Note pins 1,6,9 - no connection

Note that only one of the RS232 or RS485 connectors can have
a cable connected at any one time in order to comply with Class
B EMC emission standard (EN61000-6-3, residential, commercial,
and light industrial environments).
WARNING: Failure to comply with this requirement will reduce
the unit to Class A (industrial environments); in a domestic
environment the unit may cause radio interference, in which
case the user may be required to take adequate measures.
If the IQ3/XNC/SER controller and its slave units are in the same
cabinet using the same power supply, each device should have
a good physical earth (ground) connection.
