EOT-706: Engine Order Telegraph System

Overview

The Engine Order Telegraph (EOT) provides means for autonomous bi-directional communication of speed orders and replies between the Wheelhouse/Bridge, Engine Control Room (ECR) and/or Engine Room (ER).

Features

  • Single or twin screw operation
  • Multiple stations
  • Bi-directional RS-485 serial communication between stations
  • Auto dimmer
  • Membrane keypad
  • Lamp test
  • Voyage Data Recorder (VDR) Interface (optional)

Operation

Commands are initiated by pressing the respective command buttons on the wheelhouse panel. These commands are transmitted via a two-wire serial interface to the engine room panel. The engine room stations will blink the corresponding LEDs and activate the beacon and siren until the command is acknowledged. The LED will then stop blinking and the alarm muted.
