Overview Introduction Weidmüller Serial/Fiber converters are equipped with a multiple interface circuit that can handle RS-232, RS-422, and RS-485 serial interfaces, as well as a multi-mode fiber. Serial/Fiber converters are used to extend serial transmission distance up to 5km.The Serial/Fiber converter must be configured to transmit a particular serial interface. You cannot transmit both RS-232 and RS-485 signals at the same time.
ATTENTION For Fiber Ring Users: To avoid problems when setting up a fiber ring, each Serial/Fiber Converter unit making up the ring must be powered down and set to “Ring mode.” Next, make sure all cables are connected properly, and then power up all devices connected to the ring. NOTE “Ring Mode” can only be used with half-duplex applications (i.e., RS-485 multi-drop communication).
IE-MCT-1RS232/485-1ST IE-MCT-1RS232/485-1SC Wiring Examples Connecting the Power Supply Before using the Serial/Fiber Converter, first connect the DC power supply to the power supply terminal block located on the Serial/Fiber Converter’s bottom panel.
DIP Switch Settings Serial Connection SW1 SW2 RS-232 RS-422 RS-485 4-wire RS-485 2-wire OFF ON OFF ON ON ON OFF OFF Built-in 120 Ω Terminator Enable Disable Ring mode Point to Point mode SW3 SW4 ON OFF – – – – ON OFF The S1 DIP Switch is located inside the Serial/Fiber Converter. When the Serial/Fiber Converter is in RS-485 mode, use this DIP switch to configure RS-485 data direction control, data format, and baudrate.
The S2 DIP switch is located inside the Serial/Fiber Converter. This switch is used to configure the pull high/low resistors. Note that S2 Pin 1 and Pin 2 must both be configured to ON or both must be configured to OFF. Pull High/Low Resistor 150K 1K (default setting) S2 Pin 1 OFF ON S2 Pin 2 OFF ON NOTE We recommend setting S2 Pin 1 and Pin 2 to the 1K option (ON/ON) when termination is enabled. LED Description There are 3 LEDs on the front panel of the Serial/Fiber Converter.
