Measurement Specialties Inc. NetScanner System (9016, 9021, & 9022) User’s Manual
6 - 3
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.
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.
