resume with the next number at the point of the stream’s termination. The

sequence numbers will not restart at one (1) if a scan list is temporarily stopped

and then restarted without reconfiguring the stream. A “limited” stream will

terminate once this sequence number equals the requested number of packets for

the stream. If a “limited” stream is restarted after expiring, it will restart at

sequence number 1.

For periodic hardware-triggered streams, that are never suspended and resumed

after being initially enabled, the sequence number may also serve as a “relative”

time stamp if the period (in milliseconds) of the hardware trigger is known.

If a special sub-command (ii=05) is used to select the content of a stream, other

binary status data may immediately follow the binary stream header and precede

the default Pressure EU Data (if selected). Other special acquired data groups

(per selected channel) may follow or replace the Pressure EU Data. Each datum

group in each packet will be ordered from highest channel number requested to

lowest channel number requested. Each datum (dddd) will be output per the

format code specified when the stream was configured (by sub-command “00” or

combination of “00” and “05”).

Example:

• Start all the streams configured in the previous example:

“c 01 0”

Read response:

“A”

Soon after the response is received, the requested data stream packets will begin

arriving in the host at a quantity, content, and rate determined by each stream’s

own particular current configuration (per both the “00” and “05” sub-commands).
