Description
Meridian Menu Commands
The RS232 interface allows direct access to menu commands on version 3 Meridian 861. The existing
menu commands (ML, MR, MM, MP) have not been replaced but an extra command sequence allows
direct access to any menu and for a value to be entered into that menu. It must be noted that not all
menus will be available for direct access at all times. For example it is not possible to access the
Centre Delay wh ile listening in Direct mode. In these cases an error message will be returned.
The command string ‘APnnxx’ sets menu ‘nn’ to value ‘xx’, where both are hexadecimal numbers and
‘xx’ is two’s complement allowing negative values to be represented. The table below gives details.
When using this feature you should note that some menus work in half unit steps and that entering
invalid numbers will return an error message.
Example: AP0102 sets the treble to +1dB
AP0103 sets the treble to +1.5dB
