Use a serial cable to connect one of the WAN ports on the enterprise router to the
RS-232 serial connector on the ES450.
Note: The ES450 is a DCE serial device. The enterprise router may have an RJ-45 or DB-9 console
port. Depending on the type of console port connectors and the cable available from the enterprise
router vendor, you may need to purchase additional cables, including a null modem cable from the
enterprise router vendor.

Virtual Ethernet Connection with USB cable
If you are using the Ethernet
port on the ES450 device to
connect an enterprise
router, then use the USB
port to connect the PC
and configure it to be a
virtual Ethernet port.
If you are not using the Ethernet
port on the ES450 to connect an
enterprise router, the easiest way
to connect the PC is to use an
Ethernet cable.
