Simrad ES70
• Supply voltages (output)
– Pin 5: +12 Vdc, max 100 mA (Ground on pin 18)
– Pin 6: -12 Vdc, max 100 mA (Ground on pin 19)
– Pin 7: +5 Vdc, max 200 mA (Ground on pin 20)
• Transmit synchronisation (pins 12, 13, 23, 24 and 25)

– In external trigger mode, transmission is delayed until a pulse is detected at one
of the inputs; a low-to-high transition at the

have finished transmitting.
– The

transceiver is on. If grounded (less than +2.5 Vdc) the transceiver is off.
• Event in
Use a simple non-locking push-to-make switch to trigger an event. A vertical line is
drawn on the echogram
Note
This input is not supported by the ES70 Fish finding echo sounder.
• Alarm out
A positive (+ 5Vdc) level is provided when the alarm is enable.
Note
Note that this output must not be used to power lamps, speakers or sounder directly.
The alarm signal must be connected to an opto-coupler, a relay or a similar device to
power peripheral alarm units.
Note
This output is not supported by the ES70 Fish finding echo sounder.
