2.3.2.1 Mother board
2.3.2.1.1 Power supply and internal battery option
The power supply input is 11 to 30 Volts DC (see specification in Appendix 2)
For operation from an AC source, an external adapter is required.
If the DC input is 15 Volts or more, the internal battery option may be fitted to allow operation
to continue in the event of power failure. The internal battery is automatically charged by the
power supply when external power is being supplied.
Power consumption and the period of operation from the internal battery option depend on the
mode of operation and are given in the specification.
The fuse values are both T1A.
2.3.2.1.2. Transducer connections
For an in-line configuration of velocity paths there will be 2 star junction boxes, 1 for each
transducer array. The coaxial cable from the upstream star box terminates at SK3. The
coaxial cable from the downstream star box terminates at SK6.
For a crossed configuration of velocity paths there will be 4 star junction boxes, 1 for each
transducer array. The coaxial cable from the upstream left star box terminates at SK3 and the
downstream right at SK6. The coaxial cable from the upstream right star box terminates at
SK4 and the downstream left at SK7.
If an upward facing depth transducer is being used, the coaxial cable from it terminates at
SK2.
