Wiring 2100-XX stations into a dataloop with IN2000-XX stations

When adding a 2100-XX station to a IN2000-XX dataloop, please follow the terminal numbers in the installation guides and not the RX+, RX- etc labels written on the stations.

When the 2100-XX stations and 2100-IS converter were designed, it was decided to change to terminal numbers all to 70-73 so that data loop wiring was simpler.
However this meant that the RX and TX labeling was not the same as the previous IN2000-XX models, the 2100-XX installation guides provide terminal number connection information that shows the correct connections.
