Data from the host comes out RS232 Ports 1 and 5 because of the 1+1 Port Backup. RS232
Port 1 can be connected to a local RTU. To get data downstream, connect RS232 Port 5 to
RS232 Port 2 or 6 with a 3-wire RJ45 to RJ45 crossover cable. See the table on page 1 for
pinouts. Connect the ground 1 to 1 or 7 to 7. Connect 3 to 5 and 5 to 3 to cross the data leads.
