7.
Display 39
plus
-IM status information by typing
#iiDS
(ii=39
plus
-IM ID)
and pressing the Enter key. The display looks like this:
SBE39plus-IM v4.4.0 SERIAL NO. 03907844 23 Mar
2016 08:43:31
battery voltage = 7.16, back-up voltage = 3.34
not logging: initialized
sample interval = 30 seconds
samplenumber = 0, free = 5592405
configuration = temperature and pressure
data format = converted engineering
output temperature, Celsius
output pressure, Decibar
output sample number
temperature = 23.16 deg C
8.
Command the 39
plus
-IM to take a sample by typing
#iiTS
(ii = 39
plus
-IM
ID) and pressing the Enter key. The display looks like this (if 39
plus
-IM
includes pressure sensor,
#iiOutputFormat=1
, and
#iiFormat=0
):
07844, 23.1801, 0.106, 23 Mar 2016, 08:46:19
where
07844 = 39
plus
-IM serial number
23.1801 = temperature (units defined by
#iiSetTempUnits=
)
0.106 = pressure (units defined by
#iiSetPressUnits=
)
23 Mar 2016 = date
08:46:19 = time
These numbers should be reasonable; i.e., room temperature, pressure
(gauge pressure), current date and time (shipped from the factory set to
Pacific Daylight or Standard Time).

Each IM instrument on a mooring must have a unique ID for
communicating with the SIM and computer. Set the ID as described
below,
first verifying that only one 39plus-IM is on-line before you set
the ID
:
A.
Set the 39
plus
-IM ID by typing
*ID=ii
(ii= user-assigned ID number)
and pressing the Enter key.
B.
The computer responds by requesting verification, requiring you to
again type
*ID=ii
and press the Enter key.
C.
Record the ID for future reference.
D.
In the Communications menu, select
Configure
. Set to
Use fixed ID
,
enter the new ID, and click OK. This provides SeatermIM with the
correct ID information for sending commands listed in the Send
Commands window.
10.
Send additional commands, as desired.
11.
Command the 39
plus
-IM to go to sleep (quiescent state) by typing
PwrOff
and pressing the Enter key.
The 39
plus
-IM is ready for programming and deployment.
Important! When testing and ID setting is complete for all the IM
instruments, reinstall the J5 jumper on the SIM PCB.
The jumper must be
installed for Normal Deployed operation.
Note:
The SIM and 39
plus
-IM have timeout
algorithms designed to:
•
restore control to the computer if an
illegal command is sent
•
conserve battery pack energy if too
much time elapses between
commands
If the system does not appear to
respond, send
PwrOn
. See
Timeout
Descriptions
in
Section 4: Deploying
and Operating 39plus-IM
.
Note:
If more than one IM instrument is
on-line when you set the ID, all IM
instruments will be set to the same
ID.
The inductive modem receivers in
IM instruments are very sensitive; two
IM instruments that are side-by-side
will take the same ID, even if one of
them is not on the IM loop.
Therefore,
separate IM instruments by at least
2 meters when setting IDs.
