Infrared communication adapter
First Claim
1. An infrared communication adapter, comprising:
- a portable telephone side communication interface for carrying out a serial data transmission by connecting with an external communication interface provided in a portable telephone, in accordance with a serial data transmission protocol of the portable telephone;
an infrared communication interface for carrying out a data communication with an external equipment having an infrared communication interface in accordance with an infrared communication protocol; and
a data processing section for carrying out a data process to transmit a data supplied from one communication interface of the communication interfaces, to the other communication interface;
wherein the data processing section comprises;
a protocol conversion unit for analyzing a communication protocol of a data supplying side communication interface and for converting the analyzed communication protocol into a communication protocol corresponding to a data receiving side communication interface; and
a data conversion unit for converting a serial data supplied from the portable telephone side communication interface, into a data which can be transmitted in accordance with the infrared communication protocol, to transmit the data to the infrared communication interface, and for converting a data supplied from the infrared communication interface, into a serial data which can be processed by the portable telephone, to transmit the serial data to the portable telephone side communication interface.

Abstract
It is to provide an infrared communication adapter which can carry out a data exchange with an external equipment having an infrared communication interface even though a portable telephone does not have an infrared communication function. The infrared communication adapter comprises a portable telephone side connecting section 4 for transmitting a serial data supplied from the portable telephone by connecting an external communication interface of the portable telephone; an infrared communication interface 3 for carrying out a data communication with the external equipment in accordance with the infrared communication protocol, wherein in order to transmit the data supplied from one communication interface to the other communication interface, the adapter analyzes a communication protocol of the communication interface disposed on the data supply side and carries out an RS232C emulation internally to transmit the data by converting the analyzed communication protocol into a communication protocol corresponding to a communication interface disposed on the data receive side.
