4.6 - Interface and Host Settings
The PTU-5 includes both an Ethernet connection and RS-485 communications. You may connect to your
PTU using either or both of these methods; the Web interface is only available when using an Ethernet
connection, and the terminal interface is only available when using a serial connection.
4.6.1 - Ethernet Connection
The PTU Ethernet connection uses a standard Cat-5 (RJ-45) network cable.
•
You may connect the PTU directly to a host computer or indirectly through a router, hub, etc.
•
The PTU will either accept IP addresses from a DHCP server or select its own IP address if connected
directly to the host computer.
•
If needed, you may use a coupling to extend the Ethernet connection on the breakout cable.
Connect, power on, and test the PTU using the Ethernet connection and Web interface as described in
“Ethernet Connection” on page 11
