System Start-up
When the GT4 system is powered on, a bootloader runs which loads the Linux operating system. This runs
start-up scripts to set up and congure the terminal and to start enabled services.
When an application is installed and once the unit is fully booted, the initial screen gives you the opportunity
to enter the Terminal Setup by pressing the F8 key. If no key is pressed, the system times out and
automatically runs the installed application. See below:
Press F8 for Set-Up Menu Factory App Launch Screen
If no application is installed, the terminal continually displays the prompt to enter the Terminal Setup.
With the Factory App installed, the following keys are active from the launch screen:
F3 (USB Setup): Installs application from a USB memory stick. This option is only available if a USB
memory stick with an application installation package is tted. See “Deploying/Conguring Terminal with a
USB Memory Stick” on page 23
F4 (Exit): Exits the application momentarily, thus allowing the user to access the terminal’s set-up menus
for system conguration. See “Terminal Setup” on page 8
F7 (Net Setup): Allows network download of an application by specifying ID and PIN. See “Deploying a
Terminal Using a Network Connection” on page 23
F8 (Info): Accesses Info pages on the Application, Firmware, Health and Network status.
The set-up menus allow the terminal conguration to be changed at the terminal.
Note: Once connectivity is achieved between the terminal and a remote computer, the terminal can be
congured remotely either by downloading data using server software (such as Custom Exchange) or by
using tools such as SSH and AssistIT. (See “Remote Connections” on page 19)

these if you are setting up remote connections. See
“Remote Connections” on page 19. Note that by
default only NTP is enabled.
Note: Before enabling any service, consider any
associated security risks, which will depend on the
network the terminal is installed in.
Terminal Setup
Services Menu
AssistIT Enable this for Grosvenor’s comprehensive remote support feature.
The AssistIT service uses port 5222/TCP to connect to the server and
port 7777/TCP for VNC, Shell and LogView data. For AssistIT to work
fully, these ports must not be blocked.
Telnet Enable this to run a shell on the terminal from a remote computer. This
needs to be enabled if the development environment is being used.
The Telnet service listens on port 23/TCP.
Telnet is not secure and should only be used for debug/development
purposes and should not be left on.
NTP Enable this if the terminal is to acquire its time and date using the
Network Time Protocol. If enabled, the terminal will try to connect to the
default pool.ntp.org server on the Internet. The NTP service uses port
123/UDP to connect to the server. For NTP to work this port must not
be blocked.
SSH Enable this to run a Secure Shell on the terminal, which allows remote
users to log in to the terminal’s shell securely. SSH provides a secure
alternative to Telnet and does not transmit passwords in plain text.
A SSH client program is required on the remote computer. The SSH
service listens on port 22/TCP.
VNC Enable this if you wish to control the terminal from a remote computer.
The remote computer will need to run a VNC client program, such as
UltraVNC Viewer. Once connected, the display on the terminal can
be viewed on the remote PC and the keypad on the terminal can be
operated remotely. The VNC service listens on port 5900/TCP.
VNC is not secure and should only be used for debug/development
purposes and should not be left on.

Terminal Setup
Internal reader Special Decoders
Type 1 – Passthrough. This causes the data stream generated by
the reader to be passed directly to the application as an ASCII bit
stream. This allows the application to decode the data in situations
where the reader encoding is not yet supported by the rmware.
This option is also a useful tool for data format analysis.
Type 2 – Bitmask decoder. Enables a pre-dened bitmask to be
applied to a reader data string that is of an unsupported format, in
order to obtain the desired transponder number
External reader Displays information on connected extrernal readers.
Test reader This enables the congured reader to be tested. The user should swipe/
present badge and the decoded data is displayed on the terminal’s
display, for example:
#2 0004405100693
(2nd swipe same badge)
#1 0004405100693
(1st swipe of badge) is shown (bit length, decoder used, and so on)
Biometric
The terminal automatically detects whether a biometric reader is tted. If detected then the following
selections can be made, otherwise the message No biometric unit installed will appear.
Info Module: Displays the model/rmware details of the biometric reader.
Test Sensor This prompts the user to place their nger on the reader. Once read,
the user’s template is shown on the display, for example:
Note that this process does not enrol the user, but by displaying a
representation of the ngerprint, it can be used to conrm that the
reader is working correctly and is not damaged.
Calibrate Sensor This option allows recalibration of the biometric sensor and is normally
only used following sensor replacement.
Delete all Templates This option allows the user to permanently delete all templates in the
biometric reader. Use this option with care!

Remote Connections
The recommended method for remotely connecting to a command line shell in the terminal is to use SSH.
Using SSH
On Windows platforms the free program PuTTY can be used.
To connect, specify the IP address of the terminal e.g. 172.16.3.49 (Note: Omit any leading zeros). Once a
connection has been initiated, you are prompted to log into the terminal and are prompted for a login name
and a password.
Login: root
Password: 00000088 (for example)
The user name is root and the password is the
numeric part of the terminal serial number located
inside the terminal at the top of the motherboard.
We strongly recommend that you change the default password, see “The Login Password” on page 21.
Once you are logged in, shell commands can be run.
Note: The SSH service must be enabled as part of the terminal conguration. See “Services Menu” on page
11.
Using AssistIT
Enabling the AssistIT service allows the support representative to interrogate the terminal’s conguration, as
well as access to other remote control services. Full instructions on how to use this feature can be found in
the AssistIT User Manual.
Note: The AssistIT service must be enabled as part of the terminal conguration. See “Services Menu” on
page 11.
Using Telnet
The log-in messages are the same as the SSH session.
Note: The Telnet service must be enabled as part of the terminal conguration. See “Services Menu” on
page 11.
Using Telnet is not secure and not recommended.

Page 20
Remote Connections
Using VNC
If the VNC service is enabled on the terminal it is
possible to control the keyboard remotely by using a
VNC Client viewer program on the remote computer.
The example below uses UltraVNC viewer to
remotely control the terminal. The connection screen
is as follows:
Once connected, the remote terminal’s live display is
shown in a window on the computer’s desktop. The
keyboard on the remote computer causes the same
key to be pressed at the terminal.
In the example below, pressing F8 at the computer
will cause the terminal to enter the Info menu.
