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.
Note: The Ethernet and serial interfaces may be connected simultaneously; however,
you should only use one interface at a time for command and control of the PTU.
Connect, power on, and test the PTU using the Ethernet connection and Web interface as described in
"Ethernet Connection" on page

4.6.2 - RS-485 Electrical Connection

The PTU RS-485 communications use the following connections:
• Duplex: full
• Connections: Tx+, Tx-, Rx+, and Rx-
• Voltage: RS-422 or RS-485 levels
Serial communication between the PTU and your host computer should be set as follows:
• Baud rate: 9600. You may adjust the baud rate using software commands. Please refer to the Pan-
Tilt E Series Command Reference Manual for instructions.
• Start bit: 1
• Data bits: 8
• Stop bit: 1
• Handshaking: off
