Net232 provides a means of connecting ChartScan, TempScan, and MultiScan data acquisition devices to
the ethernet. This guide will show you how to configure your Net232’s address, connect the Net232 to your
acquisition device, identify the four basic network scenarios, and connect your system to the ethernet. The
final page of this document includes Net232 product specifications.

For successful Net232 operations, your computer needs to have the following:

•

•

•

•

•

Although this guide provides instructions for connecting the acquisition device to the ethernet,
you may need to refer to your device user’s manual for additional instructions, such as DIP
switch configuration for RS-232 serial communications.

Check Your Order

If you have not already done so, carefully unpack your shipping carton and check all contents for damage which may
have occurred during shipment. Immediately report all damage to the shipping agent and your sales representative.
Retain all shipping materials in case the unit must be returned to the factory.
The Net232 package should contain the following, depending on your order:

Install Software

Use Microsoft Windows Run dialog box to configure Net232’s address and install the ChartView program group.
Direct Windows to run the SETUP.EXE file found on Installation Diskette 1 (or CD-ROM, if applicable). Follow the

Early in the setup you will be prompted to enter your Registration ID Number. This number appears on your Network
Registration Sheet (1035-0971) and must be entered to enable ChartViewNET.

If you ordered ChartView Plus, enter the registration ID number as it appears on your ChartView Plus Registration
Sheet (1035-0970). Otherwise, press Next and continue to follow the screen prompts.

Configure Net232’s Address Settings

Prior to configuring the Net232 and connecting it to your network, use the PING utility (provided
by Windows
another device.

Example:

For a given address: aaa.bbb.ccc.ddd, enter as follows from
the DOS prompt:

C:> PING aaa.bbb.ccc.ddd

If no other device is using the address, the PING utility will
report a “device time out” and a 100% loss of data. Any
other response indicates that a device on the network is
already using the IP address, and that you will need to use
another address.

Using the NetScan Configuration Utility

Net232 must be configured before putting it to use. Configuration is accomplished through the NetScan Configuration
Utility. The utility installs after you select “Net232” as your device type.
You can access the NetScan Configuration Utility from Window’s desktop Start Menu, as follows:

Start ⇒⇒⇒⇒ Programs ⇒⇒⇒⇒ ChartView ⇒⇒⇒⇒ Interface Configuration

The utility’s window displays a “welcome” prior to prompting you through the required configuration steps. The
following steps appear in the utility’s screen prompts. Note that each “step” has a corresponding tab (see following
figure).

). The PING utility will inform you if your intended address is already in use by

The network interface must be properly configured before Net232 can communicate with a
computer via the ethernet.

Step 1

a) Connect an RS-232 serial cable to an available serial communication port (COMM Port) on your
computer. Note that CA-47 cables cn connect to 25 pin COMM ports or 9 pin COMM ports.
b) Connect the other end of the RS-232 cable to Net232’s CONFIG port (PORT 1).

Step 2

a) Cycle Net232’s power switch “Off,” then “On.”
b) In the NetScan Configuration Utility, check (3) the on-screen box that states, “I have performed the

actions described above.”

Step 3

Basic information regarding TCP/IP Addressing for Net232 is presented below. If you
have any difficulty regarding address settings, please contact your network
administrator.

a) Review the following terminology as needed, then proceed to step 3b.

Protocol

The Net232 uses TCP/IP (Transport Control Protocol/Internet Protocol) for communications over the
ethernet. You can access Net232-connected devices from virtually anywhere in the world since the World
Wide Web uses this same protocol.

TCP/IP addressing consists of three parameters: the IP address, the Sub-net Mask, and the Gateway
Address. Each of these parameters consists of four different numbers which range from 0 to 255. The
numbers are typically represented in a dotted decimal format, for example: 192.88.247.11.

IP Address

The IP (Internet Protocol) address is unique to one specific device on the network, and can not be shared by
any other device on the network. The only restrictions on the IP address are:

1) the first number must be between 127 and 255

2) the last number must be between 1 and 254.

Sub-net Mask

The Sub-net Mask determines how many addresses are on the network. Note that Class C networks consist
of up to 256 addresses; and are quite common. For a Class C Network the

255.255.255.0. All computers on the network must have the same
