Signal naming conventions
Manufacturers use several names to denote the various signals. The first column in the
table below shows the signal name that has been adopted for the K-Sync application.
The second column shows the typical names used for the corresponding signal of the
sonar. These are names used by the Kongsberg echo sounders
Table 1 Signal naming convention
K-sync signal Connects to Direction Description
Ready to
transmit (RTT)
Sync out or
Ready to
Send (RTS) To K-sync
Signal is active when sonar is ready
to transmit; inactive while the echo
sounder is transmitting, receiving or
processing samples. Signal may also
go inactive whenever pinging for the
particular echo sounder is turned off,
which will be properly interpreted
by K-Sync.
Transmitting Trig out
To K-sync
Signal is active (by default) for the
duration of the transmit pulse.
Trigger Sync in or
CTS From K-sync Signal causes sonar to ping.
RTT - Ready to transmit
RTS - Ready to send
CTS - Clear to send
K-Sync Signal Interface
K-Sync controls pinging and receives status from the echo sounders via the signal
interface and provides one output and two inputs for each echo sounder:
•
Trigger
output: tells the echo sounder when to transmit/ping
•
Ready to transmit
(RTT) input: communicates when the echo sounder is ready for
next trigger
•
Transmitting
input: tells the Synchronizing Unit when the echo sounder has started
and is in the process of transmitting
Feedback signals from the echo sounder
Feedback signals are not required but will be used when available. If feedback signals
are not available, the Synchronizing Unit can estimate the waiting period required for the
echo sounder to become ready.
