Storing Custom Configurations
The application comes pre-configured with a few useful paths that can be found in the Paths
menu.
To add new paths, simply set up the desired configuration and select ‘Add Path’ from the Paths
menu, a window will appear asking for a name for this configuration. Fill in a descriptive name
(max 32 characters) and click OK to store this path. The paths are permanently stored on the
computer. A maximum of 32 paths can be stored.
To remove a stored path, select the path from the Path menu and click ‘Remove Path’ in the Path
menu. The Path will be permanently removed.
Analog Play and Record
The ES521 Demo System allows full playback and record capabilities from the main application
window. The 5216 supports two types of addressing:
Use current address – Recording or Playback starts from the position of the current address
pointer, no address is sent as part of the command. The address pointer can be retrieved from by
pressing the ‘Read Status’ button which displays the address bytes as two hexadecimal numbers
(high and low address byte)
Supply address – Record and Playback can be setup by sending an address with the Play or
Record command. See the 5216 datasheet for addressing details.

Play from address – Play from the address given in the box below the button.
Record – Record from the current address.
Record from address – Record from the address given in the box below the button.
