30 30 35 

 

As can be seen above, positive input numbers use 
the ASCII “+” whilst the output will use a “sp” 
space character to represent a positive number. 
Negative numbers are identical for both input and 
output.  
 

Combining 
Commands 

Commands and queries can be combined to form a 
large continuous command. 
Each command must be separated with a line feed 
character< ^END>(or <^J>). The combined 
command must be terminated with a line feed and 
carriage return character< ^END^M>(or <^J^M>). 
All messages and parameters will be returned 
sequentially with a line feed character (< ^END>(or 
<^J>

)separator.
