Recessions for straps
When mounting the Vectrino, use
the recessions to strap it to the
structure. Never use the probe
stem as mounting point.
Communication Between Vectrino and PC
The Vectrino computer interface is of the RS 232 type. However, if you are going
to use more than one Vectrino at the time, you will easily run out of serial ports
on your PC. What to do then?
Enter USB interface. By using a USB hub accepting serial interfaces at one end
and USB at the other, you may connect a multitude of Vectrinos to your PC. The
USB interface will appear transparent; both the Vectrino and the PC will regard
the connections as standard RS 232, so baud rate will retain its meaning even in
the case of USB connections.
USB cables should not be too long, a common recommendation sets the up-
per limit to approximately 5 m, so in practical cases the major part of the cable
length used will be of the RS 232 type.
Using Long Cables
Default RS 232 baud rate setting is 19 200 baud for the Vectrino and 57 600 for
the Vectrino .
Keep in mind that changing environmental conditions could cause RS 232 com-
munications to fail over a long cable without apparent reason. If you experience
