    Technical Specification

    The Interfacecom RS232 To RS485 Converter allows RS-232 equipment to utilize RS-485 networks,

    oper-ating in either point-to-point or multi-point, 2-or 4-wire. The RS232 To RS485 Converter is

    one of the most cost effective RS-485 solutions on the market. Use with your standard PC or Laptop

    to control RS-485 devices directly with no special software required. Any standard communications

    software for your RS-232 serial ports will work. Plugs directly into standard DB9 male RS-232

    port that comes with your PC or convert any number of your RS232 ports on a multiple port card

    with DB9 connectors to RS-485. You can also make a RS-232 device a RS-485 device on a RS-485

    network.

    Overview and Applications

    Jumper JP1 Pin 1-2 (RBA) : ON = Enable Bias Resistor 680 ohm in RX(+),A(+) to VCC*

    OFF = Disable Bias Resistor

    Pin 3-4 (RBY) : ON = Enable Bias Resistor 680 ohm in TX(+) to Vcc*OFF = Disable Bias Resistor

    Pin 5-6 (RBY) : ON = Enable Bias Resistor 680 ohm in RX(-),B(+)to Gnd*OFF = Disable Bias Resistor

    Pin 7-8 (RBZ) : ON = Enable Bias Resistor 680 ohm in TX(-) to Gnd*OFF = Turnaround Control by RTS Signal

    Jumper JP3 Pin 1-2 (TYZ) : ON = Enable Termination Resistor 120 ohm in TX(+) to TX(-)*

    OFF = Disable Termination Resistor

    Jumper JP4 Pin 1-2 (TAB) : ON = Enable Termination Resistor 120 ohm in RX(+),A(+) to RX(-),B(+)

    OFF = Disable Termination Resistor

    Pin 9-10 (R/A) : ON = Automatic turnaround Mode*OFF = Turnaround Control by RTS Signal

    Pin 11-12(F/H) : ON = 2-Wire Half Duplex Mode Select*OFF = 4-Wire Full duplex Mode Select
