1 INTRODUCTION
1.1 About this Manual
This manual contains a detailed description of how to install and complete the electrical connections of the GT7.2x00
and GT7.3x00 terminals. The different options for configuring the terminals as well as the technical data are also
provided herein.
As the configuration of the GT7.3x01 (installation variant with different housing) is identical, this manual is also valid
in large parts for this variant. However, the assembly and ordering instructions for this variant are available in a
separate document (VB_GT7-3x01-EN+EN).
Henceforth, the term “GT7 terminal” is used to refer to the GT7.2x00, GT7.3x00, and GT7.3x01 terminals
collectively. If information is applicable to a particular terminal type, this will be noted.
The configuration and operation of the various apps available for the GT7 terminal, which determine the functionality,
are described in separate manuals. In these manuals, you will find further information on the respective app.
The installation and operation of other GT7 terminal variants and the various mounting accessories (e.g., mounting
brackets) are also described in separate documentation.
1.2 Chapter Overview
In chapter "2 GENERAL INFORMATION", a functional description and an overview of the GT7 terminal system as
well as an explanation of the key terms used in this manual can be found.
Chapter "3 INSTALLATION" contains the installation instructions for the GT7 terminal, i.e., how the GT7 terminal is
installed on-site.
Chapter “4 ELECTRICAL CONNECTIONS" contains instructions on how to connect the power supply, network
cabling, and external devices to the GT7 terminal.
Provided in chapter "5 CONFIGURATION" are the different configuration options and parameters for the GT7
terminal.
Chapter "6. TECHNICAL DATA" lists the technical specifications and shows the measurement diagrams of the GT7
terminal.
1.3 Target Groups
This manual contains information relevant for the different stages in the operating life of the GT7 terminal.
Information regarding the installation, commissioning, and configuration of the GT7 terminal is separated into

2 GENERAL INFORMATION
2.1 Intended Use
The GT7 terminal is a multipurpose device that allows different functions to be implemented through the installation
of various apps. The intended uses include:
- The control of turnstiles and doors(G7 Access App).
- The display of locker information orvisitor information (G7 Info App).
- The timedcontrol of devices such as solariums andspas (G7 Time App).
- The display of a countdown for using time-limited services such as showers and power plates (G7 Countdown App).
- The central reader in a networked locker system (G7 Central Locker App).
- The acquisition and display of personnel time and attendance information (G7 Time & Attendance App).
- Aninterface for gathering customer feedback (G7 Customer Feedback App).
- The enrollment and writing of fingerprint data onto users’ data carriers (G7 Enrollment App).

2.3 Functional Description
In order to activate a function on the GT7 terminal, e.g., to open a locked door, to view information, or to use a time-
controlled device, the user must first identify themselves. Identification can be performed in a variety of ways: using
data carriers with the RFID reader (Radio Frequency Identification) of the GT7 terminal, via NFC (Near Field
Communication), or with a barcode scanner (e.g., ATR 110/200 barcode scanner).
Following identification, further operation, such as the selection and confirmation of functions, is completed directly
on the device by touching the display. The ultra-clear touchscreen intuitively guides the user through the clearly
structured levels of the app. The wide range of executable apps (see “2.1 Intended Use”) allow the flexible use of the
terminal. Depending on the application, the GT7 terminal can operate as a standalone device or forward authorization
decisions on via the network to a control software, e.g., Relaxx. The communication can occur via Ethernet or Wi-Fi.
The GT7 terminals are suitable for both indoor and protected outdoor use. Every installation requirement is covered
with the various terminal models and holders provided to surface mount, flush mount, pole mount, or table mount the
GT7 terminal.
The configuration of the terminal can be completed on the device itself with limited settings or the full range of
settings are available via a web browser (web interface) or via the GANTNER Cloud (G7 Connect). Through the
configuration, the functionality of the GT7 terminal can be customized to the respective requirements.
2.4 Device Overview
The number designation of the GT7 terminals indicates the type of terminal. The number contains the following
information.
GT7.abcd -> a … Number of inputs/outputs: "2" = Standard equipment, 1 relay output, 1 optocoupler input
"3" = Additional to "2": camera, 2 relay outputs instead of 1,
WLAN, microphone, Wiegand interface (can be used as a status
input), RS-232
b … RFID reader technology: "3" = LEGIC advant and Proxy reader
"5" = MIFARE (ISO 14443) and ISO 15693 reader
"7" = LEGIC advant Proxy and HID iCLASS reader
c … Type: "0" = Standard (no additional reader)
"2" = Additional barcode reader
"3" = Additional fingerprint reader
d … Housing: "0" = Standard surface-mounted housing
"1" = Flush-mounted variant
2.5 Terminology
Some terms are used frequently in this manual and these are defined below.
GT7 Terminal
This term refers to all variants of the GT7.2x00, GT7.3x00, and GT73x01 model ranges, regardless of which app is
currently active. Since the configuration of the GT7.3x01 (built-in variant) is identical to the GT7.2x00 and GT7.3x00,
this manual is also valid in large parts for this variant. However, the installation and order information for this variant
are available in a separate document (VB_GT7-3x01-EN+EN).

- TheGT7terminalshouldnotbe exposed todirect sunlight. Otherwise,limitationsinthereadabilityof the displaycanoccur.
- For GT7 terminals installedoutdoors, the electrical installation andany empty conduits mustbe sealed airtight (e.g., with
silicone) topreventcondensation inthe terminal.

3.3 Installing the Rear Part
If the GT7 terminal is being installed in an outdoor area or another location that is not protected against dripping
water, the wall gasket (2) must be used (see Figure 3.1). Proceed with the following steps:
►Remove the protective foil from the back of the wall gasket.
►Attach the wall gasket onto the back of the rear part as shown in Figure 3.1. Ensure that the gasket sits flat
between the domes of the housing.

3.4 Attaching the Front Part
This section describes how to complete the installation by attaching the front part and RFID reader cover. Before
completing these steps, first connect the connection cables. For more information, see chapter "4 ELECTRICAL
CONNECTIONS”.
CAUTION! Electrical shock. The electrical connections must be made in a de-energized state.
NOTE! Ensure that the electronics and printed circuit board of the GT7 terminal are not damaged or scratched
during assembly.
►Check that the gasket (3), which is inserted in the inner edge of the front part, and the central connector (4) are
clean and undamaged.
CAUTION! Do not use liquids for cleaning.
