RS232 Evaluation Kit

Hi, guys I'm exploring some Integrated Circuit to use it in an RS232 application, so I found that there exists this Evaluation Kit  DC827A-B, and I'd like to understand the connections in the schematic.

Specifically, in pg 4 there it is showed the schematic, and J1 represents the DB9 connector for stablish an RS232 communication. My doubt is: pin 2,  RD (RX pin as per the standard) is connected to T1out, but this T1out  is an output from the IC LTC2804, and there it is my confussion. So, if a pin is for RX operation, I understand it is used to receive data (so in one device I transmit with TX and at the other device I receive with RX), so in this case RD should be connected to a receiver pin, e.g, RXIN. What am I missing here?
