    Introduction MIport PCI serial interface cards allow you to add RS-232, RS-422 and RS- 485 interfaces to Windows based computers equipped with a PCI bus. Depending on your choice of card one, two or four optically isolated serial ports, or two, four or eight non-isolated serial ports, can be added. MIport PCI serial cards are Plug and Play compatible, which allows the Windows Operating System and driver to set the addresses and IRQ used by the card.

    Serial Card Setup In half-duplex operation, the receiver is disabled during transmit (RX and enabled when not transmitting. In full-duplex operation the receiver is always enabled (RX ON). Since RS-485 transmitters are tri-stated when not transmitting, the receive inputs must be biased to ensure the media floats in the Mark state so that the first Space state is detected correctly at the start of the next transmission.

    RS-232 Mode In RS-232 Mode MIport serial ports function as buffered standard PC serial ports and operate as DTEs (Data Terminal Equipment). RS-232 interfaces are commonly used for communications with modems, serial printers, and computer-controlled devices such as security equipment, bar code scanners and point-of-sale devices.

  • Page 62: Rs-232 Signal Designations

    RS-232 Connections/Operation RS-232 Signal Designations The primary RS-232 signals are with GND (ground), they often are referred to as a “3-wire” interface. (Request to Send) and lines used to indicate to the other device that data can be sent or received. These lines may be enabled or disabled on a byte-by-byte basis and are used to prevent buffer overrun or the loss of data.

  • Page 63: Rs-232 Signal Levels

    RS-232 Signal Levels RS-232 signal lines are referenced to ground, and each signal can alternate above and below ground. The RS-232 standard specifies output voltages must be no less than +5 volts and no greater than +25 volts to represent a Space on a transmit line (or an asserted handshake line).

  • Page 65: Rs-422/485 Mode

    RS-422/485 Mode In RS-422/RS-485 mode MIport serial ports provide two sets of differential signal pairs and signal ground for each port. The RS-422 and RS-485 standards use balanced differential drivers and receivers for each signal. This facilitates greater communication distances than unbalanced systems such as RS-232.

  • Page 66: Chapter 8: Rs-422/485 Connections/Operation

    RS-422/485 Connections/Operation RS-422/485 Signal Designations Typically RS-422 and RS-485 interfaces use five lines including two signal pairs and ground. One signal pair is the transmit pair, labeled . The other signal pair is the receive pair, labeled TD(B)+ Signal ground is labeled RS-422/485 Differential Signals In RS-422 and RS-485 interfaces signals are sent on differential pairs.

  • Page 67: Rs-422 Operation

    RS-422 Operation In RS-422 mode, the transmitter is enabled (TX ENABLE) all the time, and the receiver is enabled (RX ENABLE) all the time. Typical point-to-point connections use a transmitter and receiver at each end with two wire pairs connecting them. The transmit lines of the device at one end of the link are connected to the matching receive lines of the device at the other end.

To check 2-wire RS-485 RS-422 or 4-wire RS-485 Loopback Connections, you must either enable the receiver by moving the receive jumper to RX ENABLE mode, or use one port to transmit to another 2-wire RS-485 port or converter by cross connecting and loading ComTest twice, one copy for each port.

    Setting the DIP Switches on RS-232/422/485 Ports Set the DIP switches to configure the desired operating mode as follows: Switch 1 422/485 Switch 2 TX On TX SD Switch 3 RX SD RX On RS-232 Mode 422/485 TX On RX On RS-422 Mode Figure 54.

  • Page 80: Dip Switch 3 (Rs-232/422/485 Ports)

    For RS-485 operation the middle DIP switch is placed in the TX SD position. In this position the transmitter is only enabled when data is being sent. The transmitter is tri-stated when not sending data, allowing other transmitters on the communications line to transmit without interference. DIP Switch 3 (RS-232/422/485 ports) The bottom DIP switch (3) configures the port for half-duplex (two-wire) RS-485 operation or full-duplex (four wire) RS-422/RS-485 operation.
  • Page 81 DIP Switch 1 (RS-422/485 only) The top DIP switch (1) configures the port for RS-485 or RS-422 operation. For RS-422 operation (which uses two wire pairs and sends point-to-point or point-to-multipoints) the transmitter can be enabled all the time. Placing the middle DIP switch in the TX ON position accomplishes this.
