Console Port Use the Console Port to connect a remote (or local) terminal and perform
remote (or local) management. This port does not carry Ethernet traffic.
The Console Port uses a standard null modem cable. The port settings are
fixed and have these values:
■ Baud Rate: 9600
■ Data Bits: 8
■ Parity: None
■ Stop Bit(s): 1
If you are upgrading the firmware on the EPS using a local computer
connected by a null modem cable, the upgrade program configures the
communications port that you select on your computer (COM1 is the
default) to match these settings.
You can obtain the firmware upgrade program and instructions for using
it from this web site:
