RS-485 Port Connection

There is a pair of DB9 ports in the ADAM-5000 system. The ports are designed to link the RS-485 through a cable to a network in a system. The pin assignment of the port is as follows:

Pin No.	Description
Pin 1	RS-485	Data -
Pin 2	RS-485	Data +
Pin 3	Not Used
Pin 4	Not Used
Pin 5	RS-485	Signal Ground
Pin 6	Not Used
Pin 7	Not Used
Pin 8	Not Used
Pin 9	Not Used

Note: The wiring of the RS-485 should be through a twisted pair. To reduce electrical noise, it should be twisted as tightly as possible
