  • Page 9: Autogating

    This chapter details the specifications of the PCI quad RS422/485 card and explains how to configure the RS485 Multiplex jumpers present on both cards. These half-sized cards will work happily in any PCI 2.0 or greater compliant PC compatible. ½ Four independent 9 pin D RS422/485 Serial ports.
  • Page 10 Multitasking operating systems, like Windows 95, Windows NT, OS/2 and UNIX, cannot successfully use the RTS line to control the gating of the PC’s transmitter. Whilst they can set the RTS line true just before the data transmission starts, they cannot set the RTS line false quickly enough after the data has gone.
  • Page 11 PIN 9 - CLEAR TO SEND (CTS+) 37 Way D Connector PCI cards require no hardware configuration for IRQ and address allocation - this is done automatically at start up by the PC. However, the PCI quad RS422/485 has four sets of jumpers for configuration of RS485 multiplex modes for each port, how to configure these jumpers is shown below.
  • Page 12 The RS485 Multiplex jumper block, is shown below with default settings of no jumpers present (both ports full duplex). Where: TX/RX1+ and TX/RX1- control port 1 RS485 multiplexing. TX/RX2+ and TX/RX2- control port 2 RS485 multiplexing. TX/RX3+ and TX/RX3- control port 3 RS485 multiplexing. TX/RX4+ and TX/RX4- control port 4 RS485 multiplexing.
  • Page 13 Then using a screwdriver, remove the cover mounting screws on the back panel of the PC system unit. Next, remove the PC’s cover by sliding it forward and up. It usually helps to disconnect the keyboard from the PC since it tends to get in the way when the case is removed.
  • Page 14 Choose an empty expansion slot. This Card will fit into one of the white PCI slots on your motherboad. Remove the blanking cover protecting the slot on the PC back panel. KEEP the blanking cover screw safely for later. Now insert the card in the slot. Be careful to ensure that the gold plated pcb fingers fits neatly into the I/O expansion connector.

  • Page 17 /I IRQ, range specifies card interrupt and COM port range. The COM port range specifies the COM port(s). Range may be a single port OR a range of ports. /B number buffer is used to set the number of pairs of buffers to be allocated to ports and is a decimal number in the range 1-maxport.

  • Page 19 The Windows 3.x installation procedure consists of two steps after the PCI RS422/485 card is inserted: 1. Determining the resources that the PCI RS422/485 card has claimed. 2.Informing Windows 3.x of those resources. Whenever certain values have been entered or changed in the hardware settings window, a message prompting to restart Windows will appear.

  • Page 23 The Delete button can be used to discard the entries of ports that have been removed from the system. Note. Never try to leave out a serial port number when using the delete button, because Windows may automatically shift serial port numbers which results in a mis-match of settings in the Serial Ports Applet (COM1-COM4 only).

  • Page 51 The RS422 standard defines a serial communications standard. RS422 is a high speed and/or long distance data transmission. Each signal is carried by a pair of wires and is thus a differential data transmission system. Over distances up to 40 feet the maximum data rate is 10 Megabits per second, and for distances up to 4000 feet the maximum data rate is 100 Kilobytes per second.

There are several schemes for connecting RS485 devices depending on the characteristics of the system. In many cases there will be only one device, which can transmit, data and all the others simply listen to it.
  • Page 55 The RS485 many talkers, many listeners, Full Duplex system can be used when all the RS485 devices have separate Transmit and Receive channels. There is NO multiplexing of the TXD and RXD signals on the same device. This system is especially useful when there is no flow control available on the PC, usually due to the use of a third party communications program that prevents the use of the RTS signal as a "transmit enable"...
