In addition to the nominal interfaces, all serial W&T PCI cards provide additional serial TTL ports which can use interface modules to be converted into a standard port of any type.

These optional ports do not however have galvanic isolation between each other or to the PC.

The additional interface modules are connected to the interface card using flat cable and attached to a slot bracket in the PC housing. Both components can be ordered from W&T as a separate accessory.
