Introduction

This document provides a “road map” for setting up a PointScan data acquisition system that is made
up of the following elements:

1. PointScan/100 and PointScan/200 series hardware modules,

2. KEPServerEX server software.

3. DASYLab client software.

This document is called a “road map” because it provides top-level directions to guide the user
through the setup process. Each software package (IOToolKit, KEPServerEX, and DASYLab) provides
more detailed setup information through on-line help screens.

This road map is designed for users who have the following system configuration:

• Both the DASYLab and KEPServerEX software packages are running on the same computer.

• The computer and the PointScan modules are connected using an Ethernet LAN (Local Area

This document covers the setup process for two network cases, (1) “Dedicated” LAN and
(2) “Shared” LAN. For most of the steps the instructions are identical. When differences do exist, the
steps for each case are clearly indicated.

Be sure to follow the steps as applicable to your LAN. If you are uncertain as to whether the LAN is
“Dedicated” or “Shared,” please consult your network administrator. The figures on the following two
pages should clarify any confusion regarding the type of LAN (Dedicated or Shared).

“DEDICATED” LAN

“Dedicated” LAN refers to an Ethernet Local Area Network that is dedicated solely to the PointScan
system and to no other device. The following 2 figures are examples of “Dedicated” LAN setups.

Dedicated LAN, with no HUB/Switch

Note: A “Crossover” Ethernet Cable is used in this setup.

Dedicated LAN, with Ethernet Hub/Switch

Note: Standard Ethernet Cables are used in this setup.

“SHARED” LAN

“Shared” LAN refers to an Ethernet Local Area Network that is used by both the PointScan system and at least
one other non-PointScan device.

Shared LAN

Note: Standard Ethernet Cables are used in this setup.

Step 1) Hook up the PointScan Hardware

Follow the hardware instructions in the PointScan User Guides to set up the module bases and to
connect sensors to PointScan units. If you do not have a copy of those documents, you can find PDF
versions at our website:
page until you see PointScan manuals.

Two very important hardware configuration steps are located in the PointScan/100 Series User’s
Manual, p/n 1085-0901. The steps can be found on pages 1-2 and 2-1 of that manual, respectively.

(a) Connecting the operating power to the modules.
(b) Connecting RS485 communications wiring between multiple modules.

If you are connecting your computer directly to a single PointScan/100 module,
you need to use an Ethernet crossover cable (instead of a standard one). If you
have more than one /100 series PointScan module in your system, you will need
to use an Ethernet hub or switch to connect the computer and PointScan
hardware to the network.

If you have any PointScan/200 series modules in your system, you must have a
PointScan/440 module to configure them. If this is the case, connect the 440
module to your computer’s serial port.

Never add PointScan modules to an active system, which is communicating with
KEPServer. Prior to adding modules, power-down the on-line modules and stop
the KEPServer communications.

Up to 7 PointScan modules can be powered by one PointScan/443 power supply module. Each
PointScan module requires approximately 140ma of current from the power source. You will need to
budget your available supply power accordingly, especially if you plan on using the same power supply
for external transducers and/or current loops.

Whenever an un-powered PointScan/443 module is plugged-in, it will only
power up to 4 connected modules. Attempting to startup more than 4 modules
will result in a power-stall condition, in which the /443 module cannot produce a
high enough output voltage. However, there are two methods for powering up
more than 4 modules. Both are discussed in step 2, below.

Avoid unnecessary power cycling of PointScan systems, as these systems are
designed to receive a continuous, uninterrupted supply of power. Returning
power to a system of 5, 6, or 7 modules will likely result in a power-stall
condition. Refer to the following step in regard to power start up.

Up to 32 modules using RS485 communications can be daisy chained from the RS485 port of one /100
series module. The /100 series modules provide the connection to Ethernet.

Step 2) Power up the PointScan Hardware

Up to 7 PointScan modules can be powered from one PointScan/443. However, the same is not true
for system startup. Plugging in a PointScan/443 that supports 5, 6, or 7 modules will most likely
result in a power-stall condition. If your system has 5 or more modules you will need to
employ one of the following methods to power up the entire system.

Method 1 - uses a power output switch:
(a) Ensure that the PointScan/443 is removed from its AC power supply.
(b) Place an on/off switch in the /443’s 24 VDC power output line.
(c) With the switch open [and up to 7 modules connected] supply AC power to the /443.
(d) After the /443 is powered, close the 24 VDC power output switch.
(e) Check the LEDs on the modules to verify their status is normal.

Method 2 - does not make use of a switch:
(a) Ensure that the PointScan/443 is removed from its AC power supply.
(b) Ensure that no more than 4 modules are connected to the system.
(c) Plug the /443 into its AC power supply.
(d) Check the LEDs on the modules to verify their status is normal.
(e) If applicable, connect the additional module(s) one at a time. Make sure that no more

than 7 modules will be connected to a single PointScan/443.

