External synchronization
The Processing Unit is has a connection for interface to an external synchronization
system.
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.
This connection is for interface to an external synchronization system, for example
K-Sync. An external synchronization system is used when multiple echo sounders are
employed on the same vessel.
The external synchronization connector is located on the CBMF board in the processing
unit. If the Processing Unit has two CBMF boards the lower one must be used for
synchronization.
This is an optically isolated connection that requires ~10mA current. Input power and
resistor value must be adjusted accordingly. The connector is RJ45 type.
RJ45 connector pin layout
Pin 3 and 6 is used by Kongsberg Maritime only.
