Cbmf Board Connectors - Kongsberg EM 712 Maintenance Manual

Switches and links
The CBMF board holds several switches and links.
These are implemented to allow the circuit board to
be used in several different configurations.
The switch setting on the CBMF board has to be
correct. All the switches on all the CBMF boards in
the Processing Unit should be set to OFF. OFF is when
they are pushed towards the edge of the circuit board.
Do not touch other switches or link settings.
The CBMF board is configured by Kongsberg Maritime for use in the EM 712. If you
receive a spare CBMF board, this is also set up correctly before it is shipped.

CBMF board connectors

The CBMF board holds a large connector for the backplane, as well as several front
mounted connectors.
This is a generic photo. The CBMF board used by the EM 712 may look slightly different
due to minor design changes on the protective lid and/or the front panel.
The CBMF board is fitted with the following connectors.
SYNC - signal used for synchronisation when multiple echo sounders are employed
A
on a vessel
1PPS - one pulse per second input signal used to synchronise the internal clock
B
in the Processing Unit
ETH1 - Ethernet connection to internal switch in the Processing Unit
C
ETH2 - not used for EM 712
