IFR converters
Description: IFR devices convert the levels of the RS232 standard to the corresponding levels of the RS485 standard. IFR converters allow the connection of a PC equipped with RS232 to an RS485 bus. The activation of the RS485 drivers can be done with RTS, RTS denied or automatically if this option has been selected with internal jumpers. In the automatic option, data from the RS232 line activates the drivers. When the data transfer is finished, the IFR converters return to receive mode.
