ES60/C20 - Alarm output
This output allows you to implement an alarm sounder or lamp
to indicate an echo sounder alarm condition. The output on the
General Purpose Transceiver only provides a positive (+5 Vdc)
level unable to power any external devices directly. If you wish
to use this function, you must therefore design an external device
containing an opto-coupler or relay to sense the alarm output.
This device can then trigger secondary devices such as sounders
or lamps. The cable, devices and mounting material must be
provided by the installation shipyard. If more than one General
Purpose Transceiver (GPT) is used, the alarm output on only
one of them is used.

ES60/C21 - Ethernet cable between Ethernet
switch and transceivers
When two or more General Purpose Transceivers are used,
these are connected to the computer by means of an Ethernet
switch. Cable
ES60/C14
is used between the switch and the
computer, this is a “straight” ethernet cable. For each transceiver,
one
ES60/C20
cable is used. Each of these are also “straight”
ethernet cables.
