Output Format Setup
Commands
(continued)
#iiLegacy=x
x=0
: Allow all commands documented in
this manual.
Default
.
x=1
: Set units to °C and dbar, and enable
output of temperature and pressure
(disable sample number). Do not allow
user to change those settings. Modify
#iiDS
response to more closely match
firmware < 4.0, for consistency with older
instruments.
Autonomous Sampling (Logging)
Commands
Autonomous sampling commands direct the 39
plus
-IM to sample data at pre-
programmed intervals and store the data in its FLASH memory.
#iiSampleInterval=x
x=
interval (5 – 21600 sec) between
samples. When commanded to start
sampling (with
#iiStartNow
,
#iiResumeLogging
,
#iiStartInterval
,
#iiStartLater
,
#iiGetAvgRestart
, or
#iiGetLastRestart
or
GData
),
39
plus
-IM takes a sample, stores data in
FLASH memory, and powers down every
#iiSampleInterval
seconds.
#iiStartNow
Start logging now, at rate defined by
#iiSampleInterval=
. Data is stored in
FLASH memory. If communicating via
USB when command is sent, will start
sampling after USB cable is removed.
#iiResumeLogging
Start logging. Logging starts
#iiSampleInterval
seconds after
command is received. Cannot be sent
when communicating via USB.
#iiStartInterval
Same as
#iiResumeLogging
. Cannot be
sent when communicating via USB.

Notes:
•
In SeatermIM, to save data to a file
(if transmitting occasional samples
while logging), click the Capture
menu before beginning logging.
•
If the 39
plus
-IM is logging data and
the battery pack voltage is less than
5 volts for ten consecutive scans,
the 39
plus
-IM halts logging and sets
the logging status to low battery.
•
If the FLASH memory is filled to
capacity, autonomous sampling
stops (39
plus
-IM does not overwrite
data in memory).
Note:
#iiLegacy=1
forces the 39
plus
-IM to
act like older 39-IMs (firmware < 4.0),
which did not have as many user
output selections; it is intended for use
by customers who have a mix of old
and new instruments. However, note
that the
#iiDS
response has some
small changes from the older 39-IM.
