CONVERSION INTERFACE OF DATA TRANSMITTING DEVICE

摘要

PURPOSE: A conversion interface of a data transmitting device is provided to directly connect a system communicating by an HDLC packet with a general host to transceive data, and to make the one host monitor many cards and detect errors of the transceived data. CONSTITUTION: An EPP(Enhanced Parallel Port) interface(100) receives an address and a control signal from a host, and transceives data to output the data to an exterior, then inputs receiving data from the exterior. A transmitting buffer(FIFO)(110) inputs the transmission data from the EPP interface(100). A receiving buffer(FIFO)(120) outputs the receiving data to the EPP interface(100). An HDLC interface(130) reads the transmission data of the transmitting buffer(110) to convert the data into an HDLC format, and outputs the converted data. The HDLC interface(130) analyzes the outputted data, and outputs the same receiving data as the address received by the EPP interface(100).
