Benefits

• Flexible configuration options to buffer autoswitch or combine NMEA data
• ISO-Drive separates the Listener from the Talker to protect both the PRO-BUF and each connected device.
• Fast bi-directional data connection to a monitor and control software application
• PRO-BUF can be configured using any web browser on any Operating system
• Works out-of-the-box without configuration for basic installations, or can be easily user configured as required
• Relay output is compatible with on-board alarm systems and NMEA Alarm sentence can be displayed and actioned on an MFD
• Easy to access via network, doesn’t require the device to be moved or have a serial connection to the PC.
• Quick visual check gives the user confidence that each input and output is passing data
• Features can be utilised to fine tune data, avoiding data overloads on the outputs and connected listeners
• Allows automatic data priority selection between two devices of the same type of data (e.g. GPS)
• Shows the NMEA 0183 on each I/O Port, and how frequently it arrives, great for low level diagnostics
• Allows use on large vessel 24V DC power supplies systems
• Additional features in future firmware revisions are accessed using a simple update process via Actisense Toolkit over Ethernet
• Fast installations and supports both screw and screwless terminal types. Ideal for quick diagnostic swapping
• Increased durability, ease of installation and high performance
• Can be installed on vessels governed by Class Society Rules
