Command/response table for advanced instruction set commands
The advanced instruction set consist of four hexadecimal commands for uploading and downloading all or a portion of the switcher’s memory. These commands are for use by knowledgeable programmers, and result in a dump of data from (upload) or to (download) the switcher. Programmers can use the commands to exactly duplicate the settings among switchers with a minimum of effort.
