  • Page 3 W&T Serial PCI cards The gradual decline in ISA slots in modern PCs has made it ne- cessary to make the functionality of ISA cards available for the PCI bus as well. W&T has responded by creating an entire family of serial PCI interface cards which meet the needs of industrial automation through integrated galvanic isolation of the PC ports and the ability to equip the serial ports of the card with a variety of phy-...

  • Page 5 W&T Serial PCI cards Low Profile PCI cards: General characteristics Function All serial Low Profile PCI cards add the functionality of maxi- mum four additional serial ports to your PC. One of these ports (Port 1) is integrated on the interface card, whereas three addi- tional, optional ports (ports 2 through 4) are connected to the circuit board through ribbon cable.
  • Page 6 W&T Serial PCI cards Galvanic isolation and ESD protection Port 1 on all W&T Low Profile PCI interface cards is galvanically isolated from the PC with an isolation voltage of at least 1kV DC, whereas the optional ports 2 through 4 have no galvanic isolation from the PC.
  • Page 7 W&T Serial PCI cards where no ground potential differences can be expected. This would include any peripherals which are located in the direct vicinity of the PC and thus are powered from the same sub-di- vision as well as peripherals which are inherently potential-free. This generally applies to all devices which are powered from the interface or by a plug-in power supply.
  • Page 8 W&T Serial PCI cards Important notes The serial W&T PCI cards may be equipped only with the 18x1x series interface modules (e.g. 18811, 18813, 18611, 18411, etc.) which have a supply voltage of 5V DC. The use of 3.3V modules in the18x3x series (e.g. 18831, 18833, 18631, etc.

  • Page 13 W&T Serial PCI cards Low Profile PCI card 1x RS232/RS422/RS485, #13610 Function The W&T PC card model 13610 provides on port 1 a switchable serial RS232/RS422/RS485 interface with 1kV DC galvanic iso- lation. Ports 2 through 4 can also be used for any three non- galvanically isolated serial interfaces.
  • Page 14 W&T Serial PCI cards RS422 mode The PCI card supports one data and one handshake channel each (selectable DTR or RTS handshake output) in each direc- tion. The RS422 sender and receiver chips are always active. RS485 mode In all RS485 modes there is one data channel available in each direction.
  • Page 15 W&T Serial PCI cards RS485 4-wire mode / RS485 2-wire mode with echo, automatic control One data channel in each direction is available. The RS485 dri- ver chip is automatically activated for each data transmission and reset to tristate after data output is finished. The receive channel is always active in this mode.
  • Page 16 W&T Serial PCI cards Terminating All RS485 modes require terminating the bus system with a ter- mination network which ensures a defined rest state in the tris- tate phases of bus operation. The bus system can be connected to a termination network on the PC card by closing DIL swit- ches 6 and 7: Data In B Data In A...

  • Page 19 W&T Serial PCI cards Standard PCI cards: Common characteristics Function All W&T serial interface cards for PCI bus systems add the func- tionality of maximum four additional serial ports to your PC. Two of these ports (port 1 and port 2) are integrated on the interface card, whereas two additional, optional ports (ports 3 and 4) are connected to the circuit board through ribbon cable.
  • Page 20 W&T Serial PCI cards Galvanic isolation and ESD protection Ports 1 and 2 on all W&T PCI interface cards are galvanically isolated from each other and from the PC with an isolation vol- tage of at least 1kV DC, whereas the optional ports 3 and 4 have no galvanic isolation from the PC.
  • Page 21 W&T Serial PCI cards It must be noted however that the optional ports 3 and 4 are not galvanically isolated from each other or from the PC, so that these ports may be used only for connecting peripherals where no ground potential differences can be expected. This would include any peripherals which are located in the direct vicinity of the PC and thus are powered from the same sub-division as well as peripherals which are inherently potential-free.
