Communication Protocol 

 

Types of Serial Communication 

 

Three types of serial communication can be transmitted between the host and DN-700CB: 

 
 
1.

 

Control commands sent to DN-700CB from the 
host 

You can use control commands to make DN-
700CB perform a desired function (such as playing 
or skipping a track). 

When DN-700CB receives a control command 
from the host, DN-700CB executes the command. 

 

 
 
 
 
2.

 

Status request commands sent to DN-700CB 
from the host  

You can use a status request command to 
determine the current state of one of DN-700CB’s 
components (such as whether there is a disc in the 
CD slot, how many tracks are in the current 
tracklist, etc.).  

When DN-700CB receives a status request 
command from the host, DN-700CB answers the 
host with the requested status information. 

 

 

 
 
3.

 

Status information automatically sent to the 
host when a change is made from DN-700CB 

When a change to DN-700CB is made from the 
device itself, DN-700CB automatically sends 
status information to the host.
