Ethernet Switch; Remote Control Unit (K-Rem) Description - Kongsberg EM 2040C Maintenance Manual

Ethernet switch

A high capacity Ethernet switch may be required.
If you use more than one Processing Unit, an Ethernet switch is required. This is used
to connect each Processing Unit to the Hydrographic Work Station. A high capacity
Ethernet switch (1000BASE-T) is included in the EM 2040C delivery.
Note
It is very important that a high quality Ethernet cable is used. You must use CAT-5E
quality or better. Using cables with lower bandwidth capacity will reduce the EM 2040C
performance.
1000BASE-T (also known as IEEE 802.3ab) is a standard for gigabit Ethernet over
copper wiring. Each 1000BASE-T network segment can be a maximum length
of 100 meters (330 feet), and must use Category 5 cable or better (including Cat
5e and Cat 6).

Remote Control Unit (K-Rem) description

A dedicated junction box has been designed to provide remote on/off switches with light
indication and interface to a remote synchronizing system. The junction box contains a
terminal block and four switches with lamps mounted in the front.
Note
The Remote Control Unit is not a standard part of
the EM 2040C delivery.
The Remote Control Unit is called K-Rem. It is
prepared for remote control and interface to an external synchronization system for
the following Kongsberg echo sounders:
• One Sub-bottom profiler (SBP 120 or SBP 300)
• Two EM multibeam echo sounders
• One EA single beam echo sounder
The Remote Control Unit is designed to be mounted in a 19 inch rack, but it is also
possible to mount it on a flat surface or in a bulkhead. It is also prepared for mounting
on telescopic rails.
