DGX Transmitters & Receivers Instruction Manual
ESD Warning
To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure you are
properly grounded before touching any internal materials.
When working with any equipment manufactured with electronic devices, proper ESD
grounding procedures must be followed to make sure people, products, and tools are as free of
static charges as possible. Grounding straps, conductive smocks, and conductive work mats
are specifically designed for this purpose.
Anyone performing field maintenance on AMX equipment should use an appropriate ESD field
service kit complete with at least a dissipative work mat with a ground cord and a UL listed
adjustable wrist strap with another ground cord. These items should not be manufactured
locally, since they are generally composed of highly resistive conductive materials to safely
drain static charges, without increasing an electrocution risk in the event of an accident. ESD
protective equipment can be obtained from 3M™, Desco®, Richmond Technology®, Plastic
Systems®, and other such vendors.

DGX Transmitters & Receivers Instruction Manual
Overview and Specifications
Applicability Notice
The information in this manual applies to the four DGX Transmitter (TX) and Receiver (RX) modules
listed in the table below.
Important: These modules are compatible only with each other and with other AMX DGX Signal
Management products.
DGX TX and DGX RX Modules
* The supported analog video formats for this model TX are RGBHV, RGBS, RGsB, and Y/Pb/Pr video (Y/Pb/Pr
up to 1080p).
Product Notes
Either of the DGX Fiber TX modules listed can be paired with either of the DGX Fiber RX modules
as an end-to-end solution for transmission over single fiber or any of the modules can be used as an
integrated part of an AMX DGX matrix switcher that supports single fiber transmission. This manual
contains complete information for stand-alone use. For use in a system with a distribution matrix, see
page 25 in this manual and the distribution matrix’s Instruction Manual at www.amx.com.
The following descriptions explain how the modules work as an end-to-end solution. The TX and RX
work in the same way when used in conjunction with DGX Fiber boards in a DGX matrix switcher.
DGX Fiber TX Modules –two types of transmitter modules are available, one model is for analog
signals and the other model is for a DVI signal. The analog module receives RGBHV, RGBS, RGsB, or
Y/Pb/Pr video signals, and the DVI Fiber module receives a DVI video signal from the source device.
The modules also receive either a digital audio signal or an analog stereo audio signal from the source
device (digital takes precedence if both are connected). Both the video and audio signals are transmitted
over an SC terminated fiber cable to a DGX RX module. The RS-232 port on each TX supplies
unidirectional RS-232 serial data over the SC terminated fiber cable with the data flow in the same
direction as the video signal. In addition to supporting transmission of incoming signals, the DGX TX
modules also include a local video output connector for sending the video signal directly from the source
to a local destination device.
DGX Fiber RX Modules –two types of receiver modules are available to accept the signal from a TX
module’s SC terminated fiber cable. The DGX HD-15 RX converts the video signal to RGBHV for the
destination device, and the DGX DVI RX converts the video signal to DVI for the destination device.
Both modules feature SmartScale®(integrated EDID output scaling) to make sure the output resolution
is appropriate regardless of the type of incoming video. They also support a Manual (override) option for
setting up custom resolutions and a Bypass option. The audio on the RX is output on both the digital
audio port and the analog stereo audio port. The RS-232 port on each RX accepts any unidirectional
RS-232 serial data over the SC fiber from the TX.

