Serial Command Syntax
Serial commands to the Vision 65/75 take the following form:
• Commands are in ASCII format.
• Commands must be in UPPERCASE; for example, X001X, not x001x.
• When you send a valid command, the Vision 65/75 executes it and echoes the command
back to the PC or control system. For example, when you send the command X001X, the
Vision 65/75 responds with X0_001X<CR>.
• When you enter an invalid command, the Vision 65/75 simply ignores it.
6Serial Communications
