PROBLEM TO BE SOLVED: To bidirectionally and remotely operate a variety of onboard equipment from the outside of a vehicle or a variety of equipment outside the vehicle from the inside of the vehicle through a digital telephone set. SOLUTION: A data adapter for performing data communication through digital telephone sets 2 and 5 is provided with input circuits 14 and 44 for inputting various data and output circuits 15 and 45 for outputting various data. Thus, according to the data inputted from the input circuits of the 1st data adapter, the equipment connected to the output circuits of the 2nd data adapter can be controlled and oppositely, according to the data inputted from the input circuits of the 2nd data adapter, the equipment connected to the output circuits of the 1st data adapter can be controlled. Namely, a variety of equipment can be bidirectionally and remotely controlled through this data a dapter. |
