Abstract
In a connection device connected to a network mounted in a boat, a protocol of a connection device connected to a network mounted in a boat is identified based on a communication ID in a certain message transmitted through the network. A device protocol is determined in accordance with the protocol of the network. Data communication in the network is performed in conformity with the device protocol. Accordingly, when the connection device is connected to the network, the connection device automatically identifies a protocol of the network and operates appropriately. Therefore, upward compatibility is maintained and usability is improved.
Claims6
A connection device connected to a network mounted in a boat, the connection device comprising:
- a protocol identification section configured to identify whether a device protocol of the network is a first protocol or a second protocol;
- a protocol determination section configured to determine which of the first protocol or the second protocol that the connection device should use to communicate with the network based on the device protocol identified by the protocol identification section;
- and
- a data communication section configured to perform data communication with the network in conformity with both of the first protocol and the second protocol, including the device protocol determined by the protocol determination section;
- wherein the first protocol is a protocol that requires authentication at a time of connecting the connection device to the network, and the second protocol is a protocol that does not require authentication at the time of connecting the connection device to the network.
A non-transitory computer readable medium storing a program for performing, when the program runs on a computer in a network mounted in a boat, a method comprising the steps of:
- performing a protocol identification process while a connection device is connected to the network to identify whether a device protocol of the network is a first protocol or a second protocol;
- performing a protocol determination process with the connection device to determine which of the first protocol or the second protocol that the connection device should use to communicate with the network based on the device protocol identified by the protocol identification process;
- and
- performing a data communication process with the connection device to perform data communication with the network in conformity with both of the first protocol and the second protocol, including the device protocol determined by the protocol determination process;
- wherein the first protocol is a protocol that requires authentication at a time of connecting the connection device to the network, and the second protocol is a protocol that does not require authentication at the time of connecting the connection device to the network.
