Chapter 1
Defining Devices
Introduction

The FINsim POS Terminal Simulator supports multiple devices. These
can be defined using the “POS Terminals” option from the
“Configure” menu.
The basic design of the FINsim POS Terminal Simulator allows each
user to connect to a single EFT POS Terminal device. When making
changes to a terminal you only make changes to the device that you
are currently connected to.
If you need to apply a change to multiple devices, you need to connect
to each device in turn, make the change, and update the device.
Making a change to all devices at the same time is rare. In general
changes need to be made to a single device only.

Precautions

User Manual

Many of the settings in the device configuration screens must match
values set in your host software. Incorrect changes made to a device
may cause unpredictable results. Many fields on the device
configuration screens appear minor but can have a big impact on your
host EFT system.
The other issue with making changes to the device configuration is the
way that FINsim applies the changes. The software has been written to
be as dynamic as possible. There are very few instances where a
change to the device requires the program to be re-started to take
affect.

Backing up your
files

Once you have made your changes to the POS Terminal settings, it is
very important to make a backup of the configuration information. The
FINsim POS Terminal Simulator stores all the details of the devices in
the ATMServe.ini file which is saved in the Ini files directory pointed
to by the FINSIM_PATH environment variable. This directory was
specified during the set up process. This file must be backed up each
time changes are made to the devices defined in the simulator.
An option allows automatic backups to be taken of the ATMServe.ini
file. On the File Menu on the FINsim server, select the interval for
FINsim to create the backup copies of the ATMServer.ini file. When
configuration changes are made, the previous version of the
ATMserver.ini file is re-named including the Date and Time. If the
previous file was renamed within the backup interval it is deleted.

Creating new
devices

There are two ways you can create a new POS Terminal in FINsim.
You can create a new device from the FINsim – Connect To Device
screen by pressing the ‘Add Device” button (Refer to Volume 2 –
System Wide Features), or you can select an existing device, change
its name and press the ‘Add Device’ button on the Maintain Pos
Terminal Options Screen.
When you add a new device to the FINsim POS Terminal Simulator
the device that you had previously acquired when you selected “Add
Device” is released back into the pool. You are given control of the
new device. Any changes you make to the new device should be made
using the “Update” option.

General Terminal parameters
Introduction

The General terminal parameter dialog allows the generic information
about a device to be entered. This screen allows details about the type
of device and the communications protocol to be specified.
Based on the selections made on this screen the options offered on the
other Tabs of the Maintain POS Terminal Options screen will change.
For example, if the “Comms Protocol” is set to X.25, clicking on the
communications tab will display X.25 based parameters. If the
“Comms Protocol” is changed to, say, TCP/IP, the options presented
on the communications Tab will be for IP Addresses and port
numbers.

POS Terminal
Name

User Manual

The Device name can be up to 40 characters long. The name is case
sensitive so upper and lower case characters are considered to be
different.
The FINsim POS Terminal Simulator always presents devices in
alphabetical order.
You may find it useful to include your host computers device ID in the
name that you assign each device. This will make it easier to identify
the device.
When the FINsim POS Terminal Simulator is operating the name of
the selected device is set in the title bar of the main simulator window.

Message Formats The FINsim POS Terminal Simulator currently supports several
different terminal emulation modes. Each different terminal type uses
an internal script that GFG develop as part of the installation process
to simulate your terminals. You must select the correct terminal device
from this list.

Comms Protocol

The FINsim POS Terminal Simulator currently supports five different
communications protocols:






SNA
X.25
TCP/IP
Simulated NAC
WebSphere MQ

In addition to this an option for no communications is offered. This
can be used to temporarily disable a device from communicating with
the host. All current settings are remembered and when the original
protocol is selected the device will re-establish communications.
Each device defined uses its own communication link to the host.
Some networks require all devices to connect using a single
communications path. These networks use Hypercom Network Access
Controllers (NACs) to concentrate the terminal traffic. FINsim
supports this configuration. To set this up you define a device as a
“Hypercom NAC” and set the communications options for this device
to connect to your EFT switch. Each POS terminal has it
communications option set to “Simulated NAC” and routes its
messages via this communications path. The Simulated NAC device
will route the reply messages back to the original device.
