Respironics V200 Ventilator Operator’s Manual

REF 1057983 A

Commands are transmitted as a series of four ASCII characters followed by a 
carriage return. Valid commands will be stored and response transmissions will 
be sent in the order the corresponding commands were received. 

Unless stated otherwise, all fields will be left justified and six (6) characters in 
length. A comma will separate each field, except for the field following the 
start code. Each data transmission shall be terminated with a carriage return.

In the following subparagraphs, a space is designated as “

◆”. When data is 

unavailable, the output field shall contain “

◆◆◆◆◆◆” 

When the ventilator receives SNDA followed by a carriage return, it will 
respond by transmitting the information shown in Table 13-4: “Ventilation 
Report”. The ventilator responds to the SNDA command by returning a string 
with a variable length. The second and third fields define the length of the 
message. The second field indicates the number of characters between the 
start and stop codes. The third field indicates the number of fields between 
the start and stop codes. The fourth field is the start code, 02H. The last field 
in the string is the stop code, 03H, indicating the end of the message. 

NOTE:

The SNDA command is only available in Normal mode.
