Caution
Unused connector sockets should be sealed against water ingress using the
provided blanking cap.
Caution
When mating the connectors ensure that both plug and socket are completely
dry.
The Micron Echosounder head is protected against voltage surges on the power and
communication lines using internal supressers. Sustained over voltage will damage the unit.
Power can be applied from a rectified transformer PSU and the output of the PSU must have
a filter capacitor of not less than 470μF, for each head being powered. If an unregulated PSU
is used, then make sure that the voltage value measured at the head is in the range specified
in Chapter 1,
, in power on/off and running conditions.
Note
To reduce the risk of damage due to over-voltage it is recommended that 100mA
fuses are used in the communication lines and appropriate fuse is used in the
power supply (e.g., 1A at 12V or 500mA at 24V).
Note
The Aux port provides pass through voltage from the Main port.
If using, or testing, with a SeaHub it is possible to power the Micron Echosounder from the
SeaHub using a combined power and data cable (port C or D). Please refer to the SeaHub
manual for details of the port pin-out diagram or contact
Tritech International Ltd
who can
provide a ready made cable.
If using an RS232 connection from a computer, or if the Echosounder is mounted to an ROV
it will be necessary to construct a cable with an appropriate Micron connector on one end and
power/data on the other end. Contact
Tritech International Ltd
for an appropriate cable whip.
