Background information: There are many cases where it is necessary to equip the ports of an interface card with different port models. It may for example be necessary to use COM1 as a 20mA programming interface for a PLC, as the software used only supports this port, while COM2 is connected to a serial RS232 mouse. For such requirements, W&T provides a very smart solution without any need for additional external hardware. The module concept of the serial W&T PC cards allow you to freely select the interface model, as the PC card mainboard is equipped with pluggable modules that convert the internal TTL signals into interface signals. The combined interface cards are supplied fully configured according to your specifications and are ready for installation. You can change a built-in port at any time by simply replacing the interface module.
