Rear Panel Cable Connections

All dry-end cables provided by Teledyne Odom Hydrographic come with factory-installed connectors
to be attached at the appropriate port(s) on the rear panel of the Echotrac E20.
Do not disconnect any cables from the rear of the Echotrac E20 while the unit is
running. This can damage the internal workings of the unit.
The critical connections are clearly marked on the unit and shown in Figure 5.

For safety purposes, the Echotrac E20 must be connected to protective earth. The
protective earth pin in the DC connector is the protective conductor terminal of E20.
The LEDs for the SYNC port and the three COM ports will only be lit, when the E20 is
connected to power.
