Detector to an existing Ethernet network, you will need to know
which type of cable you are using.
The ProStar 325 Detector uses TCP/IP (Transmission Control
Protocol / Internet Protocol) to communicate over the Ethernet
network. The term TCP/IP refers to the software protocol that
allows various devices to communicate with each other.
Communications over the Internet and the World Wide Web use
TCP/IP. Since the ProStar 325 Detector uses TCP/IP to
communicate with the Star Workstation, the Workstation PC and
the ProStar 325 Detector need to be given unique IP addresses —
the addresses that are used to identify each networked TCP/IP
device. This manual describes the process by which you give the
PC and Detector unique IP addresses.
You may connect your Workstation and ProStar 325 Detector
directly to each other.
We refer to this type of special purpose network as an isolated
network (one that does not have IP addresses prescribed by a
Network Administrator).
You may also connect your Workstations and ProStar 325
Detectors to an Ethernet network used for purposes other than
instrument control (such as Internet access or file server access).
We refer to this type of multi-purpose network as a company
network, and a Network Administrator in your company will
typically manage it. If this is the case, then follow the
instructions for configuring your ProStar 325 Detector and
Workstation for use on a company network.
The ProStar 325 Detector is provided with its IP address either
by the Star Workstation or by software running on your network.
The software used to send IP addresses to TCP/IP devices is
called a BOOTP Server (Bootstrap Protocol Server). You will see
the term BOOTP Server mentioned in this section. If you are
connecting your ProStar 325 Detector and Workstation to a
company network, your Network Administrator should be made
aware that the ProStar 325 Detector will require a BOOTP
Server for IP address assignment.
3.9.2 Where to Begin
Before beginning the configuration process, you should know
whether you will be attaching your Workstation and ProStar 325
Detector to a company network (as described in the previous
section) or an isolated network only used for instrument control.
If you have a Network Administrator on site, you may wish to ask
which configuration is recommended.
If an Ethernet card has not been installed and configured on your
PC, read Installing and Configuring the Ethernet Card in Your
