DVL Configuration Notes
The Rowe DVL does not work out of the box. It requires several parameters to be set. It is recommended that these parameters are set via pulse, the windows application from Rowe.
Mode DVL | ---
Sim 0 | ---
CEPO 3 | 3: 600 kHz 4 beam 20 degree piston
CERECORD 0,0 | 0,0: disable internal recording
CEAUTOSTART 3 | 5: disable autostart
C232OUT 0 | 0: disable 232 output
C422OUT 0 | 0: disable 422 output
CMACOUT 0 | ---
CUDPOUT 0 | ---
CBTON[0] 1 | 1: turn on bottom tracking
CBTTBP[0] 0.13 | 0.13s: create a pause between the Water Profile and Bottom Track ping
CBTFILT 0.000,0.000,10,1.000,0 | 0, 0: disable low pass filtering
CBTBL[0] 0.10,10.00 | 0.1, 10.0: ignore distance for the Bottom Track ping
CBTST[0] 0.900,10.000,10.000 | 0.9: Correlation threshold 10.0: Error Velocity threshold 10.0: Velocity threshold
CWTON[0] 0 | 0: disable water profiling
CWSSC 1,1,0,2 | 1,1,0,2: internal calculation of sound speed (only need salinity input)
CWT 15.00 | ---: use internal temperature sensor
CTD 0.00 | ---: use internal pressure sensor
CWSS 1500.00 | ---: use internal calibration
CHO 0.00,0.00,0.00 | ---
CHS 1 | ---
CTS 1 | ---
CVSF[0] 1.000,1.000 | ---: velocity scale factor (don't know)
C232B 9600,8,0,1 | ---
C485B 115200,8,0,1 | 115100,8,0,1: serial setting

C485G 0.05 | --- ???
CTRIG 0,-1807677180 | --- no trigger
COUTTRIG 0 | ---
CDVL |This sets the output format and function mode
CEI 00:00:00.20 | 5Hz: output rate
CWS 35.00 | Water Salinity (ppt)
CBTMX[0] 20.00 | 20.0: maximum depth to search for the bottom
CBTBB[0] 4, 4.000, 30.00, 4 | 4: Transmit Pulse Type and Processing 4.0: Lag length in vertical meters 30.0: Long Range Narrowband Auto Switch Depth 4: Beam Multiplex
CBTT[0] 20.0,150.0,20.0,8.0 | 20.0: SNR (dB) Shallow Detection Threshold 150.0: Depth(m) Shallow Switch 20.0: SNR(dB) Deep Detection Threshold 8.0: Depth(m) Deep Switch
Note that in order to change parameters you will need to stop the DVL pinging

Note that these configurations are subject to the VCS. Please ensure that when you log changes, they are actually what the DVL configuration is by using the Pulse command CSHOW.
We have two DVLs
- DVL 1 - configured for general use over a wide range of water depths link to config
- DVL 2 - configured for shallow water, 2 meters or less with standoff as low as 30cm link to config
