Queries commands (queries

The set commands force the GB1400 to take a specific action. The query commands direct the GB1400 to return status information.

Commands are entered one line at a time. Errors may be corrected while entering a line, with the backspace key. A command string is terminated by a carriage return, which transmits the string to the GB1400 and executes the command string. All valid commands are executed. Incorrect or unsupported commands are responded to by an error message. RS-232C error messages follow after this section.

These command lines can contain either a single command or multiple commands. The command line may contain both queries and commands. Each individual command within the command line must be separated by semi-colons (;), parameters must be separated by comma (,). Non-decimal numeric parameters, Hexadecimal, Octal, and Binary must be preceded by a ‘#H’, ‘#Q’, or ‘#B’, respectively. The entire command name does not have to be completely entered for the command to be recognized as valid. There is a minimum valid length associated with each command, which is the length that makes it unique from all other commands.
