DEVICE FOR CONNECTING TO ANALYZE COMMUNICATION STATE OF AUTOMATED TELLER MACHINE

摘要

A connecting device for communication analysis of an ATM(Automated Teller Machine) is provided to analyze causes of a communication fault of the ATM communicating with external devices in an RS(Recommended Standard)-422 communication method through a protocol analyzer using an RS-232 data input/output method, by converting an RS-422 signal into an RS-232 signal. A connecting device(20) for communication analysis of an ATM is composed of an RS-422 connector(21) connected to an RS-422 output port of a communication module installed in the ATM; an RS-422/TTL(Transistor Transistor Logic) converter(22) connected to the RS-422 connector to convert an RS-422 signal into a TTL level signal; a TTL/RS-232 converter(24) coupled to the RS-422/TTL converter to convert the TTL level signal into an RS-232 signal; and an RS-232 connector(26) linked to a protocol analyzer by connecting one end to the TTL/RS-232 converter.
