Using the command/response tables
The command/response tables on the next page list valid command ASCII codes, the scaler’s responses to the host, and a description of the command’s function or the results of executing the command. Upper and lower case characters may be used interchangeably in the command field.
The ASCII to HEX conversion table at left is for use with the command/response tables.
