4.1.1. Software Switching to Maintenance Mode
Software Switching to Maintenance Mode can be utilized if Data/Maintenance Port (DP/MP) control line
is set to High Z (or 3.3v) level. To switch to Maintenance mode the special byte-sequences with special
meanings are used:
• Escape-Sequence: “+++” with 20 ms guard time before and after the command characters
• Escape-Acknowledge: “@00<CR><LF>” 20 ms toggling on CTS control line needed to
acknowledge switching from Data to Maintenance mode and vice versa. In Maintenance mode,
the unit’s serial port must keep CTS line always active.
