DSP420 RS232 

Information 

Data from DS 6ii03 

The RS232 interface for the DSP420 can be operated from any terminal that operates at 9600 baud 
with 1 start bit, 1 stop bit and no parity. Commands take the form of 2 ASCII characters, in some 
cases followed by a signed argument (‘nn’ below). All characters are echoed by the speaker. A 
carriage return character will execute the command and backspace is also implemented. When a 
command is executed, the speaker will return 8 characters. 

 

The following tables list the basic commands available and show examples of the messages 
returned. In each case the message retuned via RS232 corresponds with the display on the front 
panel of the processor.
