제1도는 본 발명을 설명하기 위한 통신시스템 블럭도를 도시한 것이다.1 shows a communication system block diagram for explaining the present invention.

제1도는 호스트인 전송장치(10)와 단말장치(50)간의 통신을 위한 시스템이다. 그리고 통신포트(20,40)간에 트위스티드 페어 케이블(30)을 사용하여 접속한다. 트위스티드 페어 케이블(30)을 통하여 전송장치(10)와 단말장치(50)간의 데이타를 양방향으로 주고 받을 수 있으며, 트위스티드 페어 케이블(30)의 접속을 정의하기 위해서는 관련된 신호를 케이블에 접속되는 핀에 할당한다.1 is a system for communication between a transmission apparatus 10 that is a host and a terminal apparatus 50. Then, the communication ports 20 and 40 are connected using the twisted pair cable 30. The twisted pair cable 30 may transmit and receive data between the transmission device 10 and the terminal device 50 in both directions. Assign.

제2도는 종래의 송수신단자 할당방법의 일 예를 도시한 것이다.2 illustrates an example of a conventional transmission / reception terminal allocation method.

트위스티드 페어 케이블(30)을 사용하여 접속된 핀중에서 데이타를 전송하는 핀(Tx)와 수신하는 핀(Rx)을 반드시 Tx-Rx형태로 접속해야 한다. 제2도에서, 통신포트(20,40)의 단자에는 트위스티드 페어 케이블(30)을 스트레이트 라인(Straight Line)형태로 접속하기 위하여 단말장치(50)의 내부회로에서 서로 단자를 교차시켜 Tx-Rx형태로 데이타가 송수신되게 하였다.Among the pins connected using the twisted pair cable 30, the pin Tx for transmitting data and the pin Rx for receiving data must be connected in the form of Tx-Rx. In FIG. 2, the terminals of the communication ports 20 and 40 are connected to each other in the internal circuit of the terminal device 50 in order to connect the twisted pair cable 30 in the form of a straight line. Allow data to be sent and received.

제3도는 종래의 송수신단자 할당방법의 다른 예를 도시한 것이다.3 shows another example of a conventional transmission / reception terminal allocation method.

트위스티드 페어 케이블(30)을 사용하는 통신시스템에서 전송장치(10)의 통신포트(20)를 단말장치(50)의 통신포트(40)에만 접속할 수 있는 것이 아니라 경우에 따라서는 전송장비의 확장을 위하여 전송장치(10)들을 서로 접속할 경우가 있다. 이때, 제3도에서와 같이, 전송장치(10)들을 트위스티드 페어 케이블(30)을 사용하여 접속하되 서로 크로스시켜야 한다. 제3도의 케이블 접속은 제2도의 케이블 접속과 상이한 바, 서로 동일한 통신포트에 대하여 Tx-Rx형태로 접속하였다.In a communication system using a twisted pair cable 30, the communication port 20 of the transmission device 10 may not be connected to the communication port 40 of the terminal device 50, but in some cases, the expansion of the transmission device may be extended. In order to connect the transmission apparatuses 10 with each other. At this time, as shown in FIG. 3, the transmitters 10 should be connected using twisted pair cable 30 but cross each other. Since the cable connection of FIG. 3 differs from the cable connection of FIG. 2, it connected to the same communication port in Tx-Rx form.

그런데 케이블의 접속하는 경우가 스트레이트 라인형태 또는 크로스 라인형태등 다수이므로 실제 사용환경에서 케이블을 잘못 사용하여 통신시스템의 장애를 일으킬 수 있다는 문제점이 있었다.However, since the cable is connected in many cases, such as a straight line type or a cross line type, there is a problem that a communication system may be damaged by incorrectly using the cable in an actual use environment.

따라서 본 발명의 목적은 상술한 문제점을 해결하기 위하여 단말장치의 송수신단자의 할당을 전송장치의 송수신단자와 동일하게 할당하자는 것이다.Accordingly, an object of the present invention is to allocate the transmission and reception terminals of the terminal apparatus in the same way as the transmission and reception terminals of the transmission apparatus in order to solve the above problems.

상기 목적을 달성하기 위하여 전송장치와 단말장치를 구비한 통신시스템의 송수신단자 할당방법에 있어서, 상기 전송장치의 통신포트의 핀을 기준으로 하여 상기 단말장치의 송수신단자를 상기 전송장치의 송수신단자와 동일하게 할당하고, 서로 송수신단자간에 크로스형태로 접속함을 특징으로 한다.In order to achieve the above object, a transmission and reception terminal assignment method of a communication system having a transmission device and a terminal device, the transmission and reception terminal of the terminal device based on the pin of the communication port of the transmission device and the transmission and reception terminal of the transmission device They are assigned in the same way and are connected to each other in a cross form between the transmitting and receiving terminals.

이하, 첨부된 도면을 참조하여 본 발명에 대하여 설명하기로 한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

제4도는 본 발명의 일 실시예에 따른 송수신단자 할당방법의 블럭도를 도시한 것이다.4 is a block diagram of a transmission and reception terminal assignment method according to an embodiment of the present invention.

제4도의 구성에 대하여 설명하면, 단말장치의 송수신단자(TD+, TD-, RD+, RD-)는 전송장치의 송수신단자와 동일하게 할당한다. 또한 전송장치와 단말장치의 송수신단자간의 트위스티드 페어 케이블접속은 크로스형태로 이루어진다. 크로스형태로 접속하여 Tx-Rx형태로 데이타를 서로 송수신하게 된다.4, the transmission and reception terminals TD +, TD-, RD +, and RD- of the terminal apparatus are allocated in the same way as the transmission and reception terminals of the transmission apparatus.
