Description

Matching device between the communication port and the connector on the back board

The present invention relates to a matching device between a communication port and a connector on a back board, and more particularly, to a matching device between a communication port formed of a redundant structure and a connector on a back board.

In general, a communication port in an electronic device is used as a channel for transmitting and receiving data to and from an external terminal device through a connector of a predetermined standard (for example, RS-232C) provided on a back board. The duplication of such communication ports is caused by duplication of function boards employing the communication port.

1 is a system block diagram including a communication port having a duplex structure according to duplication of a function board and a connector between connectors on a back board as described above, and illustrates the case of 16 ports.

That is, FIG. 1 shows first and second communication port providing units 101 and 102 and first and second communication port providing units 111 and 112 that provide communication ports to transmit data in units of eight channels, respectively. The first and second functional boards 100 and 110 having a redundancy control structure having a) and the connector 180 on the backboard are illustrated as examples. The operation is as follows.

First, the first functional board 100 transmits data in different 8 port units through the first communication port providing unit 101 and the second communication port providing unit 102, respectively, and the second function board 110 is also used. Although the second 'communication port providing unit 111 and the second' communication port providing unit 112 are configured to transmit data in different 8-port units, respectively, the first function board 100 is active due to the redundancy control structure. In the active state, the second function board 110 is set and operated in the standby state, and when the first function board 100 is in the standby state, the second function board 110 is set and operated in the active state. do.

As a result, the first multiplexing logic circuit 120 is controlled by an active / standby mode control signal provided from a redundancy control unit (not shown) included in the first functional board 100 so that the first multiplexing logic circuit 120 is disposed within the first functional board 100. The first communication port providing unit 101 and the first 'communication port providing unit 111 in the second function board 110 are selectively connected to drive data to be transmitted.

The second multiplexing logic circuit 150 is also controlled by an active / standby mode control signal provided from a redundancy control unit (not shown) provided in the second function board 110 so as to control the second multiplexing logic circuit 150 in the first function board 100. The communication port providing unit 102 and the second 'communication port providing unit 112 in the first function board 110 are selectively connected to drive data to be transmitted.

The first transmit / receive processing unit 130 and the second transmit / receive processing unit 160 convert the signals received from the first multiplexing logic circuit 120 and the second multiplexing logic circuit 150 in a manner employed by the connector 180. The data transmitted to the connector 180 or transmitted from the connector 180 is converted into a form of data that can be recognized by the first and second function boards 100 and 110.

The first and second DTE / DCE mode setting units 140 and 170 are configured for a data terminal equipment (DTE) and a data circuit terminating equipment by a connected terminal mode selection control signal applied by a main processor or an operator (not shown). Mode is set, and data transmission / reception processing is performed between the first and second transmission / reception processing units 130 and 160 and the connector 180. In this case, DTE is the final terminal device in the data transmission section, and the final processing of data on the communication line. Usually, CRT, PC, and printer, etc., DCE is an intermediate device for data transmission. By giving, it is usually modem or mux.

However, such a matching device is provided separately between the function board and the connector, and requires a separate cable between the function board and the first and second multiplexing logic circuits. There was. This problem is more serious when adding ports.
