NETWORK CONNECTION RECOGNITION METHOD, NETWORK SYSTEM AND NETWORK CONNECTION TERMINAL DEVICE

摘要

In the case where a plurality of devices are connected to a predetermined network, there is performed first processing of sending a command to an opposite party connected via the network to inquire a unit type or a subunit type, from a specific device connected to the network. There is performed second processing of sending a command corresponding to a type discriminated based on a response obtained by the first processing. There is executed third processing of determining a kind of the device based on a response obtained by the second processing. Thus, the kind of a connected device can be accurately determined using a command corresponding to the kind of each device. <IMAGE>
