GD-37
1. Description
The GD-37 is a programmable and manageable pre-recorded messages and background music player over Ethernet via a
built-in webserver.
Suitable for commercial uses as well as for security sound systems in venues with large numbers of people, where the
broadcast of automatic, emergency and evacuation notices (among others) is required.
The GD-37 digital recorder allows you to digitally record and play an unlimited number of and background music (depending
on the capacity of the SD).
From the front USB it also allows the broadcas of background music (BGM), having 2 play / pause and stop buttons on the
front panel.
Scheduled playback of messages via webserver through an internal calendar creating a series of events called "Programs" in
which the characteristics associated with the message are registered as per: Start Time, End Time, Cadence, Repetition,
Activation of remote control outputs, etc.
The Webserver installed in the equipment allows functionalities such as: complete supervision of operation, activation/stop of
messages, music and programmes, programming, calendar events, programming of remote events (remote controls),
configuration of operating parameters (day and time, volume, IP-Ethernet mode, on/off, etc.).
It includes 10 programmable GPIs to associate with events or programs and launch messages automatically. It also has 10
GPOs to associate with external equipment such as UDE amplifiers to trigger warning priorities or interact with the building
control system, etc.
The GD-37 incorporates two supervised security messages, which in case of failure the equipment indicates it visually via a
Fault indicator on the front, at the same time as it closes a fault contact on therear, which can be integrated in other control and
signalling equipment.
The power supply redundant to 230Vac (others on request) and 24Vdc, allowing it to remain operational even during power
cut-offs in the main power supply system.

GD-37 basically acts as a background music player (BGM), but it allows interrupting the music broadcast to emit a
prerecorded warning, message or sound, either activated manually from the Webserver or automatically from a remote
control input or programmed through a calendar event.
5.1. DIGITAL AUDIO STORAGE
The audio content (music or messages/warnings/sounds) that the equipment plays is by default stored on an SDCARD of
type HC (CAT 10 recommended) located in the back of the equipment, previously formatted under the FAT32 system, which is
provided with the following directory structure:
• MUSIC. Contains the music files or songs in MP3 format.
• SOUND. Contiene los archivos de sonidos, alarmas, etc…, en formato WAV.
• VOICE. Contiene los archivos de mensajes de voz WAV.
• SETTINGS. It is a system folder that should not be modified that includes
the settings.bin file, the basis of all the programming and configuration of the equipment.
The front of the GD-37 has a USB 2.0 port that allows music to be broadcast, after
connecting a USB flash memory. The USB flash memory must be formatted under the
FAT32 file system. The music files to be played must be stored in a folder called "MUSIC"
which will be located at the root of the directory structure of the Flash Memory.
Before inserting the flash memory, it is essential to turn off the GD-37, connect the USB
memory and restart the GD-37, the content of the memory will be analyzed by the GD-37
and when it detects the music files the GD-37 will select them in order to be able to be
reproduced whenever the user wishes.
4. Start-up procedure
The start-up of the GD-37 is via the start-up switch, which is located on the rear of the GD-37. The start-up switch affects both
the 230VAC input and the 24V DC input.
With the equipment switched on, the GD-37 starts a start-up protocol that basically consists of a start-up of the different parts
that make up the equipment. This process can last between 20 and 30 seconds, after which the GD-37 will be available for
use.
5. Basic operation
4 The FPTServer installed in the GD-37 requires a standard ftp client that works under command line and that is usually included
in the most common operating systems (Windows includes ftp.exe).

