Version 3
Delay: The default setting is 0.00ms. This setting allows the operator to
specify how many milliseconds after the sonar ping the output pulse will be
sent.
Pulse Length: The default setting is 1.00ms. This setting allows the operator
to change the pulse length of the transmitted output signal. For the SeaBat
7125 ROV, the pulse length plus the delay must be slightly less than 20ms.
Apply: Click the Apply button to finalize changes.
4.2.5.3 1PPS Polarity
Rising edge: By default, the SeaBat system accepts positively polarized
(rising edge) 1PPS pulses to perform accurate time stamping.
Falling edge: If a negatively polarized (falling edge) 1PPS is used, the Falling
edge button in the Trigger/PPS Configuration dialog must be selected to
ensure accurate timing.
The 1PPS selection will appear on the sonar image control portion of the Primary
Display tab (see also
section 5.3.4 1PPS Input Indicator ).
