timing information. If both the ZDA and UTC are input, the UTC will take priority; the SIM will
automatically ignore ZDA while receiving UTC. The UTC status code (‘ab’) is ignored.
Setting up the time synchronisation is done through the Sonic Control software detailed in Chapter
6.
In that each of the SIM serial ports provides 12VDC on selected pins, it is not recommended to use a
fully wired serial interface cable as this may cause some GPS receivers to stop sending data. Use a
cable with only pins 2, 3 and 5 wired, if possible.
5.1.5
Motion Input
The roll component, of the motion data, is used for roll stabilisation. Currently, the only acceptable
format is the standard TSS1 data string. It is recommended to set the motion sensor to output the
highest baud rate and highest update rate possible, preferably 100 Hz or higher.
Connect the motion data to the DB-9 labelled Motion, on the SIM. Setting up the serial port
parameters is done through Sonic Control, which is covered in Chapter 6.

SVP input
5.1.6.1
Connecting the sound velocity probe
The sound velocity probe is used to provide the sound velocity at the sonar head, which is used for
the receive beam steering. It is not used for refraction correction; that must be accomplished in the
data collection software employing a full water depth sound velocity cast.
5.1.6.2
Valeport miniSVS
The miniSVS comes with a 15 metre cable. The cable carries both the DC power (8 – 29V DC) to the
probe and the data from the probe to the SIM. The miniSVS is set for a baud rate of 9600 and will
start outputting sound velocity (Format: <sp> xxxx.xxx m/sec) as soon as power is applied. 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.
Setting up the SVP input is done through the Sonic Control software detailed in Chapter 6.
