Pressure Systems, Inc. NetScanner™ System (9016, 9021, & 9022) User’s Manual

NOTE: NetScanner ™ System modules are factory-configured to use a
200.xxx.xxx.xxx IP address with a 192.0.0.0 subnet mask. These addresses
were chosen with the understanding that the modules would run on a
totally private network. Addressing errors may occur if modules are
connected to a company internal network or if the modules are connected
to the Internet. If you are not sure about the configured networking
scheme, please consult your network administrator.
protocol is slightly more complicated since it requires a Dynamic IP server to be present and properly
configured on the network. Before host communications can be established, the user must ensure
that the 9016 or 9021/9022 has been assigned a known IP address through either Static IP or using
a Dynamic IP server.
To determine whether Static or Dynamic IP addressing is enabled, observe the module Tx LED on
module power-up. As explained in Section 6.1.1, if Dynamic addressing is enabled, the module Tx
LED will flash one or more times during the power-up sequence. If the module receives a valid
reply, the Busy (BSY) LED will begin to flash rapidly (appearing dim) and the Tx LED will remain
OFF. If it appears the module received an IP server reply or that it is configured for the Static IP
(default) addressing, proceed to Section 6.1.2.2 to verify proper host TCP/IP configuration.
If the module does not receive a response to a Dynamic IP addressing request, its Tx LED will
continue to flash with an increasing delay between Tx attempts. The Busy (BSY) LED will also
remain OFF until a Dynamic IP addressing reply is received. If a Dynamic IP reply is not received,
verify that a Dynamic IP server is present on the network. If the IP server is present, verify that it
contains an entry for the 9016, 9021, or 9022 Ethernet hardware (MAC) address. Verify this address
against the Ethernet address printed on the module label to ensure it has been entered correctly into
the Dynamic IP server. After making the required changes to the IP server, repeat the above steps
until the module receives a valid Dynamic IP reply.
If the user wishes to manually change the factory set IP address in a module, it may be done with
the NUSS application program (described more fully in Section 6.1.2.2). To use it for this purpose,
select the desired module on the application’s screen map (left window), then press (click) the right-
mouse button to get the module’s pop-up context menu. From the NUSS menu, select Configure/
Network Options. A new screen then appears that will accept a new IP address (and other network
parameters). After the new address is sent, the module must be “re-booted” (another choice on the
context menu) before it will take effect.
