1-10 Configuring and Starting NetScan NetScan User’s Manual
3) Private LAN Setup with Multiple Networks
Private LAN with Multiple Networks
In multiple-network scenarios, two or more networks connect to a common gateway via ethernet hubs. In
regard to multiple networks, a qualified network administrator should assign all TCP/IP parameters.
4) LAN Setup with Internet Access
LAN Setup with Gateway Access to Internet
In internet access scenarios, a network adminstrator usually assigns TCP/IP parameters. Configuring for
this scenario is identical to that of scenario 2 (Private LAN Setup), with the following exception: The
internet access scenario requires the gateway address to be set to the address of the gateway (router) device
that handles routing to the internet.
Connect Channel Signal Inputs
Connect channel inputs to your signal conditioning cards. Each signal conditioning card can support up to
16 Channels. With use of the expansion chassis, you can have up to 8 signal conditioning cards.
Depending on the type(s) of cards used, your connections will be made via one or more of the following:
screw terminal, mini-plug, BNC, or safety jack type input connector.
Reference Note: Chapter 7 contains information regarding each type of signal conditioning
card that can be used with NetScan.
NetScan has eight digital input lines and thirty-two digital output lines available on the rear panel DB-50
connector (see pin-out, below).
Each digital output line will drive five (5) standard TTL loads. All digital input lines are one-eighth (0.125)
TTL loads. All inputs are protected against damage from high static voltage. Normal precautions should be
taken to limit the input voltages to the range of 0.0 to 5.3 volts. All digital I/O lines are referenced to the
connector’s ground pins.

Do not exceed the 0.0 to 5.3 volts levels described above. Exceeding these levels may
damage the NetScan unit in a way not covered by the warranty.
Note: A CSN/Relay is available for high current alarm output applications. If used, this card must be
installed in the bottom slot of the NetScan’s main chassis. Installation instructions for CSN/Relay
are on page 1-3 of this manual. Refer to chapter 7 for detailed information regarding the
CSN/Relay card.