NOTES:
Do not connect or disconnect the USB memory while the GD-37 is running, irreparable damage may occur to the USB memory or to
the GD-37 itself.
Do not connect or disconnect the SD card with the GD-37 running, irreparable damage may occur to the SD card or to the GD-37
itself.
For the correct operation of the GD-37, it is essential that the audio directories on the SD card contain at least one correct file, that is,
a “.mp3” file in the “MUSIC” folder, a “.wav” file. in the “VOICE” folder and a “.wav” file in the “SOUND” folder.
It is necessary to turn off the GD-37 before inserting a USB memory; When the equipment is turned on again, the memory content
will be analyzed and when the GD-37 detects music files, these will be selected to be played whenever the user wishes.
While the GD-37 is playing Music from a USB memory placed on the front of the equipment, the Music content present on the SD
card connected on the back will not be available.
The file system used by the GD-37, to save the information in the SDCARD and USB memory units, does not support the name of
files of more than 8 characters, so it is required that the name of the files, .WAV , .MP3, and .BIN, be limited to 8 characters as the file
name and the typical 3 characters for the extension, plus the separation period. Additionally, the GD-37 supports the use of the ID3
tag related to the song name in all .MP3 files, in order to display long names on the computer screen.
5.2. FRONT KEYS
IMPORTANT NOTE:
The PLAY / PAUSE shortcut key affects only the playback of background music, while the STOP key additionally affects
externally triggered messages (remote controls), those triggered by calendar events, etc.
5.3. OPERATING INDICATOR LIGHTS
The GD-37 has various indicator lights in the front panel that give us the following information:
1. Stand by / ON
It tells us if the equipment is operational (GREEN) or off (RED).
2. Fault
When lit (RED) indicates general failure condition of the unit or degradation of the audio files supervised (Security installations). This
indication implies the opening of the FAULT contact located on the rear side of the GD-37.
3. Music ON
When lit (RED) indicates that the music playback mode is active.
4. Message ON
When lit (RED) indicates that the message playback mode is active.
On the front of the GD-37 there are two direct access keys to music playback (PLAY / PAUSE and STOP). To play the audio files
stored in the SD card or in the USB device, it is not necessary to connect the PC to the GD-37. By manipulating the PLAY / PAUSE
keys and the STOP key, you can start, pause and stop the playback of the music files on the SD card. In the case of having a USB
device connected, the audio files on the USB device will be the ones that can start, pause, and stop playback.

an Ethernet RJ-45 connection from the GD-37 connector marked ( ). The cable can be shielded, although it is not
essential.
RJ-45
5.4. GD-37 FUNCTIONS MANAGEMENT
Control, programming, verification, etc. of the GD-37 is carried out by means of a computer accessing the Webserver that the
GD-37 itself incorporates.
5.5. ETHERNET CONFIGURATION
The GD-37 can be connected to a local network using two types of connection:
5.5.1. Cable or "Patch Cable". It is used when the GD-37 joins the local network through a router / switch /
hub or an ADSL modem / router, present in the installation and acting as Access Ports (Gateway).
This cable will be connected between the connector ( ), placed on the GD-37 rear panel, and a free Ethernet port
on the router.

NOTAS:
Para que el explorador muestre la aplicación del GD-37, la conexión de red local (Ethernet) ha de estar configurada.
Revise este manual para realizar dicha configuración (véase apartado 5.5 Configuración Ethernet). Si duda, contacte
con el administrador de su red local. Ha de tener en cuenta de que para poder acceder al GD-37 desde Internet (no
necesario para redes locales) hay varias consideraciones importantes a cumplir. Además se requerirá de personal
cualificado para realizar algunas tareas:
- Es conveniente contratar un servicio de IP Fija con su proveedor de Internet, para asegurar que el GD-37 se
encuentre siempre disponible en la misma dirección IP EXTERNA. Si ya dispone de servicio de Internet, pero es del
tipo IP Dinámica, será preciso contratar un servicio de DNS DINÁMICA. Para más detalles consulte con su
administrador de red.
- Se ha de configurar el GD-37 en modo IP MANUAL. Consulte con su administrador de la red local para que le facilite
una dirección de IP libre.
- Se deberán redirigir los puertos externos TCP (80, 1998 y 1999) hacia los puertos internos TCP (80, 1998 y 1999) en
la dirección IP con la que ha configurado previamente en el GD-37. Para realizar esta tarea será necesario contactar
con el administrador de su red local.
- El acceso desde teléfonos móviles no está garantizado.
- Dependiendo del tráfico de datos existente en la red local o del ancho de banda contratado, la carga de contenido de
datos desde el Webserver en el ordenador remoto puede verse ralentizada.
