USB to NMEA 0183

Advanced technology for safe, reliable and simple connection to your PC...




What is the default baud rate of the USG-2?

The USG-2 has no firmware and therefore no default baud rate.  The COM port will need to be opened at the baud rate that matches the device connected to the USG-2.

Can I buy a third party USB lead to use with the USG-2?

While a standard type B USB plug can be used with the USG-2, this is not recommended.  Standard USB leads will not provide the same level of ingress protection that the Actisense USB lead has been designed to as it is provided with a rubber 'O' ring seal on the connection to the USG-2.

Can I connect devices to the USG-2 that communicate at different baud rates?

No.  Devices connected to the USG-2 input and output must communicate at the same baud rate.


Can I connect more than one Listener (receiving device) to the USG-2?

Yes.  The USG-2 will support up to eight Listeners (depending on the demand from the Listener).  To ensure safe isolation of all Listeners and that enough power is available, we recommend the use of an Actisense NBF-3.


Can I connect more than one Talker (transmitting device) to the USG-2?

No.  It is not possible to connect more than one Talker to a Listeners input in any NMEA 0183 network. A multiplexer, such as the Actisense NDC-4, is required to combine multiple Talker outputs in to one.


What features exist to aid fault finding?

The USG-2 is fitted with three LEDs, one for indication of power and two for indication of data (one for TX, one for RX).  Please refer to the USG-2 User Manual for full details.


How waterproof is the USG-2

The internal electronics of the USG-2 are potted and sealed to provide a high level of water/ingress protection.  The high quality, shielded USB lead included with the USG-2 also provides a similar, high level of water protection when mated with the high retention USB receptacle.

The pluggable screwless connector meets all requirements  in accordance with  EN 60068-2-11:

If the device is going to be used in an environment where it is going to be subjected to direct contact with water splashes etc. then it is recommended as a preventative measure that silicone grease (or dielectric grease) is used.
