- 🌐 Introduction: The Simrad EA500 (part number 382-083003) display and Ethernet control unit is engineered for high-precision hydrographic surveying, scientific echosounding, and marine navigation applications, delivering reliable data visualization and robust network communication in harsh maritime environments.
Product Parameters & Datasheet
- 📐 Dimensions: Standard marine console-mount chassis measuring approximately 450mm x 350mm x 200mm.
- ⚖️ Weight: Approximately 12.5 kg.
- 🌍 Country of Origin: Norway.
- ⚡ Power Supply Rating: 115 VAC to 230 VAC nominal input frequency 50/60 Hz (or 24 VDC variant dependent on ship power configuration).
- 🔧 Installation Style: Panel flush-mounting or console bracket installation.
- 🌡️ Operating Temperature: 0^\circC to +50^\circC.
- 湿度 Humidity: Up to 95% non-condensing relative humidity in marine atmospheres.
- 🛡️ Ingress Protection: IP54 front panel protection against water spray and dust ingress.
- 🔌 Communication Interface: Multiple Ethernet ports, serial NMEA ports, and dedicated transducer interface connections.
- ⚡ Power Consumption: Approximately 120 W under operational load.
Application Fields
- Hydrographic survey vessels and oceanographic research ships.
- Bathymetric mapping and seabed classification projects.
- Commercial navigation and deep-water depth sounding operations.
- Marine engineering and port authority channel monitoring.
Product Precautions
- Verify that shipboard power mains match the unit’s nominal voltage requirements prior to switching on the system.
- Ensure the console installation area provides sufficient airflow to prevent excessive heat buildup during prolonged operational cycles.
- Protect all rear-panel Ethernet and transducer cable connections from direct moisture exposure and excessive mechanical strain.
- Clean the display screen using designated anti-static, non-abrasive cleaning agents to avoid damaging the specialized anti-glare coating.
Parameter Configuration & Modification Methods
- System parameters, range settings, and Ethernet network configurations are managed directly through the graphical user interface via the front-panel control trackball or connected keyboard/mouse peripherals.
- Calibration settings for sound velocity, transducer depth offsets, and data output formats are modified within the setup menu and saved to internal system storage.
Manual/Automatic Mode Switching
- Transitioning between manual ping control, manual gain adjustment, and automated bottom-tracking or auto-gain routines is executed via dedicated menu selections on the main operator interface.
Emergency Trip / System Shutdown
- Safe Power Down: The system should be shut down using the software-initiated shutdown procedure before cutting main power breakers to prevent file corruption on the operating disk. Hardware emergency power interruption is handled via shipboard central bridge breakers.
Frequently Asked Questions (Q&A)
- Q: How are network settings adjusted for external data sharing?
A: Ethernet communication parameters, IP addresses, and telegram output rates are configured through the network setup menu on the main display interface.
- Q: Can the unit operate with multiple transducer frequencies?
A: Yes, depending on the transceiver module configuration connected to the system, multi-frequency support can be managed through the control unit.
- Q: What data formats are supported for external logging?
A: The unit supports standard hydrographic data output formats and proprietary Simrad data logging telegrams via Ethernet and serial connections.
