Simrad EK60

850-164696 / A
GPT Cabinet
The cables shown and specified here are those used when the
EK60 is implemented with a GPT Cabinet for IP55 protection.
The cabinet may contain one or two General Purpose
Transceiver (GPT) units and an ethernet switch. All internal
cabling in the cabinet is made by the manufacturer.
Note that all cables connect to the main tagblock with the
exception of the ethernet cable(s) and the transducer cables(s).
C10 - Ethernet
If only one General Purpose Transceiver (GPT) is mounted in
the GPT Cabinet, the ethernet switch may not be fitted. If a
single ethernet cable is used between the operating station and
the GPT unit, this must be twisted (”cross-over” connection). If
an ethernet switch is installed, straight cables are used. With two
GPT units in use, the switch is always present.
Note Screened ethernet (CAT5 STP) must be used.

C20 - Remote
This is the remote power control cable from the on/off switch.
The two wires are connected between digital ground and
position 19 on the tagblock.
→ Cable details on page 70.
C21 - New line
This is an input to provide manual count of survey lines. This
functionality is however not currently supported by the EK60
software.
C22 - Event
This is an input to provide a manual vertical line annotation on
the echogram. This functionality is however not currently
supported by the EK60 software.
C23A / C23B - Synchronization
There are two synchronization inputs, one to each of the
transceivers.
→ Cable details on page 70.
C24 - Motion sensor
Use this input for an analogue motion sensor. It is only
necessary to connect this input to one of the transceivers.