(f) Check the LEDs on the newly added modules to verify their status is normal.
Status LEDs are detailed in the PointScan hardware User’s Manuals.

Step 3) Set up Ethernet communications between your Computer

and the “Ethernet-Connected” PointScan/100 module(s)

PointScan/100 modules can be used in either an “Ethernet-connected” mode
or an “RS-485 connected” mode.

In this step each PointScan/100 module discussed is used in the
“Ethernet-connected” mode.

Determine the IP addresses for PointScan/100 modules

By default, the PointScan/100 modules are shipped with an IP (Internet Protocol) address of 10.1.0.1.
This address is stored in the base of the /100 module. If your system has only one of these /100 modules
and you have a direct connection from the computer to the /100 module, there is no need to change this IP
address. However, if you have more than one PointScan/100 module take action according to whether
your LAN system is “dedicated” or “shared.”

“DEDICATED” LAN “SHARED” LAN

For “Dedicated” LAN systems: If you have
more than one “Ethernet-connected” PointScan
/100 series module, you will have to change the
IP address of the second and following modules
to 10.1.0.2, 10.1.0.3, and so forth.

See Step 6, part g on Configuring /100 Series
modules using IOToolKit.

For “Shared” LAN systems: You must obtain a
set of unused IP addresses from your network
administrator. Then you must change the IP
address of each “Ethernet-connected” PointScan
/100 series module to one of these unused
addresses.

See Step 6, part g on Configuring /100 Series
modules using IOToolKit.

Set up the IP address for your computer

Your computer’s IP address needs to be fixed, not a dynamic one chosen by DHCP or other means.
To set this fixed address to one that is compatible with the PointScan/100 modules:

1) Open the Windows Control Panel and double-click the Network icon.

2) Navigate to the TCP/IP Properties window for the Network Interface card you are using.

3) Select the option labeled “Use the following IP address.”

4) Enter the following numbers for “Dedicated” or “Shared” LAN, as applicable to your
system:

“DEDICATED” LAN “SHARED” LAN

IP Address: 10.0.0.1
Subnet Mask: 255.0.0.0

Use an IP Address and Subnet Mask
provided by the network administrator.

5) Close out the Network window and the Control Panel. Make sure that you disable any firewall
programs or other software that might restrict traffic on the Ethernet port.

Screens Pertaining to Internet Protocol

IP Address and Subnet Mask shown are for a “Dedicated” LAN. For
”Shared” LAN obtain IP Address and Subnet Mask values from your
network administrator.

Step 4) Install the IOToolKit Software

(a) Insert the IOToolKit CD (p/n 1075-0601) into the CD drive on your computer. If the CD does not

auto-start use Windows Explorer to browse to the contents of your CD drive. Then, open the IO
Tools Install folder and double-click on the Setup.exe file [in that folder].

(b) Follow the prompts to complete the installation.

At some point after the installation you need to register your IOToolkit software.
This is done from the IOToolkit Help>Registration Window.

PointScan Road Map 878395 7

Step 5) Start up the IOToolKit Software

Start the IOToolKit by going to the Windows Start menu and then selecting Programs > IO Tools.
The IOToolKit is used to set up the configuration of each PointScan module in the system. It also

downloads the configuration to the module base.

Step 6) Configure each Ethernet [PointScan/100 Series] Module

using IOToolKit

Most of the IOToolKit windows have a Help button you can press if you are not sure how to select some of the
parameters.

(a) Start the configuration process by running the Plug and Play Wizard in IOToolKit. You do this by

selecting Tools, then Plug and Play Wizard; or by clicking on the Playing Card icon.
(b) Select <Add a new station to the project> and click <OK>.
(c) Select the type of module to be added. Note that the PointScan/100 series modules are all of the

Ethernet I/O Module type.
(d) If this is the first module you are adding to the project, IOToolKit will ask you to save the

configuration as a Project File. Select a file name (use the extension *.6pj) and click <Save> to

save the project file away.

TIP: Perform the File/Save Project action several times during the configuration
process to ensure the project is saved with your most recent configuration
settings.

(e) Fill in the parameters in the General tab, then click <Next>:

Station type – Select the PointScan/100 series module being used.
Station name – Any alphanumeric string up to 20 characters can be used.
Serial number – use the serial number printed on the front of the base of the /100 series

module, just above the power wiring.

Station number – start with number 1, then increment for other stations in the system,

whether /100 or /200 level stations. It is very important that the station number is set
correctly when you have multiple modules interconnected using RS485. The station
number must correspond with the number that represents the module’s position in the
RS485 link. The first module that connects to Ethernet is always station one, and each
additional module that is connected using RS485 takes the next consecutive station
number in order.

Com timeout – 3 seconds is usually adequate (click on Help for more info)
