Gemini Quick Start Guide

Overview

This Quick Start Guide is designed to take you through the initial
stages of setting up your Gemini Intercom system. More detailed
information is provided in the Implementation and Configuration
Guides which are provided on the CD included with your order.

Here is the outline of the steps you should follow:

o Unpack and visually inspect all equipment
o Create an IP Address plan for your intercom system
o Select a suitable PC to manage the system
o Install the Gateway Configuration Editor and database
o Configure your PC Firewall
o Create a configuration shell
o Set up each Gemini in turn and verify connection to the

database

o Connect to each Gemini using the Web Browser feature.

First Step – unpack and inspect

o Carefully unpack all boxes and inspect the equipment

carefully for any transit damage.

o Locate the despatch note (one per consignment) and

check that all items match your purchase order.

o You may find it helpful to record the serial numbers in a

safe place. These may be required at a later date if
additional options are purchased.

o Locate the product CD and make a note of the licence

number. You will need them later.

o At this point, do not power up the Gemini equipment.

Gemini Quick Start Guide

Network plan and IP addresses

The Gemini matrix frame will normally be connected to an IP
network. This allows it to communicate with other Trilogy IP­based intercom products and to connect to the Gateway
Configuration Editor software. However, once correctly
configured, a single Gemini matrix frame can operate in isolation.

Each Gemini frame requires a single static IP address. In addition,
if Gemini is fitted with optional Networked DSP, a further 2 static
addresses per Gemini are required.

Your laptop or PC must use an address in the same subnet
(“range”) as Gemini. If it is not convenient to adjust the address
of your PC then the default addresses used by Gemini must be
changed, as described later. Make a note of the values which you
plan to use.

IP

DSP 1

DSP 2

subnet

mask

gateway

address

Gemini

192.168.200.200

192.168.200.210

not set

Laptop
/ PC

192.168.200.100

n/a

255.255.255.0

not set

Any mistakes or inconsistencies in these values may lead to
unpredictable audio behaviour. For example, if you declare a
gateway address on your PC, this must also be declared within
the configuration data for Gemini. If your system includes IP
connected control panels, or multiple Gemini, the plan should be
extended accordingly.

Gemini Quick Start Guide

Management PC

PC manufacturers continually revise and update their
specifications making it difficult to give definitive guidelines. The
following specification is correct at date of issue (April 2016):

o Intel Core i3 or i5 CPU (or equivalent)
o 4 GB (min), 8 GB (preferred) Dual channel DDR3 RAM
o Windows 7 or later, 32 / 64 bit (preferred)
o Graphics with 512 MB supporting 1280 x 1024 resolution

on a 19” monitor

o CD / DVD reader for software installation

There are two software components to be considered:

o Gateway Configuration Editor. This is optimised for

Windows 7, 8, 8.1 and 10. Normally, Gateway only needs
to be active when changes to the system configuration
are planned.

o Database Supervisor. The primary task of this small

application is to prepare and package the data prior to
“pushing” it to each Gemini matrix. Ideally, the database
itself should be left running at all times. If it is shutdown
or disconnected, Gemini will continue to run using a
locally cached copy of the most recent data. However,
some functionality will be slightly restricted.

6

Gemini Quick Start Guide

Install Software

Two components will normally be installed:

o Gateway Configuration Editor
o Database Supervisor

For smaller systems, these components may be installed
alongside each other on a single PC. For larger systems it is
advisable to split the installation across two computers, so that
the database is left running continuously. If the database is shut
down or disconnected, there will be minor loss of functionality.
Gateway editor may be closed when configuration changes are
complete.

o Insert the supplied CD and from the menu, select the

option to “Install Software”.

o Select the two components listed above
o You should normally accept all other default

options

o The database runs as a System Service: to view and

manage the database, a small application (Database
Supervisor) is provided. You will find this at Programs >
Trilogy > Trilogy V5 > Database Supervisor.

o Once launched, a small additional icon will appear in the

PC system tray, next to the clock.

On first run, you will be prompted to enter your software licence
key code. This is supplied on the jewel case of the CD or DVD
which accompanies your order. Take a note of this and keep it
safe for any future re-installation.

Gemini Quick Start Guide

Configure the firewall

In order for Gemini to connect to the database, a number of ports
must be opened on the PC firewall.

o We can supply scripts to automate this process for the

Microsoft Windows firewall: for other firewalls please
consult the documentation supplied with that product.

o To carry out the task manually, the following ports must

be opened to allow inbound access:

o TCP 12005 management database data
o TCP 12006 management database control
o TCP 13001 management database supervisor

o Additionally, on any PC used for voice communication the

following ports must be opened to allow inbound access:

o UDP 2076 control and signalling
o UDP 2077 voice packets

o Finally, if the Virtual Panel application is installed, the

following port must be opened to allow inbound access:

o TCP 6822 Virtual Panel to host connection.

Gemini Quick Start Guide

Gateway – the Configuration Editor

o Start Gateway from Programs > Trilogy > Trilogy V5 >

Configuration Editor.

o Log-in using the default credentials Admin | trilogy
o A new “blank” configuration file will be created. Use the

simple editors by single clicking items in the “tree”.

o Open the editor for “Domain 1”: currently no Gemini

matrix hosts are present. Add hosts using the green “+”
button until the list matches your planned system.

o Highlight each host entry in turn and set the IP address.

Refer to the IP address plan created earlier.

o If Gemini is fitted with the optional Networked DSP

boards, they must be declared and their IP addresses
entered into the database.

See the next section for DSP configuration.

