6.1 Command Syntax
The 8743-CL Controller/Driver utilizes an ASCII command set and also outputs system
status in ASCII format. Commands may be either upper or lower case characters.
The diagram below illustrates the 8743-CL controller command syntax. As indicated in
this diagram, a valid command consists of three main fields. The first field consists of a
numerical parameter “xx”, the second field consists of a two letter ASCII mnemonic, and
the third field consists of numerical parameter “nn”. The command is finally terminated
by a carriage return. For example, 3PA10 is a valid command.
If a command does not require parameter “xx” and/or parameter “nn”, that field may be
skipped by leaving a blank character (space). For example, 1DH, and VE? are valid
commands.
Multiple commands can be issued on a single command line by separating the commands
with a semi-colon (;). For example, “3VA1500; 3PA1000” is a valid command line. If a
command line has multiple query commands, the response string from the controller will
have responses to all the query commands in the command line. Each response in the
response string will be separated by a semi-colon. For example, the response to “3VA?;
3AC?” command can be “2000; 30000”. In this example, the value 2000 is a response to
3VA? command, and the value 30000 is a response to 3AC? command.
