The PRO-BUF-1 can be configured manually using the ‘Mode’ pins (also referred to as ‘hard-wiring’) or via the web browser based configuration tool. Manually configuring the PRO-BUF-1 takes priority over the web configuration tool. An internet connection is not required to access the configuration tool. The factory default setting of the PRO-BUF-1 is ‘Buffer Mode 3’...

If only a single input on the NDC-4 seems to be receiving data, please check that your NDC-4 is not in autoswitch mode. When in this mode, only data from input 1 will be used. This function is designed for when using more than one source of the same type of data, like a GPS for example. When the primary source on input 1 fails, it will switch to input 2...

We offer the NDC-4 preconfigured for AIS devices (product code: NDC-4-AIS). This will have "OPTO IN 2" set to communicate at 38400 baud by default and filters applied to this input to prevent the data appearing at "ISO OUT 1" as the large volume of data from AIS devices can quickly 'flood' the standard 4800 baud bandwidth at this output...

Connecting NMEA 0183 devices directly to a PC without isolation is not recommended as this can cause ground loops which will damage your PC and your NMEA 0183 devices. The Actisense USG-2 is a great device to overcome the issue of isolation with PC connections. The USG-2 has isolation on the input and output, keeping your devices safe from ground loops. The USG-2..
