Power and Communication Cable
The power and communication cable is connected to the end bell con-
nector. The cable supplies external DC power (15–48 V) and provides two-
way serial communication with an external computer. It also provides four
analog outputs (0-5 V DC) for input to an AD converter.
The cable also provides synchronization options when the Vectrino is used
as master or slave to synchronize measurements with other Vectrinos
and/or other instruments.
Cable Wiring. By default, the Vectrino is shipped with a 12-pin connector
and cable. The connector type is either a splash-proof connector or an
MCBH-12-FS waterproof connector. The Vectrino power lines are diode
protected, hence, you do not have to worry about wiring the Vectrino
power backwards. If you do, it will not damage your instrument. The pin-
out is shown in the side bar.
