K-SYNC同步器使用说明

Network interface
Synchronizing unit
External depth for trigger period calculations may be input
Synchronizing unit
The Synchronizing unit provides one output and two inputs for each echo sounder: • Trigger signal (output): tells the echo sounder when to transmit.. • Ready to transmit signal (input): communicates when the echo sounder is ready for the next ping • Transmitting signal (input): tells the Synchronizing Unit when the echo sounder is transmitting.
Synchronizing unit
Software: • Network based SU operator SW may be run on any PC. • System setup • System monitoring When setup, SU will continue to trig the echo sounders if the operator SW is closed.

The Synchronizing Unit system consists of two main components: • A Workstation PC running the Synchronizing Unit (SU) application. • A Synchronizing Unit that interfaces with the echo sounders.

To add or remove echo sounders from this list:
For each echo sounder to be connected: • • • • Read their manuals and find info: Which output signals are available, Trig, CTS and On/OFF Signal level: TTL or RS232 Impedance
Synchronizing unit
CAUTION! Always power up the Synchronizing Unit before other echo sounders are turned on to avoid accidental pinging. Trigger outputs are undefined during power-up (first 20 seconds) and signal levels could potentially be interpreted as trigger pulse by the echo sounders until signal levels have settled.

Depth datagrams from echo sounder
Sync units‟s IP address and port number
Supported depth datagram formats: • NMEA depth (DBS, input datagram) • NMEA DPT (input datagram) • EAx: Single beam depth (EA 500 input datagram) • EM Depth „D‟: Multibeam depth (e.g. EM 120, EM 1002, EM 3000, EM 3002) • EM Depth „X‟: Multibeam depth (e.g. EM 122, EM 710) • EM Depth „E‟: Single beam depth (e.g. EA 600)

Yellow line separates the trigger groups
OS38 is busy much longer than EM 710 and determines the ping rate
Synchronizing unit
Operation: • • • SU controls pinging of each echo sounder. SU receives ready signals from echo sounders, but, if no status signals from echo sounders, SU may estimated ping time period.

How to assign echo sounders to trigger groups
If some echo sounders shall ping several times before next instrument, make many equal groups
Synchronizing unit
Settings->Installation->Installation settings
Mark the echo sounders that are actually connected to the SU. Add new echo sounder if it is not already in the list.

Avoid interference. Schedules the echo sounders transmit times.
16 trigger groups. Groups are triggered consecutively. Any number of echo sounders in a group (zero or more). Echo sounders in a group are triggered simultaneously. Optimizes timing: Transmit duration of each group is dependent on the measured active period for each echo sounder.