DGX TX and DGX RX Module Features
Designed for use with single strand multimode fiber cable with SC connectors.
DGX technology provides a common signal transport and matrix switching layer that
transcodes between analog and digital signals; this allows compatibility among all the
AMX DGX Fiber modules and with other AMX DGX Signal Management products.
Provides secure transmission of uncompressed DVI or RGBHV up to 3,000 feet (914 m) at
resolutions up to 1920x1200 @ 60 Hz, including 1080p. This distance applies to both ends
when modules are used in a system with a DGX Matrix Switcher’s Fiber boards.
Auto-Detect on the transmitters and SmartScale®on the receivers work to automatically
recognize any device’s supported resolution and signal style parameters, allowing switching
out source devices and destination devices without manual setup.
SmartScale®is the ability to configure the scaling output by automatically selecting
destination defined resolutions; the product also has the ability to control detailed timing
parameters for customized video output formats.
EDID support and integrated EDID output scaling, which scales any incoming signal to the
EDID declared preferred resolution of the attached destination (this feature can be overridden
or bypassed).
Custom EDID settings can be loaded on each input with the use of the included EDID
Programmer.
DGX HD-15 TX has the ability to detect an incoming analog signal (video or audio) and
automatically convert it to a digital signal (this feature can be overridden).
DGX HD-15 TX supports RGBHV, RGBS, RGsB, and Y/Pb/Pr (Y/Pb/Pr up to 1080p) video
formats.
DGX HD-15 RX supports an RGBHV video format.
DGX DVI TX and DGX DVI RX support a DVI video format.
Both TX modules accept analog stereo audio signals (unbalanced stereo) or digital audio

Common Applications
AMX DGX Fiber Transmitters and Receivers pass digital or analog audio and video over fiber optic
cable from the source to display device. Fiber uses light, rather than electrical signals, to send data,
which is especially suitable for government and military facilities as it is not susceptible to non-intrusive
physical wire tapping. AMX DGX Fiber Transmitters and Receivers provide secure signal transport up
to 3,000 feet (914.4 m) without losing signal clarity making it ideal for use throughout classrooms,
auditoriums, conference rooms, hospitals, and campuses. With SmartScale®technology and simple
installation and termination of fiber cable, AMX DGX Fiber Transmitters and Receivers are the perfect
solution for commercial and residential installations.

DGX HD-15 RX Rear View
The following components are located on the rear of the DGX HD-15 RX (left to right):
Power receptacle – a 2.1 mm DC jack for connecting power (an ENERGY STAR®qualified
desktop power supply is provided).
RS-232 (serial data interface) port – 3-position screw terminal block accepts unidirectional
data transfer from the TX (source device to destination device).
Video Output – HD-15 connector for an RGBHV video output signal.
Digital Output – RCA jack for a digital audio output signal.
Stereo Output – standard 3.5 mm jack for an analog stereo audio output signal.
SC Fiber Input – accepts a standard 2.5 mm SC fiber connector (standardized in TIA-568A)
that snaps in.
Warning: Do not use the Stereo output connector as a headphone jack. The Stereo output is set at
unity gain (line-level) and is not intended for headphones.
Special Product Information
If a video signal is not present on the TX, the lasers are disabled and will not transmit any video, audio,
or serial data to the RX.
A short lapse/drop of the serial data is to be expected under certain instances, e.g., when the digital audio
is unplugged or plugged or when the sample rate frequency of the digital audio changes.

DGX DVI RX Front View
The following components are located on the front of the DGX DVI RX (left to right):
Power LED – indicates whether or not the module is powered on.
Video and Audio LEDs – indicate the presence of video and audio signals through the
module.
Scaling button and LEDs – use Scaling button to select one of the 3 Scaling options: Bypass,
Auto, or Manual.
USB port (mini-B) – connect to a control PC and use for overriding automatic conversion
settings, signal adjustment, if necessary, firmware upgrades through an Upgrade Tool, live
status updates, and error code reporting.
Important: If the indicator LEDs do not respond with a normal display as stated in the table below,
see “Troubleshooting” on page 57.
* When a USB cable is connected, the Power LED blinks red while communication is being established with the
PC (see page 67).
** If the output cable is disconnected from the RX or if no EDID can be found on the destination device, the
Bypass LED will be constant green and the Auto LED will blink. This indicates that the RX has switched to the
Bypass Scaling option and is waiting for EDID information. As soon as a valid EDID is found, the RX will revert to
the Auto Scaling option.
