Optional IO33X front plug-ins allow a variety of digital (TTL, LVDS, CMOS), RS485/RS422, and analog functionality to be added to IO33X FPGA I/O modules.
Optional IO3XX rear plug-ins allow the digital lines of the IO3XX FPGA I/O modules to be accessible from the front of the enclosure, and convert them to TTL, RS422 or RS485.
