The successful SCU V4 processor has been upgraded to provide the latest performance capabilities available from PC technology.

The Seanet SCU V5 provides a reliable, rugged and easy to install replacement to the SCU V4, it has been designed as a robust 19" rack mount unit with floated shock mount sub assemblies for maximum reliability.

A high-speed 156kBits/sec communication system is used within the Seanet SCU, allowing a full suite of Tritech sensors to be operated over a single twisted pair or, by utilising the Tritech MultiComm, over an RS232 / Fibre-Optic interface. Each device connected to the Seanet SCU runs, in real time, in its own onscreen window. The monitor display may be varied to show single or multiple windows and this can be altered at any time during normal operations. This multiple-sensor capability provides obvious cost benefits as well as reducing the space requirement for consoles in the control room.

The Seanet SCU is a multi-tasking control unit running under a Microsoft Windows XP operating system. Fitted with a 'LAN card' the SeaNet SCU provides easy access to data storage and data transfer.

The Seanet SCU retains the use of the industry favourite Remote Access Terminal (RAT) a feature of the SCU V4. The RAT provides full control of the SeaNet SCU and its ergonomically designed layout ensures that all functions are well placed and easy to use. The built in mini-joystick on the RAT provides a useful tool for carrying out range and bearing measurements on sonar data. If preferred the RAT may be detached from the SeaNet SCU processor allowing it to be operated from a more desirable location.


Manuals, Datasheets, Software, etc.


On new systems, Seanet Pro, the Tritech software that runs on the SCU, is looking at Com Port 1 for sensor information. If it doesn’t find any it reports the TMO error that you are seeing. If you do have a Tritech unit connected to that port which isn’t working, please contact our Customer Support Team (on +44 (0) 1224 744 111 (option 2), or

If you do not have a Tritech unit connected to that port you can either ignore the error or disable the Com Port in the Seanet Pro software by doing the following:

  • Go to the Utilities drop down menu and select Com Setup
  • For the AIF device that has Com Port 1 selected, ensure that the Enable box is unchecked
  • Close the Com Setup window
