Claims

[Scope of utility model registration request]

The connector connected to the signal line on the R3232C side and the R3
Input and output terminals connected to the signal line on the 422 side,
a switching means for switching a signal jumper by switching the position of a setting pin connected to a pin of the connector depending on whether the signal on the R3232C side is in a transmitting state or a receiving state; and inputting through the connector. a first signal conversion means that converts the R3232C level signal into a TTL level signal, converts it into an R3422 level signal and sends it to the R3422 side through the output terminal; and an R3422 level signal input through the input terminal. After converting the signal to TTL level, this is converted to R323
Convert it to a 2C level signal and pass it through the connector to the R
A data transfer adapter comprising a second signal conversion means for sending to the 3232C side.
