The serial interface is quite unusual in that it only uses one line for both sending and receiving. I looked at the data sheet and there isn't much technical info on the serial protocol, I think they assume you are going to be plugging it into one of their boards so you won't be too concerned about how it works. You could drive it with a pin on a different microcontroller but it would take a lot of work I think. A better device would have a SPI interface. This has serial input and output, and devices can be daisy-chained, which means you can use a dedicated serial transmit pin and a dedicated serial receive pin, which makes a lot more sense than trying to use one line as both input and output! Many micros have SPI functionality built-in.

They are not listed on the manufacturer's own website.
