Example

The following example shows the settings on JA, JB, JC and JD where port 1 is terminated on RTS ± and TxD ±, the RS-422/485 port 2 is set for bias/termination on RTS ±, TxD ±, CTS ±, and RxD ±, the RS-422/485 port 3 is not terminated, and port 4 is set for RS-232 and therefore should not be terminated
