Every NetScanner



System Intelligent Pressure Scanner contains a Host Port, allowing it to be

interconnected in a network with other modules and a host computer. Models 9016, 9021, and

9022 have an Ethernet Host Port using TCP/IP and UDP/IP transmission protocols.

2.3.4.1 Ethernet Host Port Hookup

The Ethernet Host ports of every model 9016, 9021, and 9022 Intelligent Pressure Scanner

module, and its host computer, may be interconnected in a “star” network via a standard 10-

Base-T interconnection hub or switch. These standard devices will have their own power

requirements. Such a hub treats the host computer connection and all NetScanner

System

module connections alike. Ethernet communications pin assignments for the 9016, 9021, and

9022 electrical connector are shown in Figure 2.2. See Figure 2.3 for typical network topology.

The host and each module must have a unique Ethernet Hardware Address (a.k.a. MAC Address)

and a unique IP Address. The Ethernet Hardware address is generally fixed (at manufacturing

time of the Ethernet microprocessor board inside the module). The Ethernet Hardware address is

shown on each module’s label. The Ethernet Intelligent Pressure Scanners are capable of

supporting various methods for IP address assignment, using either the factory default (static IP

addressing) or user-configured Static IP addressing or Dynamic IP address assignment. Dynamic

IP address assignment is through the use of RARP or BOOTP protocols. Unless your

application requires the use of Dynamic IP address assignments, it is strongly suggested that the

module be left configured for the Static IP address protocol. This default method is typically

the simplest method for using the Intelligent Pressure Scanner.

In the Static IP addressing mode, the module will use a factory default IP address on power-up.

This default address is set to 200.20x.yyy.zzz where x is derived from the module type (0 for
