Campbell logger configuration¶
Campbell logger configuration for AURORA. The Campbell logging devices are logging the data from all of the AURORA instrumentation with the exception of the large AC instruments (radar, hatpro and ceilometer) and the WxCam. Even though some of these devices are capable of logging data independently (the Vaisala met station, and the licor for example), we're integrating all of these data into common files using the Campbell logger, this helps us keep data together and sync timings ect.
The logger is configured using the Windows software LoggerNet on the Windows VM. The software needs installing with a key from Campbell that means it can only be running on a single computer at once (although it possible to change the computer). Neely has a USB with a spare copy of the software. The key for this version of the software is LGRNET-8595-JWACQQUDNVNCYAKL
LoggerNet runs a program that goes around and collects all data from the logger as instructed and integrates it into a .dat file ..... add details here about how this file is saved, updated, backed up, and synched to linux......
We are running xxxx loggernet programs; AURORA-ASFS-COMPLETE.CR1X and EC-NEW.CR1X??? ..... add details here about the different programs, one is handling 20Hz sonic and licor data for fluxes, the other is logging all remaining variables with xx s sampling interval....
Logger model: CR1000Xe-XT-CC (-55 to +85 C, with campbell calibration) Serial number: 74035
Campbell peripheries: SDM-SIO4A ; 4 port Serial extension unit, SN: E5215 SDM-CD16S ; 16 port solid state DC controller, SN: 2000 Kingston 16 gb micro SD card (must be 16Gb)
Input power is 12VDC. The unit is protected by a 10A breaker.
There's various initial configuration options that are set up using the LoggerNet software on the windows VM. ... Michael to fill in the details here... But I think these config settings are backed up in the file AURORA-ASFS-COMPLETE.tdf
"Logic" switches¶
The SDM-CD16S has 16 DC voltage outputs that can be switched on and off manually or under datalogger control. Seperate inputs for the power to the outputs (48VDC max) and the power to the logic (7-48 VDC) allow the option of powering the logic from the datalogger 12 V while switching to a higher voltage. LEDs allow a visual indicator of active outputs.
The maximum current per channel is 2A, with a 10A max for the whole unit. SDM communication is wired into the Datalogger SDM control ports: C1 (data), C2 (clock), C3 (enable) - wired to C1, C2, and C3 on the logger for simlicity.
The main toggle switch has three positions: MANUAL, OFF, and AUTO. In MANUAL the outputs are controlled by the position of the rocker switches. in AUTO, the state of the relays is controlled by SDM commands from the datalogger. On AURORA installation, this should be set to AUTO. All of the rocker switches are in the 'on' position to keep things simple and memorable.
There's a rotation switch that controls the addresses of the 16 channels for the campbell logger. Currently set in position zero, this means the base 10 address for the cambpell logger of the 16 ports is 0 to 15.
...........add details of how we control the logic switches by modifying a txt file on the linux vm that is read on every scan by the campbell logger program.....

SDM-SIO4A Wiring¶
The SDM-SIO4A is a four port extension for Serial Input/Output devices managed by the Campbell Logger. It's wired into the logger in the same way as the other SDM module: C1 (data), C2 (clock), C3 (enable) - wired to C1, C2, and C3 on the logger for simlicity. COMM ports 32 to 47 reserved for SDM-SIO4A. It has an address switch on the side that sets the address of the first serial port (port 1), the rest of the ports have sequential addresses. Position 0 on this switch corresponds to port 1 = comm port 32. Since we're talkin got the KT15 on port 37, we must have the addres switch set to position 4 (check).
