Background information:Due to their modular design, all W&T Com-Servers and most W&T PC cards can be equipped with various port types. In contrast to standard devices that are equipped only with RS232 ports, the interfaces of W&T equipment can be modified by simply replacing the existing interface modules with the desired ones.
