start outputting sound velocity (Format: <sp> xxxx.xxx m/sec) as soon as power is applied, and it is in
the water. The miniSVS cable is terminated with a female DB-9 RS-232 connector; this is attached to
the male DB-9 RS-232 connector, on the SIM, marked SVP. The probe is powered through the SIM’s
serial port 12VDC supply. The sound velocity can be input either via serial (with power provided) or
on the Ethernet (external power required).
Setting up the SVP input is done through the Sonic Control software detailed in Section 5.4.
4.1.6.3 Other supported sound velocity formats
The SIM can also accept sound velocity in the below-listed formats. Velocity (V) is parsed out of the
messages, and all other values are ignored.
SeaBird: "TTT.TTTT,CC.CCCCC,SSSS.SSSS, VVVV.VVV (CR/LF)" (39 chars)
SeaBird + P:"TTT.TTTT,CC.CCCCC,PPPPP.PPP,SSSS.SSSS, VVVV.VVV (CR/LF)" (49 chars)
SVP-C: "VVVVVDDDDDTTTBBCCCC (CR/LF)" (21 chars)
SmartSV: " VVVV.VV (CR/LF)" (11 chars)
The last format (“VVVV.VV) is also accepted with a flexible width.
There is no setup to accept these other formats, merely set the baud rate, and the SIM will automatically
parse the sound velocity.
