Guardian Co-Deposition Controller Operating Manual
4.5 Computer Connections
Guardian requires a connection to an external computer via RS232 cable or
ethernet cable. If the EIES Guardian software is to be installed, please see
Installation on page 3-3 .
4.5.1 RS232 Serial Interface
Connect a serial cable from the Guardian serial port to the computer’s serial port.
The cable required is a DB9 female-to-male. A USB to RS232 converter is required
if the computer only provides the USB connection.
Guardian baud rate is fixed at 115,200. Communications format is No Parity, 8 bits,
1 stop bit.
4.5.2 TCP/IP Ethernet Interface
The TCP/IP interface supports only the Standard Ethernet TCP/IP protocol. The
Guardian will communicate via TCP/IP on TCP port number 2101. The interface
supports static addressing, DHCP is not supported. Ethernet parameters allowed
to be set are the IP address.
4.5.2.1 Network Connection
If the Guardian is connected through a network or hub connection, a standard
"straight" ethernet cable is required.
4.5.2.2 How to Set Up the Network Protocol on the PC
Most personal computers (PC) are configured to obtain the IP address, an address
which defines the computer on the Internet, automatically from a server.
To communicate directly with the Guardian, the Internet protocol (IP) on the PC
must be configured manually and an ethernet crossover cable (for example, IPN
600-1211-P5) must be connected between the PC and the Guardian. Some PC’s
will auto-configure and work with either straight or crossover cable. Instructions are
provided here for manually configuring the Internet protocol.
NOTE: If the PC only has one ethernet port (that is, one network connection) then
setting the PC for direct communications will prohibit it from accessing the
Internet until that setting is reversed.
NOTE: These instructions will set two values—the IP address and the Subnet
mask—which will most likely prohibit access to the Internet. If these values
already contain information then this information should be recorded
somewhere for use in restoring the Internet connection.
