SBE 37-SMP-ODO (RS-485) MicroCAT Reference Sheet
(see SBE 37-SMP-ODO [RS-485] MicroCAT User’s Manual for complete details)
Setup
1.
Install
AA lithium cells
(Note:
ODO MicroCATs use a battery pack with a yellow cover plate
)
:
A.
Remove connector end cap
: Wipe dry housing/end cap seam. Remove 2 cap screws from end cap, and twist end cap
counterclockwise. Pull end cap out. Disconnect Molex connecting to battery pack. Wipe dry O-ring mating surfaces in housing
with lint-free cloth.
B.
Remove battery pack and install cells
: Loosen captured screw in battery pack cover. Use handle to lift pack out of housing.
Keep handle upright. Unscrew cover plate. Roll 2 O-rings on side of pack out of grooves. Insert cells, and roll 2 O-rings back
into grooves. Align pin on cover plate PCB with post hole, keep handle upright, and screw cover plate onto battery pack.
C.
Reinstall battery pack and connector end cap
: Align D-shaped opening and pins on shaft. Lower battery pack into housing;
push gently to mate. Tighten captured screw to secure battery pack in housing. Remove water from O-rings and mating surfaces
with lint-free cloth. Inspect O-rings and mating surfaces for dirt, nicks, and cuts. Clean as necessary. Apply light coat of O-ring
lubricant to O-ring and mating surfaces. Plug Molex connector together. Fit end cap into housing. Reinstall 2 cap screws.
2.
Install cable. Connect to computer serial port.
3.
Double click on SeatermV2.exe. SeatermV2 opens; in Instruments menu, select
SBE 37 RS485
. Seaterm485 opens.
4.
In Seaterm485’s Communications menu, select
Configure
. In dialog box, select Comm port and baud rate (factory set to 9600). Set ID to
Automatically get ID
for 1 MicroCAT on line; set ID to
Use fixed ID
for multiple MicroCATs on line. Click OK.
5.
Seaterm485 should automatically connect to MicroCAT. As it connects, it sends
#iiGetHD
(ii=ID) and displays response, and then fills
Send Commands window with list of commands for your MicroCAT.
6.
Program MicroCAT for intended deployment (see other side of this sheet for command list):
A.
Ensure all data has been uploaded from memory, and then send
#iiInitLogging
to make entire memory available for recording.
B.
Set Date and Time (
DateTime=
or
#iiDateTime=
).
C.
Set up other parameters if desired. User-selectable sampling modes include:
•
Autonomous
– At pre-programmed intervals, wake up, run pump, sample, store data in memory, and go to sleep.
•
Polled
– On command, run pump, take 1 sample, and send data to computer.
D.
Use one of following sequences to start logging:
•
#iiStartNow
to start logging now, taking a sample every
#iiSampleInterval=
seconds.
•
#iiStartDateTime=
and
#iiStartLater
to start logging at specified date and time, taking a sample every
#iiSampleInterval=
seconds.
Deployment
1.
Wiring – deploy with dummy plug or cable (for external power and/or serial communication during deployment).
Install locking sleeve.
2.
Mount MicroCAT, using Sea-Bird or customer-supplied hardware.
MicroCAT is intended for deployment with connector at bottom
for proper operation – see manual for details.
Data Upload
1.
Connect cable from MicroCAT to computer.
2.
Double click on SeatermV2.exe. SeatermV2 opens; in Instruments menu, select
SBE 37 RS485
. Seaterm485 opens.
3.
In Seaterm485’s Communications menu, select
Configure
. In dialog box, select Comm port and baud rate (factory set to 9600). Set ID to
Automatically get ID
for 1 MicroCAT on line; set ID to
Use fixed ID
for multiple MicroCATs on line. Click OK.
4.
Seaterm485 should automatically connect to MicroCAT. As it connects, it sends
#iiGetHD
and displays response, and then fills Send
Commands window with list of commands for your MicroCAT.
5.
If sampling autonomously (logging), command MicroCAT to stop logging by sending
#iiStop
.
6.
Click Upload menu to upload stored data. Seaterm485 prompts you for upload file name and other upload options.
7.
When upload completed, Seaterm485 prompts you to run SBE Data Processing to convert uploaded .hex file to .cnv file for use by other
modules in data processing software. Process file and review data to ensure all data has been uploaded.
Command Instructions
•
Input commands in upper or lower case letters, and register commands by pressing Enter key.
•
MicroCAT sends error message if invalid command is entered.
•
If new command is not received within 2 minutes after completion of a command, MicroCAT returns to quiescent (sleep) state.
•
If in quiescent (sleep) state, re-establish communications by selecting
Connect
in Seaterm485’s Communications menu,
sending two @ characters, or pressing any key.
•
For reliable operation, all commands
may
need to be preceded with two
@
characters.
Example
(status command for MicroCAT 01):
