Abstract
An interface converter for mutually converting between a first serial interface, such as RS-232-C interface, and a second serial interface, such as RS-422-A interface. The interface converter includes a second connector being connectable directly to a first connector attached to the first serial interface and a plurality of third connectors, each of which has a terminal arrangement matched to the second serial interface. The interface converter further includes a first receiving circuit for the first serial interface connected to the second connector, a first transmitting circuit for the second serial interface interconnecting the first receiving circuit with the third connectors, a second receiving circuit for the second serial interface connected to the third connectors, and a second transmitting circuit for the first serial interface interconnecting the second receiving circuit with the second connector. The first transmitting circuit and the second receiving circuit are controlled by control lines from the second connector via the first receiving circuit.
