ESN100 Operation and Installation Manual
Chapter: Diagnostics
The values shown should be below 20mV once installed unless otherwise stated. High values can
usually be reduced by improved cabling and / or filters on the power supply.
Once installed, the mounting of the system can cause some changes from the default setup. This
can have an effect on the auto functions. To improve this the SNR calibration can be performed
and the system will optimise itself.
Each ping is plotted in the Scope screen
Transceiver unit JB50E1-SA Diagnostics
There are 5 LEDs on the PCB giving the status of the transceiver unit
LED1:Power ON
LED2:Communication transmit to display
LED3:Communication receive from display
LED4: Ping indication
LED5: FPGA OK
Here you can see the pings and the param-
eters in use to detect it, The green zone is
showing the detected depth , the red zones
are areas where the bottom detection will
not have an effect. This is typically at low
signal levels and in the ringing period after
the system sends a pulse.
