Connect the serial COM port of your PC and the 700/7000 model switch using a standard straight through serial
cable. You will require a cable with a 9-pin or 25-pin sub-D female connector for the PC end, and a 9-pin male
sub-D connector for the 700/7000 switch model end.
The following table shows the pin-out and the connections for both types of cable:

and

Models
The 708M12 and 716M12 Industrial Ethernet Switches are fully protected against dust and will remain sealed when
immersed in water to a depth of 1 meter for 1 hour when all the ports are properly mated or sealed
For 708M12 and 716M12 units, remove the IP67 cap from the M12 port connectors and connect the Ethernet
cables. These IP67 caps seal off the unused ports protecting them from dirt, water, oil or any other contaminants
which might be present in close proximity of the switch.