9

Gemini Quick Start Guide

Gateway – Networked DSP

o To configure any Networked DSP option boards, open the

Advanced Host Editor for Gemini by double-clicking the
corresponding icon in the “tree”.

o Alternatively, right-click the tree icon and select “Show

Advanced Editor”.

o Click on the “Audio” tab.
o As shown below, turn on the checkbox for Networked

DSPs and by reference to the initial plan, enter the IP
Addresses.

File Management

Any changes are posted to the database when you press the
“tick”. Once changes are posted, you can close Gateway at any
time and changes will not be lost.

o Backup the current configuration by pressing the red disk

icon, seen on the top toolbar.

o Establish a file naming convention which will help with

locating files in the future. For example, 20160325a
would indicate the first file created on 25

th

March 2016.

o Leave Gateway running: you will need it again shortly.

10

Gemini Quick Start Guide

Gemini – Setting the basics

o If you have purchased more than one Gemini, to avoid

any possibility of IP address conflicts, it is best to power
up the frames one-by-one. At this stage, do not connect
to your network.

o Connect 1 or 2 IEC mains cables to each frame.

o The power supplies are auto sensing for input

voltages from 90 – 260 VAC. There is no power
switch: the unit will power-up immediately.

o The two power supplies provide for main and

backup operation. If only one is connected, the
unit will show an alarm message under the Status
menu on the front panel touchscreen.

o The Gemini boot cycle takes approximately 30 seconds:

when ready, the touchscreen display shows the home
page.

11

Gemini Quick Start Guide

o Unless agreed pre-delivery, Gemini is supplied from the

factory with default network and identity settings. Before
connecting to your network, these values must be set
accordingly.

o Using the front panel touch screen, navigate to the

Settings menu.

o Choose the log-in option, then using the on screen

keypad enter the default password trilogy. Simply enter
the equivalent numbers as shown on the keys: for trilogy,
enter 8745649. Now you can change values.

o The same password is used to access Gemini using your

web browser: see page 15.

o Change the IP Address, Subnet Mask, Gateway and

Database Server addresses by pressing the small > arrow
at the end of each line and using the keypad.

o Each octet must be entered as 3 digits including all

leading zeros. So an address of 192.168.25.1 must be
entered as 192.168.025.001.

o Now set the correct EDH address, as explained in the next

section.

12

Gemini Quick Start Guide

Gemini – setting the identity (EDH address)

Each Gemini has a unique identity defined within the database by
a three part EDH address.

o EDH stands for Enterprise – Domain – Host.

o The E value is reserved for future use.
o The D value corresponds to a subnet or physical

location.

o The H value represents to an individual Gemini

matrix host.

o Typically, a single Gemini would be 0.1.1.
o Two Gemini linked locally to provide a single 64 port

matrix would be 0.1.1 and 0.1.2.

o Two Gemini linked over IP but in different locations,

would be 0.1.1 and 0.2.1.

o The EDH value is automatically generated as the database

configuration builds and cannot be edited later. Values of
D and H are shown in square brackets [ ], in the Gateway
navigation tree. If you are building a multi-host system, it
may be helpful to note these values on the IP Address
Plan created earlier.

Restart to apply changes

o These changes are only applied when Gemini re-starts.

Press the notification message on the top line of the
touchscreen and follow the prompts.

o Once Gemini has re-started, navigate to the

Settings > System menu and check that the new values
are correct.

o You can view these settings in “read-only” mode without

logging in.

13

Gemini Quick Start Guide

Connect to your network

o If the settings are correct, connect the Ethernet port on

the rear of Gemini to your network using a standard
Ethernet cable.

o On the system management PC, open the Gemini Active

Clients form from the settings icon (gears), then the View
menu.

Active Clients Form

The primary function of the Active Clients form is to send the
latest configuration from your PC to all currently connected
Gemini hosts. This is a two phase process:
o Upload: takes around 20 seconds and happens in the

background without disturbing the system.

o Restart: also takes about 20 seconds but all

communication will cease and panels will reset during
this phase.

14

Gemini Quick Start Guide

Depending on your system settings, once the upload phase is
complete, you will see a warning message asking if you wish
to go-ahead and re-start.

Follow the Upload >> Restart sequence for the single Gemini
matrix which is listed on screen.

Repeat for each Gemini in your system

If you have more than one Gemini, repeat the steps explained
on pages 9 through 13 inclusive as you add matrices one by
one.

When all Gemini hosts appear in the Active Clients Form list,
the initial set-up is complete.

15

Gemini Quick Start Guide

Gemini Web Browser

Each Gemini matrix includes a self-contained web server,
providing a range of engineering and diagnostic information.

Once Gemini is running, as outlined above, open your web
browser and type the previously configured IP address (see page

9) into the address bar.

The web pages also provide a convenient means of setting up
some additional parameters. The Settings pages are password
protected, using the same password as for the Gemini front
screen (see page 9). The default is trilogy – note that the web
pages give an option to change this password – you cannot
change the password on Gemini itself.

Next Steps……..

o Using the “basic” Host editor, define each port as 4-wire

or panel from the drop down list next to the “?” symbol.

o Give each port a suitable name: remember, most panels

can display a maximum of 5 characters.

o Using the “basic” panel editor, add keys to talk to other

panels, and to speak and listen to 4-wire circuits. Drag
and drop key targets from the palette area shown below
each panel.

o You should normally use “speak” keys to communicate

between panels.

o A range of keys are provided to both speak and listen to

4-wire audio circuits. The choice depends on your
application, but remember, 4-wire subscribers are
essentially dumb. They cannot choose to either speak or
listen.

o Save, upload, re-start and test frequently.
o To create a larger matrix, define a Gemini HSL Ring and

attach the correct Gemini host matrices. Connect the HSL
(high-speed link) cables to complete this step.

o Enhance the configuration by creating Conferences, IFBs

and Groups.
