A connecting device for communication analysis of an ATM(Automated Teller Machine) is provided to analyze causes of a communication fault between the ATM and a host computer by using a protocol analyzer having an RS(Recommended Standard)-232 signal input unit, even if the ATM and the host computer use a CCL(Circle Current Loop) type communication unit. A connecting device for communication analysis of an ATM is composed of a CCL connector(21) coupled to a CCL output port of a communication module installed in the ATM; an external device connector(23) coupled to a host computer; signal lines(Ra,Rb,sa,sb) coupled between the CCL connectors to execute CCL communication; a first TTL(Transistor Transistor Logic) signal conversion unit(24) of which one side is connected with two of the signal lines and the other side is connected to one end of an RS-232 connector(27) through a TXD(Transmit Data) line; a second TTL signal conversion unit(25) of which one side is connected with a power stage of +12V and the other side is coupled to the other end of the RS-232 connector through a DTR(Data Terminal Relay) line; and a third TTL signal conversion unit(26) of which one side is connected with the rest of the signal lines and the other side is linked to the other end of the RS-232 connector through an RXD(Receive Data) line. |
