Command Mode: Command Mode allows raw commands to be sent to the HDR8X8/
HDR16X16 to control its various functions without the use of a menu or prompt. This
mode is intended for advanced use only.
There are two types of commands that you can issue the HDR8X8/HDR16X16:
Commands with CHECKSUM and Commands without CHECKSUM. The CHECKSUM is a
