Simrad ES60

• 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.

–Thetwo

TrigOut signals are open collector outputs (max

100 mA) containing a 100 kohm pull-up resistor to +5 Vdc.

–

TrigOut+ is normally low, and TrigOut- is the logical

inverse of

TrigOut+.

– In internal trigger mode the sounder starts transmitting as

soon as it is ready for the next ping.

TrigOut+ 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 ﬁnished 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

TrigIn+ input or a high-to-low transition at the TrigIn-

input. TrigOut+ goes high when the transceiver is ready to

transmit, and it goes low again when all frequency channels

within the transceiver have ﬁnished 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) l evel is provided when the alarm is

enable.

– Note that this output m

ust not be used to power lamps,

speakers or sounder directly. The alarm signal m

ust be

connected to an opto-coupler, a relay or a similar device to

power peripheral alarm units.
