DSP-62-AEC, DSP-62-UC – Protocol 3000 
LINK-MODE feature: 
 
Get linked signals 
groups info, this is a 
way to define group of 
signals for which any 
action made on one of 
them will be applied to 
all member of the 
group. 
The LINK mode of a 
group is defined using 
the command: X-
LINK-GROUP 
 
 This is an Extended 
Protocol 3000 
command.  
Used essentially by the 
web
