• Transmit synchronisation (pins 12, 13, 23, 24 and 25)
–
TrigIn
and
TrigOut
are digital signals provided for transmit
synchronisation with external equipment of various makes.
– The two
TrigOut
signals are open collector outputs (max
100 mA) containing a 100 kohm pull-up resistor to +5 Vdc.
– is normally low, and
TrigOut-
is the logical
inverse of .
– In internal trigger mode the sounder starts transmitting as
soon as it is ready for the next ping. goes high
(output transistor is not conducting) when the transmit
pulse starts, and it goes low again when all frequency
channels within the transceiver have fi nished transmitting.
The
TrigIn
signals are totally disregarded.
– In external trigger mode the behaviour of these signals is
slightly different. Transmission is delayed until a pulse is
detected at one of the
TrigIn
inputs; a low-to-high transition
at the input or a high-to-low transition at the
TrigIn-
input. goes high when the transceiver is ready to
transmit, and it goes low again when all frequency channels
within the transceiver have fi nished transmitting.
– The
RemoteIn
signal at pin 23 switches the transceiver
on/off. Left open 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
• Alarm out
– A positive (+ 5Vdc) level is provided when the alarm is
enable.
– 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.
