Model DP569 User’s Manual 

Front-Panel Menus 

4-9 

Bypass Mode 
Is used to route the output of a secondary (standby) encoder to the switched audio 
output of the primary encoder. See Section 3.1.5. 

This menu gives you access to submenus controlling communication with other 
devices, and for upgrading software. 

The submenus are: 

•  Remote Baud Rate 
•  Unit Address 
•  Unit Name 
•  Test Tone 
•  Firmware Upgrade 

Remote Baud Rate 
Sets the baud rate for remote port communications. 

Unit Address 
The unit address is four characters long. The first character is limited to the numbers 
8–F, and the other characters are restricted to 0–F. The last character must be even. 

Unit Name 
Assign any text name you wish to your DP569; this is displayed on the top line of the 
main status menu. 

Test Tone  
Activates an internally generated test signal as the input to the encoding process rather 
than the currently selected input signal. In order to get a valid Dolby Digital output, 
encoding must also be active, which requires that the selected clock source be valid.  

Firmware Upgrade 
Enter the firmware upgrade menu when you have an upgrade to install. Download 
status information is displayed while in progress and when completed. See the 
documentation that accompanies the upgrade kit.
