Change breath data update rate
Allows the host to specify how often the Module sends a breath
data packet.
where xx (ASCII) is converted to a 8 bit binary number (yyzz
zzzz) with yy defining how often the breath data is
updated.
If yy = 00 binary, Breath data packet update rate is defined by
zzzzzz, where zzzzzz is in tenths of seconds. The 6
lower bits = (seconds
× 10). Odd values are rounded up
to even values.
If yy = 01 binary, Breath data packet update rate is every breath
where zzzzzz = doesn’t matter.
Exception: If the “no breath” condition occurs, data is sent
at 1 second increments.
If yy = 10 binary, Breath data update rate is when the data changes,
where zzzzzz = doesn’t matter.
Exception: If after 15 seconds the breath data has not
changed, data is sent after the next breath. This does not
guarantee a 15 second update; however, if the “no breath”
condition has occurred, the “no breath” timeout takes pre-
cedence.
Exception: If the “no breath” condition occurs, data is sent
at 1 second increments.
If yy = 11 binary, Not defined.
Examples:
send a breath data packet at .6 s interval (Odd values
rounded up)
send a breath data packet every breath
send a breath data packet every time the data changes
Special case:
no breath data sent (Note: Continuous CO
2
mode would
use this command.)
