Abstract

A data communication system comprises a portable device for effecting radio communication, a communication adapter card for storing therein a plurality of communication protocols corresponding to a plurality of communication systems employed by the portable device, a computer in which the communication adapter card is inserted to execute data processing, and a connector cable composed of a first connector connected to the portable device, a second connector connected to the communication adapter card for outputting identification information to identify one of the communication systems employed by the portable device, and a cable for connecting between the first and second connectors.

Claims

1. A data communication system comprising:

a portable device for effecting radio communication;

a communication adapter card for storing therein a plurality of communication protocols corresponding to a plurality of communication systems employed by the portable device, wherein the communication adapter card selects one of the communication protocols on the basis of identification information;

a computer in which the communication adapter card is inserted to execute data processing; and

a connector cable composed of a first connector connected to the portable device, a second connector connected to the communication adapter card for outputting the identification information to identify one of the communication systems employed by the portable device, and a cable for connecting between the first and second connectors;

wherein the second connector includes a DIP switch for outputting the identification information by manually switching the DIP switch on the basis of the communication system employed by the portable device.

2. The communication adapter medium according to claim 1, wherein the connector outputs the identification information, the identification information comprising identities selected from the group consisting of a personal digital cellular PDC system, a personal handyphone system PHS Guarantee, and a personal handyphone system PHS Best Effort.

3. The communication adapter medium according to claim 1, wherein the second connector comprises two of the DIP switch, including a first DIP switch and a second DIP switch, and outputs the identification information by manually switching the first DIP switch and the second DIP switch.

4. The communication adapter medium according to claim 3, wherein the first DIP switch and the second DIP switch are located on a side surface of the second connector.
