HDMI, VGA/YPbPr, and Serial over Single Fiber

1.0 General

Thank you for purchasing the Hall Research HR-733 fiber-optic video

Extender. The HR733 is a 3 input multi-format HD video extender with

bi-directional RS-232 extension and control.

The device can select among 2 HDMI (or DVI) inputs and 1 VGA (or

YPbPr) input and extend the selected source as an uncompressed digital

signal over a single multi-mode fiber to a remote receiver. The device

supports embedded audio on the HDMI inputs, and provides separate R/L

analog or SPDIF (TOSLINK) digital audio inputs for the VGA input.

The HR-733 can also extend a bi-directional data channel (CEC, or RS-

232 Serial) over a single multi-mode (OM2 or OM3) fiber optic cable

spanning distances of up to 1000m (3280ft).

The compact remote unit provides an HDMI output (with embedded

audio) for simple AV connectivity to any display.

The RS-232 port can be used as an extension, or at the same time it can be

used to control the Sender (e.g. to select inputs). A user-friendly front

panel with high-contrast alphanumeric LCD enables the user to easily set

up and control the system.

Advanced features include: automatic scaling of the analog video input to

match the native resolution of the remote display, diagnostic messages on

the front panel LCD (e.g. RS-232 strings sent or received), audio delay of

the analog input to correct lip-sync, support for CEC data channel of

HDMI (choice of RS-232 or CEC extension), and 3D deep-color HDMI

1.4 support (without ARC or Ethernet extension).

The Sender unit is designed as a ½ wide 1RU with threaded holes so that

two can be mounted side by side on a tray (Model RMS-1U-1A), or a

single unit can be rack mounted using supplied brackets (pair of F10375).

3.0 Precautions

This device is a Class 3R Laser device

(per IEC 60825-1:2007) and can cause

damage to eye sight if used improperly.

Refer to ANSI Z136 for proper handling

and usage of Class 3R devices.

This device is sensitive to Electrostatic

Discharge (ESD). Prior to touching the

unit (especially the connectors), touch a

grounded object, and make sure the

devices that will be plugged in to the

HR-733 are properly grounded.

HDMI, VGA/YPbPr, and Serial over Single Fiber

4.0 Theory of Operation

The Sender provides both digital (HDMI/DVI), and analog (VGA/YPbPr

+ audio) inputs. However, in the fiber video is transmitted as digital

regardless of the selected input, and always comes out as HDMI on the

receiver with audio embedded in the video on the same connector. When

the analog input is selected, its video and audio are digitized and scaled to

match the native resolution of the remotely connected LCD.

The video data is transmitted on only one multi-mode fiber. The reason

multi-mode cable is needed is because the TMDS data are transmitted

over a range of optical wavelengths to reduce bandwidth requirement at

any particular wavelength. The TMDS signals use LED lasers to drive the

cable. However, for safety reasons, these lasers are not turned on if no

fiber optic cable is plugged in at both the Sender and Receiver.

Additional (non-video) DVI or HDMI signals are also seamlessly

connected between the source and the sink device. These include:

DDC Channel (SDAT and SCLK) for EDID and HDCP

Hot Plug Detect (to detect remote monitor connection)

Source Active +5vDDC (to indicate to sink there is a source)

In addition, the fiber-optic link provides a general purpose bi-directional

data lane that can be assigned by the user to be used as RS-232 pass-

through between sender and receiver, or to extend the CEC standard of the

HDMI. Currently CEC is seldom used in pro-AV installations, and its

implementation varies from one TV manufacturer to another, so as default

the HR-733 uses the data lane for RS-232 communication and control.

However, the CEC can be selected by the user, in which case the RS-232

port on the remote unit will not serve any function (the RS-232 port on the

Sender can still be used for source selection).

5.0 Installation

5.1 Required Cables

1 or 2 HDMI cables to connect up to 2 HDMI sources to the HR-

733-S

HDMI cable to connect the HR-733-R to the HDMI display

HD-15 male-to-male VGA cable to connect a PC analog video or

an HD-15 to 3-RCA for component YPbPr DVD video

connection to the HR-733-S

3.5mm stereo audio cable or optical (TOSLINK) audio cable to

connect associated audio of VGA/YPbPr source to the sender

RS-232 DB9 male-to-female (pin to pin) cable to connect the

HR-733-S’s serial port to a PC

Multi-mode (MM) fiber-optic cable to connect the HR-733-S and

HR-733-R

5.2 Inputs & Outputs

The HR-733-S has 2 HDMI inputs, 1 VGA/YPbPr input with audio, and a

bi-directional RS232 port. The audio source of the VGA/YPbPr input can

be either 3.5mm L/R stereo or optical.

The HR-733-R has l HDMI output and 1 bi-directional RS232 port.

5.3 Fiber Optic Cable Requirements

Each end of the HR-733 uses a single SC connector and requires a multi-

mode fiber-optic cable. Unlike some other fiber-optic equipment that may

work with either single-mode or multi-mode cables,

the HR-733 is not compatible with single-mode

cables. Multi-mode cables are generally available in

OM1, OM2, or OM3 constructions. The OM3

cables are best suited for max transmission lengths

and are recommended for this product.

The above table shows the maximum possible cable lengths based on data

rates for 1080p resolution with normal 8-bit color per HDMI 1.2a, as well

as deep color per HDMI 1.3 or 1.4, versus different cable constructions.

The max specified distances disregard inter-pair skew. A maximum inter-

pair skew of 0.6 * Tpixel (as required by HDMI specifications) would

limit the max distance to 600 meters regardless of cable construction at

1080p resolution. However, most HDMI equipment can tolerate skews

larger than that.
