Reference
Sampling Modes
• Polled – On command, wake up, run pump, take one sample, transmit data, and go to sleep.
• Autonomous – At pre-programmed intervals, wake up, run pump, sample, store data in FLASH memory, and go to sleep.
• Combo – On command, transmit last Autonomous sampling data.
Averaging – On command, calculate and transmit average of Autonomous sampling data since last request.

Setup
Install AA lithium cells (Note: ODO MicroCATs use a battery pack with a yellow cover plate):
1.
A. Remove modem 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 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 battery pack out of housing. Keep
handle upright. Unscrew yellow cover plate from top of battery pack assembly. Roll 2 O-rings on side of battery pack out of grooves. Insert
cells into battery pack, and roll 2 O-rings into grooves on side of battery pack. Align pin on battery cover plate PCB with post hole, keep
handle upright, and screw yellow cover plate onto battery pack assembly.
C. Reinstall battery pack and modem 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. Double click on SeatermV2.exe. In Instruments menu, select SBE 37 IM. SeatermIM opens.
3. In Communications menu, select Configure. In dialog box. Input Comm port and baud rate. 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. SeatermIM automatically connects 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. Ensure all data has been uploaded from memory, and then send #iiInitLogging to make entire memory available for recording.
If #iiInitLogging is not sent, data will be stored after last recorded sample.
6. Set Date and Time (#iiDateTime=).
7. Set up other parameters as desired — see Command Instructions and Command List.
Deployment
1. Attach MicroCAT to insulated
mooring cable with Sea-Bird
mounting brackets. MicroCAT is
intended for deployment with the
sensors at the top for proper
operation – see manual for details.
Install (optional) ICC on mooring
cable.
2.
See MicroCAT manual for SIM
wiring and configuration; see IMM
manual for IMM wiring and
configuration.
Data Upload
1. Connect cable from MicroCAT to computer.
2. Double click on SeatermV2.exe. SeatermV2 opens; in Instruments menu, select SBE 37 IM. SeatermIM opens.
3. In 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. SeatermIM automatically connects 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.
7. SeatermIM 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 an 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 SeatermIM's Communications menu.
