Fig 2.4.2 RJ-45 Pinouts and Signals
As shown in the Figure 2.4.2, the RS-232 signal pins, TXD and RXD, are in the RJ45-L connector. Therefore, only the
RJ45-L can be used to connect to the remote PC or terminal when the RS-232 interface is selected. If RS-485 interface is
selected, both RJ-45 connectors will be used for the daisy-chained / cascaded RS-485 connections shown in the Figure
2.4.3.
